Abstract

Based on investigation dada on Cr in May and August 1979 in Jiaozhou Bay, we analyzed the content, distribution of Cr. Results showed that Cr contents in 1984 in surface waters were 0.10-112.30 g L-1 and were meeting Grade I (50 g L-1), II (100 g L-1) and III (200 g L-1) in National Sea Water Quality Standard (GB 3097-1997). We found that river was the major source of Cr, and the source strength could be as high as 112.30 g L-1. In April, Cr contents were relative high in coastal waters in the northeast of the bay yet were relative low in coastal waters in the south of the bay. In August, Cr contents were relative low inside and outside the bay. In generally, this bay had been moderately polluted by Cr, and the source-control/reduction of Cr was necessary.
