(Beyond Pesticides, January 3, 2017)  A study published in December 2016 in Environmental Contamination and Toxicology, entitled The Effect of Atrazine on Louisiana Gulf Coast Estuarine Phytoplankton, finds that phytoplankton in estuaries in close proximity to agricultural operations are less productive than phytoplankton in an uncontaminated environment. The study examines three different estuaries of the Mississippi river in Louisiana and also evaluates microcosms with different concentrations of atrazine. Phytoplankton, incredibly important to estuary ecosystems and aquatic life, are an integral part of the aquatic food web and ultimately critical to the wild seafood market. As photosynthetic microorganisms, phytoplankton harness the sun’s energy for metabolism and create as a byproduct of photosynthesis dissolved oxygen, which oxygen-breathing sea life require. For the study, the researchers created microcosms, or large containers that are able to closely mimic ecosystems, so that they can observe the effects of independent variables. On average, phytoplankton in the microcosms are less productive at producing chlorophyll a in the presence of atrazine. The microcosm study design is important because it is difficult to separate and measure the effects of chemicals like atrazine in the environment, given the range of potential causes of phytoplankton decline. A variety of factors, like freshwater discharge rates, precipitation, […]

(Beyond Pesticides, November 10, 2016) In the wake of the monumental decision to elect Donald Trump as the 45th President of the United States, Beyond Pesticides’ work to protect public health and the environment is more critical than ever. On Tuesday, November 8, 2016  saw Mr. Trump prevail in winning the presidency, and Republicans hold on to their majorities in both the U.S. House and the Senate. In the coming months, the President-elect will deliberate on  cabinet appointments, which will impact pesticide and agriculture policy and the laws and regulations that have the capacity to protect citizens from the harmful effects of chemical intensive practices. According to an article in Scientific American, Donald Trump may  select Myron Ebell, “one of the best-known climate skeptics” and director of the Center for Energy and Environment at the Competitive Enterprise Institute, to lead his U.S. Environmental Protection Agency (EPA) transition team. This represents a  blow to  the environmental movement, which has been building momentum to fight global climate change, transition to organic agricultural systems, and protect the public from the threat of corporate mergers that threaten farmers, rural communities, and consumers. Despite having few details on environmental policy, it is clear from Donald […]

(Beyond Pesticides,  November 7,  2016) In a letter  last week on the widely used weedkiller  atrazine, Rep. Ken Buck (R-CO) and 105 of his colleagues told Gina McCarthy, administrator of the U.S. Environmental Protection Agency (EPA), that, “It would be irresponsible to greatly restrict one of the safest and most trusted herbicides on the market.” The  letter was triggered by EPA’s release in June of its  draft  Ecological Risk Assessment on atrazine, which found levels of concerns exceeded by as much as 200-fold for some organisms. Lawmakers indicated that the draft assessment in its present form, “Would have a significant impact on farmers and rural communities nationwide.” Despite a wealth of information to the contrary, they claim that restricting the use of atrazine would put an unnecessary financial burden on farmers. Atrazine, produced by Syngenta,  is the second-most widely used pesticide in the U.S., with over 73 million pounds applied each year. While Rep. Buck claims that atrazine is a safe chemical, years of research shows that the chemical poses unacceptable risks to human health and the environment.  Once applied, the chemical often washes into surface water and leaches into groundwater. Water contamination issues spurred community water utilities  across the […]

