NTP Study Of Low-Level Lead Health Effects Could Drive EPA Regulations

摘要

The National Toxicology Program (NTP) is developing an analysis of the current scientific evidence surrounding the human health risks of lead at extremely low levels, particularly reproductive effects, an analysis that could drive a host of new EPA regulations governing air emissions, lead dust, drinking water and other environmental releases of the metal.rnThe National Institute of Occupational Safety and Health (NIOSH), which intends to use NTP's conclusions when considering new recommended exposure limits (RELs) for workers, requested that NTP's Center for the Evaluation of Risks to Human Reproduction (CERHR) conduct the analysis in 2007 to address the disconnect between its current occupational exposure limits of 40 micrograms per deciliter (ug/dL) in adult workers, including women of child-bearing age, and data showing adverse effects in children at much lower levels, a NIOSH source says.
