Abstract:
The current study was carried out to determine the levels of heavy metals like copper (Cu), zinc (Zn), iron (Fe), lead (Pb) and cadmium (Cd) in the muscle and liver parts of shrimp (Plesionika martia) species. Atomic absorption spectrometry (AAS) was used to assess and evaluate the levels of these metals from the two parts in seasonal wise accumulation. The results of this study shown that the total mean values of metal accumulation in muscle part was, copper (5.43 ppm), zinc (12.99 ppm), iron (2.92 ppm), lead (0.21 ppm) and cadmium (0.66 ppm) whereas in liver part, copper (123.82 ppm), zinc (31.20 ppm), iron (21.22 ppm), lead (1.97 ppm) and cadmium (1.03 ppm). The overall mean metal concentration of muscle was Zn>Cu>Fe>Cd>Pb, whereas the magnification of mean metal concentration in liver part were accumulated as Cu>Zn>Fe>Pb>Cd respectively. This study highlights those toxic metals are found to be below the recommended tolerable levels in shrimp of WHO (World Health Organization) and seafood safety standards which may not constitute a health hazards for consumers.
