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.

Abstract

In the mangrovesof Blanakan, Indonesia, silvofishery practices may play arole in maintaining the environmental quality of ponds. Mangroves are known as pollutant traps since their root systems absorb and accumulate materials. Heavy metals are pollutants that often contaminate aquatic environment like ponds. The bioconcentration factor can be used to evaluate the content of heavy metals in organisms, while the translocation factor can be used to measure the amount of heavy metals transferred form one organ to another. The aim of this study was to determine the bioconcentration factor and the translocation factor of heavy metals (Pb, Cu,andZn) in mangrovetrees (Avicennia and Rhizopora) at the Blanakan ponds. Samples of mangrove trees from 3 stations, were cut using a knife, and samples of sediments were collected using Ekman Bottom Grab sampler. Samples were then prepared for heavy metal content analysis using the Shimadzu 6300 atomic absorption spectrophotometer. The bioconcentration and translocation factorswere calculated using formulas; the bioconcentration factor was calculated as the content of heavy metals in trees divided by the content of heavy metals in sediments. Results showed that the bioconcentration factor of Cu was higher than 1 in the roots, stems and leaves of Avicennia trees and of Zn was higher than 1 in the roots of Rhizopora trees at station 1. Translocation factors higher than 1 were mostly found in Avicennia (Cu) and Rhizopora (Pb) trees. Mangrove trees with translocation values of greater than 1 for one or more heavy metals can be considered as strong accumulators of the corresponding metals.

Abstract

Study about the effect of hydrocarbon-polluted seawater on the cell density of microalgae Scenedesmus vacuolatus has been done. Hydrocarbon pollution derived from oil in the sea can inhibit photosynthesis process of microalgaes. This might impact the density of microalgae cells. The purposes of this study are to determine the effect of the concentration of hydrocarbon-polluted seawater on the density of Scenedesmus vacuolatus microalgae cells and to determine the optimum treatment to reduce total petroleum hydrocarbons (TPH) levels. Sampling of hydrocarbon-polluted seawater was taken at Kali Adem port, Jakarta. The treatment done in this research used Walne medium with the addition of 25% hydrocarbon-polluted seawater (A), 50% (B), 75% (C), and 100% (D). Control is Walne medium with sterile seawater that was not from the Kali Adem port. The results showed the highest average density of Scenedesmus vacuolatus cells was in the control sample. This can be seen from the results of the average cell density at peak time of 29.48 x 105 cells / mL, as well as the log phase length of Scenedesmus vacuolatus. Measurement of TPH levels showed decreases of TPH in all treatments. The optimum treatment to reduce TPH levels is on treatment B with reduction percentage of 70.62%. Key words: Kali Adem port, Scenedesmus vacuolatus, total petroleum hydrocarbon (TPH), Walne medium

Abstract

The Garapan river mouth forms part of the Tanjung Pasir coastal area. This region receives materials not only from coastal waters but also from domestic sewage and industrial wastewater that contains heavy metals such as Cu, Pb, and Zn. On the contrary, the Cibungur river mouth in the different coastal area, receives relatively lower amounts of domestic sewage and industrial wastewater. The objective of this study was to determine the Cu, Pb, and Zn content in the coastal sediment as well as the levels of A.indica and their relationship with water quality parameters. Samples were collected from four stations located in the Garapan and Cibungur river mouths and were analyzed for metal content using atomic absorption spectrometry Shimadzu 6300. Samples of A. indica found in the field are categorized into three diferent size classes. It is because size related to heavy metal accumulation. Results showed that bioconcentration factor (BCF) values were Zn>Cu>Pb in both locations. Small size A. indica tends to have higher values of BCF for Cu and Zn compared to medium and larger sized samples. Furthermore, the BCF values of Cu, Pb, and Zn in A. indica were higher when the sediment had a lower concentration of organic matter.
