Distribution sources and modified degree of contamination of trace elements in Linggi estuary surface sediments Malaysia. pp. 109-119. ISSN 2672-7226

The purpose of this study is to assess the trace elements of barium (Ba) bromine (Br) cesium (Cs) cobalt (Co) hafnium (Hf) iron (Fe) manganese (Mn) rubidium (Rb) scandium (Sc) and vanadium (V) in the surface sediments of Linggi estuary in Negeri Sembilan Malaysia using the neutron activation analysis (NAA) technique. Results showed that the average concentration of Br Cs Hf Rb Sc and V were 75.1 12.6 10 146 10.6 and 80.5 mg/kg respectively which were all higher than the upper continental crust (UCC) reference values. However the average concentration values of Ba Co Mn and Fe were 272 6.39 350 and 26 547 mg/kg respectively which were all relatively lower compared to the UCC values of the respective elements. The provenance of Br and Hf were from seawater and marine organisms while Cs and V came from from anthropogenic activities such as discharge from electronic factories and vehicle workshops. The element of Rb and Sc originated from geogenic processes such as erosion landslide and weathering. Overall the trace element contamination in surface sediments of Linggi estuary was categorised as moderate to highly modified degree of contamination (mCd ) and these could result in adverse effects on benthic dwelling organisms and aquatic life.

Abstract

The purpose of this study is to assess the trace elements of barium (Ba) bromine (Br) cesium (Cs) cobalt (Co) hafnium (Hf) iron (Fe) manganese (Mn) rubidium (Rb) scandium (Sc) and vanadium (V) in the surface sediments of Linggi estuary in Negeri Sembilan Malaysia using the neutron activation analysis (NAA) technique. Results showed that the average concentration of Br Cs Hf Rb Sc and V were 75.1 12.6 10 146 10.6 and 80.5 mg/kg respectively which were all higher than the upper continental crust (UCC) reference values. However the average concentration values of Ba Co Mn and Fe were 272 6.39 350 and 26 547 mg/kg respectively which were all relatively lower compared to the UCC values of the respective elements. The provenance of Br and Hf were from seawater and marine organisms while Cs and V came from from anthropogenic activities such as discharge from electronic factories and vehicle workshops. The element of Rb and Sc originated from geogenic processes such as erosion landslide and weathering. Overall the trace element contamination in surface sediments of Linggi estuary was categorised as moderate to highly modified degree of contamination (mCd ) and these could result in adverse effects on benthic dwelling organisms and aquatic life.
