(Beyond Pesticides, May 10, 2018) Rodenticides like bromadiolone, used to kill vole populations on farms, act like “super-predators” that imperil ecosystem health, according to preliminary results published by researchers working for the European Union. “Controlling voles with bromadiolone reduces the amount of food available to predators and increases their risk of secondary poisoning when they eat the contaminated rodents,” project researcher Javier Fernandez de Simon, PhD, said in a press release. The study provides a model that may alleviate the impact of rodenticide use and provide a balance between on-farm pest management and sustainability. There are several types of rodenticides available on the market, including acute poisons like strychnine, fumigants like phosphine gas, and anti-coagulants such as warfarin and bromadiolone. Anti-coagulants, the focus of the present study, work by blocking the ability of the body to form blood clots. Animals exposed to bromodialone and other anti-coagulants experience ruptured blood vessels, hair loss and skin damage, nosebleeds, and bleeding gums prior to death. These pesticides are generally applied through secured bait boxes that only allow rodent pests to feed, however secondary poisoning is a common occurrence, leading researchers to dub these rodenticides, in effect, as “super-predators.” Rodents that ingest anti-coagulant pesticides […]

(Beyond Pesticides, May 9, 2018) An insect’s gut microbiome plays an important role in conferring pesticide resistance, according to a new review published in the Annals of the Entomological Society of America. “Whether you’re looking at agricultural pests, household pests like cockroaches, or medical pests like disease-carrying mosquitoes, insects are great at adapting to whatever we throw at them, especially when it comes to different chemicals,” said lead author Jose Pietri, Ph.D to Entomology Today. The review adds to the numerous ways pests can evade the effects of chemical agriculture, reinforcing calls from recent studies showing that the best method of addressing this issue is to simply stop using synthetic pesticides and employ alternative pest management practices. The authors identify two overarching methods through which microbes help confer resistance to toxic pesticides. The first involves the pest accepting a physiological trade-off, where a pest is able to better withstand an insecticide at the cost of losing its ability to regulate certain gut bacterium. For instance, diamondback moths resistant to fipronil and chlorpyrifos are found to contain higher levels of Lactobacillales, Pseudomonadales, and Xanthomonadales bacteria than non-resistant moths. While this trade-off affects the fitness of the organism, alterations of the bacterial […]

(Beyond Pesticides, May 4, 2018) Environmental Protection Agency (EPA) Administrator Scott Pruitt proposed a new rule, on April 24, that, if adopted, will restrict the use of certain kinds of science research in the agency’s writing of regulations. Titled “Strengthening Transparency in Regulatory Science,” the rule will permit EPA to consider only research studies for which the underlying data are publicly available when considering new “significant” regulations — typically, those estimated to impose costs of $100 million or more. Supporters of the rule say that EPA has, in crafting regulations in the past, relied on “secret science” — studies for which the underlying data cannot necessarily be accessed by members of the public. At face value, this may sound reasonable. Administrator Pruitt and proponents call the proposed rule a plus for transparency that will boost public confidence in the science bases of EPA decision making. “Today is a red-letter day,” Mr. Pruitt told supporters at agency headquarters. “The science that we use is going to be transparent.” That so-called “transparency,” however, comes at a huge cost: the elimination of decades of scientific studies from consideration when EPA regulations are written. In studies over the past few decades, researchers frequently collected data — […]

(Beyond Pesticides, May 3, 2018) Hawaii’s bill to ban the dangerous, neurotoxic pesticide, chlorpyrifos, passed its final hurdle this week in the state legislature. Governor David Ige is expected to readily sign SB3095 into law, in light of the unanimous support it received from lawmakers on both sides of the aisle. The statewide prohibition of chlorpyrifos will take effect beginning in January 2019. This legislative action marks the first time that any state in the country has passed an outright ban on the highly toxic organophosphate pesticide. While multiple scientific studies have determined that chlorpyrifos damages fetal brains and produces cognitive and behavioral dysfunctions, particularly in utero and in children, states have been slow to institute a complete prohibition, due to its widespread use in agriculture. Lawmakers in New Jersey and Maryland have recently tried unsuccessfully to pass similar bans. Hawaii’s bill contains a caveat that allows the state’s Department of Agriculture (DOA) to grant special permits for companies that argue that they need more time to phase-out chlorpyrifos, but that exemption will end at the close of 2022. The new law also requires restricted use pesticide (RUP) users to report to the Hawaii’s DOA which ones they are applying on […]

