Abstract

Heavy metals such as mercury (Hg), lead (Pb), cadmium (Cd), arsenic (As), chromium (Cr), copper (cu), nickel (Ni) and selenium (se) were analyzed in water sample of Ennore coastal area and different parts of the marine food fish, Mugil cephalus. The samples were collected from oil spilled area near at Ennore, after the ship accident occurred on the month of January 2017. The highest heavy metal concentrations in different parts of the fish were noticed as follows: mercury (0.87 ppm) in liver, lead (2.45 ppm) in fried tissue, cadmium (0.56 ppm) in liver, arsenic (1.22 ppm) in intestine, chromium (1.35ppm) in liver, copper (0.34ppm) in tissue, and selenium (6.32 ppm) in tissue. The water quality parameter in the Ennore coastal area were analyzed and presented in this paper. The present study was compared with the earlier finding of the Ennore coastal area. Based on the results there was much contamination in the water and fish sample and hence the fish is not fit for human consumption.
