【 摘 要 】

Cu is one of the few metals that predominate in water. In addition, Cu potentially pollutes to any aquatic organisms due to bioaccumulation and biomagnification. One of the estuaries that experienced pressure due to the presence of Cu is Jagir River estuary in Surabaya. The objective of this study was to determine Cu metal concentration in the water and sediment of Jagir River estuary. The sample was purposively taken from the estuary area and its surroundings, in general grouped in three locations: station 1 (before entering the estuary), station 2 (inside estuary), and station 3 (flowing beyond the estuary). The results indicated that the concentration of Cu in the water at station 1 was -1 while station 2 and 3 had the same concentration of 0.05 mg L-1. Cu concentration at stations 2 and 3 exceeded the standard limits set by the government. In terms of sediments, Cu concentrations were still below the standard quality limits with an average of 44.73 mg kg-1. Therefore, the water of Jagir River estuary had been already polluted by Cu metal, however Cu concentration in the sediment still meets the criteria of the government.
