Final Progress Reports

Year:   2014  2009  2004 

The Hazard Identification Research Support Core continues to be the focal point for all metal analyses for the Superfund Research Program and many other federally supported projects at the University of Arizona (UA). The Analytic Section now is performing metal analyses on biomedical samples (blood, urine, tissue, cell culture), environmental water samples (for SRP, colleagues in the US-Mexico Binational Center – both US and Mexico, collaboration with Dartmouth SRP, environmental/biomedical projects with the University's Water and Environmental Sustainability Program, and projects associated with UA's NIEHS-sponsored Toxicology Center). Nearly 12,000 analyses were performed by this Core, both total metal analysis and for chemical speciation (e.g., arsenite, arsenate, monomethyl As(III), etc). Of particular note are the broad spectrum of metal analyses being performed on air particulate samples collected from mining sites and air samples around Tucson - these analyses are being used to demonstrate the program's emphasis of dust as a vector for exposure to hazardous waste in the arid Southwest. This centralized source for metal analyses facilitates the research aims of seven of nine current UA-SRP research projects and eight of the nine research projects in the program's renewal application. The Hazard Identification Core also was used by UA Superfund investigators as a source of analytical support for NIEHS, EPA, NSF, and DOE grant applications and ongoing studies. This Core has helped to leverage the UA SRP program through these agencies. The Arizona Laboratory for Emerging Contaminants also was launched in 2009. It is supported by the SRP, funds from the Water and Environmental Sustainability Program, and charges to the investigators for the analyses. This new analytical Center is providing a broad range of LC and GC analyses for the program's SRP investigators as well as environmental research across the University and the State.
