(Beyond Pesticides, July 22, 2010) In a press release submitted last week, the Monsanto Company, Inc. announced that it has taken a vital step towards commercializing a new soybean product that is tolerant to the neurotoxic pesticide dicamba by completing its regulatory submission to the U.S. Department of Agriculture (USDA) for dicamba-tolerant soybeans. Monsanto expects to complete regulatory submission to the USDA and key global markets in the coming months. The dicamba tolerance trait is expected to also be stacked with the glyphosate-resistant, or “Roundup Ready” soybean trait upon commercialization. While Monsanto claims that this is a “highly effective and economical weed control package,” it is likely to be similar to Roundup (glyphosate) Ready crops, just another way to sell more pesticide product. Monsanto is banking on the idea that mixing dicamba with glyphosate will help manage the hard-to-control broadleaf weeds in chemical-intensive farming systems, targeting both pre-plant and post-emergence weed control in an effort to reduce resistance. In a report published last year, analysts found that genetically engineered (GE) crops have been responsible for an increase of 383 million pounds of herbicide use in the U.S. over the first 13 years of commercial use of GE crops (1996-2008). The […]

(Beyond Pesticides, July 21, 2010) Alaska’s Supreme Court halted plans to use glyphosate to kill weeds along track owned by the Alaska Railroad, which is believed to be the only herbicide-free stretch of rail in the country. This decision is in response to an emergency petition filed by Alaska Community Action on Toxics (ACAT) and others against the Alaska Department of Environmental Conservation and the Alaska Railroad Corporation (ARC) who requested the use of glyphosate for weed control. On June 2, 2010, ACAT joined with other community groups in challenging a permit that would allow the Alaska Railroad to spray toxic herbicides along the railbelt from Seward to Indian for the first time in 26 years. On July 14, 2010, the court ordered a temporary temporary restraining order and prelminary injunction for the planned spray program, in response to an emergency petition (and memorandum of points and authorities) filed by Alaska Community Action on Toxics, Alaska Center for the Environment, Alaska Survival, Cook InletKeeper and the Native Village of Eklutna. The Alaska Railroad Corporation requested permission to use the herbicide glyphosate, the active ingredient in Roundup and Agri-Dex, along a 90 mile stretch of its track between Seward and Indian.

(Beyond Pesticides, July 20, 2010) Washington state has denied approval of the highly toxic fumigant-based pesticide methyl iodide, and environmentalists hope other regulators follow its lead. Citing unreasonable adverse effects on human health and the environment, the Washington Department of Agriculture requested that Arysta LifeScience withdraw its application for the registration of methyl iodide on July 15, 2010. Beyond Pesticides encourages its California members and allies to contact the Governor’s office and ask that California, which is expected to make its final decision on the pesticide this month, follow Washington’s lead. All are encouraged to contact the U.S. Environmental Protection Agency (EPA) and ask that it reevaluate its decision to register methyl iodide. Find instructions for contacting the governor and EPA below. In a letter to Arysta LifeScience, Erik Johansen, Special Pesticide Registration Program Coordinator for the Washington Department of Agriculture stated, “WSDA is concerned that the proposed use of Midas products labeled in Washington could cause unreasonable adverse effects on human health and the environment.” Specific concerns stated in the letter include: potential for groundwater contamination; lack of data related to the pesticide’s ability to damage brain development; and cancer risk. Methyl iodide is promoted by the pesticide industry […]

(Beyond Pesticides, July 16, 2010) Under pressure from the grassroots group Alaska Community Action on Toxics (ACAT), the city of Anchorage canceled plans to spray the herbicides 2,4-D and dicamba on the Town Square Park citing concerns over the safety of children playing in the park. ACAT members attended the Anchorage Assembly public meeting with an NBC TV affiliate and discussed their reservations over spraying Town Square Park, a popular gathering place for families, workers eating their lunches, and tourists. Soon after, the mayor announced the spraying would be canceled, and that the city would remove dandelions by hand. Environmentalists called the decision a victory for the health of Anchorage residents and the environment. 2,4-D is associated with a host of adverse human impacts, such as non-Hodgkin’s lymphoma, endocrine disruption, reproductive and developmental effects, as well as water contamination and toxicity to aquatic organisms. It is one of the most widely used herbicide for the control of broadleaf weeds in commercial agriculture and residential landscapes in the U.S. About 46 million pounds of 2,4-D are used annually, with 16 million pounds used in non-agricultural settings, including parks, playing fields, and residential lawns. Its health risks prompted a Special Review in […]

