Analysis of Trace Metal Bioaccumulation in Fish and Man; Health Risk Impact

Trace metals occur during natural processes and are also obtained anthropogenic activities. Streams, lakes rivers surrounded by farmlands engaged in the use of metal-enriched fertilizers have shown a possible positive correlation to rise chemical, organic water-soluble for long period. there is tendency high correlations trace source waters. Furthermore, increasing level fish alarming has spurred scientists make research on dangers caused resulting metal accumulation bioaccumulation life cells. This study aims at assessing sources aquatic environment, impact their human health risk impact, negative effects been attributed such as irritation gastrointestinal mucosa, nephritis, necrosis, neurological behavioural disorders death amongst others). The ingestion, absorption uptake usually toxic result harmful damage life. Since most taken up non-biodegradable, can bioaccumulate bio-magnify. Over time, accumulated affect growth development stages from production viable eggs, hatchability laval, fingerlings juvenile stages. so because early more sensitive than maturing adulthood. In conclusion, results presence effect bio-magnification reviewed this paper. recommends that proper assessment treatment all forms wastewater, agricultural waste, sewage, industrial effluents be carried out before discharge into environment.
