Abstract

Content of Copper, Zinc and Iron in the Bolaang River Sediments in Bakan Bolaang Mongondow Village

Micronutrients are essential nutrients needed by organisms in low amounts/ concentrations. The purpose of this study was to determine the content of copper (Cu), zinc (Zn) and iron (Fe) and the level of pollution in the sediments of the Bolaang River based on quality standards according to the Wisconsin Department of Natural Resources. The study was conducted in the village of Bakan, Lolayan District, Bolaang Mongondow Regency, sampling at five points on the Bolaang River was taken directly (grab sampling) and analyzed at the Environmental Biotechnology Laboratory (EBL) Bogor. There was only one sediment sample downstream river which its Cu content is under the pollution level (<32 mg Cu/kg). Two sediment samples posed toxic level below the permissible limit of 120 mg Zn/kg, i.e. The one sample at downstream and the other sample that occurring after sedimentation by meander. The result also detected that at all sampling points of Bolaang River, the Fe content of sediments in the Bolaang River are above the permissible standard pollution (40,000 mg Fe/kg) of the Wisconsin Department of Natural Resources.
