ABSTRACT
This report presents the results of ambient air monitoring of metals in total suspended
particulate (TSP) matter performed during the 1992-1993 austral summer at McMurdo Station,
Antarctica. Seven samples of TSP were collected from three different locations and analyzed for
arsenic, beryllium, cadmium, chromium, lead, nickel, and mercury. Critical-flow high-volume air
samplers with a sample flow rate of approximately 1.1 m3/minute were used to collect the
particulate matter on quartz fiber filters for subsequent laboratory analysis. Sampling site
selection, sampling procedures, and quality assurance procedures used were consistent with U.S.
Environmental Protection Agency guidance for local ambient air quality networks. The data
indicate that McMurdo operations have a measurable impact on the qualitative toxic metals
composition of suspended particulate matter in the ambient air; however a definitive quantitative
impact could not be concluded. The levels measured are well below the U.S. National Ambient
Air Quality Standards and American Conference of Governmental Industrial Hygienists worker
exposure levels. Lead was the most prevalent of the seven toxic metals and was detected in all
samples at concentrations ranging from 1.4 ng/m3 to 38 ng/m3. Data on the concentration of
eleven other metal species are presented. Most notable was the relatively high abundance of
titanium and copper, which were detectable at levels up to 2,100 ng/m3 and 230 ng/m3,
respectively.iii
