摘　　要：于2010年春、夏、秋季对钦州湾海域进行调查,对表层海水中重金属Hg、Cr、Pb和Cd进行了分析。结果表明,钦州湾表层海水中溶解态重金属的浓度高值区均分布在近岸江口和港口区,受人类活动影响比较明显。钦州湾表层海水重金属含量均未超过国家一类海水水质标准,水质状况良好。During the investigation in Qinzhou Bay in the spring, summer and autumn of 2010, surface seawater samples were taken for heavy metals （Hg, Cr, Pb and Cd） analysis. The study result indicated that high values of dis- solved heavy metals were distributed in the river mouth and docklands, which was obviously an influence of human activi- ties. The concentrations of heavy metals in the surface seawaters did not exceed those of the First - Classed Seawater Qual- ity Standard of China, which indicated a pretty good water quality in Qinzhou Bay.
