Take Action: Air Contamination from Agricultural Fumigants Threatens Farmworkers and Their Communities

(Beyond Pesticides, May 22, 2023) Since most of the domestically produced fresh produce we eat comes from California, what happens in the state is of concern to most consumers. The California Department of Pesticide Regulation (DPR) has made minor adjustments to its proposal to remove existing limits on the use of 1,3-dichloropropene (1,3-D or Telone), allowing Californians to breathe much more 1,3-D than state toxicologists at the California Office of Environmental Health Hazard Assessment—charged with establishing safe limits of exposure and enforcing Prop 65—say is safe, highlights the dangers to which farmworkers are routinely exposed. It is outrageous that the U.S. Environmental Protection Agency (EPA) would allow farmworkers—whose labor was judged “essential” during the pandemic—to be routinely exposed to highly toxic pesticides, which could be replaced by organic practices. You may have commented on this early in the year, and now we need to follow up with a strong message to protect those who harvest the nation’s food.  Tell EPA, Congress, and CDPR to cancel the registration of all toxic soil fumigants and encourage organic alternatives. 1,3-D is a pre-plant soil fumigant registered for use on soils to control nematodes. It is allowed on all crops and is often used with chloropicrin, another highly toxic […]

Death Tied to 1,3-D (Telone) Fumigant Highlights Sensitivity of the Brain to Pesticide Exposure

(Beyond Pesticides, March 23, 2023) A case report article published in Frontier in Public Health confirms one of the first reported deaths from inhalation of the fumigant 1,3-dichloropropene (1,3-D or Telone) during work, resulting in acute renal (kidney) failure, hyperkalemia (high potassium levels in the blood), and brain edema (swelling). 1,3-D is a highly toxic fumigant used on a variety of crops, but primarily on potatoes, tobacco, strawberries, peanuts, and tomatoes to manage unwanted nematodes in soils. The chlorine-containing compound used in a greenhouse space entered the body of a 50-year-old man in China, being absorbed through the respiratory tract. Despite dilution from his wife, the compound was still strong enough to cause harm to human health. Without proper ventilation and personal protective equipment, wearing merely a surgical mask did not adequately defend against exposure to 1,3-D. This case represents the broader issue of how toxic chemical compounds can enter the body, causing physiological damage. Specifically, pesticides can increase the permeability (absorptiveness) of the blood-brain barrier that filters various molecules entering the brain from the circulatory system. However, the permeation of pesticide molecules elevates the expression and accumulation of soluble proteins in the brain involved in neuroinflammation, which plays a critical role in […]

Four Pesticides Restricted to Protect Salmon, Thousands of Other Endangered Species Imperiled

(Beyond Pesticides, February 10, 2023) The U.S. Environmental Protection Agency (EPA) announced, on February 1, new measures to protect 28 endangered salmon species (including steelhead trout) from the use of four pesticides that threaten them and their critical habitats. Those compounds comprise three herbicides — metolachlor, bromoxynil, and prometryn, and one soil fumigant, 1,3-Dichloropropene. The protections, aimed at salmon populations in Washington, Oregon, and California, are meant to reduce impacts from pesticide runoff and spray drift, and to minimize potential “take.” (Under the Endangered Species Act (ESA), “take” means, essentially, the unintentional harming or killing of an individual of a protected species — in this case, harm or death from exposures to these toxic pesticide compounds.) Beyond Pesticides and other advocates have for years warned that multiple pesticides are threats to Northwest salmon and other species at risk. This EPA announcement is the second of two, recently, that offer slight redress to the agency’s historical failures to act (see more below). Indeed, advocates have engaged in multiple litigation efforts over the years to try to force EPA to take action; EarthJustice in 2001 noted some early instances. As Chemical and Engineering News says pointedly, “Environmental groups, which have been suing […]

Hazardous Fumigant in Food Production Harmful to Farmworkers, Groups Call for Ban

(Beyond Pesticides, January 3, 2023) The California Department of Pesticide Regulation (DPR) announced new rules that remove existing limits on the use of 1,3-dichloropropene (1,3-D or Telone), allowing Californians to breathe much more 1,3-D than state toxicologists in the Office of Environmental Health Hazard Assessment (OEHHA) say is safe and highlighting the dangers to which farmworkers are routinely exposed. It is outrageous that the state of California and the U.S. Environmental Protection Agency (EPA) would allow farmworkers—whose labor was judged “essential” during the pandemic—to be routinely exposed to highly toxic pesticides, which could be replaced by organic practices. While the state of California describes its action as increasing protection, advocates point to continued use, unacceptable harm, and the availability of alternative organic agricultural production methods that eliminate the use of 1,3-D. Since over a third of the country’s vegetables and three-quarters of the country’s fruits and nuts are grown in California, most people who buy their food in a grocery store have a stake in how food is grown in the state and the impact that it has on those who live and work there. Tell the state of California, U.S. EPA, an the U.S. Congress to cancel the registration […]