(Beyond Pesticides, July 15, 2010) Swiss chemical manufacturing giant Syngenta, one of the makers of the commonly used and heavily scrutinized pesticides atrazine, are speaking out against anti-pesticide activists and the U.S. Environmental Protection Agency’s (EPA) review of atrazine. Despite mounting peer-reviewed scientific literature and research, Syngenta refuses to acknowledge the dangers of atrazine and, according to Legal Newsline, claims that the review is “redundant,” and merely “an unprecedented war on agriculture by anti-pesticide activists.” The company, which made over $11 billion in sales in 2009 even accuses the Natural Resources Defense Council (NRDC), which has spearheaded a campaign to persuade EPA to initiate reviews, of being “slick” and “well-funded.” Other critics of the agency’s decision include the American Council on Science and Health (ACSH), a group that has in the past received funding from Monsanto and Union Carbide (according to the group Center for Science in the Public Interest, ACSH stopped disclosing corporate donors in the early 1990’s). Dr. Gilbert Ross, medical director of ACSH told Legal Newswire that they believe EPA Administrator Lisa P. Jackson to be “cooperating with, if not spearheading, a broad-based activist agenda.” An article by The Huffington Post Investigative Fund published last week, however, […]

(Beyond Pesticides, July 14, 2010) The U.S. Environmental Protection Agency (EPA) announced that Monsanto Company Inc. has agreed to pay a $2.5 million penalty to resolve misbranding violations related to the sale and distribution of cotton seed products containing genetically engineered (GE) pesticides. This is the largest civil administrative penalty settlement ever received under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA). “This agreement shows that when a company violates the law by distributing misbranded pesticides, EPA will take action,” said Cynthia Giles, assistant administrator for EPA’s Office of Enforcement and Compliance Assurance. “The regulated community should understand that we take these violations seriously, and the public will accept nothing less than compliance.” “People who manufacture and distribute pesticide products must follow the federal registration requirements,” said Steve Owens, assistant administrator for EPA’s Office of Chemical Safety and Pollution Prevention. “These requirements are critical to preventing the development and spread of insect resistance.” Monsanto Bollgard and Bollgard II cotton seed products contain genetically engineered pesticides known as plant incorporated protectants (PIPs), which are registered as a pesticidal product under FIFRA. As a condition of the registrations, EPA included planting restrictions on Bollgard and Bollgard II, which contain the PIP Bacillus […]

(Beyond Pesticides, July 12, 2010) A study comparing the quality (measured in fat and protein content, egg white and shell thickness, and other physical characteristics) of various types of chicken eggs, including conventional, free-range and organic, failed to examine pesticide residues or vitamin content, nor does it consider the environmental and health impacts of conventional, chemical-based production systems, according to food and environmental safety advocates. The study is receiving attention after a recent article in Time magazine points out that organic eggs are often three times more expensive than conventional factory farm eggs. The study concludes that there is no substantial quality difference between eggs produced under different production systems. The study, “Physical quality and composition of retail shell eggs,” which was originally published in the March 2010 issue of the journal Poultry Science, compares white and brown large-shell eggs with various production and nutritional differences such as traditional, cage-free, free-roaming, pasteurized, nutritionally-enhanced (omega-3 fatty acids), fertile and organic. The study examined two dozen eggs of each variety taken from two Athens, GA grocery stores on three separate occasions. ARS food technologist Deana Jones and her team in the agency’s Egg Safety and Quality Research Unit, found that on average, […]

(Beyond Pesticides, July 9, 2010) Researchers at Swansea University in the UK have discovered a naturally occurring fungus as an alternative to pesticides for a wide range of crops. The fungal biological control agent, Metarhizium anisopliae, performed very well against the larvae of western flower thrips and vine weevils when applied as a spray or premixed into the growing medium. The researchers were able to achieve almost total control of the pest by combining the Metarhizium with nematodes, making it a huge environmental success. Professor Tariq Butt, who led the ongoing research at Swansea observed, “The benefits are far reaching””not just for those with organic farms or nurseries but also for conventional growers, offering an effective, environmentally friendly alternative to chemicals.” Professor Butt, from the University’s School of Environment and Society, believes this new development could help reduce the use of pesticides and their impact on the environment while reducing costs for farmers. The project was funded by the Department for Environment, Food and Rural Affairs under the UK Horticulture LINK program, the government’s main vehicle for sponsoring applied research in horticulture. You can read the official university press release here. The fungus has been registered in Europe with Novozymes, […]

