Hazards Linked to Still Unregulated Pesticide Mixtures

(Beyond Pesticides, February 19, 2016) Pesticide mixtures are more harmful than individual pesticides, according to a University of California, Los Angeles (UCLA) study that focuses on three commonly used fumigants — chloropicrin, Telone, and metam salts. The study also concludes that, while California law requires the Department of Pesticide Regulations (DPR) and county agricultural commissioners to assess these kinds of cumulative risks when regulating pesticides, they have so far failed to do so. The report, titled Exposure and Interaction — The Potential Health Impacts of Using Multiple Pesticides: A Case Study of Three Commonly Used Fumigants, was published by the Sustainable Technology and Policy Program, based in the UCLA School of Law and the UCLA Fielding School of Public Health. The case study of the three fumigants, which are commonly applied together in California on high value crops, such as strawberries, tomatoes, tree nuts, and stone fruits, finds that: These pesticides may interact to increase the health risk for California farm workers and residents, Workers and residents are regularly exposed to two or more of these pesticides simultaneously, and DPR does not regulate the application of multiple pesticides to prevent or decrease risks to human health, despite having authority to […]

Congressional Reps Want EPA Review of Glyphosate-2,4-D Mixture Enlist Duo

(Beyond Pesticides, February 18, 2016) Last week, 35 members of Congress, led by Representatives Earl Blumenauer (OR-3) and Peter DeFazio (OR-4), signed a letter to Environmental Protection Agency (EPA) Administrator Gina McCarthy, challenging  EPA’s review process for the  glyphosate  and  2,4-D  herbicide mixture, known as Enlist Duo. It is produced by Dow AgroSciences for use in genetically engineered  crops. The letter requests “more information about EPA’s plan to reevaluate Enlist Duo’s health and environmental risks.” The letter comes just weeks after the 9th U.S. Circuit Court of Appeals denied a request from EPA to vacate its own decision to  approve the  toxic herbicide cocktail. Because of the court’s decision, EPA is solely responsible for the decision about Enlist Duo’s registration. “This is part of a vicious cycle that is leading to more potent, dangerous chemicals being widely used on crops across the United States,” said  Rep. Blumenauer. He continued, “With the rise of herbicide-resistant genetically modified crops, herbicides are more widely sprayed causing weeds to grow more resistant — ultimately, requiring the application of even stronger herbicides. EPA must take action to make sure products entering the market to be used on our food are safe for human health and […]

Monsanto’s Glyphosate (RoundUp) Reported Most Used Herbicide Globally

(Beyond Pesticides, February 5, 2016) According to a report published earlier this week, Trends in glyphosate herbicide use in the United States and Globally, glyphosate, manufactured by Monsanto and known by its product name Roundup, is the most widely and heavily applied weed-killer in the history of chemical-intensive agriculture both in the U.S. and globally. Charles Benbrook, Ph.D., author of the study, which was published in the peer-reviewed journal Environmental Sciences Europe, reports that to date 18.9 billion pounds (8.6 billion kilograms) of glyphosate have been used globally, with an estimated 19% of the use coming from the U.S. The report also points out that glyphosate use has risen almost 15-fold since “Roundup Ready” genetically engineered crops (GE) were introduced in 1996. Dr. Benbrook’s research concludes that, “Genetically engineered herbicide-tolerant crops now account for about 56 % of global glyphosate use. In the U.S., no pesticide has come remotely close to such intensive and widespread use.” According to the report, two-thirds of the total volume of glyphosate applied in the U.S. from 1974 to 2014 has been sprayed in just the last 10  years. And, in 2014, enough glyphosate was sprayed to leave more than three-quarters of a pound of […]

With Zika Virus, Widespread Pesticide Spraying Not the Long-Term Solution, says Entomologist

