(Beyond Pesticides, May 24, 2018) California’s Department of Pesticide Regulation (DPR) is falling short of protecting vulnerable communities in the state, especially low-income and communities of color. This, according to a new report by California Environmental Justice Alliance (CEJA), which assesses state agencies on eight environmental justice principles. The poor showing by DPR comes at the forefront of reports that the state’s pesticide use has increased, nearing record highs. The findings are from California Environmental Justice Alliance’s (CEJA) 2017 Environmental Justice Agency Assessment, which provides full assessments of nine key agencies in the state including, California Air Resources Board, Department of Pesticide Regulation, and the Department of Toxic Substances Control, and lists an additional six agencies to monitor. The assessment gave the California Department of Pesticide Regulation (DPR) poor grades for its persistent failure to prioritize community health over industry profits. The agencies were judged on eight environmental justice principles, with a score of good, fair or poor for each. DPR’s scores were evenly divided between “fair” and “poor.” Specifically, the report concludes, “Many state agencies are not successfully integrating [environmental justice] into their decision-making. Overall, many state agencies still make decisions that actively harm [environmental justice] communities and fail to […]

(Beyond Pesticides, May 23, 2018) Earlier this month, the Connecticut state legislature voted to ban the use of residential pesticide misting systems. (These are devices that are typically placed outdoors and spray insecticides –mostly in an attempt to control mosquitoes.) This is the latest move from a state legislature that has also recently banned the use of bee-toxic neonicotinoids and stopped the use of hazardous lawn care pesticides on public playgrounds. The vote was unanimous in the state Senate, and won by a count of 132-17 in the state House. The bill is set to become law on May 24, unless Governor Malloy vetoes the legislation, which is not expected. Pesticide misters are machines primarily used to spray mosquito adulticides. Many health advocates have expressed concern that these products, able to spray toxic pesticides on a timer at regular intervals, pose a significant risk to pets and children who can be directly in the path of a mister’s spray. The chemicals employed in these machines are often synthetic pyrethroids, which have been linked to a range of human health effects, from early puberty in boys, to behavioral disorders, learning problems, ADHD, and certain cancers. Neighbors who do not want to be […]

(Beyond Pesticides, May 22, 2018)  A staggering 209 million pounds of pesticides were used in California in 2016, according to the latest data released by the Department of Pesticide Regulation (DPR). This figure refers only to applied “active” pesticide ingredients and not “inerts,” which often account for 80 to 99 percent of pesticide products and can be equally hazardous to human health and the environment. Even though pesticide use in the state has dropped by 1.4 percent from the previous year, pesticide use in 2016 was still the third highest in recorded history, since the inception of DPR’s comprehensive data collection program in 1990. In fact, the total pesticide use was only six million pounds shy of the highest amount ever recorded – 215 million pounds in 1998. The land area treated with carcinogens is as large as the size of New Jersey and Connecticut combined. Nearly 102 million cumulative acres of land were treated with pesticides in the state, ranging in toxicity from low to high risk. Each time an acre is pesticide-treated in a given year, DPR adds the acre to its cumulative list, even if the treatment is repeated on the same land. The 2016 figure represents an […]

(Beyond Pesticides, May 21, 2018)  490,000 Pounds of Toxic Pesticides Sprayed on National Wildlife Refuges in 2016 The nation’s 562 national wildlife refuges play a critical role in protecting fish, plants, and other wildlife. They include forests, wetlands, and waterways vital to thousands of species of plants and animals, including 280 that are protected under the Endangered Species Act. However, private chemical-intensive commercial farming of crops like corn, soybeans, and sorghum has become common on refuge lands, with the increasing use of highly toxic pesticides that threaten the long-term health of sensitive habitats and the creatures who depend on them. The Center for Biological Diversity (CBD) estimates that 490,000 pounds of pesticides were applied to commodity crops like corn, soybeans, and sorghum grown in national wildlife refuges in 2016, the most recent year for which data are available. Tell FWS to take toxic pesticides out of wildlife refuges. The nearly half million pounds of pesticides used on wildlife refuges in 2016 include 2,4-D, dicamba, and paraquat, all of which are toxic to fish, amphibians, crustaceans, and other animals. Also included are 116,200 pounds of glyphosate, the herbicide that has caused widespread decreases in milkweed plants, helping to trigger the 80 percent […]