(Beyond Pesticides, July 7, 2010) Long-term exposure to nitrates, a common agricultural water contaminant, through food and water may increase an older woman’s risk of thyroid disease, a recent study in Iowa finds. Public water supplies contaminated with nitrates increased the risk of thyroid cancer in the women. Eating nitrates from certain vegetables was also linked to increases in thyroid cancer and hypothyroidism, one type of thyroid disease. Nitrate is a common contaminant of drinking water, particularly in agricultural areas where nitrogen fertilizers are used. High rates of fertilizer application may also increase the natural nitrate levels found in certain vegetables, such as lettuce and root crops. In the body, nitrate competes with uptake of iodide by the thyroid, thus potentially affecting thyroid function. This is the first study to show a link between nitrates and thyroid cancer in people, although nitrates have been shown to cause thyroid tumors in animal studies. Researchers at the National Institute of Health, in a study entitled, ”Nitrate intake and the risk of thyroid cancer and thyroid disease,” investigated the association of nitrate intake from public water supplies and diet with the risk of thyroid cancer and self-reported hypothyroidism and hyperthyroidism in a cohort […]

(Beyond Pesticides, July 6, 2010) A review report published last Friday highlights that some research studies indicate that pesticide exposure either prior to conception, during pregnancy or during childhood appears to increase the risk of childhood cancer, with maternal pesticide exposure during pregnancy being most consistently associated with childhood cancer. Furthermore, the report notes that several studies indicate that farmers are at greater risk of developing certain cancers than the general population. In particular, several studies strongly suggest that pesticide exposures are associated with some cases of non-Hodgkin’s lymphoma (NHL), leukemia, prostate cancer and other hormone related cancers. The report, A Review of the Role Pesticides Play in Some Cancers: Children, farmers and pesticide users at risk?, is published by the United Kingdom organization CHEM (Chemicals, Health and Environment Monitoring) Trust. “Pesticide exposures may interact with other chemical exposures and genetic factors, to cause cancer. Research suggests that pregnant women, in particular, should avoid direct exposure to pesticides, if possible,” said Gwynne Lyons, Director of CHEM Trust and report co-author. “It is high time that the UK was more supportive of EU proposals to take a tougher approach to reducing exposure to potentially harmful chemicals. If the UK is to […]

(Beyond Pesticides, June 30, 2010) The U.S. Environmental Protection Agency (EPA) approval process for thousands of antimicrobial products is woefully inadequate, according Public Employees for Environmental Responsibility (PEER). Despite a growing body of scientific evidence about the side-effects of these products, EPA rubberstamps registrations without duly considering an array of potential public health and environmental impacts. Antimicrobials are now a billion dollar business with more than 5,000 such products currently registered with EPA. Initially designed for hospitals and clinics, antimicrobial pesticides are today found in products ranging from household cleaners to mattresses and bedding, cosmetics, toys, toothpaste and even chopsticks. Antibacterial products are being marketed to the health conscious without firm evidence of real benefits and amid growing concern about downstream consequences. One prime example of this is the antibacterial pesticide triclosan that is formulated into hundreds of personal care products, toys and textiles. Studies show that triclosan is an endocrine disruptor, accumulates in human fatty tissue and can influence the onset of bacterial resistance. Beyond Pesticides, Food and Water Watch and several other groups petitioned FDA in 2009 and EPA in January 2010, calling for the ban of triclosan citing the possibility of bacterial resistance to antibacterial substances and […]

