A study of Northern California waterways has made some troubling discoveries about a widely used group of pesticides and the role of homeowners and businesses in putting them there.
The findings should prompt residents to reflect on their household practices. It also should lead to further scientific investigation of the role these pesticides are playing in the multifaceted crisis of the Sacramento-San Joaquin Delta.
The study, led by a University of California at Berkeley toxicologist, focused on pyrethroids. These are man-made pesticides commonly used in household insecticides, lawn care products and pet sprays.
