The May issue of Environmental Health Perspectives (EHP)(http://ehp03.niehs.nih.gov/home.action) highlights a longstanding threat to water quality with a cover story on "Phosphorus Paradox: Scarcity and Overabundance of a Key Nutrient." The story explores the paradoxical dilemma that even as access to phosphate rock dwindles, far too much phosphorus is ending up in waterways.

A second news feature, "Tools for Tracking Antibiotic Resistance," examines efforts by governments and agencies to protect the efficacy of medically important antibiotics through a variety of monitoring and educational strategies.

In this month's Researchers' Perspective podcast(http://ehp03.niehs.nih.gov/static/podcasts.action), University of California investigators Tracey Woodruff, Ph.D., and Rachel Morello-Frosch, Ph.D., discuss with series host Ashley Ahearn the major ethical and logistical dilemmas involved in communicating chemical body burdens to participants in studies.

NTP lead scientist Kristina Thayer, Ph.D., and Associate Director John Bucher, Ph.D., contribute an editorial in this issue on the newly formed NTP Office of Health Assessment and Translation. The new office replaces the novel NTP Center for the Evaluation of Risks to Human Reproduction (CERHR), founded in 1998 and currently directed by Thayer, and reflects the evolution of CERHR into the NTP focal point for the thoughtful and deliberative integration of relevant information of all types in health assessments for the protection of public health.

Featured studies this month include the following:

  • Epigenetic Effects of 1,3-Butadiene
  • Intergenerational Differences in Human PCB Exposures
  • Traffic-Related Air Pollution and Cognitive Function
  • Heat Waves and Mortality under Global Climate Change
  • Perinatal Dioxin Exposure Can Impair Semen Quality
  • Arsenic Exposure and Infant Morbidity in Bangladesh

EHP also continues into May its month-long celebration of Earth Day with a special page(http://ehponline.org/earthday2011) published April 22. The page features a compilation of recent EHP news features, perspectives, commentaries, reviews, science education lessons, and podcasts centered around Earth Day themes (see related story(http://www.niehs.nih.gov/news/newsletter/2011/may/inside-ehp/index.cfm)).
