(Beyond Pesticides, December 7, 2022) A recent study from Australian researchers has investigated pesticide use through an unusual lens — by quantifying the environmental footprints of pesticide use in 82 countries and territories (and eight regions), and then concluding that international trade drives significant pesticide use. The researchers identify the U.S., Brazil, and Spain as the biggest exporters of the “pesticide hazard load” associated with those environmental footprints, and China, the United Kingdom, and Germany as the top three importers. They lay responsibility for this hazard load at the feet of the unsustainable intensification of chemical-intensive agriculture (via synthetic pesticide and fertilizer use during the past 50 years), and ratcheting consumer demand for goods and services. Indeed, they conclude that the latter, in “developed” countries, is responsible for a substantial portion of the pesticide pollution in other countries. The study authors note that previous “efforts to quantify the environmental footprints of global production and consumption have covered a wide range of indicators, including greenhouse gas emissions, water scarcity, biodiversity, nitrogen pollution, acidification, land use, and others, but they have largely missed . . . represent[ing] the environmental pressures exerted by pesticide use.” The researchers set themselves the task of quantifying […]

(Beyond Pesticides, December 6, 2022) Persistent organic pollutants (POPs)—including banned pesticides—present a health risk to humpback whales (Megaptera novaeangliae), according to a study published in Environmental Pollution. Regarding female humpback whales, levels of POPs in blubber are higher in juveniles and subadults than in adults, primarily from the transference of contaminants from the mother to her calf.  Organochlorine compounds (OCs), such as organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs), are well-known persistent organic pollutants. The international Stockholm Convention treaty (signed by 152 countries, but not the U.S.) banned these primary pollutants of concern (UNEP, 2009) in 2001 (taking effect in 2004) because of their persistence, toxicity, and adverse effects on environmental and biological health. These pollutants have a global distribution, with evaporation and precipitation facilitating long-range atmospheric transport, deposition, and bioaccumulation of hazardous chemicals in the environment. However, these chemicals can remain in the environment for decades and interact with various current-use pesticides, including organophosphates, neonicotinoids, and pyrethroids. Although various studies demonstrate the volatile, toxic nature of POPs, much less research evaluates the impact POPs have on maternal offloading or transfer of contaminates to offspring and respective health consequences. The globe is currently going through the Holocene Extinction, Earth’s 6th mass extinction, with one […]

(Beyond Pesticides, December 5, 2022) A petition filed last week with the U.S. Fish and Wildlife Service (USFWS) urges increased protections for the West Indian manatee after dramatic declines in its population over recent years. In 2017, USFWS downgraded the classification of the manatee from endangered—a category that broadly protects against “take,” defined as “to harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect, or to attempt to engage in any such conduct”—to threatened, for which an “acceptable” level of “take” is allowed. Following the downlisting of the species, manatee populations have declined dramatically. Tell the U.S. Fish and Wildlife Service to upgrade the Florida manatee to endangered and require protection from chemical pollution. Tell your Congressional Representative to cosponsor H.R. 4946 and your Senators to introduce identical legislation. Tell Florida’s Fish and Wildlife Conservation Commission to protect manatees. Florida manatees, a subspecies of the West Indian manatee (Trichechus manatus), can live as long as 60 years, weigh up to 1,200 lbs, and have no natural predators. The biggest threat to these peaceful marine mammals is human activity. Humans harm manatees directly through boat strikes and encounters with fishing equipment, canal locks, and other flood control structures, but the largest threat […]

(Beyond Pesticides, December 2, 2022) The longest-running — four-decade — investigation comparing organic and conventional grain-cropping approaches in North America is reporting impressive results for organic. Recently announced in the Rodale Institute’s Farming Systems Trial — 40-Year Report are these outcomes: (1) organic systems achieve 3–6 times the profit of conventional production; (2) yields for the organic approach are competitive with those of conventional systems (after a five-year transition period); (3) organic yields during stressful drought periods are 40% higher than conventional yields; (4, 5, and 6) organic systems leach no toxic compounds into nearby waterways (unlike pesticide-intensive conventional farming), use 45% less energy than conventional, and emit 40% less carbon into the atmosphere. Beyond Pesticides reported in 2019 on similar results, from the institute’s 30-year project mark, which have been borne out by another three years of the trials. The current report builds on results from the FST that were shared in the RI’s 2020 white paper, Regenerative Organic Agriculture and Climate Change: A Down-to-Earth Solution to Global Warming,” which integrated the newest research data and offered action steps for consumers, policymakers, farmers, and others. That report asserted that a global switch to a regenerative food system could not […]