(Beyond Pesticides, May 2, 2018) Granola, cereal, and wheat crackers all contain “a fair amount” of glyphosate, the herbicide in Monsanto’s popular Roundup, according to internal emails from the Food and Drug Administration (FDA). Although the results of these tests have not been formally released, FDA had stated it will be conducting tests for glyphosate in food. Previous reports have detailed the presence of glyphosate, the chemical classified as a “probable carcinogen,” in a wide range of foods and in people’s bodies. Internal emails obtained by The Guardian through a Freedom of Information Act (FOIA) request reveal communication between FDA scientists regarding glyphosate residues in common foods. One email, dated January 2017, detail one scientist’s results from foods taken from his own home. “I have brought wheat crackers, granola cereal and cornmeal from home and there’s a fair amount in all of them,” FDA chemist Richard Thompson wrote to colleagues in the email last year regarding glyphosate. He further went on to write that broccoli was the only food he had “on hand” that he found to be glyphosate-free. According to The Guardian, another FDA chemist Narong Chamkasem separately found “over-the-tolerance” levels of glyphosate in corn, detected at 6.5 parts per million, an FDA […]

(Beyond Pesticides, May 1, 2018) On April 27, 2018, European Union (EU) member states backed a proposal to further restrict uses of bee-toxic neonicotinoids finding the pesticides’ outdoor uses harm bees. These restrictions go beyond those already put in place in 2013, and now all outdoor uses of clothianidin, imidacloprid, and thiamethoxam will be banned. Uses will only be allowed in permanent greenhouses where contact with bees is not expected. This historic move in Europe comes as the U.S. Environmental Protection Agency (EPA) still drags its feet on finding neonicotinoids are too toxic for bees and other organisms and bans their use. According to the European Commission, the protection of bees is an important issue since it concerns biodiversity, food production, and the environment. An EU committee approved the plan to tightly restrict the use of the insecticides, acting upon scientific advice this past February from the European Food Safety Authority (EFSA) to tighten existing restrictions and protect bees, crucial pollinators. EFSA analyzed over 1,500 studies from academia, beekeeper associations, chemical companies, farmer groups, non-governmental organizations, and national regulators, and concluded that neonicotinoids do pose risks to honey bees and wild pollinators. In 2013, the EU placed a ban on […]

(Beyond Pesticides, April 27, 2018)  After more than five years of intensive negotiations, European Members of Parliament (MEP) overwhelmingly passed the long-anticipated, new organic certification and labeling regulations, with 466 voting in favor, 124 against and 50 abstentions. While the European Union (EU) Council of Ministers, must formally adopt the regulations, their easy passage is expected. Regulations will take effect in January 2021. The new organic regulations are purported to provide more clarity to organic producers and consumers and to harmonize organic regulation across the EU. But, they also are likely to fuel disharmony with the U.S. National Organic Program (NOP) by failing to act swiftly to curtail fraudulent organic exports and by prohibiting hydroponics systems of production in organic, which the US currently allows. “The development of organic production is a political objective of the EU,” According to the EP’s background document on the regulations. As a strategy for increasing organic agriculture, which now encompasses 6.7% of EU agricultural land, MEPs intend for the new regulations to encourage more farmers to go organic, enhance consumer trust in the EU organic logo, and improve the quality of organic food. According to the European Parliament’s press release, “Strict, risk-based checks will take […]

(Beyond Pesticides, April 26, 2018) Each year, the Environmental Working Group (EWG) publishes its Shopper’s Guide to Pesticides in Produce™. The guide includes the “Dirty Dozen” and “Clean 15” lists of conventionally grown produce items that, respectively, are the most heavily tainted by toxic pesticide residue, and by contrast, have little if any residue. EWG analyzes testing conducted by the U.S. Department of Agriculture’s (USDA’s) Pesticide Data Program to arrive at its annual assessment. Its report for 2018 found that nearly 70% of conventional produce is contaminated with residue and/or breakdown byproducts of one or more of the 230 pesticides that USDA evaluated. The top items on the 2018 Dirty Dozen list include strawberries, spinach, nectarines, apples, and grapes. One-third of all the strawberry samples harbored 10 or more pesticides, and one sample showed residue of 22 different compounds. Pesticide contamination was found in 97% of spinach samples, 94% of nectarines, 90% of apples, 96% of grapes, and 99% of peaches. Topping the 2018 Clean 15 list of the least-toxic conventionally grown produce items are avocados (99+% of samples tested negative for pesticides), sweet corn (98+%), pineapples (90%), onions (90+%), and cabbage (86%). EWG again this year added hot peppers as […]

