NIEHS SRP Risk e Learning Webinar Series

This seminar was the first in a three part series that coincides with the Superfund Research Program(SRP) 25th Anniversary and the 10th Anniversary of the SRP Risk e-Learning webinars. The SRP chose this opportunity to highlight the Program's accomplishments in the area of arsenic research. Since its inception, the SRP has funded work to understand the consequences of exposure to arsenic at the molecular and population levels.

Dr.  Joseph Graziano, presents a historical overview of the global human health issues related to drinking water. His presentation focuses on the sources and prevalence of arsenic exposures and the evolution of our understanding of the spectrum of human health impacts and how arsenic imparts negative effects. Dr. Margaret Karagas gives a brief overview of her epidemiology work that focuses on etiologic mechanisms and prevention of human cancers and other adverse health outcomes. She discusses recent findings from studies to develop biomarkers of arsenic exposure and susceptibility in a U.S. population that relies heavily on private drinking water systems where over 10% of the wells contain low to moderate levels of arsenic. She also presents information from her research, from her early studies investigating cancer risk to her more recent investigation into sources of arsenic exposure among pregnant women, e.g., via their consumption of rice and tap water, and the research translation activities that help raise awareness of the presence of arsenic in the drinking water supply.  Dr. A. Eduardo Saezwill focuses on his and Co-PI’s (Eric Betterton, Ph.D.) latest research that involves the characterization of windblown dust from mine tailings and will also touch on the University of Arizona SRP’s phytostabilization field study in the southwestern United States that uses native plants to successfully reduce the amount of dust coming off the tailings, thereby reducing potential aerial exposures.

Water conservation case study and policy report

A new Rockland County water conservation case study and policy report was released August 17 by the Center for Regional Research, Education and Outreach at SUNY New Paltz. This discussion brief updates earlier work by the authors, Stuart Braman of Lamont-Doherty and Simon Gruber of the CUNY Institute for Sustainable Cities, and places it in the context of the Hudson River valley.

PEPH Webinar

Mapping and Environmental Public Health: Visualizing Health Disparities and the Effects of Pollution broadcast on Monday, May 7th featured three scientists from Columbia University's Superfund Research Project: Lex van Geen, Steve Chillrud, and Meredith Golden.

Alexander van Geen, Associate Director of the CU SRP, presented, "Field kits for arsenic, hand-held GPS receivers, and Google Earth: key technologies for reducing exposure to arsenic contained in groundwater across South and Southeast Asia." Steven Chillrud discussed spatial and temporal variations in specific particle-associated air pollutants in NYC from both regional and local sources, in his talk, "The air we breathe in NYC and spatial variability". Finally, Meredith Golden with assistance from Tricia Chai-Onn showcased, "The NPL Superfund Footprint: Site, Population, and Environmental Characteristics Mapper", a mapping tool to assist regulatory agencies, university researchers, private and non-profit sectors, and communities located near Superfund sites.

NIEHS Awards Columbia SRP 5 year Multiproject Center Grant

The NIEHS recently announced its renewal of the Columbia University Superfund Research Program multi-project P42 grant for an additional five years, 2012-2017. The Columbia SRP will continue to focus on the complex set of geochemical, public health, and remediation issues surrounding exposures to arsenic and manganese in groundwater. The goal is to generate and communicate new scientific information for the creation and implementation of effective environmental policies to improve public health. NIEHS only made two P42 awards this year. The second is to The University of California at San Diego for the detection and models of toxicant exposure.

IRIS Inputs Requested

The EPA Integrated Risk Information System (IRIS) released its list of chemicals that have been selected for inclusion in its 2012 agenda. EPA is requesting information from the public for consideration in the development of these assessments. Two of the chemicals that may be of interest to SRP researchers are manganese and mercury. If you have publications that may be related to a risk assessment of either of these chemicals, you are encouraged to submit them at www.regulations.gov.

Variants Associated with Arsenic Metabolism and Toxicity Phenotypes in Bangladesh

A research team led by CU SRP PI Habibul Ahsan and Brandon Pierce, University of Chicago Medicine, with contributions by SRP scientists Marie Argos, Joseph Graziano, Mary Gamble, Faruque Parvez, and Vesna Slavkovich has discovered genetic variants that elevate the risk for skin lesions in people chronically exposed to arsenic, as part of the first large-scale genomic studies in a developing country. Genetic changes found near the enzyme for metabolizing the chemical into a less toxic form can significantly increase an individual's risk for developing arsenic-related disease (summary link below).

Manganese Exposure from Drinking Water and Children’s Classroom Behavior in Bangladesh

As part of the SRP child development project in Araihazar, Bangladesh, this cross-sectional study investigates the associations of manganese and arsenic in tube well water with classroom behavior among more than 200 elementary school children, 8–11 years of age.  The study examines specificity in the exposure/behavior problems by assessing both exter­nalizing and internalizing behavior. Its findings reinforce the growing concern regarding neurotoxicologic effects for children exposed to high manganese levels in drinking water.
