【 摘 要 】

Trace metals (Ag, Al, As, Cd, Co, Cr, Cs, Cu, Fe, Mn, Ni, Pb, Se, Sr, Tl, U, V and Zn) in PM₁₀ were measured at 10 different sites in the surrounding areas of Tummalapalle Uranium Mining (India). The PM₁₀ samples were collected on glass fiber/EPM 2000 filter using high volume air samplers in 10 different sampling sites during November–2010 to February–2012. Trace metals in PM₁₀ were analyzed using Inductively Coupled Plasma Mass Spectrometer (ICP–MS). The observed trace metal concentrations varied from 0.01 to 2 640 ng/m³. It was found that metals associated with crustal sources like Al and Fe were in higher concentrations. The elements Tl, U, Cs and Co were found to be in very low concentrations. Obtained trace metal data in PM₁₀ were subjected to statistical analyses using correlation matrices and factor analysis to examine the interrelationship between the investigated trace elements and possible source identification of the elements. Enrichment factors of trace metals were also determined to determine the anthropogenic contribution to ambient PM₁₀. The daily intake of analyzed trace metals by the adult population in the surrounding of Tummalapalle Uranium mining (30 km radial distance) was estimated and it was found to be in the range of 1 to 13 401 ng/day through the inhalation route.