(Beyond Pesticides, April 25, 2018)  A class-action lawsuit against two manufacturers of neonicotinoid insecticides is moving ahead in Quebec, Canada after an appeal to block the case by the Canadian government and the chemical companies, Bayer and Syngenta, was dismissed. In February 2018, the case, brought by a beekeeper, was allowed to proceed to trial by the Quebec Superior Court. Quebec queen bee breeder, Steve Martineau, conducted tests on water and his dead and dying bees and found traces of neonicotinoids. His suit alleges that Bayer and Syngenta were negligent in the manufacture and sale of neonicotinoids in Quebec, and are responsible for damages that he and other class members suffered under Article 1457 of the Quebec Civil Code. Bayer and Syngenta challenged the application on a number of grounds including the assumption that they had manufactured the neonicotinoids which killed Martineau’s bees. The class in this case was authorized for all persons in Quebec who own or owned bees in the affected area since 2006. Mr. Martineau estimates he has lost about $20,000 a year to present due to the effects of neonicotinoids on his bee population (Martineau v. Bayer CropScience Inc. CALN/2018-007) “We’re suing on behalf of Quebec beekeepers whose bees were […]

(Beyond Pesticides, April, 24, 2018) On April 19, 2018, an Appellate Court in California sided with the State of California, affirming that Monsanto’s glyphosate can be listed as a probable carcinogen under the state’s Proposition 65 and rejecting Monsanto’s challenge to law. The state will not only move ahead with warning labels on products that contain glyphosate but also prohibit discharge of the pesticide into public waterways. Monsanto’s lawsuit challenged the 2015 decision by California’s Office of Environmental Health Hazard Assessment (OEHHA) to list glyphosate, the active ingredient in Monsanto’s herbicide, Roundup, under California’s Proposition 65. Proposition 65 requires notification and labeling of all chemicals known to cause cancer, birth defects or other reproductive harm, and prohibits their discharge into drinking waters of the state. In 2015, the International Agency for Research on Cancer (IARC) of the World Health Organization (WHO) concluded that glyphosate is “probably carcinogenic.”  Under the Labor Code listing mechanism of Proposition 65, substances identified by IARC must be listed in the state of California as known to cause cancer. This listing requires warning labels on products and the listed substances are subject to limits on discharges into surface waters. California added glyphosate to the list of cancer-causing chemicals in July […]

(Beyond Pesticides, April 23, 2018) The U.S. Environmental Protection Agency (EPA) is accepting comments on its human health and environmental risk assessments of glyphosate (sold as Roundup™, Rodeo™, and many other products) until April 30. Evidence is mounting that glyphosate products cause cancer and many other human health and environmental problems. Sign the petition asking EPA to ban glyphosate. Despite the prevalent myth that this widely used herbicide is harmless, glyphosate is associated with a wide range of illnesses, including non-Hodgkin’s lymphoma, genetic damage, liver and kidney damage, and endocrine disruption, as well as environmental damage, including water contamination and harm to amphibians. Researchers have also determined that the “inert” ingredients in glyphosate products, especially polyethoxylated tallow amine or POEA –a surfactant commonly used in glyphosate and other herbicidal products— are even more toxic than glyphosate itself. Monsanto, manufacturer of glyphosate, formulates many products (such as Roundup™ and Rodeo™) and markets formulations exclusively used on genetically engineered (GE) crops. Glyphosate is one of the most widely used herbicides in the world, due in large part to the increased cultivation of GE crops that are tolerant of the herbicide. This petition summarizes the reasons glyphosate should be banned. More information can be […]

