With its image of an ashtray overflowing with cigarette butts, the cover of the February issue of Environmental Health Perspectives (EHP)(https://ehp03.niehs.nih.gov/home.action) is a fitting backdrop for the journal's feature news story - "Does the Smoke Ever Really Clear? Thirdhand Smoke Raises New Concerns." The article takes a look the mixture of toxicants that lingers on surfaces and resorbs into the air, well after the smoke itself clears, and discusses why some researchers believe this so-called thirdhand smoke may be a cause for concern. The issue's second news story, "Avoiding Health Pitfalls of Home Energy-Efficiency Retrofits," examines some of the unhealthy exposures that can accompany popular home weatherization measures.

In this month's podcast(https://ehp.niehs.nih.gov/category/news/podcasts/), NIEHS grantee and Heinz Award winner Frederick vom Saal, Ph.D.(http://biology.missouri.edu/people/?person=97) Exit NIEHS, talks to host Ashley Ahearn about new research addressing the question of whether results seen in laboratory animals exposed to bisphenol A can be reasonably extrapolated to humans.

Among the reviews and research studies included in this issue are:

  • Chemical Contamination of U.S. Butter
  • PBDEs and Thyroid Hormone-Mediated Neuronal Development
  • Mercury-Containing Products in New York City
  • Heat Waves and U.S. Mortality Risk
  • Arsenic-Induced Inflammation in Placenta
