Abstract

The aim of this paper is to determine and discuss the Concentrations of Copper (Cu) in the different soft tissues of Perna viridis and surface sediments collected from western and eastern parts of Johore Singapore Causeway. In general, it is found that the different tissues of eastern mussel populations were found to have significant (p < 0.05) higher Cu levels than those in the western mussel populations. This indicated higher Cu bioavailability in the eastern part of causeway than that in the western part. The geochemical fractions (except for oxidizable-organic fraction) showed significant (p < 0.05) higher Cu levels in the eastern sediments than those in the western part of the causeway. This indicated higher Cu contamination in the eastern part of causeway than that in the western part. With consistent scientific reports of high metal levels in the eastern part of causeway between 2015-2018, it is predicted that there is a plausible constant source of anthropogenic metal contamination at the eastern part of the causeway beyond 2020 should there is no drastic effective control of the anthropogenic activities.

Highlights

The Straits of Johore (SOJ) is focused upon in this paper due to the significance from ecotoxicological point of view [1,2,3] such as monitoring of hydrochemistry changes in SOJ [4]

Summary

Introduction

The Straits of Johore (SOJ) is focused upon in this paper due to the significance from ecotoxicological point of view [1,2,3] such as monitoring of hydrochemistry changes in SOJ [4].

J Biomed Res Environ Sci. 2020 Aug 31; 1(4): 114-121. The eutrophicated condition of the SOJ could be the reason for the occurrence of high biomass diatom blooms and formation of the hypoxicanoxic zone in the SOJ [5]
