Investigation of Heavy Metals in River Water, Sediments, and Fish in Krueng Geumpang, Pidie Regency, Aceh Province

Abstract

The environmental problems throughout the world have become a concern, especially regarding environmental pollution. Environmental pollution can be caused by various industrial and daily human activities. The primary objective of this study is to analyse the level of contamination and accumulation of heavy metals such as Pb, Hg, Cu, and Fe distributed by heavy metals in water, sediments, and fish in Geumpang River. The data samples used such as water, sediment, and fish were collected from Geumpang River, Pidie Regency, Aceh Province. The study conducted several sample tests at the Banda Aceh Unsyiah Laboratory. The sample test results show that heavy metal Fe was the highest for all water samples analysed with a total of 0.244 mg/L. In addition, the most top-heavy metals for sediments were also recorded in Fe heavy metals for the whole areas tested. However, there is almost no Pb metal found in the whole areas. The results show that the highest heavy metal was found fish at 14,018 mg/g, i.e. Channa striata species. In addition, rivers experiencing pollution hugely affect living things and biota in water. It is suggested that the government policies and future supervision are needed so that environmental pollution, especially in rivers, can be reduced.