(Beyond Pesticides, December 1, 2022) The U.S. Environmental Protection Agency (EPA) must put measures in place to protect endangered species from the hazardous insecticide cyantraniliprole before September 2023. The requirements stems from a recent federal appeals court ruling that found EPA in violation of its statutory obligations under the Endangered Species Act (ESA). The agency originally lost its legal case on this chemical in 2017, but has since done nothing to fulfill the initial court order, necessitating further litigation by conservation groups. “It’s outrageous that the EPA is thumbing its nose at a federal court order even as cyantraniliprole wreaks havoc on our most endangered wildlife,” said Jonathan Evans, environmental health legal director at the Center for Biological Diversity. “The EPA has acknowledged that this pesticide is incredibly toxic to bees and other invertebrates, but the agency is so accustomed to putting the profits of the pesticide industry ahead of its duty to protect human health and our environment that for years it simply ignored a direct court order.” Cyantraniliprole is a systemic insecticide registered for use in 2014. It presents similar risks to pollinators and wildlife as other widely used systemics, such as the neonicotinoid class of chemicals. Its […]

(Beyond Pesticides, November, 30, 2022) A petition filed last week with the U.S. Fish and Wildlife Service (USFWS) urges increased protections for the West Indian manatee after dramatic declines in its population over the last several years. In 2017, the USFWS downgraded protections for the manatee, a move that was widely criticized by conservation groups as premature. That sentiment has become a reality, with nearly 2,000 manatees dying over the last two years from a range of preventable factors. West Indian manatees, a species of manatee that includes the Florida and Antillean Manatee subspecies, were first listed under the Endangered Species Act (ESA) in 1973, at a time when there were less than 1,000 individual animals in the United States. By 2017, the number of manatees had increased to over 6,000, leading then-Interior Secretary Ryan Zinke to downlist (downgrade) the animals from endangered to threatened under ESA. ESA works to protect species by listing them as either threatened or endangered. A species classified as endangered is in danger of extinction throughout all or a significant a portion of its range and a threatened classification means the species is likely to be endangered within the foreseeable future.  Endangered species are given […]

(Beyond Pesticides, November 29, 2022) Based on new international research adding weight to previous research on falling sperm counts, it is critical that environmental agencies address this and other problems related to endocrine disruption. The study by Levine et al. finds that the drop in sperm count—a drop of 51.6% from 1973 through 2018—is global and that the rate of decline is accelerating. Tell EPA and Congress that pesticide use cannot continue without findings of no endocrine disruption.  The documented (average) drop in sperm counts is approaching the level at which the ability to cause a pregnancy begins to plummet dramatically. The reduction in male fertility may have profound psychological and social impacts, including anxiety, low self-esteem, and depression. These psychological problems have health impacts of their own. Equally serious are connections of anxiety and depression with violent behavior and suicide. Compounding the problem is the fact that men are unlikely to seek fertility-related social support. The drop in sperm counts is just one example of endocrine disruption largely due to exposure to toxic chemicals. The endocrine system consists of a set of glands (thyroid, gonads, adrenal and pituitary) and the hormones they produce (thyroxine, estrogen, testosterone, and adrenaline), which […]

(Beyond Pesticides, November 27, 2022) On Tuesday, November 29 (at 1:00-2:30pmEST), two preeminent researchers will present their research and worldwide collaborative work to fully characterize the effects of the climate crisis and the viable solutions associated with land management. The Forum headliners are (i) Rachel Bezner Kerr, PhD, Cornell University professor just back from COP 27 [27th Conference of the Parties to the United Nations Framework Convention on Climate Change] and co-author of the definitive United Nations (UN) report on climate and food production and (ii) Andrew Smith, PhD, chief operating officer of the Rodale Institute and coauthor of several landmark reports on soil biology and carbon sequestration, including the just released Farming Systems Trial—40-Year Report. With livability of the planet on the brink, the speakers at the upcoming Forum make the case to immediately reverse the increase of greenhouse gases, carbon dioxide, nitrous oxide, and methane to stop the changes on the horizon that destroy life—from floods, fires, and associated climate-induced hazards to food production. The good news, according to the scientists, is that there are solutions available now in the agricultural and land management sectors that can reverse the threat if dramatic changes are made. Dr. Bezner Kerr, […]

