平衡分配法评价有毒金属沾污沉积物的应用研究

平衡分配法是近几年在国内开展的用于评价沉积物的一种研究方法，它主要运用平衡分配的原理，从污染物质的结合相入手，找出能够控制污染物质的主要因子，通过分析该主控因子的变化情况，判断沉积物中污染物质对环境的危害程度，该方法在一定程度上解决了传统沉积物质量评价方法不具有时空可比性的弊端。本试验是将平衡分配法评价有毒金属沾污沉积物的研究方法应用于锦州湾地区的沉积物评价，检验该方法的适用条件和可靠性。结果表明，该方法在厌氧沉积环境下具有较好的实用性和科学性，对目前沉积物质量评价是一个较好的补充方法。

Study on quality assessment on sediment contaminated with metals by the equ ilibrium-partitioning (EqP) method

EqP method was applied in recent years in China and mainly to evaluate the quality of sediment, in accordance with the principle of equilibrium partition, proceed with combined phase of pollutants, seek for the controlling factor of pollutants through analyzing the change of controlling factor, confirm the degree of contamination. In the test, application of the EqP method to sedimetn quality assessment in Jinzhou Bay, and check of the conditions and security of the method were done. The results showed that the method is practical for assessment on the toxicity of metals in anaerobic sediments, and it is a good complement of present assessment methods to sediment.