(Beyond Pesticides, October 4, 2016) Chemicals previously used as  inert ingredients in pesticide formulations have been detected in a wide range of North American wildlife species, according to research published in the journal Environmental Science and Technology. The compounds, perfluroalkyl phosphinic acids (PFPIAs), were widely used as anti-foaming agents in pesticide formulations until 2006, when the U.S. Environmental Protection Agency took regulatory action to cancel  their use, citing “human health and environmental risks of concern.” However, the chemicals continue to be used today in consumer goods, including carpet cleaning formulas. While scientists did not find what they would consider high concentrations of the chemicals in wildlife, the ubiquity of the detections was found to be most concerning. Researchers detected the presence of PFPIAs in the blood of 100% of animals sampled. This includes northern pike in Montreal, Canada, cormorants from the Great Lakes, and bottlenose dolphins from Sarasota Bay, Florida. “We aimed for diversity: air-breathing versus water-breathing, differences in habitat, different taxonomic groups,” Amila O. De Silva, PhD, coauthor of the study, said to CNN. Part of the reason for the wide range of detection lies with the properties of these chemicals. They are highly stable and resist degradation from […]

(Beyond Pesticides,  September 19, 2016) Last week, a  proposed Bayer-Monsanto merger was announced, as St. Louis-based agrichemical giant  Monsanto Co. agreed to sell the company  to German pharmaceutical and chemical conglomerate, Bayer, in  an unprecedented $66 billion dollar deal. It is the merger of two companies that have been tied to past atrocities against humanity, one whose chemical product was  used  to kill  concentration camp victims under Adolf Hitler and the other a producer of the  deadly defoliant, Agent Orange, which was sprayed by the U.S. government over Vietnam and left a legacy of health damage to the Vietnamese people and U.S. veterans of the armed forces. At the same time, these companies are currently embroiled in controversy on  some of the most hazardous pesticides, including glyphosate (RoundupTM) and neonicotinoids, used in food production and in communities and home gardens    —continuing a history of profiting from a technology that has adverse effects on human life and the environment, but has been shown to be unnecessary and unsustainable in food production and the management of lawns, landscapes, playing fields, and parks. In 1995, the Associated Press reported that the then-CEO of Bayer,  Helge Wehmeier, apologized to Elie Wiesel, Ph.D., holocaust […]

(Beyond Pesticides, September 14, 2016) According to a recent study by the U.S. Geological Survey (USGS), high concentrations of dioxins and furans have been detected in tree swallow eggs collected near several sites around the Great Lakes. Other chemicals detected include polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs), which were at background levels. The study is part of efforts to clean up a toxic chemical legacy around the Great Lakes, and the researchers believe their results are critical to regulators to assess “bird or animal deformity or reproductive problems” The study, “Concentrations and spatial patterns of organic contaminants in tree swallow (Tachycineta bicolor) eggs at United States and binational Great Lakes Areas of Concern, 2010—2015,” used tree swallows to quantify current exposure to organic contaminants across all five Great Lakes including 59 sites within 27  Areas of Concern (AOCs)  and 10 nearby  locations. The Great Lakes Areas of Concern refers to a U.S.-Canada  Great Lakes Water Quality Agreement  (Annex 1 of the 2012 Protocol) that  defines AOCs as “geographic areas designated by the Parties where significant  impairment of beneficial uses  has occurred as a result of human activities at the local level.” An AOC is a location that has […]

(Beyond Pesticides, September 2, 2016) Last Sunday, beekeepers in Dorchester County, South Carolina emerged from their homes to find their yards and  farms, once full of busy buzzing, littered with the honey bees. The cause was no mystery — a massive bee-kill had occurred due to aerial spraying of Naled, a highly toxic  insecticide used primarily to control adult mosquitoes. The county announced plans to spray two days before the incident, when four travel-related cases of Zika virus were confirmed in the area by the state Department of Health and Environmental Control. The spraying occurred between 6:30 and 8:30am. Naled is an organophosphate insecticide with the highest acute toxicity of any mosquitocide. According to the Environmental Protection Agency (EPA), Naled can cause cholinesterase (an enzyme necessary to the transmission of nerve impulses) inhibition in humans, meaning that it can overstimulate the nervous system causing nausea, dizziness, confusion, and, at very high exposures (e.g., accidents or major spills), respiratory paralysis and death. Naled is highly toxic to honey bees. In Dorchester County, beekeepers say that the spray announcements did not come soon enough. Flowertown Bee Farm and Supply lost more than 2.3 million insects from 46 hives, according to co-owner Juanita […]

