摘要
Concentrations of toxic metals viz. mercury (Hg), cadmium (Cd) and lead (Pb) were evaluated in four species of fishes (Sardinella longiceps, Selaroides leptolepis, Epinephelus quoyanus and Lethrinus lentjan), one species of shrimp (Penaeus semisulcatus) and one species of crab (Portunus sanguinolentus) sampled from Thoothukudi, Keelakarai and Veerapandian pattinam of Gulf of Mannar, Southeast coast of India. Results revealed accumulation of these metals in the following order Hg > Cd > Pb. Hg concentration was found to be higher in Po. sanguinolentus followed by E. quoyanus, Pe. semisulcatus and L. lentjan however, the same was absent in Sa. longiceps and Se. leptolepis. Cd concentration was recorded in decreasing order in Po. sanguinolentus > Pe. semisulcatus > L. lentjen > E. quoyanus > Sa. longiceps > Se. leptolepis. Pb was detectable only in four species. Results of One-way ANOVA revealed significant variations (p < 0.05) in accumulation of Cd in Sa. longiceps, Se. leptolepis and Pe. semisulcatus and Hg in E. quoyanus, L. lentjan and Po. sanguinolentus. Variations noted in Pb were not statistically significant throughout. © 2016, Zoological Society, Kolkata, India.
