[email protected] ABSTRACT The pollution of rivers from human activities such as housing, markets, workshops, transportation, land cultiva- tion, and industry has become an issue. The increasing contribution of heavy metals to pollution in rivers has a direct effect on the metal bioaccumulation in fish. Therefore, this study aimed to examine the concentrations of Cd, Cu, and Pb in the waters, sediment, and fish harvested from the Krueng Sabee River, Aceh Province, Indonesia. Furthermore, the water, sediment, and fish samples were collected from six locations representing the upstream and downstream regions of the river.
