Unregulated Greenhouse Gas Emissions from Potent Pesticide Impact Climate Crisis and Public Health

(Beyond Pesticides, May 2, 2024) In the midst of a climate crisis and a lack of government recording of atmospheric measurements of sulfuryl fluoride (SO2F2), a study of the estimated emissions of sulfuryl fluoride throughout the U.S. shows elevated levels being released in California. The study, performed by researchers from Johns Hopkins University’s Department of Environmental Health and Engineering, University of California’s Scripps Institute of Oceanography, and National Oceanic and Atmospheric Administration’s (NOAA) Global Monitoring Laboratory, uses measurements from the NOAA Global Greenhouse Gas Reference Network and a geostatistical inverse model. Sulfuryl fluoride is a fluoride compound and pesticide used primarily for the extermination of drywood termites and beetles—linked to increased greenhouse gas emissions and having acute exposure consequences—with little data collected or reported on the amount of sulfuryl fluoride being used and released into the atmosphere. There is a long history of limited protections for the public centered around sulfuryl fluoride, with regulations from the U.S. Environmental Protection Agency (EPA) not addressing both dietary and nondietary exposure to fluoride compounds and the body burden this creates. With the dismissal of aggregate risk exposure, public health and safety and environmental sustainability are not prioritized. Organic alternatives have been left out of the conversation, […]

Children’s IQ Negatively Impacted by Maternal Fluoride Exposure, According to Study

(Beyond Pesticides, August 21, 2019) A birth cohort study in Canada found elevated levels of fluoride exposure during pregnancy are associated with lower IQ scores in 3 to 4-year-old children. This new research, published in the journal JAMA Pediatrics, builds on previous analyses that suggest high fluoride exposure is related to adverse effects to children’s neurodevelopment. Researchers recommend that pregnant mothers should reduce fluoride intake during pregnancy. Noting the controversy of the study, JAMA Pediatrics editor Dr. Dimitri Christakis said it was subjected to “additional scrutiny for its methods and the presentation of its findings.” The Maternal-Infant Research on Environmental Chemicals (MIREC) program recruited pregnant mothers to participate in the study from 2008-2011. A total of 601 mother-child pairs from 6 major cities participated; 41% of them lived in cities with fluoridated municipal water. Exposure was measured through urine samples as well as self-reported maternal daily intake. Children were between ages 3 and 4 when tested for IQ. A 1mg/L increase in maternal urinary fluoride is associated with a 3.7-point decrease in IQ. These findings echo a previous study in Mexico that found a 6-point lower IQ score in school-age children associated with a 1mg/L in maternal urinary fluoride. Women who […]
