lead poisoning

Researchers at the McKelvey School of Engineering at Washington University in St. Louis found that the hazards of switching disinfectants in water systems — increased lead levels — can be mitigated if the change is done correctly.

Communities exposed to toxic lead emissions recently won an important victory in federal court through a case filed by the Interdisciplinary Environmental Clinic (IEC) at Washington University in St. Louis. “The court chastised the Environmental Protection Agency (EPA) for long-neglecting its duty to review the lead standard every five years, and placed the agency on a firm schedule for conducting the review,” says Maxine I. Lipeles, IEC director and professor of law and engineering. “Because the lead standard must be revised to protect public health, and the existing standard is out of date, we believe that the EPA is virtually required to revise the standard downward. That would help protect children in communities across the country where smelters and other facilities emit significant amounts of lead into the air. The decision should also caution the EPA to act more promptly in reviewing the other five national ambient air quality standards * for nitrogen oxides, ozone, sulfur dioxide, carbon monoxide, and particulate matter.”
