(Beyond Pesticides, February 10, 2021) Pollinator advocates are petitioning the U.S. Fish and Wildlife Service (USFWS) to list the American bumblebee (Bombus pensylvanicus) under the Endangered Species Act. The petitioners are the Bombus Pollinator Association of Law Students at Albany Law School and the Center for Biological Diversity. Like many other wild pollinators, the American bumblebee has undergone dramatic reductions in recent decades. According to petitioners, the last 20 years saw an 89% decline in the pollinator’s population. Declines of the American bumblebee have occurred throughout its range, which encompasses 47 of the lower 48 states. However, there are also particularly hard hit regions. In New York, for instance, the pollinators have experienced a stunning 99% decline in relative abundance. Midwestern populations are also severely affected. Losses have followed in lock step with declines in the rusty patched bumblebee, which was listed as endangered in 2017. While the rusty patched has lost 90% of its midwestern range, the American bumblebee has experienced 83% declines. The petitioners note that the American bumblebee declined across a larger land area, and in several states where it was once the most populous pollinator. The causes behind these catastrophic declines are familiar to many pollinator […]

(Beyond Pesticides, February 8, 2021) Immediately following his inauguration, President Biden issued an Executive Order (EO) directing the heads of all executive departments and agencies to produce recommendations for improving and modernizing regulatory review, with a goal of promoting public health and safety, economic growth, social welfare, racial justice, environmental stewardship, human dignity, equity, and the interests of future generations. This Executive Order, if effective, will  reverse the historical trend of status-quo regulatory reviews required by the White House Office of Management and Budget (OMB) that typically support vested economic interests of polluters (e.g., petroleum-based pesticide and fertilizer manufacturers). Instead, the President’s EO, Modernizing Regulatory Review, sets the stage for the adoption of agency policy across government to seriously and with urgency confront the climate crisis, biodiversity collapse, and disproportionate harm to people of color communities (environmental racism). Key agencies that can have a systemic effect in meeting these existential challenges are the Environmental Protection Agency (EPA), Department of Interior (DOI), Department of Agriculture (USDA), and Department of Labor/Occupational Safety and Health Administration (DOL/OSHA). But the EO will remain words on a page unless we all across the country exercise our voice and advocate for the changes necessary to end […]

(Beyond Pesticides, February 5, 2021) The American public has witnessed, in the barely launched tenure of President Joe Biden, a surge of Executive Orders (EOs). Based on the first flurry of orders, much of the Biden “reset” appears gauged to beat back Trump policies that worsened an already inadequate regulatory system, and to reconfigure federal operations and regulations so as to address and solve the biggest threats (beyond COVID) the country faces. Among the high-profile EOs already issued are three that stand out. One recalibrates the operations of the OMB (Office of Management and Budget) to forward health, racial equity, and environmental stewardship. A second and third seek, respectively, to restore scientific integrity and elevate the role of science across the federal government, and to tackle comprehensively the climate crisis with a “whole of government” approach. Beyond Pesticides welcomes these early efforts, and maintains that vigilance and robust advocacy will be necessary to achieve needed paradigmatic change across federal agencies, which exist to protect and support the American people. EOs are tools the President can wield to manage directly some operations of the federal government. They are seen as muscular and immediate means through which to change course, particularly in […]

(Beyond Pesticides, February 4, 2021) A review published in Food and Chemical Toxicology suggests organophosphorus pesticides (OPs) may increase the ability of SARS-CoV-2 to cause COVID-19, especially among vulnerable individuals with underlying medical conditions. Organophosphorus pesticides have a wide range of biological uses that makes these chemicals ubiquitous, significantly contaminating both terrestrial (land) and aquatic (water) environments. However, OPs are highly toxic, originating from the same compounds as World War II nerve agents. Moreover, OPs are one of the leading causes of poisoning globally. Therefore, it is vital to understand how OPs exposure will impact human health in conjunction with other immunologically compromising diseases like COVID-19. Considering COVID-19 and OP exposure act similarly on the respiratory system, exacerbating adverse inflammatory responses, reviews like these highlight the significance of evaluating synergism between diseases and toxic chemicals to safeguard human health. Researchers in the study note, “To curb SARS-CoV-2 infection, a healthy immune system is obligatory despite potent vaccine to alleviate morbidities in patients. But unintentional exposure to OP compounds from several sources can rupture the antiviral defense against SARS-CoV-2. Moreover, respiratory ailments may also be fueled by OP compounds. Hence, SARS-CoV-2 mediated morbidities and fatalities could be backed by unintentional exposure to OPs in […]

