Abstract

This study was conducted to analyze the accumulation of cadmium, mercury and arsenic in different organs of Sperata sarwari. The fish were collected from Indus River, Head Taunsa, Dera Gazi Khan, Punjab, Pakistan. The organs of collected fish were separated and frozen at -20 oC. The organ samples were digested by using perchloric acid and nitric acid. The concentration of accumulated metals in organs was measured by using an atomic absorption spectrophotometer. The kidney was found most targeted organ for the accumulation of above mentioned heavy metals. All other organs also accumulate a significant amount of heavy metals. This study concludes that heavy metals of cadmium, mercury, and arsenic are found in the natural water and accumulate in different organs of Sperata sarwari.

Highlights

  • This study concludes that heavy metals of cadmium, mercury, and arsenic are found in the natural water and accumulate in different organs of Sperata sarwari

  • Materials and methods Sampling Fish was collected from Head Taunsa, It is barrage situated on the Indus River, Taunsa, Dera Gazi Khan, Punjab, Pakistan

  • The distribution of cadmium depends upon exposure route, dose and time, exceptions occur in different fish species [26]

Summary

Introduction

In developing countries fish is a cheap source and eicosapentaenoic acid (EPA) [4]. If the of animal proteins and an important food fish is contaminated the health benefits of world widely [1]. The final volume of about 10 ml was used after adding distilled water was used for analysis. The accumulation (77.15±1.07) was less as compared to kidney and liver but in muscles, the accumulation (71.85±1.36) was lower as compared to the above-mentioned organs. The accumulation of Cd was found in this order Kidney > Liver > Muscles > Gills > Skin (Table 1, Fig. 1). The accumulation of arsenic was found in this order Kidney > Gills > Liver > Muscles > Skin (Table 1, Fig. 2). Accumulation was found in the following order Kidney > Liver > Muscles > Gills > Skin (Table 1, Fig. 3). Similar alphabets in columns are insignificant and vice versa (P < 0.05), ANOVA (Mean ±Standard Deviation), Tukey’s Test
