(Beyond Pesticides, March 26, 2024) The authors of a case study in Canale D’Aiedda, Taranto, Italy, published in Scientific Reports, conclude that, “[T]he results of monitoring and modeling activities revealed a chronic risk associated with the presence of Cu [copper] from November to April in several river reaches and acute risk associated to the presence of glyphosate in several reaches mainly in the wet season.”  According to the authors, “The most important factor influencing the chronic risk for Cu were the combination of two factors: the high surface runoff and the Cu applications. The most important factor influencing the glyphosate peaks of concentration is the streamflow.” The authors of the study measure the flow of pesticide concentrations through the soil and water assessment tool (SWAT). The ecotoxicological data was collected at two stations in Germany that flow into Italy, within the Canale d’Aiedda basin. The streamflow was monitored between August 2017 and December 2019. Out of hundreds of pesticides and six metabolities investigated in this study, “only traces of copper and glyphosate were found.” The authors continue, “The banks and the bed of the river system are almost all covered by concrete. The hydrological regime is natural and intermittent in […]

(Beyond Pesticides, May 23 2023) New research is zeroing in on the role of 10 commonly used pesticides in the development of Parkinson’s. Published in the journal Nature Communications by a team of scientists lead by researchers at the University of California, Los Angeles, the study focused on the toxicity of these pesticides to neurons that have been found to lead to the presentation of the disease. Research is increasingly focusing on environmental exposures, and pesticides in particular, as a major factor in the development of Parkinson’s. This study adds further evidence that this line of research is a valid and worthwhile undertaking for the nearly one million people in the United States struggling with this incurable disease. [The authors note that the herbicide paraquat’s strong connection to Parkinson’s is not addressed in this study, but is the focus of a separate manuscript.] Scientists sought to further focus on which pesticides were most likely to be playing a role in Parkinson’s development. Records from California’s vast pesticide use database aided the search. From a comprehensive pesticide-wide association study, 53 of 288 pesticides screened were found to be linked to Parkinson’s. Scientists then took these 53 pesticides and conducted live-cell imaging […]

(Beyond Pesticides, January 12, 2023) Exposure to certain pesticides among individuals diagnosed with Parkinson’s disease (PD) can increase the risk of symptom progression. According to a study published in Science of the Total Environment, nearly 20 percent of pesticides associated with the onset of PD also increase the risk of faster decline in motor and non-motor function. Several studies find exposure to chemical toxicants, like pesticides, has neurotoxic effects or exacerbates preexisting chemical damage to the nervous system. Past studies suggest neurological damage from oxidative stress, cell dysfunction, and synapse impairment, among others, can increase the incidence of PD following pesticide exposure. Despite the association between PD onset via pesticide exposure patterns, few epidemiologic studies examine the influence pesticides have on worsening motor and non-motor symptoms in PD. Parkinson’s disease is the second most common neurodegenerative disease, with at least one million Americans living with PD and about 50,000 new diagnoses annually. The disease affects 50 percent more men than women, and individuals with PD have a variety of symptoms, including loss of muscle control and trembling, anxiety and depression, constipation and urinary difficulties, dementia, and sleep disturbances. Over time, symptoms intensify, but there is no current cure for this fatal disease. While […]

(Beyond Pesticides, September 13, 2021) The National Organic Standards Board (NOSB) is receiving written comments from the public through September 30. This precedes the upcoming public comment webinar on October 13-14 and online meeting October 19-21—in which the NOSB deliberates on issues concerning how organic food is produced. Written comments must be submitted through Regulations.gov. As always, there are many important issues on the NOSB agenda this Fall. For a complete discussion, see Keeping Organic Strong (KOS) and the Fall 2021 issues page. In the spirit of “continuous improvement,” we urge you to submit comments (please feel free to use our comments on the KOS page) that contribute to an increasingly improved organic production system. The Organic Foods Production Act (OFPA) requires that all synthetic materials used in organic production be approved by the NOSB, included on the National List, and reassessed every five years. Among those up for sunset review this Fall are some controversial materials—copper sulfate, carrageenan, and list 3 “inerts.” In addition, the NOSB is once more considering a petition to allow the antibiotic kasugamycin in fruit production. Copper sulfate is used in organic rice production to control algae and an invertebrate known as tadpole shrimp. It […]
