Abstract

The purpose of this study was to determine the quality of the aquatic environment and the content of heavy metals, sediment, fish, and shellfish around the bauxite mining area. The main question is whether bauxite mining activities affect the quality of the surrounding waters. Further research needs to be carried out at the exact location during non-active mining activities as a comparison. Using the Atomic Absorption Spectroscopy (AAS) method, a field survey and heavy metal analysis are conducted. The results showed that the physicochemical properties of the water were categorized as polluted and unfit for fish farming. Five parameters, Cadmium (Cd), Timbal (Pb), Aluminum (Al), Nickel (Ni), and DO (dissolved oxygen), do not meet the quality standards of fish culture water and metal content in fish and shellfish bodies
