ABSTRACT

The objective of the present study was to investigate the heavy metal content in fresh water fish collected from the outlets of twin cities of Hyderabad and Secunderabad, Andhra Pradesh, India. The heavy metal content of fresh water fish varieties was investigated using Inductively Coupled Plasma Mass Spectrophotometer (MD-ICP-MS) after microwave digestion. Heavy metal content in fresh water fish were ranged from 52-680 µg/kg for Nickel in Rastrelliger kanagurta and Stromateus sinensis, 38-690 µg/kg for Arsenic in Rastrelliger kanagurta and Pompus argenteus, 3-62 µg/kg for Cadmium in Masto symbollon and Pompus argenteus and 27-108 µg/kg for Lead in Panaeus monodon and Rastrelliger kanagurta respectively. Results were in accordance with recommended human daily intake values except for arsenic, which were in agreement with WHO/FAO recommended values. Since the available data for heavy metal content in fish is scanty, efforts were made to present a precise data for the same as estimated on ICP-MS. This study may provide information on important heavy metal concentrations of fresh water fish and shell fish and therefore provides an essential baseline data with which future levels may be compared and evaluated. Results were in accordance with recommended daily intake allowance by WHO/FAO.