(Beyond Pesticides, June 29, 2010) Based on a flawed assessment, the authors of recent study out of the University of Guelph in Ontario, Canada have been attacking organic agriculture as less environmentally friendly than chemical-intensive conventional methods. In their press release, the authors say, “Consumers shouldn’t assume that because a product is organic it’s also environmentally friendly.” However after analyzing the study, Beyond Pesticides determined that this message is flawed and misleads consumers because the study does not actually evaluate an organic system. Instead the study substitutes natural pesticides that are approved in organic systems for synthetic pesticides in a conventional soybean field. The authors warned policy makers against promoting organic agriculture, based on the false assumptions of their study. “If the goal of their study was to educate consumers as their message to the media suggests, then the authors of this study have shown a surprising lack of knowledge about organic agriculture,” said Beyond Pesticides project director John Kepner. “Organic agriculture is based on pest prevention and soil health. Organic farmers use techniques such as crop rotation and the creation of habitat for beneficial species, with organic-approved natural pesticides only as a last resort. Substituting these chemicals into a […]

(Beyond Pesticides, June 28, 2010) A new report documents high levels of pesticide drift in the California community of Sisquoc. Poison Gases in the Field: Pesticides put California families in danger, released by Pesticide Action Network North America and local community members, presents results of community air monitoring for fumigant pesticides in the central coast area of California, in Santa Barbara County. Using a simple monitoring device called the Drift Catcher, community members measured levels of a fumigant pesticide above the California Department of Pesticide Regulation’s (DPR) “level of concern” — even when all application rules were followed and no equipment failure occurred. “While we were monitoring the air, there were no violations of the County’s permit – and yet we found we were still breathing chloropicrin at high levels,” says Deby DeWeese, one of the community members who collected air samples. “Clearly the rules and regulations do not protect our families.” The Sisquoc monitoring, conducted during and after a soil fumigation in April 2008, found the pesticide chloropicrin in about half of the 57 air samples collected. Two samples had chloropicrin levels higher than DPR’s 24-hour level of concern for children, and the 19-day average level at one sampling […]

(Beyond Pesticides, June 25, 2010) Two new studies published in the journal Environmental Science and Technology confirm that the majority of toxic contamination threatening national parks originates from agricultural pesticides and industrial operations. In one study an international group of scientists conducted research from 2003-2005 and detected elevated concentrations of various dangerous pesticides in all eight of the national parks and preserves. The other study collected samples of air, water, snow, sediment, lichens, conifer needles, and fish at remote alpine, subarctic, and arctic sites. Researchers found that these samples contained four current-use pesticides including dacthal (DCPA), chlorpyrifos, endosulfans, and y-hexachlorocyclohexane (HGH) as well as four historic-use pesticides including dieldrin, a-HCH, chlordanes, and hexachlorobenzene (HCB). Pesticide concentrations in snow are highest in Sequoia, Kings Canyon, Rocky Mountain and Glacier National Parks. Concentrations in vegetation are mostly dominated by endosulfan and dacthal, and are highest in Yosemite, Kings Canyon, Glacier, and Great Sand Dunes National Park and Preserve. Fish samples also show elevated concentrations of dieldrin and DDT (one of the first pesticides to be banned in 1972 because of Rachel Carson’s Silent Spring). Cold temperatures in alpine or arctic ecosystems tend to concentrate pesticides, which can also bioaccumulate in the local […]

(Beyond Pesticides, June 24, 2010) Our food purchases have a direct effect on the health of our environment and those who grow and harvest what we eat. Beyond Pesticides launched its Organic Food: Eating with a Conscience guide, which shows consumers why, according to the group, “food labeled organic is the right choice.” Jay Feldman, executive director of Beyond Pesticides, said, “In addition to serious health questions linked to actual residues of toxic pesticides on the food we eat, our food buying decisions support or reject hazardous agricultural practices, protection of farmworkers, and stewardship of the earth.” The Eating with a Conscience guide explains to consumers the effect they are having on health and the environment when they purchase food grown with chemical-intensive methods, even if a large number of residues do not remain on the finished food product. The group points to USDA organic certification as “the only system of food labeling that is subject to independent public review and oversight, assuring consumers that toxic, synthetic pesticides used in conventional agriculture are replaced by management practices focused on soil biology, biodiversity, and plant health.” “Organic practices under the Organic Foods Production Act eliminate commonly used toxic chemicals in the […]

