Abstract

Trace metals concentration and proximate composition of raw and boiled silver pomfret (Pampus argenteus) from coastal area and retail market were determined to gain the knowledge of the risk and benefits associated with indiscriminate consumption of marine fishes. The effects of cooking (boiling) on trace metal and proximate composition of silver pomfret fish were also investigated. Trace element results were determined by the Energy Dispersive X-ray Fluorescence (EDXRF) Spectrometer wherein fish samples from both areas exceeded the standard limits set by FAO/WHO for manganese, lead, cadmiumm and chromium and boiling has no significant effects on these three metal concentrations. Long-term intake of these contaminated fish samples can pose a health risk to humans who consume them.

Highlights

Fish is a healthy food for most of the world’s population developing countries in contrast to meat, poultry, and eggs
The purpose of the present study was to determine the concentrations of trace metals by using Energy Dispersive X-ray Fluorescence (EDXRF) Spectrometer along with proximate composition of silver pomfret fish from costal area of Cox’s Bazar and retail market of Dhaka city where silver pomfret fish were supplied from coastal area of Bay of Bengal
The international official regulatory agencies like WHO and FAO have set limits for trace metal contaminations above which the fish and fishery products are unsuitable for human consumption

Summary

Introduction

Fish is a healthy food for most of the world’s population developing countries in contrast to meat, poultry, and eggs. Trace metals are present in water from natural sources such as the rocks of the sea bed and accumulated as a result of human activities such as emissions from industrial processes These elements are taken up by marine fishes which are higher up the food chain. The concentrations of many elements including mercury, arsenic, lead, and cadmium in fish can be relatively high compared to other foods. Many of these metals such as iron, copper, cobalt, manganese, molybdenum, nickel, and zinc are essential trace elements and play important roles in biological systems. Elevated concentration of manganese and nickel has been found to be toxic to aquatic organism [5, 6]
