This research aimed to obtain information about the distribution of the metal content of Pb, Cu and Zn in the sediments both horizontally and vertically, as well as to determine the level of metal pollution in Telaga Tujuh Coastal Waters due to the abandoned tin mining and anthropogenic activity around the area. The average content of heavy metals Pb, Cu, and Zn in the coastal waters of Telaga Tujuh are 60.76 μg/g, 38.24 μg/g and 108.41 μg/g, respectively. Average metal content of Pb, Cu and Zn are different betwean the upper layer (0-1 cm), middle layer (10-11 cm) and lower layer (20-21 cm). The highest metal content were found in the upper layer (0-1 cm), Pb 65.78 μg/g, Cu 49.12 μg/g and Zn 128.69 μg/g, which are related to the current input from anthropogenic activitis. Upper part of the sediment (0-1 cm) are the fastest layer influenced by heavy metal deposition than others coming from anthropogenic activitis around the Telaga Tujuh Coastal Waters.otherKarimunFormer of Tin MiningSediment LayersMetals PbCu and ZnPollution.student Paper Post Degree