(Beyond Pesticides, February 2, 2021) The U.S. Environmental Protection Agency (EPA) will evaluate the effect of the neonicotinoid insecticide imidacloprid on endangered species, after an agreement was reached between the agency and the Natural Resources Defense Council (NRDC). Imidacloprid is one of the most commonly used insecticides in the world today and, like other neonicotinoids in its chemical class, has been linked to a range of adverse impacts on wildlife and their habitat. While the agreement to the assess effects on endangered species is important, advocates note that EPA should already have conducted this review, and further, that imidacloprid and other neonicotinoids should already be banned. NRDC’s successful lawsuit follows a separate legal challenge by the Center for Food Safety, Beyond Pesticides, beekeepers, and other environmental organizations which was settled in 2019. The judge in that case, focused on the neonicotinoids clothianidin and thiamethoxam, did not order EPA to consult with the U.S. Fish and Wildlife Service (FWS) and National Marine Fisheries Service (NMFS) (which is required when registering a pesticide in order to mitigate risks to endangered species). Instead, she directed the parties, including the plaintiffs, defendant EPA, and intervenor Bayer CropScience (the manufacturer of neonicotinoids), to move forward […]

(Beyond Pesticides, January 29, 2021) More oversight is needed to ensure farmworkers are protected from toxic pesticides, according to a report published this month by the U.S. Government Accountability Office (GAO) (the federal agency that provides auditing, evaluation, and investigative services for Congress). Revisions to the Worker Protection Standards (WPS) governing farmworker safety were updated by the Obama administration in 2015, but GAO identified a number of shortfalls in EPA’s administration of the changes. GAO focused its review on the implementation of the ‘designated representative’ provision, which grants farmworkers the ability to task an individual they designate to request information on toxic pesticides from their employers. Providing farmworkers with a designated representative allows for the access of pesticide application and hazard information, so that they may take proper precautions or seek medical care. A farmworker may use this provision when they are no longer near the farm they worked on, or if there are language barriers. Without this provision, the information farmworkers receive would be at the whim of employers, and past incidents show that lack of information can lead to hazardous, abusive conditions for workers. EPA officials, state officials, and stakeholders told GAO there was no evidence of such […]

(Beyond Pesticides, January 27, 2021) Lowest ever recorded! That’s the result of a yearly winter monarch count along the California coast, overseen each year by the conservation group Xerces Society. In 2020, citizen scientists counted only 2,000 butterflies. The findings indicate that many on the planet today are likely to experience, within their lifetimes, a world where western monarchs are extinct—unless the federal government acts now. Western monarchs migrate from the Pacific Northwest to overwintering grounds along the California coast, where they remain in relatively stationary clusters that are easy to count.  In the 1980s, roughly 10 million monarchs overwintered along the coast. By the 1990s, that number fell into the low single digits, roughly 1.2 million. Five years ago counts were at roughly 300,000. By 2019, numbers crashed below 30,000. This year’s count saw no monarchs at iconic overwintering sites like Pacific Grove. Other locations, like Pismo State Beach Monarch Butterfly Grove and National Bridges State Park saw only a few hundred. “These sites normally host thousands of butterflies, and their absence this year was heartbreaking for volunteers and visitors flocking to these locales hoping to catch a glimpse of the awe-inspiring clusters of monarch butterflies,” said Sarina Jepsen, […]

(Beyond Pesticides. January 25, 2021) First registered in 1970 and voluntarily cancelled in 2010, aldicarb (Temik™) was being manufactured in Bhopal, India in 1984 when a leak of a precursor—methyl isocyanate (MIC)—spread over the city, ultimately killing more than 25,000 people and leaving more than 120,000 people who still suffer from severe health problems as a result of their exposure. In 1989, Union Carbide Corporation—the manufacturer of aldicarb at the time—paid $470 million (equivalent to $860 million in 2019) to settle litigation stemming from the disaster. Aldicarb has been allowed by the outgoing Trump EPA for use on oranges. >>Tell EPA to Reverse Approval of Highly Toxic Insecticide Aldicarb! No pesticide epitomizes the “cradle-to-grave” dangers of pesticides better than aldicarb. The disaster in Bhopal was followed by others, including a leak in Institute, WV in 1985 that injured at least 135 people and a 2008 explosion in Institute, WV that killed two and injured at least eight. In use, it has been implicated in poisoning of workers and their children, poisoning deer and other game consuming contaminated seeds, and notably, poisoning food grown in soil treated with the chemical. The effects don’t stop there—aldicarb is also notorious for contaminating groundwater. […]

