| In this paper, the characteristics and sources of trace elements in rainwater were discussed by analyzing the chemical composition of the rainwater collected in the northern part of Huangshan scenic spot. It was conclude that the content of trace elements showing obvious seasonal variation, and was mainly affected by rainfall, pH value, wind direction and dissolved organic matters. According to source analysis and contribution estimation, the content of Mn, Cu, Pb, Cd, Ni and Co in rainwater were caused by coal and traffic pollution whose contribution were both over 98%. Soil source and anthropogenic source contributed 76.9% and 23.1% of Fe, and 22.8% and 77.2% of Ti, respectively. The ocean source and anthropogenic source contributed 28.3% and 70.5% of Sr to the rainwater, respectively. |