(Beyond Pesticides, February 3, 2016) Speaking to The Guardian, a leading Kenyan entomologist warns that spraying pesticides will fail to deal with the Zika virus. Just recently the World Health Organization (WHO) declared the virus a public health emergency over growing concerns that the virus is linked with microcephaly. Aerial and ground applications of pesticides have long been used for mosquito control, but many believe that these methods fail to sufficiently control mosquito populations, promote resistance and kill other species that would have acted as a natural predator to mosquitoes. Dino Martins, PhD, a Kenyan entomologist in an interview with The Guardian said that while pesticides can reduce the population of  flying adult mosquitoes that transmit the virus, they will fail to deal with the epidemic that threatens to become a global pandemic, and warns that spraying landscapes is extremely dangerous.  “It is a quick fix but you pay for it. You kill other species that would have predated on the mosquitoes. You also create a mosaic of sprayed and unsprayed low densities of chemicals that fosters the rapid evolution of resistance.” Mosquitoes have very short life cycle (a week or less), increasing the probability that each succeeding generation is […]

Study Adds to Evidence of Endocrine-Disrupting Chemicals in Intersex Fish

(Beyond Pesticides, January 4, 2016) A study published by the U.S. Geological Survey (USGS) and U.S. Fish and Wildlife Service (FWS) found large-scale evidence of intersex in smallmouth and largemouth bass in the Northeast United States, an indicator of endocrine disruption. The study, published in the journal Ecotoxicology and Environmental Safety, looks at 19 U.S. National Wildlife Refuges and is the first reconnaissance survey of this scope. The study found that the prevalence of testicular oocytes across all samples was 85% and 27% for male small- and largemouth bass, respectively. Intersex occurs when one sex develops characteristics of the opposite sex. In the case of this study, researchers found testicular oocytes ””female eggs found inside male testicles””in male smallmouth and largemouth bass. The study explains, “The presence of oocytes in the testes of male gonochoristic fish has been used as an indicator of estrogenic exposure.” The source of the estrogen is hard to pinpoint, but pesticides are often cited as a cause given that they widely pollute waterways that  fish populate. Those chemicals have properties that disrupt the endocrine system and affect the reproductive system, causing development issues such as testicular oocytes. According to USGS, “Intersex is a global issue, […]

Herbicides and Endocrine-Disrupting Chemicals Linked to Decline of Smallmouth Bass

(Beyond Pesticides, December 18, 2015) One of the most likely causes for the population decline of smallmouth bass in the Susquehanna River are endocrine-disrupting compounds and herbicides, concludes a multi-agency, multi-year study of one of the most complex river systems in Pennsylvania. The Pennsylvania Department of Environmental Protection (DEP) and the Pennsylvania Fish and Boat Commission (PFBC), along with nearly 50 participants and six partner agencies, released findings on Monday that narrow the likely causes from an initial field of 14 candidates to two. PFBC also found that pathogens and parasites are probable contributing factors. Following a smallmouth bass (SMB) population crash in 2005, and additional observed maladies, such as tumors and lesions on SMB, the team used ground-breaking monitoring strategies to collect more than 30,000 water quality records annually, along with review of existing research to isolate the possible causes keeping young-of-the-year (YOY) SMB from growing to adulthood. The study provides evidence to what Beyond Pesticides suspected back in May, when PFBC confirmed that a rare malignant tumor was found for the first time on a SMB caught by an angler back in the summer of 2014. Though the findings at the time did not point to a specific […]

Increased Risk of Parkinson’s Disease Linked to Consumption of Heptachlor Contaminated Milk

