Abstract
Major sources of toxic metals arising from human activities are domestic and industrial wastewaters and their associated solid wastes. Metals like, arsenic, chromium, mercury, nickel and lead exhibit toxicity at certain levels. Marine fishes exposed to heavy metals have been consumed as sea foods and, hence are a connecting pathway for the transfer of toxic heavy metals into human beings. The temporal distribution of heavy metals in three fish species of Visakhapatnam, east coast of India, determined using flame atomic absorption spectrophotometer. The concentration of heavy metals viz., Cr, Mn, Co, Cd and Pb varied seasonally. The overall mean concentration of metal magnification in pre-monsoon season is Mn>Co>Cr>Pb>Cd, whereas in monsoon season is Mn>Co>Cr>Cd>Pb, while in post-monsoon season, the order of magnification is Mn>Co>Cd>Pb>Cr respectively. This paper makes an attempt to identify the toxicity levels in the three fishes viz., Pampus argenteus, Rastrelliger kanagurta and Upeneus vittatus in the Visakhapatnam coast which is one of the most vulnerable systems for pollution of different types.