(Beyond Pesticides, August 25, 2016) The County of Miami-Dade announced Tuesday that it will no longer conduct aerial sprayings on weekdays, to avoid exposing children and teachers. In an effort to control the spread of Zika, the county is consulting with the Centers for Disease Control and Prevention (CDC) and the Florida Department of Health (FDOH), to spray a neighborhood in the county, Wynwood, with Bacillus thuringiensis israelensis (Bti) and Naled. Mosquito officials were conducting the spraying during the early hours of the morning, when fewer people were around, the first day of the school year in Miami-Dade started this week, putting teachers and students at risk of exposure at bus stops. The county’s move is encouraging, because as research has continuously shown, children and pesticides don’t mix.  Studies show children’s developing organs create “early windows of great vulnerability” during which exposure to pesticides can cause great damage. Childhood pesticide exposure has been linked to a range of adverse health endpoints, including cancer, asthma, impaired sexual development, ADHD and other learning disabilities. “We have adjusted our spraying schedule to avoid any inconvenience to our local school system, and the children, families, and teachers in our community,” the office of Mayor […]

(Beyond Pesticides, August 16, 2016) Young children are disproportionately poisoned by toxic pesticides used indoors, according to a study published in the Australian and New Zealand Journal of Public Health. Data analyzed from the Queensland, Australia Poisons Information Centre (QPIC) finds that 49% of 743 insecticide-related calls in 2014 concerned young children. Given that children are more sensitive to pesticide exposure than adults because they take in more of a chemical relative to their body size and have developing organ systems, this data underscores the importance of educating the general public about alternatives to the use of toxic pesticides in and around the home. A significant share of childhood pesticide poisonings occurred in very young children. “Children in the one-year age group were at greatest risk — as they’re at that stage where they spend a lot of the time on the floor and put things in their mouth,” said Karin English, PhD candidate at the University of Queensland. As a result of children’s propensity for hand to mouth motion, cockroach baits and ant liquid were found to be the most common source of insecticide exposure for kids under five, covering 39% of calls. However, Ms. English notes that enclosing […]

(Beyond Pesticides, June 29, 2016) A new report published by Regeneration Vermont finds that herbicide and chemical fertilizer use on Vermont dairy farms nearly doubled from 2002 to 2012, increasing from 1.54 to 3.01 pounds of herbicide per acre, respectively. The report, Vermont’s GMO Legacy: Pesticides, Polluted Water & Climate Destruction, by Will Allen, Ph.D. of Regeneration Vermont and Cedar Circle Farm, focuses on the failed promises of genetically engineered (GE, or GMO) crops to reduce chemical inputs required for crop production. While Vermont leads the nation on the GE labeling front, with its  law set to go into effect on July 1, the report, which highlights the flawed exemption on dairy and meat products, is a sobering reminder that this is only a part of the solution to the effects of GE crops and chemical-intensive agriculture. “While the law will force mainstream food corporations to label GMOs in products like Cheetos and Spaghetti-os before coming into the state, it turns a blind eye to the GMO-derived dairy that is the primary ingredient in, for example, Ben & Jerry’s ice cream and Cabot’s cheddar cheese,” says Dr. Allen. “This is about more than the consumer’s right to know. It’s also […]

(Beyond Pesticides, June 8, 2016) With years of data documenting the harmful impacts of the herbicide atrazine on aquatic organisms and other wildlife, a recent U.S. Environmental Protection Agency (EPA) assessment now concludes that this widely used chemical poses risks to fish, amphibians, aquatic invertebrates, and even birds, reptiles and mammals. Atrazine is a potent endocrine disruptor with strong associations with birth defects, sex reversal and hermaphroditism in organisms, and whose risk to environmental and human health is exacerbated by pervasive surface, ground and drinking water contamination. Last week, EPA released its triazine ecological risk assessments for atrazine and its chemical cousins simazine, and propazine. The assessments evaluated risks to animals and plants including, amphibians, birds, mammals, fish, reptiles, aquatic invertebrates, aquatic plant communities, and terrestrial plants.  EPA is currently in the registration review process for these chemicals. For atrazine, EPA concludes, “aquatic plant communities are impacted in many areas where atrazine use is heaviest, and there is potential chronic risks to fish, amphibians, and aquatic invertebrate in these same locations. In the terrestrial environment, there are risk concerns for mammals, birds, reptiles, plants and plant communities across the country for many of the atrazine uses.” Levels of concerns were […]

