Arsenic and Immune Response to Influenza: Implications for Human Health, with Josh Hamilton
August 13, 2009 16:00 - 6 minutes - 4.56 MBThe many adverse health effects caused by chronic arsenic exposure are a concern for the hundreds of millions of people worldwide whose drinking water contains elevated levels of this naturally occurring element. A new rodent study suggests arsenic may also contribute to immune suppression. In this podcast, Josh Hamilton describes the potential implications of this finding for human health, including the possibility that arsenic exposure could help explain why certain populations ha...
Do PCBs Contribute to Childhood Leukemia? with Mary H. Ward
July 28, 2009 16:00 - 1 hour - 3.88 MBAlthough childhood leukemia is the most common childhood cancer, little is known about its causes. Incidence of acute lymphocytic leukemia, the most common childhood leukemia, is highest in industrialized countries and rose significantly between 1975 and 2004, suggesting environmental agents may play some role. In this podcast, Mary H. Ward explores the idea that polychlorinated biphenyls (PCBs) could be one such agent. Ward is the lead author of "Residential Exposure to Polychlorin...
Long-Term Effects of Bisphenol A Exposure, with Retha Newbold
June 16, 2009 16:00 - 9 minutes - 6.5 MBCities and states across the United States, as well as other nations abroad, are banning bisphenol A (BPA) due to concerns about adverse health effects of low doses of this widely used industrial compound, particularly among fetuses, infants, and young children. In this podcast, Retha Newbold describes the findings of one of the few studies to study long-term effects of prenatal exposure to BPA in mice. Newbold is a staff scientist/reproductive biologist in the NIEHS Toxicology Bran...
Phthalate Research Coming of Age? with Shanna Swan
June 12, 2009 16:00 - 6 minutes - 4.29 MBIn 2005 Shanna Swan and colleagues published groundbreaking research linking mothers' phthalate levels with altered genital development in their baby sons. In the four years since the publication of this paper, which was EHP's 2009 Paper of the Year, how much more have we learned about the health effects of phthalates? In this podcast, Swan discusses the state of the science. Swan is a professor of obstetrics and gynecology and of environmental medicine at New York's University of R...
Public Health for the 21st Century, with Kenneth Olden
June 07, 2009 16:00 - 7 minutes - 4.92 MBThe global population is undergoing sweeping changes that are shifting the balance toward an older and more urbanized population that experiences more chronic disease and a greater gap between rich and poor. In this podcast, Kenneth Olden tells what these changes mean in terms of public health challenges and how he believes we must prepare to meet these challenges. Olden was director of the NIEHS and the National Toxicology Program from 1991 to 2005. He served as NIEHS director emer...
Fossil Fuel Emissions and Children’s Health, with Frederica Perera
May 29, 2009 16:00 - 7 minutes - 5.21 MBChildren are generally more vulnerable to environmental insults because their bodies are still developing, but just as early exposures can cause lifelong adverse effects, so can early interventions produce lifelong benefits. In this podcast, Frederica Perera discusses the potential long-term benefits of reducing children's exposures to combustion emissions by mitigating modern society's reliance on fossil fuels. Perera is director of the Columbia Center for Children's Environmental ...