(Beyond Pesticides, November 25, 2022) A study published in Chemosphere adds to the growing body of research demonstrating the endocrine (hormone) disrupting effects of glyphosate play in breast cancer development. Exposure to the herbicide glyphosate and other glyphosate-based herbicides (GBHs) at high concentrations mimics the estrogen-like cellular effects of 17β-estradiol (E2), altering binding activity to estrogen receptor α (ERα) sites, thus causing fundamental changes in breast cancer cell proliferation (abundance).  Glyphosate is the most commonly used active ingredient worldwide, appearing in many herbicide formulas, not just Bayer’s (formerly Monsanto) Roundup®. The use of this chemical has been increasing since the inception of crops genetically modified to tolerate glyphosate over two decades ago. The toxic herbicide readily contaminates the ecosystem with residues pervasive in food and water commodities. In addition to this study, literature proves time and time again that glyphosate has an association with cancer development, as well as human, biotic, and ecosystem harm. Therefore, advocates point to the need for national policies to reassess hazards associated with disease development and diagnosis upon exposure to chemical pollutants. The researchers note, “The results obtained in this study are of toxicological relevance since they indicate that glyphosate could be a potential endocrine disruptor in the mammalian system. Additionally, […]

(Beyond Pesticides, November 24, 2021) On Thanksgiving, thank you for being a part of Beyond Pesticides and sharing and contributing to the vision necessary to protect the web and the fragility of life. We believe that there is no time like Thanksgiving to think about how we can more effectively join together as families and communities across divisions and different points of view to find a common purpose in protecting the health of the environment and all that inhabit it. Unfortunately, a host of pesticides, genetically engineered materials, and others in conventional Thanksgiving foods impact human health and threaten the environment. With far too many adverse health and ecological effects associated with toxic chemicals, organic practices are viable solutions to mitigate pesticide contamination and subsequent exposure. Read on as we consider the range of challenges we must confront and the solutions that can bring us all together. Additionally, you can help Beyond Pesticides in educating and building a movement that will bring long-needed protection to humans, animals, and the entire environment by attending the third seminar on November 29 on Climate during the 2022 National Forum Series, Health, Biodiversity, and Climate: A Path for a Livable Future. The National Forum […]

(Beyond Pesticides, November 23, 2022) A new study throws into question the value of the pest management concept of setting action levels around pest infestations. In the course of watermelon production over a span of two years, pollination, not pest levels, was the key determining factor for yield. “These data advocate for a reprioritization of management, to conserve and protect wild bee pollination, which could be more critical than avoiding pest damage for ensuring high yields,” the study, published in Proceedings of the Royal Society B, indicates. Action levels are considered an important aspect of an integrated pest management (IPM) approach in agriculture, whereby a pest infestation reaches levels considered economically unacceptable, leading to a decision to engage in pest control. The concept of IPM however has been influenced by the chemical industry over the decades since its original definition and recent data indicates that it has failed to stop toxic pesticide use. The original intent of IPM was the adoption of preventive practices and utilization of nonchemical tools, placing pesticide use as a last resort when pest control is warranted. However, farms that self-identify as IPM operations use pesticides, sometimes as the first line of defense, while attempting to […]

(Beyond Pesticides, November 18, 2022) A new meta-analysis, from researchers at Mount Sinai Medical Center, Hebrew University of Jerusalem, and the University of Copenhagen, among others, finds that the drop in global sperm count is accelerating and the problem has become global. The study shows that sperm count (until this study measured largely in North America, Europe, and Australia) has dropped by 51.6% from 1973 through 2018, and that the rate of decline is gaining speed worldwide.  A primary culprit, among a plexus of factors, is widespread exposure to toxic chemicals, including pesticides, in the environment. Beyond the implications for individuals and families, this global decline in sperm counts has the potential for population-level impacts and, according to Dr. Shanna Swan, an expert environmental–reproductive epidemiologist, could mean that “in the coming decades, large swaths of the global population of men could be subfertile or infertile.” Beyond Pesticides has long highlighted the relationship between reproductive anomalies and toxic pesticides, particularly the role of endocrine-disrupting (ED) compounds. Most recently, we covered a meta-study on pesticides and fertility that “finds exposure associated with lower semen quality, DNA fragmentation, and chromosomal abnormalities.” The new study is covered in Environmental Health News (EHN). From 1972 […]

