Concentrations of Cu, Mn, Zn, Fe, Cr, and Pb were estimated using ICP-MS in nine commercially important and locally consumed fish species (Sarda orientalis, Scomberomorus commerson, Rastrelliger kanagurta, Sardinella longiceps, Paraplagusia bilineata, Cynoglossus lida, Cynoglossus macrostomus, Lepturacanthus savala, and Siganus javus) collected from coastal waters of Kalpakkam, eastern part of India. Their concentration (μg g−1) in the examined fish species ranged as follows: Cu (0.8–6.5), Zn (14.3–27.9), Mn (0.5–8.8), Fe (17.6–117.0), Cr (0.24–1.78), and Pb (0.18–2.29). Concentrations of most of the metals in the fish species studied were found to be safe for human consumption barring Mn.