(Beyond Pesticides, December 11, 2015) Milk contaminated with the long-banned and toxic organochlorine pesticide heptachlor in Hawaii has been found  in the brains of men that were more likely to develop Parkinson’s disease, according to a new study. This study adds to a large body of evidence linking pesticide exposure to Parkinson’s disease. Researchers of the study, titled “Midlife milk consumption and substantia nigra neuron density at death” and published in the journal Neurology, collected milk intake data from 1965 to 1968 for 449 men aged 45-68 years withpostmortem examinations from 1992 to 2004. Neuron density was measured in an area of the brain called substantia nigra (SN). As Parkinson’s develops, cells are destroyed in certain parts of the brain stem, particularly in the SN, a crescent-shaped cell mass. Measurements of brain residues of heptachlor epoxide, a heptachlor metabolite that is persistent and more toxic than its parent chemical, were also taken. “Among those who drank the most milk, residues of heptachlor epoxide were found in 9 of 10 brains as compared to 63.4%…for those who consumed no milk,” the researchers wrote. Neuron density was lowest in subjects who consumed the highest amounts of milk. The researchers looked at milk […]

Scientists Find Pesticide Exposure Decreases Lung Function in Children

(Beyond Pesticides, December 8, 2015) Exposure to common agricultural pesticides in early life leads to a measurable decrease in children’s lung functioning, according to researchers from the University of California, Berkeley. Organophosphate pesticides, a relatively older generation of crop chemicals still widely used on farms in California, have been associated with a broad range of diseases in both children and adults. This latest study adds to calls from health and environmental advocates to eliminate these toxic pesticides in agriculture, and move towards safer, sustainable, and organic management practices. The higher the rate of organophosphate exposure, the smaller a child’s lung capacity would be, scientists found. The UC Berkeley study traces exposure by looking at pesticide metabolites in urine five  times over the course of childhood (6 months to 5 years). Participants were part of the Center for the Health Assessment of Mothers and Children of Salinas (CHAMACOS), a longitudinal birth cohort study investigating the effects of pesticides and other environmental chemicals on the growth, health, and development of children in California’s Salinas Valley. For every 10-fold increase in pesticide metabolites measured in a child’s urine, an average of approximately 8% air function within the lungs was lost. “Researchers have described […]

EPA Revokes Registration of Toxic Pesticide Central to Genetically Engineered Agriculture

(Beyond Pesticides, November 25, 2015) In response to a lawsuit filed by environmental groups, the U.S. Environmental Protection Agency (EPA) yesterday revoked the registration of the toxic herbicide “Enlist Duo,” which contains the cancer causing 2,4-D and is central to future uses of genetically engineered (GE) crops in chemical-intensive agriculture. The marketing of this chemical in genetically engineered agriculture has become integral to the chemical industry’s response to weed resistance to the widely used herbicide glyphosate (Roundup), also identified as cancer causing this year by the International Agency for Research on Cancer (IARC). “Instead of looking for genetically engineered silver bullets that result in crop failure, we should be expanding organic agricultural systems that are productive and profitable, protect public health and the environment and slow global climate change,” said Jay Feldman, executive director of Beyond Pesticides. Approved by the agency just over a year ago, Enlist Duo is a combination of glyphosate and 2,4-D that Dow AgroSciences developed for use on the next generation of GE crops. EPA stated it is taking this action after realizing that the synergistic effects of the combination of these chemicals is likely significantly more harmful than it had initially believed, and that very […]

New Finding Says Glyphosate (Roundup) not Carcinogenic? Not so Fast

(Beyond Pesticides, November 18, 2015) Last week, the European Union’s (EU) European Food Safety Agency (EFSA) announced its determination that the popular herbicide glyphosate is “unlikely to pose a carcinogenic hazard to humans.” This is in direct contrast with findings released  earlier this year by  the World Health Organization’s (WHO) International Agency for Research on Cancer (IARC), which classified glyphosate a ”˜probable carcinogen.’  However, these seemingly conflicting conclusions from these premier scientific agencies are put into perspective by knowing that EFSA’s report is limited in that it reviewed glyphosate alone, unlike IARC which reviewed glyphosate and its formulated products (Monsanto’s Roundup) which are more relevant for evaluating risks to human health. In light of the March 2015 IARC findings —listing glyphosate as a probable carcinogen due to  sufficient evidence of carcinogenicity  based on laboratory studies, the European Commission requested EFSA consider glyphosate’s potential carcinogenicity. In its report released November 12, 2015, EFSA concludes that “glyphosate is unlikely to pose a carcinogenic hazard to humans and the evidence does not support classification with regard to its carcinogenic potential..” However, the agency notes that there are “several reasons explaining the diverging views” from IARC’s earlier conclusion. The most important difference is that […]