(Beyond Pesticides, November 17, 2022) A report published in Toxicology and Applied Pharmacology finds organophosphate (OP) insecticides and the coronavirus (SARS-CoV-2/Covid-19) illicit similar damage to the heart and co-occurring exposure to both can escalate cardiac (heart) injury. Previous research suggests OPs may increase the ability of SARS-CoV-2 to cause COVID-19, especially among vulnerable individuals with underlying medical conditions. OPs have a wide range of biological uses—from insecticides to flame retardants—that make these chemicals ubiquitous, significantly contributing to ecosystem contamination. These compounds have a global distribution, with evaporation and precipitation facilitating long-range atmospheric transport, deposition, and bioaccumulation of hazardous chemicals in the environment. OPs are highly toxic, originating from the same compounds as World War II nerve agents, and residues are consistently present in human and animal blood, urine, tissues, and milk. Moreover, OPs are one of the leading causes of poisoning globally. Therefore, it is vital to understand how OP exposure will impact human health in conjunction with other immunologically compromising diseases like COVID-19. Cardiovascular diseases are among the leading causes of death globally. Additionally, heart conditions are one leading cause of disability in the U.S., as research demonstrates environmental pollutant exposure can increase the risk of developing cardiovascular disease, including stroke, heart attack, heart failure, atrial fibrillation, and cardiac […]

(Beyond Pesticides, November 15, 2022) Spraying a flowering plant with synthetic fertilizers makes it less attractive to bumblebees, according to research published this month in PNAS Nexus.  “A big issue is thus—agrochemical application can distort floral cues and modify behaviour in pollinators like bees,” said study author Ellard Hunting, PhD, of the University of Bristol, UK. The findings underscore the limited understanding that proponents of chemical agriculture have for the complex processes that food production relies upon and reinforce calls for a broad scale transition to regenerative, organic farming practices. Scientists began with the knowledge that spray applications of various agrichemicals affect the visitation patterns of bumblebees and other pollinators through a range of different processes. Past research finds that notorious bee-killing neonicotinoid insecticides not only kill bees outright, but also result in a range of complex damage, including their ability to impede bees’ olfactory senses and adversely affect their vision and flying ability. Other chemicals like glyphosate weaken bees’ ability to distinguish between colors.   A growing area of research is investigating the ways in which pollinators use static electric fields surrounding flowers to find food sources. A 2013 study found that bumblebees use floral electrical fields to discriminate […]

(Beyond Pesticides, November 14, 2022) Glyphosate weed killers induce antibiotic resistance in deadly hospital-acquired bacteria, according to a new study published late last month in the journal Scientific Reports. This is the latest finding connecting commonly used herbicides to the rise of antibiotic resistant bacteria. To put this finding in context, antibiotic resistance is rising to dangerously high levels in all parts of the world, according to the World Health Organization. In the May 1, 2022, issue of the Bulletin of the World Health Organization, Samira Choudhury, PhD, et al. writes, “Often referred to as the silent pandemic, antimicrobial resistance claims the lives of over 700,000 people annually.” The authors continue, “A study suggests that if no actions are taken, antimicrobial resistance will cause 10 million deaths per year by 2050 and an economic impact of over 100 trillion United States dollars.” Tell EPA and Congress that antibiotic pesticides in agriculture, lawns, and landscapes must be eliminated. Use of antibiotics in animal agriculture has long been recognized as a contributor to widespread antibiotic resistance. More recently, recognition of the contribution of antibiotics in plant agriculture has led to pressure to eliminate agricultural uses of antibiotics used in medicine. However, two facts […]