(Beyond Pesticides, April 19, 2018) With the passage yesterday of the Republican amendments to the 2018 Farm Bill, H.R. 2, in the U.S. House of Representatives’ Agriculture Committee, Congress has launched a full-frontal attack on the Endangered Species Act (ESA) and required pesticide reviews to protect endangered species. According to the Center for Biological Diversity (CBD), the bill, on a party-line vote, will “completely exempt the use of pesticides from ESA, effectively dooming hundreds of endangered species to extinction and making it legal to kill any endangered species with a pesticide at almost any time.” The legislation is sponsored by House Agriculture Committee Chairman U.S. Representative Mike Conaway (R-Texas). The Farm Bill’s ESA provision will do away with EPA’s legally-mandated scientific consultations with the National Marine Fisheries Service (NMFS) and the Interior Department’s Fish and Wildlife Service (FWS), the two main agencies charged with government oversight of species protection. If Congress fails to eliminate this undesirable provision from the Farm Bill, it is viewed as a tragic end to a success story, which began with the enactment of ESA in 1973. The law effectively prevented the extinction of 99 percent of species under its jurisdiction over the past 45 years. Few federal laws […]

(Beyond Pesticides, April 18, 2018) A new report from the Union of Concerned Scientists (UCS), Betrayal at the USDA, concludes that a myriad of personnel and policy decisions by Trump administration Secretary of Agriculture Sonny Perdue, in his first year, are harming the public. Enacted through the U.S. Department of Agriculture (USDA), these decisions have weakened public safety and health protections, ignored science, and advantaged agribusiness interests over those of the public, farmers, and rural communities. Given the mission of USDA — to provide “leadership on food, agriculture, natural resources, rural development, nutrition, and related issues based on sound public policy, the best available science, and efficient management” — the U.S. population would understandably expect that the agency would make good on that mission. People might assume the agency would employ sound science in promoting innovative, sustainable agricultural practices, and in helping maintain a domestic food system that ensures a safe and healthful food supply, supports farmers’ success, and protects the natural resources on which both of those depend. UCS concludes that, in the Trump era, people would be wrong. USDA has considerable, albeit not-always-obvious, impact on people’s everyday lives. As the Union of Concerned Scientists (UCS) notes, “The agency’s programs and […]

(Beyond Pesticides, April 13, 2018) Hawaii is poised to become the first state in the nation to prohibit the use of pesticides containing the developmental neurotoxicant, chlorpyrifos. SB3095, passed unanimously by the State House of Representatives this week, prohibits the application of restricted use pesticides (RUPs) within 100 feet of schools when they are in session, and it requires commercial agricultural entities to regularly report their RUP use to the Department of Agriculture (DOA). In the absence of adequate federal procedures to protect communities from hazardous pesticide drift, this bill represents the culmination of efforts by the people of Hawaii to ban and restrict the most egregious pesticides and to increase the transparency regarding their use. As bill supporters rallied in the Capitol’s Rotunda this week, SB3095 was sent to the Senate. No date has yet been set for its consideration, but Senators who support the bill hope to secure the 13 votes needed to pass it and avoid further weakening of its provisions. Beyond Pesticides has actively supported this and previous iterations of SB3095, arguing for the establishment of a much more protective one mile buffer zone between schools and RUP applications to safeguard school children where they learn.

(Beyond Pesticides, April 12, 2018) The Justice Department will allow two notorious agrichemical corporations, Bayer and Monsanto, to merge, according to reports published earlier this week. Despite strong voices of opposition from grassroots advocates across the country, and investigations by state Attorneys General, the over $60 billion merger was approved after Bayer agreed to sell off select sectors to another competitor, BASF.  The merger will make Bayer the largest seed and pesticide company in the world. While lining the pockets of C-suite executives, farmers will be hurt by decreased competition and greater costs, which will ultimately affect consumer prices for food. China, Brazil, Australia, and the European Union (EU) signed off on the deal prior to U.S. approval. As part of EU negotiations, Bayer agreed to divest $7 billion, selling off its soybean and cottonseed sectors, as well as its glufosinate herbicide division, which competes with Monsanto’s Roundup. Bayer also promised European regulators that it would not attempt to foist genetically engineered (GE) crops onto European consumers.  The U.S. Justice Department added additional requirements, noting that widespread use of GE crops in America meant there would be different considerations. According to reports, Bayer will need to sell off additional seed […]

