(Beyond Pesticides, July 16, 2024) Yet another study in the August 2024 journal Ecotoxicology and Environmental Safety has found that exposure to organophosphorus pesticides (OPPs) is correlated with increased suicidal thoughts in some people. This study is just the latest in a long line of studies from around the world that have linked pesticide exposure to mental health conditions, including sleep disorders, depression, and suicidal ideation (SI). As the rate of suicide increased by 30% between 2000 and 2020, there is an urgent public health need to investigate and address all potential contributing factors. A 2019 study, covered in Daily News, found that teens and adolescents living in agricultural areas and exposed to organophosphate (OP) insecticides are at higher risk of depression, In July and January this year, other studies link farmer psychiatric episodes to pesticide exposure, adding to the body of science. Exposure to household pesticides is also linked to depression in a 2020 study.  Study and Methodology The study entitled “Association between exposure to organophosphorus pesticide and suicidal ideation among U.S. adults: A population-based study,” analyzes information on the mental and physical health of over 5,000 individuals aged 20 and up in the United States. The study aims […]

(Beyond Pesticides, July 2, 2024) Men’s Mental Health Awareness Month, which took place last month, evokes concern about the growing body of science linking pesticide exposure to neurological effects linked to depression. Recent studies reveal elevated rates of psychiatric disorders, including suicide, among farmers, with problems more common for males. Through systematic reviews, meta-analyses, surveys and interviews, and blood sampling, these three studies add to the growing body of science linking pesticide exposure to neurological impacts. First, in the Journal of Agromedicine, researchers from Greece and the United Kingdom review eight studies and find a significant positive association between pesticide poisoning and depression in agricultural populations.1 Second, a study in Toxicology shows a link between depression in Brazilian farmers and pesticide exposure, most notably with glyphosate usage.2 Third, the latest study in Environmental Toxicology and Pharmacology focuses on work by researchers from Spain in identifying farmers exposed to chlorpyrifos, mancozeb, and malathion that have higher rates of depressive symptoms and suicide attempts.3 Through a meta-analysis of published research, the authors of the Agromedicine journal article identify pesticide poisoning as a risk factor of depression. With depression affecting more than 264 million individuals worldwide, this is a field of interest with […]

(Beyond Pesticides, May 17, 2024) Massachusetts Governor Maura Healey (D) proclaimed May 12 -18, 2024 as Multiple Chemical Sensitivity Awareness Week, first established in 1998 in numerous states across the U.S. Multiple Chemical Sensitivity (MCS)—also called chemical intolerance or Toxicant-Induced Loss of Tolerance (TILT), is characterized by disorders in one or more body systems, including respiratory, gastrointestinal, musculoskeletal, and neurological processes. It is thought to be caused by adverse reactions to environmental chemicals and/or biological substances such as mold. Affected individuals suffer fatigue, rashes, muscle and joint pains, memory loss, and other symptoms. The Massachusetts proclamation encourages “residents of the commonwealth to take cognizance” of the event and recognize the distress of their fellow citizens who suffer from MCS. May 12 is also known as International May 12th Awareness Day, an observance started in 2006 in the United Kingdom to educate the public about many diseases associated with sensitivity to chemicals, including MCS, fibromyalgia, and Gulf War Syndrome. While some scientists have considered MCS a psychological or psychosomatic problem, there is increasing support for the reality of MCS as a physical disease distinct from mental or emotional disorders. Yet there are no medical tests that can reliably confirm a diagnosis, […]

