“…Most of the heavy metal ions are deposited in the sediment because of adsorption, hydrolysis, and co-precipitation (Gaur et al, 2005). Ghosh et al (2004) found that water-soluble forms of As were much more toxic than its insoluble forms. Long-term contamination with heavy metal and As could slow down bacterial growth, alter the soil microbial community composition, and exert a greater inhibitory effect on the enzymes' activities (Ghosh et al, 2004;Lorenz et al, 2006;Zhou et al, 2009;Han et al, 2013;Marabottini et al, 2013).…”

Pollution discharge disturbs the natural functions of water systems. The environmental microbial community composition and diversity are sensitive key indicators to the impact of water pollutant on the microbial ecology system over time. It is meaningful to develop a way to identify the microbial diversity related to heavy metal effects in evaluating river pollution. Water and sediment samples were collected from eight sections along the Tiaozi River where wastewater and sewage were discharged from Siping City in northeastern China. The main pollutants contents and microbial communities were analyzed. As the primary metal pollutants, zinc (Zn) and arsenic (As) were recorded at the maximum concentrations of 420 and 5.72 μg/L in the water, and 1704 and 1.92 mg/kg in the sediment, respectively. These pollutants posed a threat to the microbial community diversity as only a few species of bacteria and eukaryotes with strong resistance were detected through denaturing gradient gel electrophoresis (DGGE). Acinetobacter johnsonii, Clostridium cellulovorans, and Trichococcus pasteurii were the dominant bacteria in the severely polluted areas. The massive reproduction of Limnodrilus hoffmeisteri almost depleted the dissolved oxygen (DO) and resulted in the decline of the aerobic bacteria. It was noted that the pollution reduced the microbial diversity but the L. hoffmeisteri mass increased as the dominant community, which led to the overconsuming of DO and anaerobic stinking water bodies. Water quality, concentrations of heavy metals, and the spatial distribution of microbial populations have obvious consistencies, which mean that the heavy metals in the river pose a serious stress on the microorganisms.

“…The water demand of rice is particularly high; the volume of water used for irrigation of Boro rice in the Indo-Gangetic Plain are in the range between 1000 and 1800 mm/a (Gupta et al, 2002;Huq et al, 2003). Though the potential risk is evident, studies on the impact of irrigation with high As groundwater on soil and crop has attracted some attention only during the last couple of years (Abedin et al, 2002;Sanyal and Nasar, 2002;Roychowdhury et al, 2002;Alam et al, 2003;Duxbury et al, 2003;Gosh et al, 2004;Ahmed et al, 2003 and papers therein). These works document the enrichment of As in soil and a limited uptake by different plants, including rice and wheat, but relatively little is known about the mechanisms of enrichment and mineral speciation of As in soil (Inskeep et al, 2003;Takahashi et al, 2004).…”

The continuous increase in the production of metals and their subsequent release into the environment has lead to increased concentration of these elements in agricultural soils. Because microbes are involved in almost every chemical transformations taking place in the soil, considerable attention has been given to assessing their responses to metal contaminants. Short-term and long-term exposures to toxic metals have been shown to reduce microbial diversity, biomass and activities in the soil. Several studies show that microbial parameters like basal respiration, metabolic quotient, and enzymatic activities, including those of oxidoreductases and those involved in the cycle of C, N, P and other elements, exhibit sensitivity to soil metal concentrations. These have been therefore, regarded as good indices for assessing the impact of metal contaminants to the soil. Metal contamination has also been extensively shown to decrease species diversity and cause shifts in microbial community structure. Biochemical and molecular techniques that are currently being employed to detect these changes are continuously challenged by several limiting factors, although showing some degree of sensitivity and efficiency. Variations and inconsistencies in the responses of bioindicators to metal stress in the soil can also be explained by differences in bioavailability of the metal to the microorganisms. This, in turn, is influenced by soil characteristics such as CEC, pH, soil particles and other factors. Therefore, aside from selecting the appropriate techniques to better understand microbial responses to metals, it is also important to understand the prevalent environmental conditions that interplay to bring about observed changes in any given soil parameter.