(Beyond Pesticides, April 11, 2018) The request by shellfish growers in Washington State to apply the neonicotinoid insecticide, imidacloprid, on oyster and clams beds to control native burrowing shrimp was denied by the Department of Ecology (Ecology) after it determined “environmental harm from this neonicotinoid pesticide would be too great.” Concerned resident and environmental advocates have been opposed to the proposed use citing harms to aquatic life including fish habitat, and long-term ecological damage. Shellfish growers from Willapa-Grays Harbor Oyster Growers Association requested a permit from the state to use the imidacloprid on burrowing shrimp that the growers said impede traditional shellfish cultivation. They sought a state National Pollution Discharge Elimination System (NPDES) permit to apply imidacloprid to 500 acres of shellfish beds within Willapa Bay and Grays Harbor, over a period of five years. The growers first applied for a permit in 2015 to treat 2,000 acres of tidelands, but after a strong public outcry, they withdrew the request. In 2016, they applied for a new permit to treat less acreage and Ecology published a draft Supplemental Environmental Impact Statement (SEIS) in 2017 on the potential impacts imidacloprid application would have to the bay. Now, Ecology, after thoroughly evaluating […]

(Beyond Pesticides, April 3, 2018) Humans’ unsustainable exploitation of natural resources, worldwide, has reached critical proportions, threatening the ability of an estimated 3.2 billion people to have food and water security, according to a new international study. The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services report (IPBES) unearths the crisis faced by two-fifths of the world’s population due to the worsening of land degradation, declining species biodiversity, and the intensification of climate change. While the report presents a bleak picture of how humans have substantially degraded the natural resources essential to survival, it also offers some hope by identifying the changes could be adopted by governments with a political will. Publication of the IPBES comes with a stern warning from the report’s Chair, Robert Watson, PhD, who cautions that “the time for action was yesterday or the day before.” The extensively peer-reviewed report, conducted by 100 experts from 45 countries, represents a compilation of four regional assessments in the Americas, Asia and the Pacific, Africa, and Europe and Central Asia. It is intended to provide policy makers with “the best available evidence” to make important decisions about corrective actions they can take to avoid, reduce, and even reverse land degradation […]

(Beyond Pesticides, March 28, 2018) The Integrated Pest Management (IPM) in Healthcare Facilities Project, spearheaded by the Maryland Pesticide Education Network (MPEN) and Beyond Pesticides, are marking the Project’s 10th anniversary to reduce healthcare facilities’ pesticide use and impact, while maintaining a high level of pest management. Funded by Maryland-based foundations, the IPM in Healthcare Facilities Project services are pro bono. Maryland healthcare facilities strive to provide a high level of pest management to protect the compromised health of the at-risk people they serve, however often and unknowingly, many healthcare facilities respond to pest problems by having their contracted pest management vendors apply toxic pesticides as a first line of defense. These chemicals are often linked to the very issues for which patients are being treated. Pesticides can cause acute life-threatening reactions and linked to long-term impacts including cancer, asthma, Parkinson’s’ disease, developmental, reproductive and neurological impacts and immune dysfunction issues. The IPM staff, in collaboration with fourteen Maryland facilities, have worked diligently to reduce facilities’ pesticide use and impact, while maintaining a high level of pest management. Project staff educate facilities’ management and technicians about the dangers of patient pesticide exposure and the benefits of implementing an IPM program. An […]

(Beyond Pesticides, March 27, 2018) In a major win for farmworker and health groups, the U.S. District Court for the Northern District of California ruled last Wednesday the U.S. Environmental Protection Agency (EPA) illegally delayed implementation of key pesticide rules that in part prevent minors from working with the most dangerous pesticides. The rule revised rules mandate pesticide applicators be at least 18 years old. According to the EPA, there are about one million certified applicators nationwide. Before delaying implementation, the agency said the revised rule could prevent some 1,000 acute poisonings every year. In addition to requiring applicators to be at least 18-years-old, the revised 2017 Certification of Pesticide Applicators (CPA) rule also improves the quality of training materials and says certified pesticide applicators must be able to read and understand the instructions. The main purpose of the CPA rule is to protect workers and the public from poisonings, by ensuring that those who handle the most dangerous pesticides are properly trained and certified. “We commend the court for recognizing that this important pesticide safeguard is needed to prevent injury to farmworkers and the public,” said Stacey Geis, Earthjustice managing attorney. “This ruling puts EPA Administrator Scott Pruitt on notice that the courts […]

