(Beyond Pesticides<\/em>, April 28, 2023) A study published in Science of The Total Environment<\/em><\/a>\u00a0finds agricultural communities encounter chronic and measurable pesticide exposure regardless of seasonal pesticide applications. Several biomonitoring studies demonstrate people living adjacent to or within agricultural areas often experience elevated levels of\u00a0organophosphate (OP) insecticides<\/a>, even while not working directly with OPs. Six dialkyl phosphate (DAP) metabolites (breakdown products) of OPs persist in urine during the spraying and non-spraying seasons. Despite 75 percent of OPs metabolizing into one or more of the six DAPs and excreting within six to 24 hours after exposure, the consistent levels of DAPs in urine highlight continuous exposure beyond regular seasonal pesticide applications.<\/p>\n

OP 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\u00a0highly toxic<\/a> and, as this study shows, residues are\u00a0consistently present<\/a>\u00a0in human and animal urine, as well as blood, tissues, and milk. Considering\u00a090 percent<\/a>\u00a0of Americans have at least one pesticide compound in their body, primarily stemming from dietary exposure, including\u00a0food<\/a>\u00a0and\u00a0drinking water<\/a>, advocates maintain that current restrictions on their use must adequately detect and assess total chemical contaminants. The study notes, \u201cWe suggest that among agricultural communities that experience chronic exposure to nearby pesticide applications, OPs may persist in indoor and outdoor environments. The results of the current analysis provide additional evidence to suggest that residents of agricultural communities experience OP exposure even when [a] recent application has not occurred.\u201d<\/p>\n

Researchers gathered data from agricultural community members in the Central Valley of California to determine important factors associated with urinary DAPs levels among these high-exposure communities. The cohort included 80 children and adults who lived within 61 m (200 ft) of agricultural fields in the Central Valley of California in January (pesticide non-spraying season) and June (pesticide spraying season) 2019. The researchers collected one urine sample per participant during each visit to measure DAP metabolites. Additionally, researchers gathered supplementary data with in-person surveys to identify health, household, sociodemographic, pesticide exposure, and occupational risk factors. Using a data-driven, best-subsets regression approach, researchers identified key factors that influence urinary DAP levels.<\/p>\n

The results find those with seasonal employment, likely to be in agriculture, have higher DAPs concentration in urine than those who do not work seasonally. However, the subset regression identifies numerous individual- and household-level factors that influence total DAPs: \u201cthe number of years spent living at the current address, household use of chemical products to control mice\/rodents, and seasonal employment status.\u201d Among adults, those with education on pesticide exposure mitigation and age are significant factors associated with total DAPs in urine. Among adults only, the study identifies educational attainment (for total DAPs) and age category (for EDM) as significant factors.<\/p>\n

Numerous occupational hazards are associated with chemical exposure, especially among individuals with occupations that involve regular exposure to xenobiotic (foreign substance) compounds. The agricultural sector has a long-standing history of synthetic chemical use, which disproportionally affects\u00a0farmworkers<\/a>\u2018 health. Furthermore, farmworkers\u2019\u00a0children<\/a>\u00a0are at greater risk as their immune system response is immature and especially vulnerable to stressors from pesticide exposure. Synthetic chemicals in pesticides can accumulate in bodies, causing an amalgamation of health effects. These effects can range from heightened risks\u00a0of various cancers<\/a>\u00a0(e.g.,\u00a0prostate<\/a>, hepatic, liver, etc.) and\u00a0endocrine disruption<\/a>\u00a0to\u00a0mental health<\/a>\u00a0problems (e.g.,\u00a0depression<\/a>), respiratory illnesses (asthma<\/a>), and many other\u00a0pesticide-induced diseases<\/a>. However, pesticide exposure is ubiquitous and not confined to where it is applied. Pesticides and other toxic chemicals can enter homes from the workplace via clothes, shoes, and home-based personal protective equipment (PPE) and accumulate residues on laundry, on carpets, and in art\/house dust. Some cases demonstrate that levels of chemicals transported into the house can be high enough to cause an adverse health effect in a resident child or spouse. Although pesticide exposure through the skin or inhalation is most prevalent among individuals working around these toxic chemicals, the general population also experiences pesticide exposure through residues in food and water resources. Many of these chemical compounds remain in\u00a0soils<\/a>, water (solid<\/a>\u00a0and\u00a0liquid<\/a>), and the surrounding\u00a0air<\/a>\u00a0at levels\u00a0exceeding<\/a>\u00a0U.S. Environmental Protection Agency (EPA) standards. The increasing ubiquity of pesticides concerns public health advocates as current measures safeguarding against pesticide use do not adequately detect and assess total environmental chemical contaminants. Therefore, individuals will continuously encounter varying concentrations of pesticides and other toxic chemicals, adding to the body\u2019s burden of current-use chemicals.<\/p>\n