(Beyond Pesticides, May 16, 2018) Northern Harvest Sea Farms, an ocean-based fish farm in New Brunswick, Canada, was appeared in court yesterday to answer legal charges stemming from the off-label use of an unnamed pesticide added to its operations to combat severe sea lice outbreaks. The company holds nine licenses for farmed Atlantic salmon cages on the Bay of Fundy, as well as for fish farms off the Newfoundland coast. Sea lice outbreaks are a common at over-crowded, ocean-based fish farms because such facilities afford the optimum conditions for rapidly reproducing and spreading lice. In response, some companies have turned to using illegal and off-label pesticide applications to stave off the problem, which causes huge farmed salmon kills. The company was issued a $12,000 fine that was challenged as inadequate by the Grand Manan Fishermen’s Association. Bonnie Morse, project manager for the association told Canadian Broadcasting Corporation (CBC) news, “I think any time there’s a fine that’s a deterrent to illegal activity, it should be an actual deterrent to the activity,” said Morse. “When you’re looking at $1.5 million worth of fish, their actions speak for themselves.” Maria Recchia, the executive director of the Fundy North Fishermen’s Association, questioned the allowance of fish […]

(Beyond Pesticides, May 15, 2018) According to a new report from the Center for Biological Diversity (CBD), hundreds of thousands of pounds of pesticides are sprayed on lands that are designated as refuges for wildlife and protected under U.S. law. Approximately 490,000 pounds of pesticides have been sprayed on crops grown in national wildlife refuges in 2016 alone. Pesticide use in these sensitive areas poses risks to pollinators, aquatic organisms, migratory birds, and other wildlife on refuges that were created to protect them. The report, No Refuge, released last week, analyzes pesticide use on national wildlife refuges using records obtained through a Freedom of Information Act request. The report finds that in 2016 more than 270,000 acres of refuge lands were sprayed with pesticides for agricultural purposes. Five national wildlife refuge systems are identified as most reliant on pesticides for agriculture: Klamath Basin National Wildlife Refuge Complex in California and Oregon, with 236,966 pounds of pesticides; Central Arkansas Refuges Complex in Arkansas, with 48,725 pounds of pesticides; West Tennessee Refuge Complex in Tennessee, with 22,044 pounds of pesticides; Tennessee National Wildlife Refuge Complex in Tennessee, with 16,615 pounds of pesticides; and, Chesapeake Marshlands National Wildlife Refuge Complex on the Eastern Shore of Maryland and Virginia, with […]

(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 7, 2018) Beyond Pesticides and The Organic Consumers Association (OCA) today responded to a federal judge’s ruling against Monsanto Co.’s motion to dismiss the groups’ lawsuit, filed in April, 2017. The lawsuit challenged Monsanto’s safety claim on its Roundup (glyphosate) products as misleading and fraudulent. Monsanto displays a claim on its Roundup product label that states that the chemicals in the product “targets an enzyme bound in plants but not in people or pets,” when, in fact, the chemical adversely affects beneficial bacteria essential to the gut biome and normal body functions. Jay Feldman, executive director of Beyond Pesticides, the lead plaintiff in the case, said: “In the face of EPA’s poor regulation of pesticides, misleading pesticide product labeling cannot be left unchecked. The court’s decision to allow our case to move forward, in denying Monsanto’s motion to dismiss, is critical to showing that the company is deceiving the public with a safety claim on its Roundup (glyphosate) label. Its advertising and labeling claim that Roundup ‘targets an enzyme found in plants but not in people or pets’ is false, given the devastating harm that glyphosate has on beneficial bacteria in the gut biome. The disruption of the […]

(Beyond Pesticides, May 6, 2018) The Washington State Department of Ecology (Ecology) temporarily denied a permit to spray Willapa Bay and Grays Harbor with the toxic neonicotinoid insecticide imidacloprid. Your comments helped achieve the temporary decision and comments are now needed again to make the denial permanent. The public comment period closes on May 14, 2018. Willapa Bay and Grays Harbor, with a number of unique ecosystems, and among the most pristine estuaries in the U.S., have been targeted with a plan to spray the toxic neonicotinoid insecticide imidacloprid to kill the native burrowing shrimp in beds of commercial Japanese oysters. This insecticide use will have deadly effects on keystone aquatic organisms. Based on a Supplemental Environmental Impact Statement (SEIS) and public input, Ecology temporarily denied the permit. Tell Ecology to restore the bays instead of spraying them! Ecology bases its decision on these factors: Too great an impact on the marine organisms that live in the sediments where the pesticide application is proposed. Too much uncertainty about the long-term impacts associated with this pesticide. Negative impacts on fish and birds caused by killing sources of food and disrupting the food web. Even at low concentrations, imidacloprid has significant impacts […]

