| Popis: | There have been many studies on the pollution status of Banjir Kanal Barat (BKB) River; however, many of them are limited to the concentration of metals in the river water and their biodiversity of water biota, and partial analysis. The study aims to analyse the metal concentration in BKB river sediment, its toxic to water biota and the effect on the abundance and diversity of macrozoobenthos. The evaluation of pollution status is conducted with three components integrated approach. The sediments were collected from three sampling stations with three replications. While the community observation included abundance, diversity, evenness and dominance of macrozoobenthos. Toxicity testing had been carried out to observe the inhibition of the growth of Chlorella sp algae in pore water sediments and failure reburial of blood clams into the substrate/sediment. While the evaluation of pollution status was conducted in an integrated three components approach. The results showed that the concentrations of various metals in the sediment were varied. The concentration of metals in sediments were still within natural limits and identical to the reference station that was not polluted. 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. |
