- W1838884098 abstract "The water quality of the Balok River is believed has been deteriorated by anthropogenic impact as a result of the industrial activities in Gebeng Industrial area. This study was conducted to assess the pollution level of the river based on the metal concentrations deposited in the surface river sediment and aslo to evaluate the harm of the studied metals to the water body. The samples of surface river sediment were collected at ten sampling stations that evenly distributed along the river. The sampling technique and sample treatment were done based on the standard procedures as generally applied by other researchers. The total content of Cd, Cr, Cu, Mn, Ni, Pb, and Zn were analyzed by using ICP-OES after an acid extraction with microwave digester. Their mean concentrations (mg/kg) of the respective studied elements are 0.5, 41.9, 24.2, 155.7, 17.3 30.3 and 152.1. Four pollution indices were used to assess the quality of the river including the contamination factor (CF), enrichment factor (EF), pollution load index (PLI) and potential ecological risk index method (PERI). The enrichment level of the studied metals were found in decreasing order as Pb > Zn > Ni > Cr > Cd > Mn > Cu. The potential ecological risk indices of the metals to the water body of the river were observed as Cd > Pb > Cu > Cr > Zn. The results of the pollution indexes confirmed that the surface sediment of the river was moderately polluted with the studied metals and Cd is the only metal that potentially to pose the ecological risk to the water body of the studied river." @default.
