Abstract

Jakarta Bay waters contaminated with heavy metals, so that the waters of the Thousand Islands are also potentially contaminated with heavy metals. The purpose of this study were to determine the condition of the water quality on the Panggang Island and Karya Island, analyze contamination of heavy metals (Cadmium and Lead) in water, sediments and Prickly Pen Shell and then the correlation. Based on Ministry of Environment decree No. 51/2004, water quality in the Panggang Island and Karya Island tend toward to low category. Cadmium and lead concentration in the water on October exceed the quality standards. In the sediment on July and October at Karya Island, concentration of cadmium were exceed the quality standar by RNO. On the other hand, cadmium and lead concentration on Prickly Pen Shell still below standard quality from decree of Director General of POM RI No. 03725. We found highest positive correlation were found between cadmium and lead accumulation in the water and on the Prickly Pen Shell, then positive correlation between cadmium and lead in the water and in the sediment. For the heavy metal contamination, we found contamination of cadmium correlation were higher than lead contamination.

Abstract

Seribu Islands located in the north of Jakarta Bay; it is potentially polluted by heavy metal such as Cd and Pb. The aims of this study is to prove contamination presumption, by analyzing and determine correlation Cd and Pb concentration in the sediment, in the water and on milkfish Chanos chanos cultured in this area. On this study, we collected water quality data (pH, temperature, dissolve oxygen and salinity) and heavy metals contamination (Cd and Pb) in the sediment, in the water and on milkfish.  We compare collected data with quality standar and correlate heavy metal concentration between in the water and in the sediment; in the water and on milkfish organ; and, in the sediment and on milkfish organ.  In general, water quality is sufficient enough to support the life of farmed milkfish. Cd and Pb contamination level in the water lied below the quality standard of Ministry of Environment decree No. 51/2004 in the last April and July. However, the contamination exceeds the standard in the last October. The contamination in sediment lied below RNO (1981), EPA (1999) and IACD/CEDA (1997). Gills, viscera and the meat of the milkfish are contaminated with Cd and Pb, yet, still lied below the quality standard of Ministry of Environment Decree No. 51/2004. The results showed that farmed milkfish in Thousand Islands are safe to eat. We also found that the correlation of Cd and Pb contamination between water and sediment is positive. The correlation of Cd is much higher than Pb. The correlation of Cd between water and viscera as well as between sediment and viscera are the most closely related than any other organ.  Keywords: contamination, Cd, farming, milkfish, Pb, Seribu Islands
