Abstract :
This paper analyzed the content, distribution and source of Cr in surface waters in Jiaozhou Bay in 1982. Results showed that Cr content in April, June, July and October, ranged from 0.81-2.11μg.L-1, 0.33-9.67μg.L-1, 1.02-9.62μg.L-1 and 0.24-1.35μg.L-1, respectively, complied with Grade I (50.00μg.L-1) in Sea water quality standard (GB 3097-1997) of China, indicating that Jiaozhou Bay was very lightly polluted by Cr in 1982. Both point and non-point sources were major sources of Cr in this bay, increasing repetitive use rate of Cr and reducing emission loads of Cr were the major pollution control and prevention countermeasures in Jiaozhou Bay.