(Beyond Pesticides, March 26, 2018) Tell your state AG to join the investigation of the merger of Bayer-Monsanto, the manufacturer of genetically engineered seeds tolerant of its herbicide glyphosate (aka Roundup®), and Bayer, the manufacturer of neonicotinoid insecticides responsible for pollinator declines, including imidacloprid and clothianidin. The giant seed and pesticide company that would be created by this merger would be a disaster for pollinators, people, and the environment. Farmers overwhelmingly think this mega-merger is a bad idea –a new survey and white paper were released that demonstrate widespread opposition of farmers to this merger. According to the poll, which was conducted by a coalition of farm organizations, 93 percent of farmers surveyed oppose it. More than one million Americans have called on the Department of Justice to stop it. Investigations are ongoing in both the EU and the U.S. Your state attorney general could play a key role in this fight by joining the investigation. Tell your state AG to join the investigation of the Bayer-Monsanto Merger! If this merger goes through, the new company would be the world’s largest vegetable seed company. It would control seeds for many of the crops we eat regularly — including broccoli, carrots, and onions. It would also be the largest manufacturer […]

(Beyond Pesticides, March 23, 2018) French scientists and ornithologists say parts of the country’s forests, streams, and bucolic landscapes could be completely devoid of birdsong this year, as the results of two recent studies show staggering declines in bird populations throughout the nation linked to the intensification of agricultural practices and pesticide use. The advent of so many significant wildlife declines at the same time –now recognized in birds, but also seen in pollinators and insect populations–is leading many to wonder whether the modern world has forgotten the warnings of Rachael Carson’s Silent Spring back in 1962. “We’ve lost a quarter of skylarks in 15 years. It’s huge, it’s really, really huge. If this was the human population, it would be a major thing,” said Benoit Fontaine, PhD, of France’s National Museum of Natural History and co-author of one of the new studies to The Guardian. “We are turning our farmland into a desert. We are losing everything and we need that nature, that biodiversity – the agriculture needs pollinators and the soil fauna. Without that, ultimately, we will die.” The French National Museum of Natural History and the National Centre for Scientific Research each conducted an investigation into country’s bird […]

(Beyond Pesticides, March 22, 2018) Last week Environmental Protection Agency (EPA) Administrator Scott Pruitt received a letter from twenty-eight U.S. Senators urging the preservation of rules that would protect farmworkers and disallow minors to handle highly toxic pesticides. At issue are two proposals from Administrator Scott Pruitt’s EPA that would roll back Agricultural Worker Protection Standards (AWPS) and the Certification of Pesticide Applicators (CPA) rules put in place during the Obama Administration. In their letter, the Senators stress the impact of any potential changes, noting “the lives of children and families across the country at stake.” During the Obama era, EPA completed rulemaking that revised AWPS for the first time in over 20 years. Key components expanded training, prohibited children under 18 from applying highly toxic restricted use pesticides, created new no-entry application-exclusion zones, improved record keeping, provided farmworkers a designated representative to request pesticide records, and other safety improvements. The final rules put in place long-overdue protections, but still represented a compromise for workers and farmworker advocates. At the time the rules were released, advocacy organization Farmworker Justice released a statement noting, “While we are disappointed that the final rule does not include some significant safety measures, we will […]

(Beyond Pesticides, March 15, 2018) On Tuesday, a group of 56 scientists studying the effects of neonicotinoids sent a letter to California’s Department of Pesticide Regulation (CDPR) highlighting the threat neonicotinoids pose to the health of California’s waterways. The scientists urge CDPR to take steps to reduce neonicotinoid contamination of the state’s streams and rivers. This comes as neonicotinoids were recently reported to be pervasive throughout the Great Lakes, and federal assessments confirm high risks to aquatic species. According to the letter, neonicotinoids are already found in California waterways at levels that exceed the freshwater invertebrate aquatic life benchmarks and could harm or kill many sensitive aquatic invertebrate species. Citing a 2016 study by the Xerces Society that found imidacloprid frequently in California’s rivers and streams at levels harmful to species such as mayflies and caddisflies. Imidacloprid samples in California from 2010-2015 showed that 42% (197 of 468) of detections exceeded the acute invertebrate benchmark and all of the detections exceeded the chronic invertebrate benchmark. In certain regions of the state, particularly agricultural areas, the imidacloprid benchmark for acute effects was more frequently exceeded. The scientists note these chemicals can “have consequences for broader ecosystems. Declines in aquatic invertebrates put other species […]
