Abstract

On 15th June 2015 W.D.N Wickramarachchi was ADDED as an author on this paper - The Editor. Currently, an aquatic ecosystem of Sri Lanka is faced with acute environmental problems due to trace metal pollution. Bomburuella is one of reservoirs situated in Nuwara-Eliya District, Sri Lanka. Trace metal pollution of this reservoir has taking placed due to various anthropogenic activities. Therefore, it is very important to determine the cause for bioaccumulation of trace metals in fish tissues. The aim of this study was to determine the levels of selected trace metals in the tissues of fish species (Cyprinus carpio/Common Carp). Samples were analyzed using Atomic Absorption Spectroscopy (AAS) to determine selected trace metals namely mercury (Hg), lead (Pb) and cadmium (Cd). Results revealed that, the mean concentration of trace metal namely Hg, Pb and Cd recorded as 0.56 ± 0.15 mg/kg,0.50 mg/kg).

Highlights

Pollution of the aquatic environment by inorganic chemicals has been considered a major threat to the aquatic organisms including fishes (Akan et al, 2012).Contaminations of trace metals in inland water bodies can be determined using the metal levels in water; sediments and resident biota especially using fish species (Senarathne and Pathirathne, 2007)
Trace metal pollution in aquatic ecosystems is one of the growing problems worldwide and it has been increasing at an alarming rate (Ogoyi et al, 2011)
Standard length, and total weight of fish samples are shown in Table 2, whereas Table 3 indicates the concentration of trace metals in fish tissues

Summary

Introduction

Pollution of the aquatic environment by inorganic chemicals has been considered a major threat to the aquatic organisms including fishes (Akan et al, 2012).Contaminations of trace metals in inland water bodies can be determined using the metal levels in water; sediments and resident biota especially using fish species (Senarathne and Pathirathne, 2007). Trace metals are released into aquatic environment through naturally processes and anthropogenic activities. Anthropogenic activities have led to increased contamination of the environment due to the use of toxic metals in industrial processes. Trace metals such as Hg and Cd can be categorized as nonessential metals that are toxic to animals and human even at very low concentrations (Wright and Welbourn, 2002). Trace metal such as Pb is included in between essentials and non-essentials metals (Valavanidis and Vlachogianni, 2012)
