Abstract

Many marine bays have been polluted by many pollutants, and identifying the major pollution sources is essential to pollution control. This paper analyzed the distribution and pollution source of Cd in Jiaozhou Bay in 1988. Results showed that Cd contents in surface waters in Jiaozhou Bay in April, July and October 1988 were 0.09-0.12 μg L-1, 0.10-1.07 μg L-1 and 0.03-0.040 μg L-1, respectively. This bay had been slight contaminated by Cd in 1988. The major sources of Cd were river flow, marine current, and atmospheric deposition, whose source strengths were 1.07 μg L-1, 0.12 μg L-1 and 0.04 μg L-1, respectively. River flow was the major Cd source in 1988 since a big part of Cd generated by human activities were washed to and delivered by river flow, and discharged to marine bay finally. Finally, a block diagram model was provided to described these three input paths via land, ocean and atmosphere.
