利用珠江口外东平海域环境评价资料,对该海域各类沉积物组分中的部份痕量污染元素进行了研究,找出了各沉积物组分中痕量污染元素的分布规律及富集特征,并以《海洋沉积物质量标准（GB18668—2002）》为依据,进行了定量评价。结果表明：痕量污染元素富集主要出现在西部浅水区和东侧航道,明显受河口水动力条件和沿岸人类活动的影响。沉积物中的痕量污染元素的富集,影响因素众多,环境复杂,在研究区大致可归为物源、动能强弱、沉积物性质、理化环境、生物作用等;珠江口外东平海域沉积物环境质量较好,污染较轻,为我国海洋底质Ⅰ、Ⅱ类标准。

Based on the related environmental assessment data of Dongping sea area outside the mouth of Pearl river,the distribution and enrichment characteristics of some metal pollutants in various deposits were analyzed in this paper.Furthermore,the pollutants were quantitatively assessed according to the National Ocean Sediment Quality Standard（GB18668-2002）.The results showed that the enrichment of trace pollution elements occurred in shallow water area at west side and sea lanes at east side,showing the obvious influences of estuarine hydrodynamic condition and human activity at coast.The sedimentary environment quality in Dongping sea area belongs the I and II type standards of China marine substrate.Many factors influenced the enrichment of trace pollution elements,such as sediment resource,hydrodynamics,sediment characteristics,physical and chemical environment,biological activity,etc.
