摘要
Based on the investigation data of water area in Jiaozhou Bay in April and August of 1981,Cr content and its surface horizontal distribution in water area of Jiaozhou Bay were studied. Research results showed that Cr content in the water body of Jiaozhou Bay was between 0. 18 and 32.32μg/L,corresponding with national class-one seawater quality standard( 50. 00μg/L). The water area of Jiaozhou Bay was not polluted by any Cr. In April,Cr content was higher in northeast water area of Jiaozhou Bay and lower in southern coastal waters. In August,Cr content was lower in whole Jiaozhou Bay. Cr in water area of Jiaozhou Bay was mainly from river,which was between 1. 85 and 32. 32 μg/L. It showed that Cr content of river transportation was lower,and river was not polluted by Cr,and water quality was all very clean from river to all marine coastal waters and gulf waters.
