Abstract

Abstract

Based on the systematic analy tical 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-benzenedicar-bonic acid ester, organic silicon chain, phenol-chloride, phenylether 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.