(Beyond Pesticides, January 17, 2024) Science continues to find a link between mental health and occupational (work-related) chemical exposure, with a study published in Toxicology finding an increased risk of depression among farmers exposed to pesticides. Conventional, chemical-intensive farming is a profession notorious for higher-than-average pesticide exposure occurrences, thus explaining why the study concludes that individuals within this occupation can suffer from chemically induced oxidative stress, inflammation, and lower education-based cognition that exacerbate depressive symptoms. However, besides psychological symptoms, the study indicates potential physiological issues from pesticide exposure, such as renal (kidney) and hepatic (liver) issues. Studies like this one can directly pinpoint risks of developing depression, especially among agricultural workers and landscapers who use pesticides. Usually, research on pesticide-induced diseases commonly investigates pesticide exposure concerning the development of various physical illnesses. However, previous studies show that occupational risks of developing depression are high in agriculture, where pesticide use is rampant. Acute exposure to chemicals, including organophosphate, organochlorine, triazine, and carbamate pesticides, tends to put farmers at greater risk of suicide than the general population. There is a lack of information connecting pesticide exposure to the subsequent psychological (psychiatric) effects on the general population. Although the etiology of depression—and many other psychiatric disorders—is often genetic, […]

(Beyond Pesticides, October 25, 2023) A study published in Environmental Pollution finds farming and organophosphate (OP) pesticide exposure are risk factors for depression, with pesticide poisoning being a risk factor for suicidal behavior. Additionally, psychiatric disorder prognosis affects men more than women, with depression and suicidal outcomes more common among pesticide-exposed males. Age also affected depression and suicidal consequences, with elevated rates among older farmers. Research on pesticide-induced diseases commonly investigates pesticide exposure concerning the development of various physical illnesses. However, previous studies show that occupational (work-related) risks of developing depression are high in agriculture, where pesticide use is widespread. Acute exposure to chemicals, including organophosphate, organochlorine, triazine, and carbamate pesticides, tends to put farmers at elevated risk. More study is needed on pesticide exposure and similar psychological (psychiatric) effects in the general population. According to the World Health Organization (WHO), depression affects 322 million people globally, with the number of diagnosed patients increasing by 18.4% from 2005 to 2015. Although the etiology of depression—and many other psychiatric disorders—is often genetic, studies suggest that other etiological factors, like pesticide exposure, play a role in depression incidents. Poor mental health has a tangible influence on physical health (e.g., depression and cardiovascular disease); therefore, the combination of pesticide exposure […]

(Beyond Pesticides, July 6, 2023) A study published in Environmental Health Perspectives finds concentrations of organophosphate (OP) metabolites in urine during the prenatal phase have links to adolescent/young adult externalizing (e.g., hyperactivity, aggression, attention problems) and internalizing (e.g., depression) behavior problems. Thus, prenatal exposure to OP pesticides can permanently affect behavioral health as children mature into adulthood. This study adds to the growing body of research reinforcing the adverse effects of organophosphate (OP) exposure on cognitive health and neurological development, especially for infants and children. Prenatal development is one of the most vulnerable periods of exposure, as the fetus is most susceptible to the harmful effects of chemical contaminants. Many studies indicate that prenatal and early-life exposure to environmental toxicants increases susceptibility to diseases, from learning and developmental disabilities to cancer. Given research links to pesticide exposure and neurological and cognitive development, studies like this can help government and health officials identify how pesticides’ impact on the brain elevates health concerns. Researchers gathered two urine samples from mothers during pregnancy (at weeks 13 and 26) and five urine samples from offspring from the ages of six months to five years old to measure urinary dialkylphosphates (DAPs) (nonspecific OP metabolites). Subsequently, the study also assesses reports of […]

(Beyond Pesticides, June 7, 2023) A systematic review of scientific literature published in Environmental Research on the development of mood disorders among pesticide applicators (farmers, landscapers, etc.) finds an increased risk of depression symptoms over the last decade. The evidence in the review highlights the presence of pesticide-specific biomarkers and biomarkers of depression that determine the positive association between pesticide exposure and the development of depressive symptoms. With more high-quality longitudinal studies to control sociocultural variables, researchers can directly pinpoint risks of developing depression, especially among agricultural workers and landscapers who use pesticides. Research on pesticide-induced diseases commonly investigates pesticide exposure concerning the development of various physical illnesses. However, previous studies show that occupational (work-related) risks of developing depression are high in agriculture, where pesticide use is rampant. Acute exposure to chemicals, including organophosphate, organochlorine, triazine, and carbamate pesticides, tends to put farmers at greater risk of suicide than the general population. There is a lack of information connecting pesticide exposure to the subsequent psychological (psychiatric) effects on the general population. Additionally, household pesticide exposure varies from occupational exposure via exposure frequency, duration, intensity, and type.  According to the World Health Organization (WHO), depression affects 322 million people globally, with the number of diagnosed patients increasing by 18.4% from 2005 to […]