Bayer Will Pay Fines for Fungicide Damage to Wine Crops

(Beyond Pesticides, November 16, 2015) Bayer CropScience, the manufacturer of neonicotinoid pesticides that are linked to severe decline in pollinator populations, is expected to pay fines to multiple countries in Europe for wine grape damages associated with another of its pesticides. Citing “atypical symptoms” resulting from the use of a relatively new fungicide, Bayer initially sent out a warning to wine growers to cease use of their product. Now, Bayer is collecting data and assessing how much it will offer to wine growers for the damages its product has caused. European grape growers, including vineyards in Austria, France, Germany, Italy, Luxembourg and Switzerland, have reported deformed leaves and lower yields after using Moon Privilege, also known as Luna Privilege in some markets, from the German company’s CropScience unit. In Switzerland, losses are estimated at 80 million Swiss francs ($83.73 million), as reported by marketing group Swiss Wine to Reuters. Swiss Wine’s general secretary estimates harvest losses totaling 6.65 million kilos (14 million pounds) of grapes in 2015, or about  4.85 percent of 2014’s crop. It is also estimated that wine makers have lost approximately six million bottles of wine, with  Pinot Noir grapes and Chasselas, a white wine grape, hardest […]

Pesticide Exposure Linked to Abnormal Sperm Development

(Beyond Pesticides, November 10, 2015) Exposure to organochlorine chemicals, such as DDE and PCBs, is linked to increased rates of sperm abnormalities that may lead to fertility problems, according to a new study published in the journal Environmental Health Perspectives. This is the latest study in a long line of research implicating endocrine (hormone)-disrupting chemicals in reproductive diseases. Researchers investigated this issue by observing the blood serum and sperm quality of 90 men, aged 22-44, participating in health studies in the Faroe Islands, an archipelago under  Denmark’s control that is  located between Iceland, the UK and Norway. Faroe islanders consume a high seafood diet that often consists of pilot whale, integral historically as a  food source for the Faroese people. However, this practice exposes the Faroese to higher than average levels of environmental contaminants. For the study, data on umbilical cord blood and blood serum at age 14 was available for 40 of the participants, allowing a researchers to measure lifetime impacts. Faroese participants were screened for sperm aneuploidy, a condition which usually involves an abnormal number of X or Y chromosomes in sperm, and is suspected as contributing to congenital abnormalities and up to 50% of early pregnancy losses.

NY State Senator Calls For Statewide Triclosan Ban

(Beyond Pesticides, November 6, 2015) New York State Senator Tim Kennedy (D-NY) has called for a statewide ban on triclosan, one of the most prevalent antibacterial compounds found in common household products. Minnesota is the only state to have passed a triclosan  ban. If passed, the New York Bill (Bill S6070) would prohibit the sale of cleaning products containing triclosan, triclocarban, or derivatives of similar antibacterial compounds, and mark a clear victory for human health and safety interests within the state. Triclosan has been used for over 30 years in the U.S., mostly in a medical setting, but more recently in consumer products. Beyond Pesticides has generated extensive documentation  of the potential human and environmental health effects of triclosan and its cousin triclocarban, called on manufacturers to stop using triclosan in its products and retailers to stop carrying these products, and previously petitioned the Environmental Protection Agency (EPA) for the cancellation of registered products that contain the antibacterial pesticide. In May 2015, EPA issued its long-awaited response to the Citizen Petition filed by Beyond Pesticides and Food & Water Watch, denying the request. When introduced to the market in 1972, triclosan was confined to hospital and health care settings. Since […]