(Beyond Pesticides, June 18, 2010) A panel of U.S. and Vietnamese policy makers, scientists, and citizens released a report on Wednesday urging the U.S. government and other donors to provide $300 million to clean up contaminated sites and care for Vietnamese harmed by exposure to Agent Orange, an herbicide used by the U.S. to defoliate large swaths of forest during the Vietnam War that was contaminated by dioxin. Dioxin is a very persistent toxicant that clings to the soil and sediments, and bioaccumulates in the food chain. Many studies have linked dioxin exposure to a myriad of health effects including cancer, neuropathy, diabetes, Parkinson’s Disease, and birth defects. This report comes one month before the U.S. and Vietnam will celebrate 15 years of normalized diplomatic relations. The U.S.-Vietnam Dialogue Group on Agent Orange/Dioxin released the report calling for an estimated $30 million annually for the next 10 years. Since 2007, the U.S. has spent only $9 million on dioxin remediation and assisting disabled Vietnamese. The report lays out a plan with three phases. The first phase, lasting three years and estimated to cost $100 million, would focus on completing remediation in Da Nang, one of the largest contaminated sites. This […]

(Beyond Pesticides, June 17, 2010) Researchers have found detectable levels of common household pesticides in the majority of umbilical cord blood of babies born at an urban hospital. The study looks at concentrations of organophosphate (OP), carbamate, pyrethroids, and organochlorine pesticides in samples of umbilical cord blood taken from newborns delivered at the Johns Hopkins Hospital Labor and Delivery Suite in Baltimore. Researchers looked at the umbilical cord serum, as opposed to maternal serum, in order to provide a more direct estimate of exposure to the fetus. While human biomonitoring studies have found detectable levels of these pesticide chemicals in urine and blood samples from children and adults in the past, few studies have been carried out in the U.S. evaluating exposure in utero. In addition to tracking pesticide concentrations, researchers also aimed to identify demographic and socioeconomics factors associated with in utero pesticide exposure. Anonymous anthropometric and sociodemographic characteristics of the mothers and infants were collected along with umbilical cord blood that would have otherwise been discarded. Included in the characteristics collected that researchers considered might affect pesticide exposure risk were: age, race, body mass index, parity, education, health insurance, marital status, smoking, area of residence and housing density. […]

(Beyond Pesticides, June 16, 2010) Men with certain genetic variations who were exposed to some toxic pesticides that are now largely banned run an increased risk of developing Parkinson’s disease, French scientists said Monday. In a study published in Archives of Neurology, entitled “Interaction Between ABCB1 and Professional Exposure to Organochlorine Insecticides in Parkinson Disease,” French researchers found that among men exposed to pesticides such as DDT, carriers of the gene variants are three and a half times more likely to develop Parkinson’s than those with the more common version of the gene. The scientists think the brains of people with the gene variant fail to flush out toxic chemicals as efficiently as those with common versions of the gene, suggesting that environmental as well as genetic factors are important in the risk of Parkinson’s. Alexis Elbaz, MD, PhD and Fabien Dutheil, PhD, of France’s National Institute for Health and Medical Research (INSERM) studied 101 men with Parkinson’s and 234 without the disease to look at links between organochlorine exposure and Parkinson’s disease. The study includes only men, and all of them had high levels of exposure to pesticides through their work as farmers. The scientists found the link was […]

(Beyond Pesticide, June 11, 2010) The Environmental Protection Agency (EPA) has refused the state of Ohio’s request for an emergency exemption to use the restricted pesticide propoxur in residential settings for control of bed bugs, stating that the chemical “presents unreasonable risk.” Propoxur is a highly toxic, broad spectrum insecticide. All indoor residential uses of this known neurotoxic chemical and possible carcinogen were voluntarily canceled in 2007. The Ohio Department of Agriculture, deeming the increases in bed bug infestations an emergency, requested an exemption to use propoxur in residential areas and in May the Ohio Senate’s Environment and Natural Resources Committee adopted a unanimous resolution urging the EPA to grant it. Beyond Pesticides, with coalition of environmental and public health groups, opposed the request and asked EPA to deny the exemption, citing the serious public health threat associated with the chemical, as well as the availability of alternatives. EPA determined “the requested use presents an unacceptable risk,” according to Administrator Lisa Jackson, in a letter to Ohio Governor Ted Strickland dated June 2, 2010. “Although EPA recognizes the severe and urgent challenges that Ohio is facing from bed bugs, the results of the risk assessment do not support the necessary […]

