铬是一种主要的环境污染物,在环境调查和环境监测中被列为必测项目之一。近年来,海湾、沿海等海域铬的研究工作比较活跃,引起国内外海洋化学工作者的日益重视。作为广东沿海环境质量评价研究课题的一个组成部分,我们对粤东沿海海区分别进行了夏季(1980年7月)、春季(1980年4月)和秋季(1981年10月)海水总铬含量的三次考察。初步查清了总铬在这一海区的分布特征及其季节变化,并从计统学方面,对总铬与某些海洋环境因素之间的关系进行了讨论。
Chromium is a major environmental pollutant and has been listed as a must in environmental surveys and environmental monitoring. In recent years, research work on chromium in the gulf, coastal areas and other areas has been relatively active, arousing increasing attention from marine chemical workers at home and abroad. As an integral part of the research project on environmental quality assessment of coastal areas in Guangdong, we carried out the study on the total chromium content of seawater in the coastal areas of eastern Guangdong in summer (July 1980), spring (April 1980) and autumn (October 1981) respectively Three visits. The distributive characteristics and seasonal variations of total chromium in the sea area have been preliminarily identified, and the relationship between total chromium and some marine environmental factors has been discussed from the aspect of geomorphology.