California Study Links Glyphosate Use and Environmental Injustice

(Beyond Pesticides November 4, 2015) On Monday, the Center for Biological Diversity, the Center for Environmental Health, El Quinto Sol de America, Californians for Pesticide Reform, the Center for Food Safety and the Pesticide Action Network released a report with findings that that more than half of the commercial glyphosate sprayed in California is applied in the state’s eight most impoverished counties. Glyphosate is a phosphanoglycine herbicide that inhibits an enzyme essential to plant growth.  Commonly known as Roundup, glyphosate is classified as a probable carcinogen by the World Health Organization’s International Agency for the Research of Cancer (IARC), based on sufficient evidence of carcinogenicity in experimental animals, and is currently under review to receive a similar designation from the state under California’s Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65). The report,  Lost in the Mist:  How Glyphosate Use Disproportionately Threatens California’s Most Impoverished Counties, found that 54 percent of glyphosate spraying in California is applied in eight counties, many of which are located in the southern part of the Central Valley. The analysis finds that the populations in these counties are predominantly Hispanic or Latino, indicating that glyphosate use in California is distributed unequally along […]

Lawsuit Challenges EPA on Toxic Herbicide Cocktail for GE Crops

(Beyond Pesticides, October 27, 2015) Late Friday,  a coalition of public health, conservation and food safety groups filed their opening brief in the ongoing legal challenge to the U.S. Environmental Protection Agency’s (EPA) approval of the herbicide Enlist Duo for use on genetically engineered corn and soybeans. Enlist Duo, a blend of glyphosate and 2,4-D, was approved on October 15 for use on genetically engineered (GE) crops, despite concerns for human and environmental contamination. The challenge was originally brought in November 2014, shortly after the EPA approved the controversial herbicide for 6 Midwest states. Since then, EPA has expanded its approval to a total of 15 states, with more expected. Counsel from the Center for Food Safety (CFS) and Earthjustice are jointly representing Beyond Pesticides, Center for Biological Diversity, CFS, the Environmental Working Group, the National Family Farm Coalition, and Pesticide Action Network North America. “The Enlist Duo approval violated the laws protecting our communities, land, and farms,” said George Kimbrell, Center for Food Safety senior attorney, counsel in the case. “Regulators bowed to the chemical industry, but we are committed to holding them accountable.” The groups argue that in its approval of Enlist Duo, a combination of the herbicides […]

Fresh Produce Tainted With Illegal Pesticides

(Beyond Pesticides, October 23, 2015) Tests on produce collected by California’s Department of Pesticide Regulation (CDPR) for 2014 show high levels of  illegal toxic pesticide residues. The CDPR report found 1 percent of produce containing an excess amount of pesticide residues, and an additional 5.5 percent of produce tested contained illegal residues of pesticides that are not allowed for use on that product. Additionally, the data shows residues of a banned  chemical, which was taken off the market  over 20 years in the U.S. due to health concerns related to farmworker exposure. These findings showcase issues related to  system-wide failure in  enforcement. Advocates stress that violations may continue to occur due to inadequacies in regulations governing enforcement authorities, which include warnings or low fines for violators. In raising concerns about the safety of food grown with chemical-intensive methods, advocates point to the need to expand the transition to organic agriculture for better protection of public health and safety. The highest percentage of illegal pesticides was found on cactus pads and cactus fruit imported from Mexico. Some of the other tainted fruit and vegetables include limes, papaya, summer squash, tomatillos, chili peppers, and tomatoes, also from Mexico, ginger imported from China, […]

