What is Concentration of Trace Metals and Biochemical Alterations in Various Species of Fishes along the West Coast of India about?

This study seeks to evaluate levels of seven trace metals (Cr, Mn, Fe, Cu, Zn, Pb and Hg) and biochemical (proteins, lipids and carbohydrates) alterations in muscle tissue of 27 commercially important fish species collected from 6 different estuaries along the west coast of India. Estuaries along the central west coast of India (Maharashtra coast) receive wastewater from agricultural, domestic and industrial sources. The study was performed using ICP-OES, GF-AAS, FIMS and an UV-Visible spectrophotometer. The obtained results revealed that the abundance of trace metals and biochemical compounds in fish tissue followed the order: Fe (370.0 ± 6.0 μg/g) > Zn (92.0 ± 4.2 μg/g) > Mn (23.0 ± 1.24 μg/g) > Cu (27.9 ± 1.8 μg/g) > Cr (1.2 ± 0.18 μg/g) > Pb (0.28 ± 0.06 μg/g) > Hg (0.09 ± 0.01 μg/g) and proteins (43.5 ± 1.6 mg/g) > lipids (23.6 ± 1.6 mg/g) > carbohydrates (3.9 ± 1.8 mg/g). The results indicate that various levels of trace metals exist in the studied fish species, but the concentrations are within permissible limits set by the USFDA, FAO/WHO, and EU for human consumption, except Mn (< 1.0 μg/g) and Fe (< 100.0 μg/g) in some of the species. Cu (r = -0.39) and Zn (r = -0.85) show
