Bioaccumulation of Heavy Metals in Clarias Gariepinus Exposed to Untreated Paint Effluent
Journal Title: International Journal of Trend in Scientific Research and Development - Year 2020, Vol 4, Issue 2
Abstract
This study presents the heavy metal accumulation profile in Clarias gariepinus catfish exposed to untreated paint effluent. Sub lethal concentrations of paint effluent were used to pollute catfish aquaria. This was followed by isolation and identification of microorganisms from the polluted aquaria after 96 h using conventional microbiological techniques. The tissue heavy metal composition and physicochemical parameters of the aquaria were also monitored using standard analytical methods. Microbial load in the range of 10.00a±2.00 to 189.00d±20.52 cfu ml on tissues of catfish were observed. The heavy metals present in the paint effluent were mainly Lead 1.20±0.01ppm and Zinc 0.34±0.01ppm . No significant difference in the proximate analysis between the tissue of catfish from the control and the polluted aquaria were observed. Catfish tissue accumulated Lead 0.16 ppm from the polluted aquaria. Persistent exposure through pollution by effluent in aquatic environment can lead to increased metallic Lead bioaccumulation that could be unhealthy for both the fish and human consumption. Therefore, indiscriminate discharge of untreated effluent from industrial sites into water bodies should be discouraged. Orimoloye, M.