(Beyond Pesticides, November 10, 2022) A meta-analysis by the University Alberta Hospital, Edmonton, AB, Canada, adds to the plethora of research linking prenatal (before birth/during pregnancy) pesticide exposure to carcinogenic (cancer) tumor development. The analysis, published in Human & Experimental Toxicology, finds parental exposure to pesticides during the preconception (before pregnancy) or pregnancy period increases the risk of Wilms’ tumor (a type of kidney cancer) occurrence among children. Already, studies find low levels of pesticide exposure during pregnancy or childhood cause adverse health effects, from metabolic disorders to mental and physical disabilities. Although medical advancements in disease survival are more prominent nowadays, childhood cancer remains the leading cause of death from disease among children. Furthermore, childhood cancer survivors can suffer from chronic or long-term health complications that may be life-threatening. Children are particularly vulnerable to the impacts of pesticide exposure as their developing bodies cannot adequately combat exposure effects. Moreover, a mother’s pesticide exposure can have a stronger association with cancer among a child than childhood exposure, and a newborn can still encounter pesticides. Therefore, it is essential to understand how pesticides impact the health and well-being of individuals during critical developmental periods, especially for latent diseases (e.g., cancers). The researchers performed a systematic review and meta-analysis on case-control studies […]

(Beyond Pesticides, November 3, 2022) In a fight against global warming, environmental groups Center for Biological Diversity (CBD) and Californians for Pesticide Reform (CPR) filed a formal legal petition in October 2022 urging the California Air Resources Board (CARB) to phase out the use of sulfuryl fluoride insecticides. Sulfuryl fluoride is a fluoride compound with various adverse health effects, including cancer, endocrine disruption, neurotoxicity (reduced IQ), and reproductive damage. CARB added sulfuryl fluoride to its list of “short-lived climate pollutants,” being the only state to do so since 1990. However, California does not include sulfuryl fluoride in the list of GHG emissions to reduce by 2020 as researchers were unaware the chemical was a greenhouse gas (GHG) until 2008. These termite and food use insecticides are 4,800 times more potent GHG than carbon dioxide at trapping carbon in the atmosphere. Furthermore, sulfuryl fluoride has high global warming potential and can remain in the atmosphere for more than 36 years. The case of sulfuryl fluoride presents an all too familiar pattern of widespread chemical use without proper knowledge of health and environmental effects before implementation and a failure to take regulatory action on known hazards after allowed in commerce. Therefore, CBD’s […]

(Beyond Pesticides, November 1, 2022) Honey bees exposed to a combination of multiple pesticides suffer a reduced lifespan and experience adverse changes to their gut microbiome, increasing susceptibility to pathogens and disease. This finding comes from a study published recently in Science of the Total Environment, which examines the interactions between the insecticides flupyradifurone and sulfoxaflor and the fungicide azoxystrobin on honey bee health. Both insecticides studied are considered substitutes for notorious bee-killing neonicotinoid insecticides, which move through the vascular system of the plant and contaminates its pollen, nectar, and guttation droplets. As declines in pollinator and insect life continue throughout the world, it is critical not only to understand and restrict widely used chemicals like neonicotinoids, but also the regrettable and deleterious substitutions the agrichemical industry has developed to replace them. As the present study reveals, pesticide risk assessments do not inadequately capture the range of harm that can result when pesticides are combined, necessitating a shift toward safer, alternative, and regenerative organic farming systems that do not use these dangerous chemicals. To better understand the impacts of combined pesticide exposure on honey bees, researchers employed three colonies located in Germany’s Martin Luther University that were inspected and free […]

(Beyond Pesticides, October 28, 2022) The Maine Congressional delegation — Senators Collins (R) and Angus King (I), and Representatives Chellie Pingree (D) and Jared Golden (D) — along with New Hampshire Senator Jeanne Shaheen (D), have introduced a bipartisan and bicameral bill — the Relief for Farmers Hit with PFAS Act — to help farmers who have been impacted by the scourge of PFAS (perfluoroalkyl and polyfluoroalkyl substances) chemicals. (The Senate version of the bill is available; the House version should be soon.) PFAS contamination has, as Beyond Pesticides documented in two Daily News Blog articles (here and here), become a huge, life-altering problem for agricultural producers in Maine and many other states. An early 2022 Safer States analysis of state-level legislation on PFAS demonstrated the extent of the problem via the response: more than 32 states have begun to act on the issue. Beyond Pesticides has covered the presence of PFAS in pesticides and pesticide containers, and in so-called “biosludge” or “biosolids”— realities that only reinforce the call for a rapid transition off of chemical-dependent agriculture and to regenerative organic agricultural practices that do not carry the enormous health and environmental risks of pesticide products and contaminated fertilizers. There […]