(Beyond Pesticides, January 21, 2021) A new Swedish study in Environmental Health Perspectives demonstrates individuals with genetically weakened skin barrier protection experience higher rates of toxic chemicals (i.e., pesticides) absorption through the skin. Studies provide evidence that filaggrin genetic mutations can exacerbate the impacts of chemicals upon dermal (skin) exposure, causing various skin diseases like dermatitis and other chemical-related effects like asthma and cancer. Filaggrin is a protein that is critical to skin cell structure or epidermal homeostasis. Just as excessive exposure to UV light can cause skin discoloration and cancer, excessive dermal contact with these toxic chemicals can cause a range of adverse reactions, including dermatitis, allergic sensitization, and cancer. Dermal exposure is the most common pesticide exposure routes, compromising 95 percent of all pesticide exposure incidents. Furthermore, many pesticides contain chemicals that act as sensitizers (allergens). Therefore, it is essential to mitigate direct skin contact with these toxic chemicals and enforce proper application protocol. Dermal chemical exposure is an increasing concern for occupational (work-related) health. Likewise, people experience dermal exposure to chemicals from everyday products like cleaning supplies, personal care products, agricultural chemicals, fabrics, non-stick cookware, and general airborne pollution. Furthermore, skin disease risks can increase among those with less protection from chemical exposure due to genetics. The study’s […]

(Beyond Pesticides, January 18, 2021) We honor Martin Luther King, Jr. today on Martin Luther King Day—a day of national service with volunteer opportunities across the nation. During this day of reflection, consider reading Dr. King’s “I Have a Dream Speech” or listening to it here. At Beyond Pesticides, our vision and work aligns with the vision Dr. King expressed—“Injustice anywhere is a threat to justice everywhere.” To that end, we seek to eliminate disproportionate risk, with elevated toxic hazards to people of color communities, with higher rates of pesticide-induced diseases among those who live in fenceline communities where chemicals are produced, among farmworkers who harvest the nation’s food, and among landscapers who manage our parks and children’s playing fields. We seek to transform national laws that allow risks under risk assessments that institutionalize environmental racism by allowing for this disproportionate risk. We seek to eliminate toxic pesticides production and use through the adoption of organic land management. To that end, we work with communities across the country to transition their land management to organic practices and we advance organic standards under the Organic Foods Production Act that have integrity and are fully enforced. Eliminating Toxic Pesticides with Organic Transformation […]

(Beyond Pesticides, December 24, 2020) We at Beyond Pesticides wish our members, supporters, and collaborators all the best for the holiday season and new year. We look forward to working with you in the new year to meet the serious environmental and public health challenges with truly organic solutions. Our accomplishments are your victories. We are seeing the outcomes in communities across the country—the adoption of organic land management policies and practices that eliminate toxic pesticides, protect children, pets, and families, and protect the local ecology. With your support of Beyond Pesticides, we strive to reverse the destructive environmental and public health path that we’re on and advance the adoption of organic practices and policies that respect life. Meeting the Challenges Ahead Beyond Pesticides is working toward the societal transition to practices and policies that eliminate toxic pesticide use. This work intersects with daily decisions made in households, school districts, and municipal and state governments, as well as at the federal level, on crucial issues relating to the health of children, families, and workers, the climate crisis, and biodiversity. Our work helps to inform practices and policies that go to the core of public health protection and the sustainability of […]

