DDT Exposure During Early Life Associated with Increased Risk of Breast Cancer

(Beyond Pesticides, February 20, 2019) Women exposed to DDT during ‚Äėearly windows of susceptibility‚Äô in their childhood are at increased risk of developing breast cancer, according to new research published in the Journal of the National Cancer Institute. Nearly 75 years after the chemical was first used in the U.S., and 50 years after its ban, DDT is continuing to adversely affect the health of Americans. The data brings needed attention to the dangers of early-life pesticide exposure, and underlines the need to take a precautionary approach to the introduction of biocides in our environment so that future generations do not suffer from the same mistakes of the past. “What we have learned is that timing really matters. We know that if harmful exposures occur at times when breast tissue is rapidly changing, such as during puberty, they impact breast development in ways that can later result in cancer,” said lead author Barbara A. Cohn, PhD, of the Public Health Institute’s (PHI) Child Health and Development Studies. “The research published today suggests that DDT affects breast cancer as an endocrine disruptor, that the period of time between first exposure and cancer risk seems to be around 40 years–and that other […]

EPA-Registered Herbicide Found to Trigger Inflammation Linked to Onset of Multiple Sclerosis

(Beyond Pesticides, February 5, 2019) Linuron, an herbicide registered for use by the U.S. Environmental Protection Agency (EPA), yet recently banned in Europe due to health concerns, appears to trigger inflammatory signals that have been linked to the onset of Multiple Sclerosis (MS). This new evidence, published in the journal Cell by researchers at Brigham and Women‚Äôs Hospital in Boston, MA, indicates that exposure to chemicals and pesticides in the environment may be a risk factor in the development of neurodegenerative diseases. ‚ÄúWe created a platform to systematically investigate the understudied effects of environmental exposures,‚ÄĚ said study coauthor Francisco Quintana, PhD. ‚ÄúThe goal of our work is to return results that can guide future epidemiological studies and identify actionable targets.” Researchers began their investigation with 976 chemicals identified by¬†EPA‚Äôs ToxCast program, an inventory of compounds that have undergone screening for a battery of laboratory tests. Within that inventory, 75 chemicals, including linuron, were found to interfere with the signaling pathways linked to MS. To confirm the adverse impacts, scientists used the embryos of zebrafish, animals often used as models in laboratory research. The zebrafish embryos were altered to contain low levels of myelin, a protein that protects nerve cells, as […]
