Evaluation of Trace Metal Content by ICP-MS Using Closed Vessel Microwave Digestion in Fresh Water Fish

摘要

The objective of the present study was to investigate trace metal levels of different varieties of fresh water fish using Inductively Coupled Plasma Mass Spectrophotometer after microwave digestion (MD-ICPMS). Fish samples were collected from the outlets of twin cities of Hyderabad and Secunderabad. The trace metal content in different varieties of analyzed fish were ranged from 0.24 to 1.68 mg/kg for Chromium inCyprinus carpioandMasto symbollon, 0.20 to 7.52 mg/kg for Manganese inLabeo rohitaandMasto symbollon, 0.006 to 0.07 mg/kg for Cobalt inRastrelliger kanagurtaandPampus argenteus, 0.31 to 2.24 mg/kg for Copper inLabeo rohitaandPenaeus monodon, 3.25 to 14.56 mg/kg for Zinc inCyprinus carpioandMacrobrachium rosenbergii, and 0.01 to 2.05 mg/kg for Selenium inRastrelliger kanagurtaandPampus argenteus, respectively. Proximate composition data for the different fishes were also tabulated. Since the available data for different trace elements for fish is scanty, here an effort is made to present a precise data for the same as estimated on ICP-MS. Results were in accordance with recommended daily intake allowance by WHO/FAO.
