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

Highlights

Development activities including mining, land clearing, and settlements must be responsible for ecosystem damage and environmental degradation
Considering that the waters around Los Senggarang Island are a source of livelihood for local fishers and a source of water supply for grouper aquaculture, it is necessary to consider maintaining the quality of the aquatic environment
The content of heavy metals in the bodies of fish and shellfish has indicated that the distribution of heavy metals contaminates the aquatic organisms around the waters of the grouper cultivation location on Los Senggarang Island

Summary

Introduction

Development activities including mining, land clearing, and settlements must be responsible for ecosystem damage and environmental degradation. Bauxite mining has affected the quality of the coastal waters of Tanjungpinang City. Considering that the waters around Los Senggarang Island are a source of livelihood for local fishers and a source of water supply for grouper aquaculture, it is necessary to consider maintaining the quality of the aquatic environment. The main findings of this study indicate that the pattern of bauxite mining activity has affected the decline in the quality of the surrounding aquatic environment. The release of tailings mud carried by rainwater into coastal waters, especially after heavy rains, causes changes in the quality of fish farming waters.
