A comparative study on the accumulation of toxic heavy metals in fish of the Oman Sea: effects of fish size, spatial distribution and trophic level

This study was conducted to evaluate heavy metal (HMT) accumulation in some commercially pelagic (Scomberoides commersonnianus, Rastrelliger kanagurta, Saurida tumbil) and demersal fish (Parastromateus niger, Alepes melanoptera, Nemipterus japonicus, Alepes melanoptera) of Oman Sea. Fish samples wer...

Description
Summary:This study was conducted to evaluate heavy metal (HMT) accumulation in some commercially pelagic (Scomberoides commersonnianus, Rastrelliger kanagurta, Saurida tumbil) and demersal fish (Parastromateus niger, Alepes melanoptera, Nemipterus japonicus, Alepes melanoptera) of Oman Sea. Fish samples were collected by trawl from inshore area of four stations along Chabahar bay. The heavy metal (Ni, Cr, Hg, Cd, Pb) concentrations in the muscle tissue of the fishes were assayed. In addition, the relationships between the level of heavy metal accumulation in fish tissue and fish size were studied. The demersal species accumulated more heavy metals compared to pelagic fishes (p
