Determination of heavy metal contamination and health risk assessment between ex-mining pond and river fish / Nooraini Jamal
Anthropogenic activities continuously increase the amount of heavy metals in the environment, especially in aquatic ecosystem. Increase in population, urbanization, industrialization and agriculture practices have further aggravated the pollution of heavy metals in aquatic ecosystem. As heavy metals...