(Beyond Pesticides, December 17, 2020) The U.S. Environmental Protection Agency (EPA) is contemplating the reapproval of toxic, widely banned insecticide aldicarb for use on citrus fruits in Texas and Florida. A vast amount of scientific evidence reports a dramatic decline in insect population (i.e., the insect apocalypse), like pollinators and other beneficial biotas, from environmental pollution sources like pesticides. Therefore, it is important to assess regulatory decisions that can potentially jeopardize the protection of these species and, consequently, human health. Nathan Donley, PhD, a senior scientist at the Center for Biological Diversity (CBD), states, “The fact that U.S. regulators would even consider expanding use of this dangerous, widely banned pesticide is a stunning indictment of our broken regulatory system. This application vividly reaffirms why the pesticide industry considers us the dumping ground for the world’s worst pollutants. We’ll be watching closely to see whether the Biden administration steps up and puts public health before pesticide company profits.” Aldicarb is a highly toxic, systemic carbamate insecticide, with initial production beginning in 1965. The chemical is a fast-acting cholinesterase inhibitor that permanently binds to the active site of an essential enzyme for normal nerve impulse transmission, acetylcholinesterase (AChE), deactivating the enzyme. In […]

(Beyond Pesticides, December 14, 2020) As the President-elect chooses the leadership in his administration, it is critical that we in the affected communities establish our expectations of what is needed from agencies to address critical issues of the day. While we may feel that different choices of personnel could have been made, ultimately we are looking forward to advancing programs across all agencies that represent meaningful and foundational changes to our social, economic, and environmental norms. As we focus on the appointment of a Secretary of Agriculture, issues of foundational change come into sharp focus, relating to sustainable land management, distribution of resources and access to land, food security, protection of human and ecosystem health, and climate. It is normal, therefore, to look at any individual appointee’s past performance and positions as a measure of future decisions or policies that may be advanced. Ultimately, though, it is the administration that sets the tone, establishes a framework, and forges the direction of the government’s programs and policies. President-elect Biden has talked about a framework for policy to which we can and must hold all officials in the administration accountable across all agencies. These key elements of the framework intersect with the […]

(Beyond Pesticides, December 9, 2020) For consumers, the holiday season is full of complicated choices, including the conundrum of how to find the perfect Christmas tree. The most important part of selecting a tree is not its size and shape, but rather finding one that will pose the least risk to the health of your family, pets, and the environment. Thus, the safest holiday choice for you, and yours, is purchasing an organic tree as opposed to one that is artificial or grown using harsh chemical methods. However, the organic tree industry is still fairly novel, therefore following these helpful tips can ensure you purchase a beautiful organic tree and dispose of it in a responsible way to begin the New Year. Why Buy Organic? Christmas is one of the most celebrated holidays in the United States, with Christmas trees accompanying the celebration of the holiday season. On average, Americans purchase 25 to 30 million Christmas trees annually, with 2020 showing an almost 30 percent increase in sales. However, organic Christmas trees, which follow the same U.S. Department of Agriculture (USDA) organic standards as agricultural crops, make up only 1% of all Christmas tree purchases. Fortunately, public awareness regarding the need for more ecologically friendly, organic products is […]

(Beyond Pesticides, December 7, 2020) The Trump Environmental Protection Agency (EPA) reversed in four years much of the progress made by EPA in decades, and that push continues. The Biden EPA needs to advance a new vision. Tell President-elect Biden to adopt a new direction for pesticide regulation. Challenge so-called “benefits” of pesticides. The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) requires EPA to weigh risks against benefits when registering pesticides. Claimed “benefits” for toxic pesticides need to be judged in comparison to organic production, which is able to produce all types of food and feed. The Organic Trade Association reports that organic sales now exceed $55 billion per year, and the U.S. Department of Agriculture (USDA) finds that organic producers in the U.S. produced $9.9 billion worth of organic food on 5.5 million acres in 2019. EPA assumes benefits of pesticides, rather than measuring them, and does not take into account the development of resistance. The cost-competitive success of organic food production and nonagricultural land management practices make the case that toxic pesticides lack benefits. Protect pollinators. Agriculture relies on insect pollinators to facilitate fertilization and maintain annual crop yield. Globally, the production of crops dependent on pollinators is worth […]

