“…For example, Wang et al [20] studied the As concentrations in the lacustrine sediment, lake water, and aquatic organisms, and investigated the risk of As pollution in Yangzonghai Lake. Zhang et al [21][22][23] studied the As concentrations in lake water and lake sediments, and assessed the pollution level by calculating the geoaccumulation indexes. Qi et al [24] investigated the source and speciation of As in this lake, and suggested that As in the lake was mainly polluted by the chemical industry.…”

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
