上海海岸带沉积物地球化学基准值特征.

Based on the regional geochemical results obtained from the multi-purpose regional geochemical survey project in the offshore marine areas of Shanghai in 2007, according to the basic concepts and requirements of element geochemical reference values, the geochemical baseline of sediments of the whole region, different sediment types and different sedimentary units are calculated respectively, and compared with the geochemical baselines of shallow sea sediments in China, the China soil geochemical baselines, the geochemical baselines of soil of the Yangtze river basin and the Yangtze river delta. The establishment of geochemical baseline of sediments in the Yangtze Estuary and offshore marine areas provides an important geochemical basis for the comparison of sediment environment in large estuaries, the formulation of regional sediment environmental quality standards, and the evaluation of coastal environmental pollution.