(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 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 17, 2018) In a case that appalled the nation, the U.S. Justice Department finally last week secured an indictment against an applicator who illegally applied a fumigant at a U.S. Virgin Island resort, causing devastating and long-term health effects to a family on vacation. Terminex has already been fined and paid a multi-million dollar settlement with the poisoned family. Jose Rivera, 59, was indicted last Thursday by a federal grand jury for violating the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). According to the indictment, Mr. Rivera illegally applied fumigants containing methyl bromide in multiple residential locations in the U.S. Virgin Islands, including the condominium resort complex in St. John, where a family of four fell seriously ill in March 2015, announced Assistant Attorney General Jeffrey H. Wood of the Environment and Natural Resources Division and U.S. Attorney Gretchen C.F. Shappert for the District of the Virgin Islands.   The indictment alleges that Mr. Rivera knowingly applied restricted-use fumigants at the Sirenusa resort in St. John for the purpose of exterminating household pests on or about Oct. 20, 2014, and on or about March 18, 2015.  The defendant was also charged with applying the restricted-use pesticide in eight residential […]

(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 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 4, 2018) In late March, the Missouri Department of Agriculture hosted a public hearing to discuss a proposed emergency rule restricting the sale and use of the herbicides dicamba and 2,4-D – which are known for their ability to drift off-site and damage sensitive crops. The emergency rule was introduced to prevent off-label use of specific dicamba or 2,4-D products. Thus far, dicamba is responsible for damaging approximately 325,000 acres of soybeans in the state last year. The proposed rule will stop sales of the herbicides dicamba and 2,4-D between April 15 and October 1 in Missouri. The department’s goal is to prevent off-label pesticides from drifting onto neighboring property and damaging other crops. According to the department, if it chooses to pursue an emergency rule, it could become effective as soon as April 1, 2018, and expire 180 days later. The rule also requires registrants to provide a sales record by April 30 for each pesticide sold between October 1 and April 15. A proposed rule will be filed at the same time as an emergency rule to initiate the formal rulemaking process. The draft rule language reads as follows: Pesticides that meet the conditions of this section are […]

(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 21, 2018) According to a new study published this month in Environment Health, women with high levels of glyphosate in their bodies are more likely to have shorter pregnancies. Shorter pregnancies can lead to children with reduced learning and brain development. This is the first study to suggest that exposures to glyphosate can influence the long-term well-being of children. The study, Glyphosate exposure in pregnancy and shortened gestational length: a prospective Indiana birth cohort study, obtained both urine and drinking water samples from 71 women with pregnancies living in Central Indiana while they received routine prenatal care, and analysed the relationships of glyphosate levels in mother’s urine with fetal growth indicators and gestational length. The researchers found that more than 90 percent of pregnant women had detectable levels of glyphosate where higher glyphosate levels were significantly correlated with shortened gestational lengths, even though the drinking water samples had little to no detectable levels of glyphosate. Women living in rural areas were found to have higher glyphosate levels. The authors note their study is significant because it is the first U.S. study designed specifically to measure prenatal glyphosate exposure in pregnant women to determine its association with adverse fetal […]

(Beyond Pesticides, March 20, 2018) Regulations that separate ingredients in pesticide products as either “other/inert” or “active” have no scientific basis, according to a new review of the toxicity of formulated pesticide products published in the journal Frontiers in Public Health. Despite widespread awareness that “other” or “inert” pesticidal ingredients present toxicity concerns, only “active” ingredients undergo a full risk assessment, and pesticide products containing both active and inert ingredients are not tested in formulation before being sold to the public. Using glyphosate and neonicotinoid based products as examples, the study recommends sweeping changes to the way pesticide formulations are regulated in the Western world. Inert, or other ingredients –not disclosed on pesticide product labels, are often adjuvants that are added to a pesticide formulation to modify the effect of the active ingredient. However, they can also be sold separately and used in agriculture where pesticides are often “tank mixed” on site before application. Adjuvants take many forms, including surfactants, dyes, stabilizers, propellants, emulsifiers, solvents, antifoaming agents, and still other uses. Surfactants, likely the most common adjuvant, are added to a pesticide formulation in order slow the degradation time or improve the penetration of the active ingredient on a target […]

(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 […]
