A review on the accumulation of heavy metals in coastal sediment of Peninsular Malaysia

Abstract

Purpose This study aims to examine the metal pollution in coastal sediment in the Peninsular Malaysia. Design/methodology/approach Approximately 141 published studies were screened from 1,285 documents and reviewed to determine the existing pollution status in the coastal areas of Peninsular Malaysia and the metals under review were Pb, Hg, Cd, Ar, Cu, Zn, Cr and Ni. Sources of pollutants and their effect on biological systems, marine organisms and human health were addressed in this review as well as recommendation of heavy metal removal or remedies in short. Emphasis is placed on marine pollution, particularly on the toxic metal accumulation in biota. Findings This study has revealed the different concentrations of pollutants, low, moderately, and chronically contaminated areas from heavy metals and the consequences to aquatic ecosystem and indirectly to human health, since an increasing in the coastal developments in Peninsular Malaysia. Originality/value This study has revealed the different concentrations of pollutants, low, moderately, and chronically contaminated areas from heavy metals and the consequences to aquatic ecosystem and indirectly to human health, since an increasing in the coastal developments in Peninsular Malaysia.

Performance of Avicennia Alba and Rhizophora Mucronata as Lead Bioaccumulator in Bjbr Coast, Indonesia

“…The awareness of the Pb accumulation is therefore vitally necessary for the use of fish for human consumption. Although the Pb bioavailability in the marine environment is poor, its constant bioaccumulation by aquatic organisms, especially fish, poses serious threats to the human health if these organisms are consumed [Yunus et al, 2020]. The Pb concentrations in A. alba and R. mucronata found in this study are lower than some previous related studies.…”

Various Natural and Anthropogenic Factors Responsible for Water Quality Degradation: A Review

“…These circumstances include the contrast between artificial and geochemical substances, as well as the type and nature of untreated wastewater, suspended particles, and chelating agent quantities [153]. In suspended solids, colloidal particulate matter, and naturally/synthetic compounds, the aquatic environment is described in longitudinal variations and vertical variations in the living form concentrations densities, blending level, and redox condition [154].…”

Spatial and Temporal Water Quality Evaluation of Heavy Metals of Habbaniyah Lake, Iraq

“…Due to their toxicity and alleged persistence within aquatic settings, interest in heavy metals (HMs) in environmental conditions has increased in past years [2,3]. Heavy metals, which include both vital and nonessential elements, are particularly important in ecotoxicology because they are very persistent and can all be harmful to live species [4][5][6]. Trace metals are among the most important environmental toxins and the presence of natural or biota in water sources of anthropogenic [7].…”

“…To evaluate the state of pollution in the environment, heavy metal concentrations can also be analyzed and distributed in the environment. [5,10,11]. Heavy metals are most much the source of pollution of the water system because of numerous anthropological causes such as industrial wastewater, drainage of municipal surface water, agriculture processes, etc.…”
