This Month in EHP
By Eddy Ball
(http://twitter.com/ehponline/)Environmental Health Perspectives (EHP)(http://ehp03.niehs.nih.gov/home.action) revisits lead this month in a feature article titled "Exposure on Tap: Drinking Water as an Overlooked Source of Lead," following up the December 2009 Focus. The article delves deeper into the issue by examining how public health officials react to the problem of potential exposure to lead through contaminated tap water, and discusses the role they can play in helping consumers prevent lead exposure through their tap water.
A companion story titled "Lead in Air: Adjusting to a New Standard" discusses a new petition under review by the U.S. Environmental Protection Agency to lower recently doubled monitoring threshold limits. The proposal has sparked debate over which contaminant source poses the greatest threat - industrial point sources or legacy contamination in soil from degraded house paint and gasoline.
Highlights of the issue include -
• Polyfluoroalkyl Chemicals and Cholesterol (NHANES 2003-2004)
• Peroxisome Proliferator-Activated Receptor Alpha (PPARα)-Dependent Effects of Diethylhexyl Phthalate (DEHP) on Energy Metabolism in Mice
• Childhood Asthma and Early-Life Exposure to Air Pollution
