Abstract

Trace metal contamination of marine environments can be determined by measuring trace metalconcentration in sediments, water or biota. Biomonitor organisms have the advantages over othermeasurements that they concentrate the portion of metals that are in a biologically available form, and thisportion which is usually of interest when assessments is being made of trace metal contamination.Correspondingly, whole tissue trace metal concentrations of 4 metals in common Jakarta Bay benthic species(polychaetes, molluscs, crustaceans) from contaminated locations were measured. The mean concentrationfor Cu was 17.5 ± 21.8 μg g-1 dw in polychaetes, 11.9 ± 8.8 μg g-1 dw in molluscs, and 12.2 ± 5.5 μg g-1 dw incrustaceans. The mean concentration for Cr was 172.8 ± 262.5 μg g-1 dw in polychaetes, 31.8 ± 62.8 μg g-1dw in molluscs, and 28.5 ± 29.0 μg g-1 dw in crustaceans. The mean concentration for Zn was 152.4 ± 76.4μg g-1 dw in polychaetes, 132.0 ± 106.3 μg g-1 dw in molluscs, and 515.8 ± 503.5 μg g-1 dw in crustaceans.The mean concentration for Pb was 6.3 ± 13.6 μg g-1 dw in polychaetes and was 2.0 ± 4.5 μg g-1 dw inmolluscs. The study provides significant contribution to confirm the content of heavy metal in each commonbenthic species inhabits coastal Jakarta Bay.

Abstract

Alteration of land is continuing to increase inorganic matter to marine ecosystems and reduce marine biodiversity. Therefore, we investigated the interplay among land use and heavy metal (Cr, Cu, Pb, Zn) inputs from 8 rivers of Jakarta Bay to the benthic biodiversity. At current time, land uses surrounding Jakarta Bay are fulfilled with industrial activity, settlement, and agriculture. Total concentration of Cr, Cu, Pb, and Zn were determined using the Atomic Absorption Spectrometry in order to assess and compare contamination levels among land use types. Results showed that the average concentrations of heavy metals in sediment were generally higher in river-mouth received water from industrial than those in agriculture. Those land use related metal pattern were also reflected in the benthos diversity. Macrobenthic community diversity decreased when inputs of organic matter increased. Decreases in macrobenthic diversity were mainly linked to an increasing abundance of species with specific functional traits, specifically deposit–feeding polychaetes. Our finding confirmed that land use in the form of industrial areas were potential to produce toxic material to ecosystems. Therefore, we recommend that the development need to consider the allocation of physical infrastructure particularly near waterways.

Abstract

Jakarta Bay is located at the north coast of Jakarta bordered by 106 03'00'' Longitude and 6 10'30'' Latitude. Administratively bordered by Bekasi Regency on the east and Tangerang Regency on the west. There are  13 -19 rivers flow to the bay with 2050 industries  that produce hazardous waste, including heavy metals. Metal concentrations in surface sediments and their spatial distributions have increased, recently. Concentration of Pb during 10 years period increase from 23.3 mg kg-1 to 118.2 mg kg-1. The objectives of this study is to know the distribution of Chromium (Cr), Copper (Cu), Lead (Pb), and Zinc (Zn) of Jakarta Bay, Indonesia and their geochemical partition in marine sediments that are bound to “Exchangeable Fraction”, “Reducible Fraction”, “Fe-Mn Oxide Fraction”, “Oxidize able Fraction”, and “Residual Fraction”. The result showed that the concentration of heavy metals in the sediments in most locations were above the Canadian Standard for Contaminated sediments. Concentration of Cr ranged from 48.68—292.09 ppm, Cu ranged between 18.62—151.82 ppm, Pb ranged from 39.7—303.42 ppm, and Zn ranged between 165.83—487.69 ppm. Standard for Cr, Cu, Pb, and Zn are 22 ppm, 30 ppm, 25 ppm, and 60 ppm, respectively. Percent fraction of Cr in labile fraction (F1, F2, and F3) ranged from 30-60 %, while for Cu, its percent fraction mostly bound to lithogenic fraction as much as 38–78%.  Percent of labile fraction of Pb ranged from 22-54 %, while for Zn as much as 15-72%.  These meant that not only Cr but also Pb and Zn were possible to be easily released in the environment as bioavailable metals for biota, especially, benthic invertebrates.