(Beyond Pesticides, May 23, 2016) At the Breaking Through Power conference today, Beyond Pesticides’ executive director, Jay Feldman, will provide a retrospective on 35 years of Beyond Pesticides’ work and outline critical needs moving forward to protect health and the environment. This historic meeting of civic engagement across national social action organizations comes at a time when bee colonies have experienced sustained losses above 40% (44% 2015-16 and 42% 2014-15). Central to the ecosystem, pollinators are essential to the viability of one-third of the food supply. Meanwhile, with the surge in genetically engineered crops, pesticide use is increasing exponentially, as herbicide use increased 4 to 18% a year, depending on the crop, over the last decade, while weed and insect resistance is growing rapidly —threatening productivity. Twenty-four species of weeds in 29 states and worldwide now exhibit resistance to the most widely used herbicide, Roundup (glyphosate). Advocates say that pesticide impacts on clean air, water, and food continue to be ignored by the chemical industry and a slow moving Environmental Protection Agency. Meanwhile, communities across the country are adopting local laws and policies that restrict pesticide use, and two states, Maryland and Massachusetts, have passed bills that ban retail sale […]

(Beyond Pesticides, May 19, 2016) Using fear without facts, Congress is yet again attempting to gut Clean Water Act (CWA) provisions that protect waterways and communities from excessive pesticide pollution. In a move that was blasted by House Democrats this week, HR 897  (which was introduced as the Reducing Regulatory Burdens Act of 2015) was renamed the  Zika Vector Control Act, despite the fact that the bill does not actually do anything to address the threat of Zika. The legislation was defeated Tuesday on a suspension vote, 262-159, however the bill will be going to the Rules Committee on Monday, with anticipated House floor activity on Tuesday, May 24. (Take action: urge your representative to oppose HR 897.) “In a brazenly political act, the Republican leadership is trying to mask gutting the Clean Water Act as having something to do with fighting Zika,” Drew Hammill, spokesman for House Minority Leader Nancy Pelosi (D-CA), said in a statement to The Hill. “This bill has nothing to do with Zika and everything to do with Republicans’ relentless special interest attacks on the Clean Water Act,” he said. “It will do nothing to stem the growing threat of the Zika virus.” The bill […]

(Beyond Pesticides, April 19, 2016) Last week the Environmental Working Group (EWG) released its annual Shoppers Guide to Pesticides in Produce, highlighting the critical importance of eating organic food to avoid pesticide residues that endanger human health. Beyond Pesticides’ Eating with a Conscience database complements EWG’s report by identifying the many additional reasons it is essential to choose organic for a healthy future. Although information on residues in conventional produce listed in the “Dirty Dozen” is helpful in alerting consumers and encouraging organic, it only tells part of the story. It turns out that even those food commodities in EWG’s “Clean Fifteen” may be grown with hazardous pesticides that get into waterways and groundwater, contaminate nearby communities, poison farmworkers, and kill pollinators and wildlife, while not all showing up at detectable levels on our food. For its report, EWG analyzed over 35,000 samples of pesticide residue collected by the U.S. Department of Agriculture. After 5 years at the top of the list, apples dropped to number two, replaced by strawberries. The organization reasons that a recent EU ban on the chemical diphenylamine, a fungicide linked to reproductive effects, kidney/liver damage, as well as groundwater contamination and toxicity to aquatic organisms, […]

(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 […]

