Accumulation of Heavy Metals in Fish after Chronic Exposure to the Industrial Effluent
Journal Title: Universal Journal of Environmental Research and Technology - Year 2013, Vol 3, Issue 6
Abstract
The present study aims to assess the accumulation of heavy metals in various organs of Mystus gulio (Ham.) after chronic exposure for 30 days at 1/10 th of LC50 to industrial effluent, collected from Lote M.I.D.C., Tal. Khed, Dist. Ratanagiri, Maharashtra. The concentrations of Cu, Fe, Zn, Cd, Ni, Co and Mn were measured. The result showed that the concentration of heavy metals from different organs were ranged from Cu 0.011 to 0.22 ppm, Fe 0.055 to 1.12 ppm, Zn 0.006 to 1.47 ppm, Co 0.001 to 0.002 ppm, and that of Cd, Ni, and Mn were below detectable level. The order of concentration of metals in the organs as: Zinc - Gills > Liver > Kidney; Copper – Kidney > Liver > Gills; Cadmium - Liver > Gills > Kidney. The concentrations of heavy metals in various organs were within the acceptable limits of international standards.