(Beyond Pesticides, December 3, 2020) As the Trump administration winds down, it appears that it will continue to push through decisions that build on its formidable record of weakening environmental and public health protection. Ignoring documented threats to pollinators, the U.S. Environmental Protection Agency (EPA) could finalize its interim approval for flonicamid, a bee-toxic pesticide. Separately, EPA may reapprove the disinfectant ethylene oxide (EtO), despite concerns over carcinogenicity. NYU Law is tracking these and other last-minute federal environmental decisions on its webpage Midnight Watch. EPA proposed an interim reregistration decision for flonicamid in September 2020. California Attorney General Xavier Becerra has been highly and publicly critical of the agency’s approach on this chemical. In a public comment, Becerra wrote that EPA did not collect data from required follow-up studies regarding the impact of flonicamid on pollinators. EPA’s own risk assessment states that a “full assessment of pollinator risk cannot be conducted until data are available.” AG Becerra stated, “The Trump Administration’s EPA is failing at one of its most basic jobs by plowing ahead with the registration process for flonicamid before receiving additional data on its impact to pollinators like bees.” He continued, “California relies on pollination from bees for agriculture, a driving force of our state’s economy. We cannot ignore the […]

(Beyond Pesticides, November 30, 2020) The “environment” is central to President-elect Biden’s priorities: climate change, COVID-19, and the next pandemic, racial equity, and economic recovery. The new administration should include an EPA administrator who understands the relationships among these and other environmental issues and has a clear vision of the changes needed to dramatically change our course, currently heading for ecological destruction. Tell President-elect Biden to appoint an EPA Administrator who is an environmentalist with broad environmental credentials and a vision that embraces a dramatic transition away from hazardous chemicals and polluting practices at this perilous time. Let’s start with what the past four years has taught us about who we do NOT want as EPA Administrator. We do not want an industry lobbyist, someone whose work has been funded with industry money, who has represented industry in litigation or as a lobbyist, who has attacked environmentalists, or has never read Silent Spring. Such a person is not qualified to provide the leadership needed to address priority issues and understand the interconnections necessary to address the crises associated with climate, health, and biodiversity decline. On the other hand, a strong candidate will support holistic thinking, with an understanding of interrelationships in […]

(Beyond Pesticides, November 16, 2020) Since the U.S. Department of Agriculture (USDA) sits at the nexus of complex and systemic problems that need urgent attention—pesticide-dependent genetically engineered crops, the integrity of certified organic agriculture, and the climate crisis—the choice of the agency’s head is critical to meeting the challenges necessary to sustaining life. USDA has long been a big promoter of chemical-intensive agriculture. With President-elect Joe Biden committed to priorities of addressing health care, systemic racism, and climate change, the time is now for USDA to change the way it does business. We need an organic advocate in the Secretary of Agriculture, who must be committed to transitioning chemical-intensive agriculture to organic practices—thereby eliminating petroleum-based pesticides and synthetic fertilizers, sequestering atmospheric carbon, protecting farmworker and farmer health, delivering a safe food supply, and ensuring clean air, water, and healthy terrestrial and aquatic ecosystems. Tell President-elect Biden to appoint an organic leader as USDA Secretary. The purview of USDA is far-ranging—from SNAP (food stamps) to agricultural support programs to research to inspections and other regulations. And the National Organic Program. Research includes programs promoting pesticides and genetically engineered crops. USDA’s history with President-elect Biden’s priority issues has not been good historically. […]

(Beyond Pesticides, November 11, 2020) Neonicotinoid insecticides inhibit honey bee sleep cycles, leading to stress and population declines, according to research from Vanderbilt University, published in Scientific Reports. Although there is already ample evidence of the dangers these systemic insecticides pose to pollinators – as evidenced by recent bans in the European Union and Canada – this new line of investigation add further detail to the ongoing crisis in the pollinator world. “I was thinking about honey bee disappearances and it clicked—if pesticides are killing bees indirectly but we don’t know exactly how, maybe it’s because they’re getting physically lost,” said study coauthor Michael Tackenberg, PhD.  Scientists conducted the experiment using honey bees located on Vanderbilt’s campus, which does not use neonicotinoid insecticides. After returning from pollen collection, forager bees were captured at their hive entrance and moved into monitoring tubes, which were subsequently transferred to the lab. In the lab, scientists were able to control light and dark cycles, and exposed bees to levels neonicotinoids they would likely experience if foraging on contaminated flowers. Foraging bees were first exposed to light/dark at 12/12 cycles, followed by four days of complete darkness, at which time some bees were provided neonics, […]

