The Distribution of Heavy Metals and Nutrients along Selangor River and its Adjacent Mining Ponds, Malaysia

2016 International Journal of Advances in Agricultural & Environmental Engineering  
Selangor River, one of major rivers in Malaysia, supplies about 70% of drinking water in Kuala Lumpur areas. There are also many ex-mining ponds along Selangor River, which have been used as an additional water source. Despite its importance, the water quality, especially the distribution and abundance of heavy metals, has been understudied in Selangor River and adjacent mining ponds. Water samples were collected from these areas, and the high concentrations of Aluminum (Al) and Iron (Fe) were

In addition, high ammonia concentrations were also observed in some mining ponds, suggesting that they could also be the excess nutrient sources. Additional study is needed to estimate the effects of the heavy metals on the surrounding environments as well as human health risks.
