“…The priority heavy metals in this study are Cu, As, Pb, Cd, Zn, and Mn, which are among the major heavy metal pollutants as specified by the Malaysian DOE and WHO, and six general water quality parameters, namely pH, conductivity, DO, COD, BOD, and TSS. These selected pollutants are of concern and frequently studied in the pollution assessment of Malaysian lakes [26,48,49], and rivers for water quality assessments and index classification for different uses [31,50,51]. The mining operation is associated with toxic metal pollutants and water quality impairment due to high suspended solids (SS), electrical conductivity (EC), and COD [52][53][54][55].…”

A B S T R A C TThreat posed by the heavy metals has been increasing globally rendering many water bodies unfit for human consumption. This could be due to the increase in concentrations of these metals above natural background. This article reviews the literature data on variation of water quality in rivers, lakes, and ex-mining ponds in Malaysia and other selected countries. World Health Organization (WHO), United States Environmental Protection Agency, and Malaysian water quality standards (INWQS) are used as the baseline for the pollution and health risk assessments. It illustrates that concentrations of Pb, Cd, and As in lakes and ex-mining ponds, and Mn, Cd and Pb in rivers exceed permissible limits for direct consumption. The levels of dissolved oxygen, TSS, and chemical oxygen demand (COD) are not within WHO and INWQS limits, pH of lakes and ex-mining ponds are lower than reference standards while that of rivers are high. Principal component analysis reveals that TSS, COD, BOD, Pb, and As are highly associated with ex-mining ponds. Cluster analysis shows similarity in pollution source between lake and ex-mining ponds. Risk assessment revealed that high chronic daily intake and metal index were beyond acceptable limit indicating high risk and exposure to toxic metals.

“…Since heavy metals are chronically circulating between water and particles, heavy metal pollution is more severe than organic matter or microorganism pollution [4]. The existing relevant research is focused on heavy metals in surface water and shallow groundwater [5], but is rarely targeted at the sediments of subsidence lakes. According to the priority pollutant lists (heavy metals) in and outside China as well as the situations in Huaibei mining areas, we selected five heavy metals (Sb, As, Pb, Zn, and Cd) that might be environmentally risky.…”

Surficial sediments and water (27 samples each) were collected from three representative lakes collapsed by mining activities in Huaibei, China. Contents of heavy metals (Sb, As, Cd, Pb, Zn) in both water and sediments were detected via atomic absorption spectrophotometry and atomic fluorescence spectrometry, respectively. The variation coefficient (C.V.) of each heavy metal as well as the partition coefficient (Kd) between surficial sediments and water was calculated. The ecological risks of heavy metals in collapsed lakes were assessed via geoaccumulation index (I geo ), and we estimated the Pearson correlation coefficients between heavy metals. Together with the real situations around collapsed lakes, we resolved the sources of heavy metals. We found that the contents of heavy metals in water were basically below Surface Water Quality Standard I. The contents of heavy metals in the majority of sediment samples exceeded the background levels in the Yangtze River and Huai River areas, but were below the threshold effect concentration. The spatial distributions of heavy metals in surficial sediments were not uniform, as the C.V.s indicate medium variations. Analysis of Partition coefficient showed that Lieshan collapsed lake (LSH) was under severe risk. An analysis of I geo revealed gentle-medium ecological risks from Sb, As, and Cd. The classification and frequency distributions of I geo of five heavy metals indicate that the ecological risk of Cd was the largest. The ecological risk was lowest in Yangzhuang collapsed lake (YZH). These results were confirmed by analysis of C.V. and Kd. Analysis of heavy metal sources showed that the inputs of Sb and As into the three collapsed lakes were human-driven and very complex, probably due to point-source pollution, including leaching from gangue piles and industrial discharge. Cd mainly originated from non-point-source agricultural pollution, while Pb and Zn might mainly originate from natural sources.

“…All three clusters were significantly differentfrom each other based on water quality variables factor (Table 4). From analysis, the result shows that the difference between clusters is highly significant (Two-way ANOVA: F [2,8] = 38.11, p< 0.05)and also the interaction between clusters and water quality variables [Two-way ANOVA: F [2,8] = 24.77, p< 0.05). In PCA, only prominent factors are counted for analysis to find the significant difference between the samples.…”

“…Construction and exploration of deep wells at Carey Island andKelanang village in the district were also conducted to seek groundwater resources [2].Recently, a further study has been carried out to determine the occurrence of freshwater lens and seawater intrusion in the island [3][4][5]. Other studies on contamination of aquifers and water sources have also been conducted [6][7][8][9].…”
