U.S. EPA Advisers Raise Concerns About Perchlorate Cleanup Goal

摘要

Small children are not sufficiently protected from exposures to perchlorate under the preliminary reme-diation goal set in late January by the U.S. Environmental Protection Agency (EPA) for Superfund sites, according to the agency's Children's Health Protection Advisory Committee (CHPAC). The new cleanup target of 24.5 ppb "is not supported by the underlying science and can result in exposures that pose neurodevelopmental risks in early life," wrote Melanie Marty of California's Office of Environmental Health Hazard Assessment, who chairs the CHPAC panel, in a March 8 letter to the EPA administrator.
