The long-running Live at 9 Superfund Research Program Seminar Series returned for the 2013-2014 year with presentations by the University of Arizona Superfund Research Program (SRP) about mining-site metals and metal exposures in Arizona homes. The series was developed by SRP in collaboration with the U.S. Environmental Protection Agency (EPA) Pacific Southwest (Region 9) Superfund and Technology Liaison Michael Gill.
SRP grantees Miranda Loh, Ph.D., and Robert Root, Ph.D., travelled to EPA Region 9 headquarters in San Francisco to present "Mining Site Metals: Exposure Pathways and Bio-Assays" on July 30, 2013. Both investigators are involved at the Iron King Mine and Humboldt Smelter Superfund Site in Dewey-Humboldt, Ariz. Loh discussed her Metal Exposure Study in Homes (MESH), which is investigating whether there is a relationship between living near a former mine and smelter site and exposure to metals, particularly arsenic and lead, via soil, dust, and water. Root described his work to better understand the bio-accessibility of arsenic in mine waste.
Seminar attendees included the EPA as well as Agency for Toxic Substance and Disease Registry (ATSDR) personnel.
Gill was pleased with the discussion that followed the presentations, telling the presenters, "We appreciated your time, and I’m glad it stimulated some interesting conversation. Mines are an obvious challenge and priority here in the West, so your research is appreciated."
The SRP-EPA Seminar Series is designed to bring together the scientific strengths of SRP researchers with the research needs of EPA Remedial Project Managers in the Pacific Southwest. Each topic is presented as a Live at 9 seminar at Region 9 headquarters in San Francisco, followed by an international web seminar sponsored by NIEHS and broadcast via the EPA Clean-Up Information (CLU-IN) website.
Loh and Root reprised their live seminar over CLU-IN on Tuesday, Sept 3, 2013, 1-3pm EST. Archived Webinar .