(Beyond Pesticides, January 27, 2016) Last week the Senate Environment and Public Works Committee added an amendment to the Sportsman Act of 2015 that would remove important protections from pesticides sprayed into our nation’s waterways. After years of failed attempts to pass a version of the amendment as a stand-alone bill called the “Sensible Environmental Protection Act,” the latest attack against clean water was put forth by Senator Deb Fisher (R-NE), and passed by a committee vote of 12-8. It now moves to the Senate floor in a piece of bipartisan legislation. This amendment would reverse a 2009 federal court decision in National Cotton Council v. EPA that directed EPA to require permits from applicators who spray over “navigable waters,” as outlined in the Clean Water Act (CWA). The bill’s proponents claim that the need for water permits is duplicative, given that pesticide applicators also comply with the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA), the law that requires applicators to follow instructions on pesticide labels. However, the fact is that CWA permits let authorities know what is sprayed and when it is sprayed, so that the public may know what chemicals are used in their waterways and the potential […]

(Beyond Pesticides, November 23, 2015) Commonly-used pesticides can impact aquatic species over multiple weeks, even when chemicals are no longer detectable in water nor  monitored by regulators, according to new research. The study, titled A long-term assessment of pesticide mixture effects on aquatic invertebrate communities,  published in the journal Environmental Toxicology and Chemistry, investigates the long-term effects on aquatic invertebrate communities of commonly-used insecticides: two pyrethroids (permethrin and lambda-cyhalothrin) and an organophosphate (chlorpyrifos). Pesticide applications were based on environmentally relevant concentrations and lethal concentrations (a concentration required to kill a certain percentage of animals tested) ranging from 10% (LC10) to 50% (LC50). Researchers made repeat applications in order to mimic runoff events in a multiple grower or homeowner watershed. The results indicate that insecticide mixtures continue to impact natural systems over multiple weeks, even when bound to particles and no longer detectable in water. Combinations of indirect and direct effects caused consequences across the food chain. Pyrethroids rapidly dissipated from the water column, whereas chlorpyrifos was detectable even six weeks after application. “The effects we observed indicate that many species were affected at a sublethal level,” said Simone Hasenbein, Ph.D., lead author of the study tells Phys.org. “Thus, populations exposed […]

(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 […]

(Beyond Pesticides, October 21, 2015) Last week, Responsible Industry for a Sound Environment (RISE), an umbrella group representing pesticide manufacturers, celebrated its 25th year anniversary, touting its efforts to roll back critical protections from pesticide use in the U.S. The group emphasizes its role in quashing local government’s right to restrict pesticide use within its jurisdiction  after the Supreme Court, in Wisconsin Public Intervenor v. Ralph Mortier (1991), upheld local  authority under federal pesticide law. RISE, formed out of the National Agricultural Chemicals Association to fight government regulation at the federal, state, and local level, launched with a  plan to defeat those opposing pesticide use in favor of sustainable practices, including concerned mothers, progressive businesses, and local and national health and environmental advocates. The platform  RISE articulates  showcases its plans to influence regulators and consumers to allow the widespread and less restricted use of pesticides. In the 1990’s, RISE joined with another industry group, the American Legislative Exchange Council (ALEC), to seek the adoption in state legislatures across the country pesticide preemption laws, which were adopted in over 40  states. These laws prevent local governments from adopting  their own restrictions governing pesticide use  on private property. At one point, the […]

