“…On average, the grain sizes <63 m% of studied sediments from the ex-mine catchments are determined to be only 28.9%. Numerous studies reported that great quantities of metals are associated with very fine-grained particles of sediments such as clay <2 m and <63 m [12,35]. This condition is due to these particles having larger surface area to volume ratio than coarse particles.…”

“…Hydroxylamine chloride (pH 2) (0.25 M) is usually used in AR fraction as a reagent to release metals from manganese, iron oxides, and hydroxide and possibly with carbonates too [15]. The AR fraction is used to extract metals contained in iron and manganese oxides and hydroxides which can be released under reducing conditions [11,12]. In AR fraction, the metal concentrations were in the order of Fe, Al, Pb, and Cd.…”

“…Therefore, the assessment of sediment contamination requires full knowledge of the mineral phase with which metals are associated, its physicochemical forms, and strength of binding involved [6,11]. The sequential extraction technique has been developed to provide quality information pertaining to the physicochemical forms, processes that influence the mobilization, bioavailability, and distribution of trace metals in sediments [11,12]. Thus, in the present study, the modified sequential extraction technique is carefully utilized to assess the distribution and levels of heavy metal in sediments.…”

An assessment of the abandoned mine impacts on the concentrations and distribution of heavy metals in surface sediments and plant species within the vicinity of an ex-iron mine in Malaysia was conducted. The sequential extraction method was used to extract anthropogenic metals in sediments. The results showed that metals in EFLE, AR, and OO fractions were higher than ambient concentrations which indicate that heavy metals have been loaded from ex-iron mining area into the surrounding aquatic environments. The metal accumulation in the four dominant plant species grown naturally within the vicinity of Bukit Besi exiron mining was investigated. Exceptional elevated concentrations of metal were found in plants and surface sediments. Several established criteria were applied to determine the hyperaccumulator plants. The results revealed that Melastoma malabathricum and Pityrogramma calomelanos are classified as Fe and Al hyperaccumulators, while Scirpus triqueter, Melastoma malabathricum, and Pityrogramma calomelanos were undoubtedly hyperaccumulator for Cd.

“…Organic matter form complexes with heavy metals limiting their bioavailability for plant and animal uptake (Hong et al 2012). In their study, Idriss and Ahmad (2012) observed that the organic fraction had the second highest content of metal after the residual fraction. They explained the correlations between (1) organic matter and metals and (2) pH and metals, with respect to metal solubility, ultimately their availability.…”

Water bodies are the final sinks of all pollution with more than 90% of contaminants found in suspended particulates and bottom sediments. Only less than 10% is retained in the water column yet it attracts and receives great research attention. The pollution status and the potential ecological risk of three pools of water along a stream due to heavy metal enrichment from a nearby active gold mining tailings dam were assessed. The upstreamdownstream and sedimentological approaches to ecosystem health assessment were used. Potential uses of pool water were also evaluated based on measured water quality parameters. Heavy metals in water and sediment were determined using Flame Atomic Absorption Spectrometry. Results revealed that salinisation, acidification and heavy metals were exported from a mining tailings dam to the stream. The degree of contamination of pool water by heavy metals dictated water uses. Heavy metal concentrations imposed water use restrictions for aquatic life in a pool which directly received discharge from the mine tailings dam. The average heavy metal concentrations in sediments were lower than the standard shale values. Sediment quality guidelines and pollution indices showed that the stream was not polluted with heavy metals, thus posed no potential ecological risk. Continuous monitoring of tailings discharge and wash off is important to safeguard aquatic ecosystem and public health.
