Abstract

A preliminary study on the response of amphipod exposed to contaminated sediments of Jakarta Bay was carried out in October 2009. The objective of the study was to determine the mortality rate of amphipod in response to exposure of contaminated sediments. Seven sediment samples were taken from the bay, i.e, reference site (St. A), and six-contaminated sites (St. B3, B5, C3, C5, D3, and D5). Amphipod (Grandidierella sp.) was collected from reference site. The study showed that average of mortality rate of amphipod ranged between 50.0 and 76.3% at contaminated sediments and 38.3% at reference sediments. There was significant difference on mortality rate of amphipod exposed to sediments of reference site and that of contaminated sites. The mortality of Grandidierella sp. was not strongly correlated with the concentration of Pb and Cu in contaminated sediments. The critical mortality factor of amphipod in this study might be due to variation in grain size of sediments and short period of acclimatization.

Abstract

Indication of accumulation of heavy metal in sediments will lead to problem for shore and sea ecosystems, biota living in that area and human’s health. The research is aiming to analyse the toxicity of sediment from thirty one locations in Jakarta Bay using Perna Viridis. High amount in larval abnormality found in sediments from the area near mainland and estuary are an indication of high influence of waste from anthropogenic activities from Jakarta mainland. These areas are down stream of Cengkareng Drain, Kamal River, Grogol River and Cakung River, area around sea transportation and North Jakarta Integrated Industrial Area. Sediment of Jakarta Bay, especially coming from estuary area and near to the land area causes an increase in green mussel larval abnormality. This indicates the high of waste influence from anthropogenic activity from Jakarta land area.

Abstract

Sediment of 16 sites in the Kelabat Bay were monitored for metal contamination and toxicity in 2006. Two patterns of metal contaminants distribution in the sediment were observed. Higher concentrations of lead and copper were found in March than those in July, and so was in the inner bay than those observed in the outer bay, while different pattern was observed for cadmium concentration. The highest lead concentrations were observed at site 7 (inner bay) both in March and July. Although elevated levels of cadmium, lead and copper were observed in sediments, they were still in the tolerable level for marine life. Sediment of the bay was also evaluated for its toxicity using marine phytoplankton, Chaetoceros gracilis and sea urchin, Tripneustes gratila. Results of the tests reveal that no toxic effects of sediment to the growth of phytoplankton were observed, but to sea urchin fertilization of the sediment may have toxic effect.
