摘    要:以浙江沿海水域为研究区域,在系统地测定水体与沉积物中有机污染物种类的基础上,研究了表层沉积物中有机污染物的积累与沉积环境、沉积物矿物组成和排放环境因素之间的相互关系.结果显示,沿海水体和表层沉积物中主要存在的有机污染物有石油烷烃类化合物、邻苯二甲酸酯化合物、有机硅氧链类化合物、氯代苯酚类、苯醚类和胺类化合物等6大类,它们在表层沉积物中的积累强度呈现出河口大于沿岸大于强潮汐河沉积环境的趋势,但在相同沉积环境的沉积物中有机污染物的积累强度存在一定的差异,这说明有机污染物在沿海沉积物中的积累除与沉积环境有关外,还与区域有机污染物的排放特点有关.

关 键 词:有机污染物  沿海沉积环境  积累差异性

Abstract:Based on the systematic analytical data on the organic pollutants in seawater and surface sediments from Zhejiang coastal zone, the relationships between accumulation of the organic pollutants in surficial sediments and environment factors such as sedimentary environment, mineral composition and sources were studied. The results show that the main organic pollutants in the coastal water and surficial sediments are petroleum alkanes, o-benzenedicarbonic acid ester, organic silicon chain, phenol-chloride, phenyl ether and amine. Their accumulative amount in surficial sediments has a tendency towards the estuary sedimentary environment bemg greater than coastal sedimentary environment bemg greater than stronger tidal river sedimentary environment. The differences of the organic pollutant accumulation in the sediments in same sedimentary environment were known, which indicates that the accumulation of organic pollutants in coastal sediments was related not only to sedimentary environment, but also to the regional sources of organic pollutants.
Keywords:organic pollutant  coastal depositional environment  accumulation difference
