The pond water is used by a variety of animals i.e. mammals, birds, duck, and fish. Sediments play a significant role in determining the overall environmental quality for the living organism. Therefore, in this work, chemical characterization of pond water and sediment in the largest coal burning basin of India i.e. Korba basin is described. Elements i.e. C, O, S, F, Cl, Na, Mg, Al, Si, P, K, Ca, Ti, Fe, As, Cr, Cu, Zn, Cd, Pb, and Hg were quantified. Toxic metals i.e. As, Cd, Hg, and Pb were highly enriched in the sediments, ranging from 36 -154, 0.14 -1.19, 0.12 -0.82 and 26 -127 mg/kg with mean value (p = 0.05) of 95 ± 12, 0.62 ± 0.11, 0.35 ± 0.08 and 75 ± 13 mg/kg, respectively. The concentration variations, pollution indices and sources of elements in water and sediment are discussed.

“…Table 1 shows the comparisons on the As concentrations in the sediment between Yangzonghai Lake and other lakes. Arsenic concentrations in the lake sediments of Yangzonghai are significantly higher than that of other Yungui plateau lakes, where As mainly originated from natural sources [26,27]. It is indicated that either groundwater or human pollution elevated the As contents in Yangzonghai Lake sediments.…”

Arsenic has attracted great interests from scientists and governments due to its high toxicity and ubiquitous occurrence in the environment. People who are chronically exposed to As through oral, dermal, or respiration may develop serious diseases (e.g., Black foot disease) and the risks of cancers may increase [1-3]. Arsenic is globally presented in the Earth's crust, including soils, sediments, water bodies, and rocks [4-6]. Arsenic occurs in more than 200 types of minerals, which mostly are ore minerals or the alteration products of ore minerals [7]. Some sulfide minerals such as pyrite, marcasite, and sphalerite may even contain As with concentrations of higher than 10,000 mg•kg-1 [7]. Arsenic occurrence in soils, sediments, and rocks may be largely caused by these As-rich minerals [8, 9]. On the

“…Several covers of JES have featured research on arsenic (Zan et al, 2014;Hao et al, 2015) and mercury , because of their environmental significance. Arsenic consistently ranks on top of the priority list of toxic substances, according to the Agency for Toxic Substances and Diseases Registry (ATSDR).…”

“…More than 100 million people around the world are at risk of exposure to arsenic at levels exceeding the World Health Organization guidelines (Nordstrom, 2002;WHO, 2011). Appropriately, JES has featured new analytical methods for the detection of arsenic (Hao et al, 2015), studies on its environmental fate and behaviour (Zan et al, 2014;Zhang et al, 2014), minimizing potential human exposure (Newbigging et al, 2015), and removal technologies (Du et al, 2014).…”