Organophosphate (OP) insecticide<\/a>\u00a0use is widespread, while the industry promotes the chemicals as having greater efficiency and lesser environmental persistence. However, OPs are a class of insecticides known to have adverse effects on the nervous system, having the same mode of action as nerve agents for chemical warfare. OPs originate from the same compounds as World War II\u00a0nerve agents<\/a>, adversely affecting the nervous system. Chemical exposure can cause\u00a0a buildup of acetylcholine (a chemical neurotransmitter responsible for brain and muscle function) and lead to<\/a>\u00a0acute impacts, such as uncontrolled, rapid twitching of some muscles, paralyzed breathing, convulsions, and, in extreme cases, death. The compromise of nerve impulse transmission can have broad systemic impacts on the function of multiple body systems. In addition to being highly toxic to terrestrial and aquatic organisms, human exposure to\u00a0organophosphates<\/a>\u00a0can induce endocrine disruption, reproductive dysfunction, fetal defects, neurotoxic damage, and kidney\/liver damage. Exposure can increase vulnerability to deadly diseases, including\u00a0COVID-19.<\/a>\u00a0Furthermore, OPs are one of the leading causes of\u00a0intentional poisoning<\/a>\u00a0globally, as pesticide toxicity makes them potentially lethal substances.<\/p>\n

Urinary OP biomarker levels did not vary, and the risk was the same throughout all seasons. OP metabolites are typically excreted in the urine within a 6- to 24-hour period, so the study concludes that participants who had detectable levels of urinary DAPs had a recent exposure to OPs, regardless of seasonal spraying. There are other more prominent sources of OP contamination. For instance, diet accounts for a considerable proportion of people\u2019s exposures to pesticides in the U.S.;\u00a02016 data from the United States Department of Agriculture (USDA) show<\/a>\u00a0that 47% of domestically produced foods and 49% of imported foods had detectable pesticide residues. A number of studies point to organics as protective as\u00a0studies confirm<\/a>\u00a0that urinary DAP levels reduce after a week-long shift to an organic diet;\u00a0a 2015 study<\/a>\u00a0that found that adults who consumed organic produce had lower urinary levels of organophosphate residues (as detected via levels of DAPs); and\u00a0another in 2015 that concluded<\/a>\u00a0that a switch to an organic diet reduced the body burden of pesticides in children, especially in low-income urban, marginalized, and agricultural communities. Considering this study finds urinary OP metabolites among children and household dust OP levels increase as residential distance to orchards decreases, the study identifies important factors that influence pesticide exposure among agricultural communities. Given proximity to applications, take-home exposure from occupational workers, and residual environmental exposures, a majority of pesticide exposure disproportionately burdens Hispanic\/Latino(a) communities, which contain most of the population in the study area. However, the study suggests future research establishes exposure routes that put agricultural communities, and others at risk.<\/p>\n

The study concludes, \u201cWe suggest that future research should explore more refined exposure assessment methods to evaluate unique routes of exposure (i.e., inhalation, ingestion, or dermal contact). These efforts will support strong epidemiologic research to identify health impacts of OPs. Findings may also support community education about effective and personalized exposure mitigation strategies for agricultural community members to promote environmental justice.\u201d<\/p>\n