(Beyond Pesticides, August 31, 2015) A study published in Environmental Science and Technology, funded in part by the U.S. Geological Survey (USGS), has found that almost 2 million people are living near aquifer sites contaminated with uranium that is mobilized by human-contributed nitrate. Nitrate is a common groundwater contaminant that is sourced mainly from chemical fertilizers and animal waste. Chronic exposure to elevated levels of uranium can lead to kidney damage and cancer. These findings emphasize the dangers of synthetic fertilizer overuse, and highlight the need to switch to safer alternatives. The study, “Natural Uranium Contamination in Major U.S. Aquifers Linked to Nitrate,” analyzed approximately 275,000 groundwater samples from the Great Plains regions and California, finding that many residents often live less than a mile from uranium-contaminated wells that exceed guidelines set by the Environmental Protection Agency (EPA). In the High Plains aquifer, researchers find uranium concentrations up to 89 times EPA standards, while the Central Valley aquifer measure up to 180 times EPA standards. The study also reports that 78% of these uranium-contaminated sites are linked with the presence of nitrates. Nitrate mobilizes naturally occurring uranium through a series of reactions that oxidize the material, making it water soluble. […]

(Beyond Pesticides, August 12 2015) Last week, the City of Plattsburgh, New York, unanimously approved a policy that encourages city departments and city residents to reduce and eventually eliminate their use of toxic pesticides, such as neonicotinoids and glyphosate. In the same resolution, city residents and department heads are also encouraged to refrain from genetically modified organism (GMO) cultivation, though they recognize there is very little of that taking place within Plattsburgh city limits. While this policy can only be used to discourage the use of pesticides and GMOs, not implement an outright ban, due to preemptive New York state law that occupies the field of pesticide regulation, city officials are hopeful that they will be able to use their influence to implore the state of New York and U.S. legislators to take statewide and nationwide measures on the production of GMO crops and to curb the use of toxic pesticides. The language of the resolution, sponsored by Councilman Mike Kelly, cites the health of honey bees and other insects as one of the main reasons for encouraging citizens to refrain from the use of pesticides in the practice of lawn care and beautification. It also specifically names neonicotinoids as […]

(Beyond Pesticides, July 27, 2015) Two Michigan Representatives have introduced the Great Lakes Assurance Program Verification Act (HR 3120) in an effort to halt the pollution of the Great Lakes and other waterways by protecting them from agricultural run-off, which causes dangerous algae blooms ­. While the proposed legislation aims to reduce the effects of pesticides in water, the bill still allows the use of toxic pesticides and fertilizers, and is only a voluntary measure, something that environmentalists says falls short. The bill is sponsored by Candice Miller (R-MI) and co-sponsored by Tim Walberg (R-MI). The bill aims to mimic the state program Michigan Agriculture Environmental Assurance Program (MAEAP). Adopted in 1999, the MAEAP is a voluntary three-phase program that provides “on-farm verification to ensure the farmer has implemented environmentally sound practices.” This raises two concerns: lack of incentive for farmers to join the program and ambiguous language defining what environmentally sound means. The results of MAEAP are the driving force in the fight for federal Great Lakes legislation, but those numbers do not necessarily speak for themselves. A major goal of the MAEAP is the Farmstead System which, “focuses primarily on protecting surface and ground water” through the safe […]

(Beyond Pesticides, June 26, 2015) The agency responsible for chemical oversight in the European Union announced today that the antibacterial pesticide, triclosan, is toxic and bioaccumulative, and will be phased-out for hygienic uses and replaced by more suitable alternatives. According to the European Chemicals Agency (ECHA), “[N]o safe use could be demonstrated for the proposed use of Triclosan.” This decision has renewed calls for the U.S. Food and Drug Administration (FDA) and U.S. Environmental Protection Agency (EPA) to remove the chemical from the consumer market. EPA in May rejected a consumer petition that asked the agency to ban triclosan. “We applaud this step to protect public health and the environment,” said Jay Feldman, executive director, Beyond Pesticides. The ECHA opinion states that, “Risk was identified for both surface water and for the non-compartment specific effects relevant to the food chain (secondary poisoning).” ECHA believes that any further risk mitigation for triclosan is “not considered realistic.” Triclosan is an antimicrobial pesticide used in cosmetics, personal care products and treated plastics and textiles. It has been linked to hormone disrupting effects, bacterial and antibiotic resistance, cancer, and impacts on aquatic organisms. The chemical’s widespread consumer use raises concerns over necessity and efficacy. […]