(Beyond Pesticides, October 28, 2020) This month the U.S. Environmental Protection Agency (EPA) finalized decisions allowing continued use of a range of highly toxic pesticides, including the herbicide paraquat, and the synthetic pyrethroid class of insecticides. The move has been met with stinging criticism from the health and environmental community, but the decisions come as no surprise. Continued allowance of hazardous pesticides is a result of a weak law, lax regulations, and an administration that has consistently refused to follow even deficient protections. “The EPA’s pesticide office has sunk to a despicable new low in allowing farmworkers, small children and the environment to be sacrificial pawns in the profit schemes of its friends in the pesticide industry,” said Nathan Donley, PhD, senior scientist at Center for Biological Diversity. “In rushing to reapprove these deadly chemicals, it’s ignored its own scientists and independent researchers, refused to protect human health and the environment, and shown itself to be the panting lapdog of a morally bankrupt industry.” EPA reregistered paraquat despite overwhelming evidence that the chemical cannot be used without ‘unreasonable adverse effects on the environment’ — the lackluster standard in federal pesticide law to which the agency is required to regulate a […]

(Beyond Pesticides, October 27, 2020) The insecticide fipronil is more toxic to aquatic insects than previously thought, often present in U.S. waterways, and can trigger trophic cascades that disrupt entire aquatic ecosystems, finds new research published by the U.S. Geological  Survey (USGS). The data have important implications for waterways throughout the country, but particularly in the Southeast U.S. where the chemical was found at hazardous levels in over half of sampled steams. Despite the high quality of the findings by a U.S. government agency, pesticide regulators at the U.S. Environmental Protection Agency (EPA) do not adequately consider ecosystem-level effects when determining whether to register a pesticide. As a result, without public pressure on the agency, it is unlikely it will follow the science and take the action necessary to rein in use and safeguard the environment. Fipronil is a systemic pesticide that can travel through plant tissues and be expressed in its pollen, nectar, and dew droplets. Due to its systemic properties and similar toxicity profile, it is often targeted for restriction alongside the notorious neonicotinoid class of insecticides. Although fipronil is equally concerning, there is less data on the range of harm the chemical may cause. To better understand […]

(Beyond Pesticides, October 22, 2020) Prolonged dermal (skin) exposure to hazardous disinfectants, via handling and/or residue on surfaces, can induce the risk of adverse skin reactions (i.e., inflammation, burns, necrosis), according to a novel review analysis published in Clinics in Dermatology. Researchers of the review, “Dermatologic reactions to disinfectant use during the COVID-19 pandemic,” examine skin reactions associated with dermal exposure to various disinfectants approved for use against COVID-19 by the European Chemical Agency (ECA) and the U.S. Environmental Protection Agency (EPA). The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) classifies disinfectants as pesticides, so it is up to the states to delegate training, registration, and enforcement. Many states enforce pesticide training that allows professional applicators to learn how to handle, apply, and store pesticides properly. However, many of these same states do not have professional training for disinfectant use, especially wide-scale applications. Consequently, disinfectant applications are now more pervasive than ever, especially as school reopenings ensues. Considering failure to “Comply with Labeling and Permit Conditions” was the most common pesticide use violation of 2018, according to the California Department of Pesticide Regulations (DPR), advocates are urging global leaders to recognize the potential impacts that frivolous disinfectant use can have on […]

(Beyond Pesticides, October 15, 2020) A review of scientific literature on the correlation between respiratory diseases and pesticides exposure—published in the journal Annals of Agricultural and Environmental Medicine (AAEM), “Influence of pesticides on respiratory pathology—a literature review”—finds that exposure to pesticides increases incidents of respiratory pathologies (i.e., asthma, lung cancer, and chronic obstructive pulmonary disease [COPD]—or chronic bronchitis). The review by researchers at the Iuliu Hatieganu’ University of Medicine and Pharmacy Cluj-Napoca, Cluj-Napoca, Romania, looks at how pesticide exposure adversely propagates and reinforces respiratory diseases in humans. This review highlights the significance of evaluating how pesticide exposure impacts respiratory function, especially since contact with pesticides can happen at any point in the production, transportation preparation, or application treatment process. Researchers in the study note, “Knowing and recognizing these respiratory health problems of farmers and their families, and also of [pesticide] manipulators/retailers, are essential for early diagnosis, appropriate treatment, and preventive measures.” This study results are critically important at a time when exposure to respiratory toxicants increases vulnerability to Covid-19, which attacks the respiratory system, among other organic systems. The respiratory system is essential to human survival, regulating gas exchange (oxygen-carbon dioxide) in the body to balance acid and base tissue cells for normal […]