Monsanto Faces Lawsuits on Cancer Linked to Roundup

(Beyond Pesticides, October 19, 2015) Monsanto, the major producer of Roundup (glyphosate), has found itself in hot water recently, as personal injury lawsuits pile up over the link between glyphosate exposure and non-Hodgkin’s Lymphoma (NHL). Personal injury law firms around the U.S. have found a multitude of plaintiffs and are preparing for what could be a “mass tort” action against Monsanto for knowingly misinforming the public and farmworkers about the dangers of the chemical. The latest lawsuit was filed October 14 in Delaware Superior Court by three law firms representing three plaintiffs. One plaintiff in the Delaware lawsuit, Joselin Barrera, 24, a child of migrant farmworkers, relates  her non-Hodgkin lymphoma (NHL) to glyphosate exposure. Elias de la Garza, a former migrant farm worker and landscaper diagnosed with NHL, has a similar claim. These follow other lawsuits filed last month in New York and California that  accuse Monsanto of knowing that glyphosate was hazardous to human health. Monsanto “led a prolonged campaign of misinformation to convince government agencies, farmers and the general population that Roundup was safe,” the lawsuit states. Glyphosate is touted as a “low toxicity” chemical and “safer” than other chemicals by the Environmental Protection Agency (EPA) and industry […]

Agricultural Crop Density Linked to Childhood Cancer in Midwest

(Beyond Pesticides, October 16, 2015) According to a new study, living in crop-dense regions is linked to increased leukemia and central nervous system cancers in children. Although there is a litany of scientific literature that highlights the link between pesticide exposure and childhood illness, this study is one of few that examines the relationship between residential exposures to agricultural pesticides via crop density and adverse health outcomes, and may serve as a basis for further investigation into childhood cancer rates in areas where agricultural pesticides are highly used. The study, titled Agricultural crop density and the risk of childhood cancer in the Midwestern United States: an ecologic study,  was published in the journal Environmental Health. Using crop density as a surrogate for residential exposure to agricultural pesticides, the study linked county-level agricultural census data and cancer incidence data for children between the ages 0 to 4 in six Midwestern states and found evidence of an association between childhood cancer incidence and the production of crops such as dry beans, oats, and sugar beets. Researchers found statistically significant exposure-response relationships for dry beans and total leukemias and acute lymphoid leukemias, oats and acute myeloid leukemias, and sugar beets and total leukemias.

Reproductive Health Experts Call for Action on Toxic Chemicals

(Beyond Pesticides, October 6, 2015) Last week, the International Federation of Gynecology and Obstetrics (FIGO) released a statement encouraging broad-based policy measures that prevent exposure to toxic environmental chemicals. “The global health and economic burden related to toxic environmental chemicals is in excess of millions of deaths and billions of dollars every year,” the report unequivocally states. FIGO’s statement follows a similar call to action from the American College of Obstetricians and Gynecologists in 2013 and the American Academy of Pediatrics in 2012. The piece lays out broad themes surrounding exposure to toxic chemicals, including issues of environmental justice, prenatal exposure and subsequent health effects, and overall global health and economic burden. Based on these impacts, several recommendations are submitted for obstetricians, gynecologists, midwives, women’s health nurse practitioners, nurses, and other health professionals to follow to achieve a goal of “prevention for all.” FIGO highlights how people of low-income, particularly in poverty-stricken countries, bare a higher burden of toxic exposure than richer nations. “[A]t every stage of development, the consequences of exposure to toxic chemicals —including morbidity and mortality, loss of family income and productivity, and environmental degradation— are disproportionately borne by people with low incomes,” the piece states. FIGO […]

Yale Study Links Prenatal Pesticide Exposure to Tremors in Children

(Beyond Pesticides, October 05, 2015) According to a Yale University study, prenatal exposure to the widely used agricultural pesticide chlorpyrifos is linked to tremors — involuntary contraction or twitching of muscles — in childhood. Chlorpyrifos, a broad-spectrum chlorinated organophosphate insecticide also known as Dursban, may also affect the cardiovascular and respiratory systems and is acutely toxic to bees, birds, mammals, and aquatic life. The study, titled Prenatal exposure to the organophosphate pesticide chlorpyrifos and childhood tremor  and published in the journal Neurotoxicology, measured the presence of chlorpyrifos in umbilical cord blood samples in 263 low-income, inner-city minority children. In 2001, the U.S. Environmental Protection Agency (EPA) banned residential use of chlorpyrifos, which was prominent in urban areas at the time. However, the study participants  —263 minority mothers  and their children, all from low income  communities in New York  City— were assembled in 1997,  before the ban was imposed. In  1997, the initial measure of each  child’s prenatal exposure to CPF  was taken from umbilical cord  blood. The children were then followed until approximately 11 years of age, after which they underwent a neurophysical assessment, which included a short drawing test. Researchers found that compared to all other children, those who […]

