用AET法建立海洋沉积物环境质量基准

AET APPROACH TO DEVELOPING MARINE SEDIMENT ENVIRONMENTAL QUALITY CRITERIA

海洋沉积物环境质量基准的建立是制定其质量管理环境标准的前提.国外近20年的研究已逐步建立起一系列有效的沉积物环境质量确定方法.这些方法各有所长,可以互为补充,其中表观效应阈值法(AET法)正在受到重点关注.这种方法结合了现场实际与实验室确认两方面的大量可靠数据,综合判定沉积物的质量阈值,有很大的发展潜力.本文对此方法进行了综合讨论.

Developing marine sediment environmental quality criteria is the prerequisite for formulating its environmental quality standard. About 20 years'overseas study has established a series of effective approaches in this field. Each of the approaches has its own advantage and can be supplemental to each other. The Apparent Effects Threshold (AET) method, which is considered as possessing potentialities, is an approach through which comprehensive sediment quality threshold is determined by processing the combination of large quantity in situ data and laboratory data. The principles used and the techniques and relevant to AET method is introduced and discussed in this paper.
