Abstract

This paper analyzed the contents, distributions and pollution sources of As in Jiaozhou Bay waters in 1983. Results showed As contents ranged from 0.19-4.89 g L-1,in the whole year, and were lower than Class I for As (20.00 g L-1) in National Standard of China for Seawater Quality (GB3097-1997). There were high value regions in coastal waters in the northeast, east and southwest of the bay, as well as waters outside the bay mouth. The major sources of As were overland flow marine current and stream flow, whose source strengths were 2.93-4.89 g L-1, 1.59-4.30 g L-1, 1.63-3.33 g L-1, respectively. The variation ranges of the source strengths of the three pollution sources in different seasons ranged from 1.70-1.96 g L-1, indicated that the inputs of As from different sources in this waters was sustained and stable. Hence, in addition to the anthropogenic factors, the natural sources from marine current should be taken into account.