(Beyond Pesticides, May 13, 2021) Scientists are advocating for stricter pesticide bans to lower deaths from deliberate pesticide ingestion. The request for this toxic pesticide ban follows a University of South Australia study detailing discrepancies in World Health Organization (WHO) classifications of pesticide hazards that rely on animal rather than human data. Previous studies demonstrate an increased risk of developing depression, especially among agricultural workers and landscapers who use pesticides. Acute exposure to chemicals, including organophosphate and carbamate pesticides, tends to put farmers at greater risk of suicide than the general population. This research highlights the significance of assessing pesticide toxicity and health effects using human data rather than animals to understand health effects resulting from pesticide exposure. Society tends to rank mental health risks second to physical health. However, pesticide poisonings account for one in five suicides globally. Therefore, it is vital to address the accessibility and necessity of conventional pesticide use to safeguard human well-being, especially in countries lacking adequate chemical regulations. The study’s scientists note, “The human data for acute toxicity of pesticides should drive hazard classifications and regulation. We believe that a global benchmark for registration of pesticides should include a less than 5% case fatality after self-poisoning, which could prevent many […]

(Beyond Pesticides, June 18, 2020) Residential exposure to household pesticide products increases the risk of developing symptoms associated with depression, according to a study published in Environmental Research by researchers at Medical College of Georgia—Augusta University, School of Medicine—Jinan University, and Guangzhou Center for Disease Control and Prevention (CDC), China. Research on pesticide-induced diseases commonly investigates pesticide exposure concerning the development of various physical illnesses, and previous studies show there are occupational risks of developing depression, especially in agriculture where pesticide use is rampant. However, there is a lack of information connecting pesticide exposure to the subsequent psychological (psychiatric) effects on the general population. Additionally, household pesticide exposure varies from occupational exposure via exposure frequency, duration, intensity, and type. This research highlights the significance of researching potential mental health effects resulting from pesticide exposure, especially as society tends to rank mental health risks second to physical health. The study’s scientists note, “Our results highlight the importance of the cautious use of household pesticides because the chronic effects of poisoning may contribute to an elevated risk of depression.” According to the World Health Organization (WHO), depression affects 322 million people globally, with the number of diagnosed patients increasing by 18.4% from 2005 to 2015. Although the etiology of depression—and […]

(Beyond Pesticides, October 15, 2014) A new study published in Environmental Health Perspectives finds a strong relationship between the use of pesticides and depression in farmers. One specific class of pesticide, organochlorines, was associated with a 90% higher chance of being diagnosed with depression. For fumigants, the increased risk was up to 80 percent. This study echoes the conclusion from an earlier French study which also reported that farmers using pesticides face  a greater risk of developing depression. The study, Pesticide Exposure and Depression among Male Private Pesticide Applicators in the Agricultural Health Study, examines possible associations between pesticide exposure and depression among male private pesticide applicators in the Agricultural Health Study (AHS). Over 21,000 applicators who enrolled in the study in 1993—1997 were followed and examined. The applicators were asked about depression when enrolled in the study and then again around 2010. Previous work with this AHS sample found a higher prevalence of depression among male applicators who reported past pesticide poisoning or use of pesticides from several different classes. However, this study examines specific pesticides, and finds that two types of pesticides, fumigants and organochlorine insecticides are positively correlated with depression and cumulative days of use. Those exposed […]
