Marble industry effluents cause an increased bioaccumulation of heavy metals in Mahaseer ( Tor putitora) in Barandu River, district Buner, Pakistan

摘要

AbstractThe present study was conducted to evaluate the impact of marble industry effluents on the accumulation of heavy metals in selected tissues of mahaseer (Tor putitora) in Barandu River. Fish samples were collected from three selected sites (upstream (US), effluents/industrial (IS), and downstream (DS) sites) on monthly basis for 8?months. Heavy metal concentrations were determined in fish tissues using Atomic Absorption Spectrophotometer. Liver accumulated the highest level of metal concentrations while the lowest concentrations were found in muscles inT. putitora. Among metals, Fe was reported in the highest amount whereas the lowest was Cd in all the fish organs. In all the months, the metal concentrations were significantly higher (P?P?P?]]>
