Atmospheric Deposition of Metals in TSP of Guiyang, PR China.
Total concentrations and speciation of metals had been studied in TSP of Guiyang from April 2006 and January 2007, PR China. The average concentration ranged from 14.48 ng m(-3) for Cd to 1,161.45 ng m(-3) for Zn. The concentrations of Cd, Cr, Pb and Zn were significantly higher during winter than those at other seasons. The environmentally mobile fractions of Cd and Zn were the highest in the three stages. The highest proportion of Pb was the fraction that bound to carbonate and oxide. Cr and Cu were clearly restricted to the fraction that bound to silicate and organic matter.
