Article Preview

An environmental assessment system was established to analyze and evaluate the pollution status of surface water and sediments of Bohai Rim Area. Considering the requirements of evaluation item completeness and criteria strictness, this paper selected the Multimedia Environmental Goals, Classification Index of Soil Fertility, Organic Index Evaluation Standard and Soil Environmental Quality Standard as the evaluation standards. The results show that for each media, benzo(a)anthracene, benzo(a)pyrene and dibenzo(a,h)anthracene are the major pollutants among PAHs. And for the sediments, the organic matter and total nitrogen reach the level of fertile pollution in the area. The specific organic compounds and heavy metals (including As) are both concentrated in Tianjin, in accordance with the development level of industry of the area.