(Beyond Pesticides, October 27, 2022) A study published in Environment International adds to the growing body of research evaluating the association between neonicotinoid insecticides (neonics/NIs) and breast cancer. Past studies suggest neonics act as endocrine disruptors, affecting the development and regulation of estrogen hormones that promote breast cancer. However, this study is one of the few to evaluate the toxicological and molecular mechanisms involved in initiating breast cancer events. According to the Centers for Disease Control and Prevention (CDC), breast cancer is a disease that causes breast cells to grow out of control, with the type of breast cancer depending on the cells themselves. Most common forms of breast cancer have receptors on the cell surface that can increase cancer growth when activated by estrogen, progesterone, or too much of the protein called HER2. One in ten women will receive a breast cancer diagnosis, and genetics can only account for five to ten percent of cases. When a cancer cell lacks receptors for these molecules, G protein-coupled estrogen receptors (GPERs) are an essential biological target of estrogen and plays a role in hormone-dependent cancer development. GPERs regulate estrogen through non-genetic cellular pathways, forgoing attachment to standard molecular receptors, leading to triple-negative breast cancer (TNBC). Although past […]

(Beyond Pesticides, October 26, 2022) Inflammatory bowel disease (IBD) may be exacerbated by exposure to the herbicide propyzamide, used in both agriculture and on ornamental lawns and landscapes, according to research published in the journal Nature this month. As the rate of autoimmune diseases continues to increase rapidly in the U.S. and the world, it is critical for scientists to better understand the etiology behind these diseases and the environmental factors contributing to their development. Recent data show that the number of people living with Crohn’s disease and ulcerative colitis, common types of IBD, have risen annually by 3.4% and 2.8% respectively, between just the years 2001 to 2018. “As we learn more about the environmental factors that might contribute to disease, we can develop state- and national-level strategies to limit exposures,” said study coauthor Francisco Quintana, PhD. “Some chemicals don’t seem to be toxic when tested under basic conditions, but we do not yet know about the effect of chronic, low-level exposures over decades, or early-on in development.” Researchers did not begin their study investigating propyzamide. Initial intent focused on better understanding environmental factors that may be contributing to IBD. Using a range of different models, scientists cross-referenced data […]

(Beyond Pesticides, October 24, 2022) We need prevention of the causes of breast cancer, not just awareness. In 1985, Imperial Chemical Industries and the American Cancer Society declared October “Breast Cancer Awareness Month” as part of a campaign to promote mammograms for the early detection of breast cancer. Unfortunately, most of us are all too aware of breast cancer. Detection and treatment of cancers do not solve the problem. Tell EPA to evaluate and ban endocrine-disrupting pesticides, and make organic food production and land management the standard that legally establishes toxic pesticide use as “unreasonable.”  Next to skin cancer, breast cancer is the most common cancer among women, causing the second most cancer-related deaths in the United States. Genetic factors only play a minor role in breast cancer incidence, while exposure to external environmental factors such as pesticides plays a more notable role. For breast cancer, one in eight women will receive a diagnosis, and genetics can only account for five to ten percent of cases. Therefore, it is essential to understand how environmental exposure to chemicals like pesticides can drive breast cancer development. Several studies and reports, including U.S. Environmental Protection Agency (EPA) data, identify hundreds of chemicals as influential factors associated with breast cancer […]

(Beyond Pesticides, October 21, 2022) The U.S. Environmental Protection Agency (EPA) has just made two announcements, related to the quest for improved indoor air quality in buildings, that address mitigation of disease transmission — and that of COVID-19, in particular. Related to enactment of the National COVID-19 Preparedness Plan, EPA issued guidance on the efficacy of antimicrobial products used on surfaces, and registered a new pesticide product the agency says can be used against influenza and corona viruses (some of the latter cause COVID-19 infections). In addition, EPA opened a 60-day public comment period “to solicit information and recommendations from a broad array of individuals and organizations with knowledge and expertise relating to the built environment and health, indoor air quality, epidemiology, disease transmission, social sciences and other disciplines.” Beyond Pesticides cannot help but note the irony of an intention to improve air quality that EPA couples with registration of a new, airborne pesticide for indoor use. EPA expands on its RFI (Request for Information) related to indoor air quality, saying that it is “seeking input from a diverse array of stakeholders . . . about actions, strategies, tools and approaches that support ventilation, filtration and air cleaning improvements, and […]
