A Review on the Effects of Heavy Metals on Aquatic Animals

The development of industries and the uncontrolled increase population, agricultural areas use fertilizers pesticides have caused industrial municipal wastewaters as well effluents with heavy metals to enter water ecosystems. After entering aquatic ecosystems, accumulate in tissues eventually food chain. Research on metal pollution ecosystems is important from a public health perspective, maintaining balance those preventing biodegradation due adverse effects pollutants. So, researchers focused determining level various sources, how are absorbed by animals, bioaccumulation possibility using animals biological indicators based pollutant monitoring. Due importance this issue, present study has investigated effect fish.