(Beyond Pesticides, June 10, 2010) After years of pressure from environmental and international groups concerned about the chemical’s health effects, the U.S. Environmental Protection Agencey (EPA) announced that it is taking action to end all uses of the insecticide endosulfan in the United States. EPA has decided that new data presented to the agency in response to its 2002 reregistration eligibility decision (RED) have shown that risks faced by workers are greater than previously known. EPA also has found that there are risks above the agency’s level of concern to aquatic and terrestrial wildlife, as well as to birds and mammals that consume aquatic prey which have ingested endosulfan. Farmworkers can be exposed to endosulfan through inhalation and contact with the skin. An organochlorine insecticide first registered in the 1950s, endosulfan is used on a variety of vegetables, fruits, cotton, and on ornatmental shrubs, trees and vines. It poses unacceptable neurological and reproductive risks to farmworkers and wildlife and can persist in the environment. According to the EPA, crops with the highest use in 2006 — 2008 included tomato, cucurbit, potato, apple, and cotton. The use of endosulfan decreased overall from 2001 to 2008. A restricted use pesticide, endosulfan may […]

(Beyond Pesticides, June 7, 2010) With thousands of violations cited, the pest control company and applicator responsible for the deaths of two young children are only fined several tens of thousands of dollars, a mere slap on the hand. The Utah Department of Agriculture and Food’s (UDAF) Division of Plant Industry has finally filed multiple charges of violations against Bugman Pest and Lawn, Inc. of Bountiful, Utah, and employee Cole Nocks associated with the February 5, 2010 application of the pesticide Fumitoxin (active ingredient: aluminum phosphide) at the residence of Nathan and Brenda Toone of Layton, Utah that lead to the death of their two daughters ages 15-months and 4 years. In addition to the Layton incident, investigators discovered additional violations of the Utah Pesticide Control Act by the company and other employees. The UDAF seeks to revoke Mr. Nocks’s applicator license and has issued him a $27,000 fine, while Bugman Pest and Lawn, Inc. is fined $32,000. Under law, the UDAF is only allowed to file civil penalties. Investigators determined that on February 5, 2010 applicator Cole Nocks operated in a faulty, careless or negligent manner by misapplying the highly toxic and restricted use pesticide, Fumitoxin. Mr. Nocks’s improper […]

(Beyond Pesticides, June 2, 2010) After decades-long litigation over the use of the toxic pesticide dibromochloropropane, or DBCP, in the 1970’s which has been linked to sterility and has since been banned, Dole Food Co. is proposing new settlements for farm workers claiming they were injured by exposure to the pesticide. A request has been filed by lawyers for Dole in the Los Angeles Superior Court asking that nearly 1,500 Honduran farm workers who are suing Dole be allowed to drop out of those suits and settle their claims out of court under an existing program arranged by the company and Honduran government officials. This could potentially end years of legal action inexpensively for Dole while providing compensation to workers quickly, however some people view this plan as a way for the company to back out of its responsibilities to former plantation workers. The pesticide DBCP was used by workers from Nicaragua, Costa Rica, Guatemala, Honduras, and Panama to kill worm infestations in the trees’ roots. In the U.S., DBCP was used as a soil fumigant and nematocide on over 40 different crops until 1977. According to the U.S. Environmental Protection Agency (EPA), DBCP causes male reproductive problems, including low […]

(Beyond Pesticides, June 1, 2010) Atrazine, one of the most commonly used herbicides in the world, has been shown to affect reproduction of fish at concentrations below U.S. Environmental Protection Agency’s (EPA) water-quality guideline, according to a new U.S. Geological Survey (USGS) study. “Concentrations of atrazine commonly found in agricultural streams and rivers caused reduced reproduction and spawning, as well as tissue abnormalities in laboratory studies with fish,” said USGS scientist Donald Tillitt, Ph.D., the lead author of the study, “Atrazine Reduces Reproduction in Fathead Minnow (Pimephales promelas)” published in Aquatic Toxicology. Fathead minnows were exposed to atrazine at the USGS Columbia Environmental Research Center in Columbia, Missouri, and observed for effects on egg production, tissue abnormalities and hormone levels. Fish were exposed to concentrations ranging from zero to 50 micrograms per liter of atrazine for up to 30 days. All tested levels of exposure are less than the EPA Office of Pesticides Aquatic Life Benchmark of 65 micrograms per liter for chronic exposure of fish. Study results show that normal reproductive cycling was disrupted by atrazine and fish did not spawn as much or as well when exposed to atrazine. Researchers found that total egg production was lower in […]
