Distribution of Heavy Metal Lead (Pb) in Water and Plankton on Floating Net Cage Area with Different Density at Cirata Reservoir, West Java

Cirata Reservoir mostly functions as a Hydroelectric Power Plant (PLTA) and the location of fish farming with the floating cage system (KJA). Utilization of reservoirs for fish culture in Cirata Reservoir has exceeded the capacity determined by the government. This causes changes in water quality in the waters of the Cirata Reservoir and affects the concentration of heavy metal lead in the waters. The purpose of this study was to determine the distribution of heavy metal lead (Pb) that exist in the KJA with different densities in the Cirata Reservoir. This research was conducted on 3 November-8 December 2019 at Cirata Reservoir with sampling stations in Jangari, Maleber and Patokbeusi. The method used in this research is purposive sampling. The results of the physical-chemical parameter research show that the water temperature at the three stations ranges from 31.9oC-34.5oC, air temperature 27oC-32oC, transparency 53.5-76 cm, pH 6.87-7.67, CO2 8,4-16.8 mg/L, BOD 1.1-20.5 mg/L and DO 5.83-9.72 mg/L. The results of Pb measurements in water ranges from 0,001 to 0,029 mg/L. Pb measurements in plankton ranges from 0.001 to 0.039 mg/L. Pb bioconcentration factor values range from 1.27 - 2.40. These results indicate that aquatic organisms in the Cirata Reservoir can accumulate metals in their bodies.

Introduction: Heavy metal contamination of aquatic ecosystems has been a serious concern throughout the world for many decades, and has caused devastating effects on aquatic organisms. Objective: To evaluate the levels of Cu, Zn, Fe, Pb and Cd in the kidneys of scaly (T. zillii, M. rume and R. ocellatus) and non-scaly (C. gariepinus, Ch. nigrodigitatus and S. filamentosus) fishes in Epe lagoon, Nigeria to understanding the bioaccumulation potential of the kidney relative to other organs in fish that have previously been reported in literature. Methods: We studied concentrations of copper (Cu), iron (Fe), zinc (Zn), cadmium (Cd) and lead (Pb) in the kidneys of 141 scaly fishes (Mo. rume, R. occellatus, T. zillii) and 134 non-scaly fishes (C. gariepinus, S.filamentosus, Ch. nigrodigitatus) and water samples obtained from Epe Lagoon using Standard Atomic Absorption Spectrometry methods. Results: The kidneys of R. ocellatus had the highest levels of Fe (2,92±0,10) and Cd (0,18±0,03), while that of Ch. nigrodigitatus (2,78±0,02) and T. zillii (0,31±0,02) had the lowest concentration of Fe and Cd respectively. T. zillii and M. rume accumulated Cu and Zn in their kidneys respectively more than the others. There was no significant difference (p<0,05) in mean trace metal concentrations among the scaly and non-scaly fishes. The concentrations of metals in fish specimens were below the FEPA and WHO prescribed maximum allowable limits in food fish. Dissolved oxygen (9,0±0,02) and total alkalinity (24,0±0,01) were above FEPA values (dissolved oxygen: 3,0-5,0mg/L and total alkalinity: 3,05-5,3mg/L). The ranking of heavy metals distribution in the water body was Cu (4,70)>Fe (0,72)>Zn (0,13)>Pb (0,007)>Cd (0,006). Bioconcentration factor of Zn was generally high in all species. Conclusion: Close monitoring of these metals in the fishes and the lagoon is important to ensure the safety of fish consumers in the area.

Pollution prevention must be carried out in the upstream, middle and downstream parts. One of the Citarum watersheds located in the middle part is the Cirata reservoir. Pollution in the Cirata reservoir does not only originate from the reservoir environment, but also from rivers that flow into the Cirata reservoir. Cirata Reservoir besides being a Hydroelectric Power Plant (PLTA) unit, this reservoir is also used by the community for fish farming in the Floating Net Pool (KJA) technique. This study aims to determine the most dominant pollutants contaminating the Cirata reservoir. Test of river and reservoir water quality is carried out with the help of lab tests by Labkesda. The research data was obtained by obtaining clean water quality test data from several 3 estuary points of the river flow to the Cirata reservoir and 4 centers of Cirata reservoir number of 40 samples. Data processing techniques are carried out using data mining, namely Exploratory Data Analysis. The lab parameter test results, which are compared with the Permenkes No. 32 Year 2017 standard, show that the majority of the physical and chemical quality parameters of the Citarum River which empties into the Cirata Reservoir are still within the required threshold. Most river and reservoir water samples have water quality that qualifies as clean water. Five samples (12.5%) in turbidity parameters and 1 sample (2.5%) in color samples did not qualify as clean water. This is possible because the sampling is too close to the mainland. Temperature parameters of 20 samples (50%) do not qualify as clean water is possible because of the lag time of sampling. The results of the analysis showed that the distance of pollutant sources, the amount of pollutant sources, and environmental conditions around the sampling significantly with temperature, TDS, turbidity, color, pH, nitrogen, iron, hardness, manganese, fluoride, and cyanide.

The article provides information on statistical approaches to identify the dominant factors that influenced the water quality in the Bureyskoye reservoir after a large landslide in December 2018 blocked access to a hydroelectric power plant. To restore the hydrological regime, blasting operations were carried out using trinitrotoluene and hexogen. The main indicators of water quality were volatile organic matters and elemental composition that varied along different banks above and below the landslide body and under the influence of explosives. In water samples from the artificial canal after the restoration of the reservoir flow, the content of Fe, Mn, Al, Cu and Zn remained at a low level and did not reach the initial values established prior to the blasting operations. However, an increase in the content of Pb by 7 times and Hg by 80 times was noted. The presence of methanol and methylated benzene derivatives in water could stimulate the formation of more toxic methylmercury, posing a risk to aquatic organisms. Correlation analysis was used to process the obtained data which made it possible to differentiate the contributions of natural (landslide, river tsunami) and anthropogenic factors (blasting) to the change in the chemical composition of water in the reservoir.
