Abstract

Abstract

Estuaries are the primary gates for pollutants entering into sea. It is important to analyze the distribution and assess the pollution of sediments, because pollutants can settle into the sediments and repeat release after flowing into sea. This paper aids to provide a scientific basis for ocean remediation and marine environmental protecting project by the way of finding out the pollution characters and assessing the polluted degree. The results show the following. Condemnation content has a trend of higher from top to bottom in space, while sulfide and total nitrogen are main pollutants. Sediments in estuaries are at a level of clean-cleaner based on synthetic index(p),while they are at the level of cleaner to light-polluted in profiles. At the same time, sediments in estuaries are at a level of low to lower-moderate based on potential ecological risk index(ir),while they are at a level of low to moderate in profiles.
