Abstract
Heavy metals are an important group of chemical contaminants and food is the major vehicle for entry into the system. Fish constitute
a major source of heavy metals in food. Concentration of heavy metals in commercially important species of fish, shellfish and fish
products from fish markets in and around the Cochin area was evaluated using an atomic absorption spectrometer. The concentration
ranges of Cd, Pb, Hg, Cr, As, Zn, Cu, Co, Mn, Ni, and Se in the samples were <0.07–1, <0.07–1.32, <0.05–2.31, <0.05 to 3.65, <0.1–4.14,
0.6 to 165, 0.15 to 24, <0.02 to 0.85, <0.08 to 9.2, <0.032–1.38 and; <0.03–1.35 mg/kg, respectively. The present study showed that different
metals were present in the samples at different levels but within the maximum residual levels prescribed by the EU and USFDA
and the fish and shellfish from these areas, in general, are safe for human consumption.
