(Beyond Pesticides, October 15, 2024) In Environmental Epidemiology, researchers from Columbia University and the University of Southern California, along with representatives from the nonprofit Comite Civico del Valle in Brawley, California, report the heightened risk of wheezing for five- to twelve-year-olds in the rural communities of California’s Imperial Valley. Through a school-based survey, the authors find associations between living near pesticide applications and more wheeze symptoms among the children. According to the authors, residents of the Imperial Valley, which is located near the border between the United States (U.S.) and Mexico, “are primarily Latino, 1 in 3 children live in poverty, and there is a 20% unemployment rate. The county faces poor air quality and excess particulate matter levels. Further, one in five children is diagnosed with asthma and the rate of asthma-related pediatric emergency room visits and hospitalizations is two times the CA state average.” This highlights the disproportionate risk for residents in this area regarding environmental exposure to harmful chemicals. Children are already more susceptible to health complications following pesticide exposure, as they take in greater amounts of toxic chemicals relative to their body weight and have still-developing organ systems. Young children in environments with higher levels of […]

(Beyond Pesticide, August 27, 2020) The latest research finds that pesticides and fertilizers supersede fossil fuels as the greatest contributor of sulfur emissions in the environment, according to U.S. National Science Foundation (NSF)-funded study, published in Nature Geoscience. Particularly, atmospheric sulfur dioxide and reactive sulfur emissions contribute to sulfur deposition via acidic rain and snow, causing a multitude of human and animal of health problems and environmental degradation. Although some U.S. policy regulations curb sulfur emissions from atmospheric sources, alternative sulfur inputs from agricultural sources can cause similar issues as atmospheric sulfur emissions, including acid rain. With peak sulfur concentrations from agricultural outputs up to ten-fold higher than previous 20th-century sulfur levels, studies like these are significant in understanding how underrepresented pollution sources may contribute to overall environmental pollution. Lead author of the study, Eve-Lyn Hinckley, Ph.D., states, “We have an imperative to understand the impact that we’re having on the environment. And then we need to work together towards solutions to mitigate those effects.” Sulfur is a naturally occurring element found in vast, underground deposits. Although relatively stable underground, it is highly reactive once it reaches the surface, transforming into chemical compounds, like sulfur oxides, upon exposure to oxygen. Over […]

(Beyond Pesticides, December 12, 2018) Costa Rica is currently experiencing exponential growth in its banana and pineapple farming industries and with it an increase in intensive pesticide applications. Recent studies in Costa Rica identified evidence of increasing fur discoloration in black mantled howler monkeys ((Alouatta palliata) as a result of their exposure to sulfur-based pesticides. Coloration in Howler monkeys are limited to black, gray, and dark brown, but researchers found several monkeys with yellow patches on their tails and legs. The change in pigmentation is directly correlated to the consumption of plants inadvertently exposed to sulfur-based pesticides sprayed at (and drifting from) nearby farms. The use of pesticides is not only hazardous to nearby wildlife, but communities as well. It is an issue that seems to play out repeatedly both in Costa Rica and in the U.S. The use of pesticides, and more importantly pesticide drift, continues to be a pervasive issue with severe human and environmental health consequences. Pesticide drift occurs in the form of mist, particles, or vapor (gas) and are usually carried by air (and oftentimes water) currents. Typically, fumigants (gaseous pesticides) are most likely to drift. When used, pesticides regularly spread further than the established application […]

(Beyond Pesticides, January 26, 2010) Pesticide use declined in California for a third consecutive year in 2008, according to the state’s Department of Pesticide Regulation (DPR). Approximately 162 million pounds of reported pesticides were applied statewide, a decrease of nearly 10 million pounds – or 6 percent – from 2007. Pesticide use in production agriculture fell by 9.6 million pounds and in most other categories as well, including structural pest control and landscape maintenance. Reports are mandatory for agricultural and pest control business applications, while most home, industrial and institutional uses are exempt. DPR Director Mary-Ann Warmerdam emphasized that pesticide use varies from year to year depending on a number of factors, including weather, pest problems, economics and types of crops planted. Increases and decreases in pesticide use from one year to the next or in the span of a few years do not necessarily indicate a general trend. “California experienced another dry winter and spring in 2008, which helps explain why fungicides showed the greatest decrease in use by both pounds and acres treated,” Ms. Warmerdam said. “Herbicide use also fell by pounds and acres treated, indicating fewer weeds.” Sulfur was again the most highly used pesticide in 2008 […]

(Beyond Pesticides, December 8, 2008) A new study by a National Institute for Occupational Safety and Health (NIOSH) researcher finds the pesticide poisoning incidence rate among U.S. agricultural workers is thirty-nine times higher than the incidence rate found in all other industries combined. The study, “Acute Pesticide Poisoning Among Agricultural Workers in the United Sates, 1998-2005,” published in the December issue of the American Journal of Industrial Medicine, is believed to be the first detailed multi-state assessment of acute pesticide poisonings among agricultural workers. From 1998 to 2005, a total of 3,271 cases of acute occupational pesticide-related illness/injury among agricultural workers were identified in ten states. According to EPA, the Worker Protection Standards are designed to reduce the risk of injury or illness to agricultural field workers resulting from exposure to pesticides. Although the WPS was expanded in 1995 and in 2005 EPA developed a new WPS How to Comply (HTC) Manual, the NIOSH findings indicate that agricultural workers continue to have an elevated risk for acute pesticide poisoning. Furthermore, female agricultural workers experienced nearly twice the risk of pesticide poisoning of male agricultural workers. The most common factors that contributed to pesticide exposure included off-target drift, early reentry into […]