Pesticide Exposure Associated with Increased Risk of Diabetes

(Beyond Pesticides, September 22, 2015) A meta-analysis presented at the annual meeting of the European Association for the Study of Diabetes in Sweden concludes that exposure to pesticides is associated with an increased risk of diabetes. Although diabetes is long-suspected as involving an interplay between genetics and environmental factors, emerging research is revealing that contaminants like pesticides may play an important role in the pathogenesis of the disease. These findings add to a growing body of evidence demonstrating that pesticides play a key role in the development of a wide range of all-too-common diseases in the 21st century. To assess the association between pesticide exposure and diabetes, the recent research, Association between diabetes and exposure to pesticides: a systematic review and meta-analysis, examine 21 relevant studies comprising over 66,000 people. Most studies determined pesticide exposure through urinary or blood biomarker analysis, a highly reliable method of testing body burden. Exposure to any pesticide is linked to a 61% increase in diabetes. When looking specifically at type 2 diabetes, researchers found similar results, with any pesticide exposure increasing risk of developing the disease by 64%. However, researchers found that, although on the whole pesticides increased the chance of any diabetes diagnosis, […]

Harvard Meta-Analysis Ties Childhood Cancer to Pesticide Use

(Beyond Pesticides, September 15, 2015) A study released this week in the journal Pediatrics finds that children’s exposure to pesticides in and around the home results in an increased risk of developing certain childhood cancers. Researchers made their findings through a meta-analysis, reviewing 16 epidemiological studies published since 1993 on the link between childhood cancer and pesticide exposure. Based on their findings, the authors of the study suggest “”¦public health policies should be developed to minimize childhood exposure to pesticides in the home,” and that “[e]very effort should be made to limit children’s exposure to pesticides.” While most meta-analytical reviews previously conducted on the link between pesticides and childhood cancer looked at parental exposure or agricultural exposure, the current study from scientists at the Harvard T.H Chan School of Public Health focuses in on residential exposure in and around a child’s home. Authors found that cancer risks were connected most closely to the type of pesticide used and the location where it was applied. For example, while residential herbicide use was associated with an increased risk of leukemia, the link between outdoor insecticide use and childhood cancers was not found to be statistically significant. However, exposure to insecticides inside the […]

California to List Glyphosate (Roundup) as Cancer-Causing

(Beyond Pesticides, September 10, 2015) Last week, California Environmental Protection Agency’s Office of Environmental Health Hazard Assessment (OEHHA) announced that it intended to list glyphosate (Roundup) and three other chemicals as cancer-causing chemicals under California’s  Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65). Glyphosate  is a phosphanoglycine herbicide that inhibits an enzyme essential to plant growth. Under California law, Proposition 65 requires that certain substances identified by the International View postAgency for Research on Cancer (IARC) be listed as known cancer-causing chemicals. In March, a study by the IARC classified glyphosate as a Group 2A material, which means that the chemical is carcinogenic based on sufficient evidence of carcinogenicity in experimental animals. The agency considered the findings from an EPA Scientific Advisory Panel report, along with several recent studies in making its conclusion. However, industry supporters of glyphosate all over the globe are conducting their own studies to attempt to prove that it is not a carcinogen. These studies, like one by German Federal Institute for Risk Assessments (BfR), are based almost solely on industry science and classified industry reports, each of which might not consider critical variables. With more glyphosate-focused studies being released, the growing evidence […]
