Health Effects and Mitigation of Arsenic: Current Research Efforts and Future Directions
March 3-4, 2014
NIEHS Main Campus, Rall Building, Rodbell A, B, C
Purpose of the Workshop:
This workshop will highlight significant new and emerging research on lowdose exposure to arsenic in human health (cancer and non-cancer) such as environmental and endogenous bioavailability associated with arsenic toxicity, susceptibility to arsenic's health effects, advanced techniques to understand arsenic in health and environment, and current mitigation/remediation efforts of arsenic in the US and globally. Speakers and participants will represent a range of scientific expertise (e.g., epidemiology, human and animal toxicology, exposure, chemistry, microbiology, detection, and mitigation/remediation) and will consist of scientists from academia, federal/state/local agencies, and other researchers with an interest in this field of study. This workshop will consist of oral and poster presentations and panel discussions, as well as provide a forum to determine the current state-of-the-science in arsenic research and knowledge gaps that will inform future arsenic research programs. This meeting will be a beneficial tool to support bidirectional communication, enable one-on-one interaction between meeting participants, foster interdisciplinary collaborations, and discuss possible solutions to address identified arsenic research gaps.
Product from Workshop:
The product from this workshop will be a report/white paper/publication consisting of summaries from each of the speakers discussing knowledge gaps in their particular area of research and their vision for the future of arsenic research. In addition, the report will provide the current state of the science in arsenic research and a summary of additional knowledge gaps that arose from the workshop. Importantly, using the recommendations provided by this workshop, the report will outline suggested topic areas on which to focus upon for future arsenic research efforts.
A poster competition will be held on both days of the workshop and is open to students and Post-Doctoral Researchers to present their current arsenic research. The deadline for abstract submission is February 14, 2014. Poster guidelines will be made available soon.