Although most OP uses in the U.S. are now agricultural,\u00a0toxicity experts<\/a>\u00a0recommend banning all OPs for agricultural use. EPA and the World Health Organization (WHO) consider over\u00a040<\/a>\u00a0OPs that are moderately or highly hazardous to human health. EPA classifies as probable carcinogens some commonly used OPs like malathion, a popular mosquito control, and tetrachlorvinphos, a common flea and tick killer in pet collars and shampoos. States, including Hawaii, California, New York, and Maryland, had already adopted plans to phase out uses of the OP chlorpyrifos<\/a>, to different degrees, in agriculture following evidence of neurotoxic effects on children. EPA announced the\u00a0cancellation<\/a>\u00a0of all chlorpyrifos food production uses in the U.S., as chemical contamination among the general population remained considerable even after implementing residential use restrictions over two decades ago. However, even with the agency announcement of agricultural use cancellations, chlorpyrifos will still remain available for golf courses and as mosquito adulticide.<\/p>\n

The pesticide marketplaces still contain many chemicals that cause similar endocrine-disrupting, cancer-causing, neurotoxic health effects. Additionally, imported goods can still contain chemical residues as chlorpyrifos residues do not disappear immediately after end-use and will persist in our environment for quite some time.<\/p>\n

Therefore, policies should enforce stricter pesticide regulations and increase research on the long-term impacts of pesticide exposure. Beyond Pesticides tracks the most recent studies related to pesticide exposure through our\u00a0Pesticide Induced Diseases Database (PIDD)<\/a>. This database supports the clear need for strategic action to shift away from pesticide dependency. For more information on the many harms of pesticides on health, see PIDD pages on\u00a0body burdens<\/a>\u00a0(urine and other compartments<\/a>),\u00a0endocrine disruption<\/a>,\u00a0cancer<\/a>, and other diseases.

The founders, who established Beyond Pesticides (originally as National Coalition Against the Misuse of Pesticides) as a nonprofit membership organization in 1981, felt that without the existence of such an organized, national network, local, state and national pesticide policy would become, under chemical industry pressure, increasingly unresponsive to public health and environmental concerns. Beyond Pesticides believes that people must have a voice in decisions that affect them directly. We believe decisions should not be made for us by chemical companies or by decision-makers who either do not have all of the facts or refuse to consider them. Learn more about our work, read A Year in Review\u20142021, our accomplishments are your victories! Beyond Pesticides seeks to protect healthy air, water, land, and food for ourselves and future generations. By forging ties with governments, nonprofits, and people who rely on these natural resources, we reduce the need for unnecessary pesticide use and protect public health and the environment. Beyond Pesticides provides hands-on services to the public and supports local action by: identifying and interpreting hazards; and, designing safe pest management programs. With the information provided by Beyond Pesticides, people may not only be able to make informed choices and adopt practices that protect themselves and their families from unnecessary exposure to pesticides, but they will be able to effect changes on community-wide pest management decisions and policies that govern pesticide use, such as pesticide uses in parks, schools, for community insect control and along roadsides. Beyond Pesticides believes that people must have a voice in decisions which affect them directly.","sameAs":["https:\/\/www.beyondpesticides.org","https:\/\/www.facebook.com\/beyondpesticides\/","https:\/\/www.instagram.com\/beyondpesticides\/","https:\/\/www.linkedin.com\/company\/beyond-pesticides\/","https:\/\/x.com\/ByondPesticides","https:\/\/www.youtube.com\/user\/bpncamp\/"],"url":"https:\/\/beyondpesticides.org\/dailynewsblog\/author\/beyond-pesticides\/"}]}},"_links":{"self":[{"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/posts\/32814","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/comments?post=32814"}],"version-history":[{"count":4,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/posts\/32814\/revisions"}],"predecessor-version":[{"id":32831,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/posts\/32814\/revisions\/32831"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/media\/32816"}],"wp:attachment":[{"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/media?parent=32814"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/categories?post=32814"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/tags?post=32814"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
