(Beyond Pesticides, September 30, 2021) Individuals working or living in areas with frequent neurotoxic pesticide use experience more amyotrophic lateral sclerosis (ALS) incidences than the general population. The study, published in NeuroToxicology, finds a positive association between sporadic (non-genetic, spontaneous) ALS incidences among individuals exposed to neurotoxic pesticides. Amyotrophic lateral sclerosis (or Lou Gehrig’s disease) is a neurodegenerative disease that affects the nerves in the brain and spinal cord. As many as 16,000 – 20,000 Americans live with this condition, which weakens muscle/motor function leading to loss of muscle control for walking, talking, eating/swallowing, and breathing. Severe ALS progression is fatal and has no current cure. Although research supports genetic factors play a role in disease etiology (cause), most ALS cases do not result from genetic inheritance. Several research studies demonstrate exposure to environmental or work-related toxicants (i.e., pesticides) predispose humans to the disease. With researchers predicting a global ALS incidence increase of 69% by 2040, identifying ALS’s causal factors are important to future research. Therefore, research like this showcases the importance of assessing aggregate health risks associated with toxic chemical exposure, especially for illnesses, which are not curable. In this study, the researchers note, “[W]e identified pesticides applied to crops in the area of […]

(Beyond Pesticides, September 9, 2021) A new study published in Toxicology Reports finds the same chemicals that disrupt the endocrine (hormone) system also disrupt the nervous system. Endocrine disruptors are xenobiotics (i.e., chemical substances like toxic pesticides foreign to an organism or ecosystem) present in nearly all organisms and ecosystems. The World Health Organization (WHO), European Union (EU), and endocrine disruptor expert (deceased) Theo Colborn, Ph.D., classify over 55 to 177 chemical compounds as endocrine disruptors, including various household products like detergents, disinfectants, plastics, and pesticides. Past research shows exposure to endocrine-disrupting pesticides adversely affects human health, from reproductive function to cancer development, and effects can span generations. However, this study is one of the few to evaluate associations between endocrine-disrupting chemicals and neurological function. Although the etiology (cause) of many sporadic (non-heritable) neurological diseases are unknown, scientists suggest exposure to environmental toxicants plays a role in disease development. Therefore, government and health officials have been urged to consider how exposure to endocrine-disrupting chemicals can impact bodily function and development apart from hormone disruption.  In the body, cells communicate through electrical or chemical signals transmitted within the nervous or endocrine system. Studies find exposure to endocrine-disrupting chemicals has a direct and indirect impact on hormone function and development. However, researchers investigated whether […]

(Beyond Pesticides, May 28, 2020) Exposure to agricultural and industrial pesticides, solvents (thinners), electromagnetic fields, and heavy metals predispose humans to amyotrophic lateral sclerosis (ALS), according to an Italian research study, “Environmental and Occupational Risk Factors of Amyotrophic Lateral Sclerosis: A Population-Based Case-Control Study,” published in the International Journal of Environmental Research and Public Health. Although research supports ALS’s genetic etiology, epidemiologic research associating ALS risks and to environmental, or work-related risk factors (i.e., pesticide use, pollutant exposure, heavy metal exposure, etc.) has been inconsistent and non-definitive. This research demonstrates the importance of assessing aggregate health risks associated with occupational pesticide exposure, especially when determining potential exposure routes in specific occupational sectors. In the study, researchers note, “In particular, having an occupation in the agricultural sector, especially with a long duration of the working activity as well as occupational exposure to some chemicals…might increase ALS risk.” While scientists extensively study the epidemiology of amyotrophic lateral sclerosis (ALS)—a rare, yet fatal neurodegenerative disease—occupational and environmental hazards inducing random (sporadic) or hereditary ALS diagnoses remain vague. With researchers predicting a global ALS incidence increase of 69% by 2040, identifying ALS’s causal factors are important to future research. In this research, Italian researchers conducted a case-control, […]

(Beyond Pesticides, May 16, 2016) Pesticide exposure may increase the risk of amyotrophic lateral sclerosis (ALS), according to a study entitled Association of Environmental Toxins With Amyotrophic Lateral Sclerosis, which was  published in JAMA Neurology. ALS, also known as Lou Gehrig’s disease, is a progressive neurodegenerative disease that affects nerve cells in the brain and spinal cord. The study, which investigated a total of 122 persistent environmental pollutants, including organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), and brominated flame retardants (BFRs), found that pesticide exposure increased ALS risk five-fold. Researchers conducting the study  looked at 156 patients with ALS and 128 without the disease. Participants were asked about occupational and residential exposure to environmental toxicants  and blood samples were taken to measure their concentrations. Researchers found that the organochlorine pesticides pentachlorobenzene and cis-chlordane increased ALS risk two-fold and nearly six-fold, respectively. This study does not prove that pesticides cause ALS, but it does build on an association suggested in previous research, study co-author Stephen Goutman, MD, told  HealthDay. Dr. Goutman recommends avoiding pesticides. This is especially wise for anyone with a family history of ALS, he added. The link between pesticide exposure and neurological damage has been studied extensively. In 2008, […]
