关于Banjir Kanal Barat河(BKB)污染状况的研究较多;然而，其中许多都局限于对河水中金属的浓度及其对水生物群多样性的影响和局部分析。本研究旨在分析BKB河沉积物中金属的浓度、对水生生物的毒性以及对大型底栖动物丰度和多样性的影响。采用三分量综合评价法对污染状况进行评价。沉积物从三个采样站收集，重复三次。大型底栖动物群落表现为丰度、多样性、均匀度和优势度。通过毒性试验观察了小球藻sp藻在孔隙水沉积物中的生长抑制作用和血蛤在基质/沉积物中的重埋失败。污染状况评价采用三要素综合评价方法。结果表明，沉积物中各种金属的浓度是不同的。沉积物中的金属浓度仍在自然限度内，与未受污染的参考站相同。 The types of macrozoobenthos were found about nine genera with varying in abundance, diversity index, evenness index, and dominance index. The abundance, diversity index, evenness index, dominance index of macrozoobenthos at all stations were still identical with reference stations, which known was not polluted. Although pore water sediments and sediments from various stations caused inhibition of the growth of Chlorella sp and the failure reburial of blood clams, statistically analysis was not significantly different from the reference station. Overall it can be stated that the sediment quality in those three stations was still excellent, however, they need to be maintained.
