With the recent development of society and economy in the cities of Huludao and Jinzhou, Liaoning Province, China, environment and ecosystem problems have become increasingly serious in Jinzhou Bay, China, because of the increasing amount of heavy metal pollutants being discharged. To solve these problems, a water quality model of heavy metals coupled with a 3D hydrodynamic model is constructed to estimate the environmental capacity (EC) and total maximum allocated loads (TMALs) for Zn and Cd of three river catchments in Jinzhou Bay. According to the model, the ECs for Zn and Cd are approximately 17 and 8 tons per month, respectively, if the criterion obtained from HC5 values (fifth percentile of the SSD) is set as the control criterion (8.24 μg/L for Zn and 3.83 μg/L for Cd) in Jinzhou Bay, and the TMALs of the three river catchments are 4 and 1.7 tons per month.
随着中国辽宁省葫芦岛市和锦州市近期社会经济的发展,由于重金属污染物排放量的增加,锦州湾的环境和生态系统问题日益严重。为解决这些问题,构建了一个重金属水质模型,并结合三维水动力模型,以估算锦州湾三个河流集水区锌和镉的环境容量(EC)和总最大分配负荷(TMAL)。根据该模型,如果将从HC5值(物种敏感度分布的第五百分位数)获得的标准作为锦州湾的控制标准(锌为8.24μg/L,镉为3.83μg/L),锌和镉的环境容量分别约为每月17吨和8吨,三个河流集水区的总最大分配负荷分别为每月4吨和1.7吨。
