Acid Mine Drainage (AMD) is a very common environmental pollution problem which occurs worldwide in mining region. AMD forms when sulphide minerals in rocks are exposed to oxidizing condition in coal and metal mining, highway construction and other large scale excavations. Water which drains naturally from coal and metal mine workings is often acidic with elevated heavy metal content, characterized with low pH and high alkalinity with elevated concentration of metals like Iron, Manganese and Aluminum. During mining, the exposed wall rocks come in contact with the oxygenated water, interaction between these causes generation of AMD. Bacterial activity also plays an important role in acid formation. Coal has a crucial role in meeting current needs and is a resource bridge to meet future goals through the enhancement of knowledge and technology. The challenge is to apply the right technology in the most efficient and environmentally friendly way. The biggest environmental challenge facing the coal industry is the issue of greenhouse gases and acid rain. Overall environmental management improvement has been taking place with the implementation of state of art environmental management schemes particularly under Environmental and Social Mitigation Project (ESMP) of CIL.Keywords

Free floating aquatic macrophyte namely Lemna minor (Linnaeus, 1753) was exposed to different concentrations of cadmium (1, 5 and 10 mg/L) for a period of 30 days to evaluate its cadmium (Cd) accumulation capability in the presence of chelating agents such as EDTA and citric acid. The chelating agents were added at the rate of 1, 2 and 3 mg/L separately and the experiment was conducted in triplicate. The water and plant samples were collected at 15 days interval for the analysis of cadmium. There was a significant difference in the Cd uptake (P<0.05) by the plant in the presence of chelating agents when compared to the control. Bioconcentration factor (BCF) of cadmium by the plants showed an increasing trend in the presence of chelating agents. The percentage uptake of cadmium by L. minor in the presence of EDTA was significantly higher than that of citric acid (P<0.05). The overall results suggest that EDTA can be effectively used to enhance phytoremediation efficiency of cadmium by L. minor in the contaminated water.Keywords

The present study was conducted to characterize arsenic resistant bacteria and to evaluate their arsenic remediation capacity. Water samples were collected from the shallow tubewell of Deganga, West Bengal. The arsenic content of shallow tubewell water was 45.07 μg/L. 16S rDNA analysis characterized the isolated arsenic resistant bacteria from the shallow tubewell water to be under the genus Pseudomonas and Acinetobacter. Minimum inhibition concentration (MIC) of arsenic for the selected bacterial isolates Pseudomonas sp. and Acinetobacter sp. was found to be 7 and 17.5 mM As(III), respectively. The selected bacterial isolates were capable of removing arsenic in the range of 1.54-5.95% from the nutrient broth supplemented with 25, 50, 75 and 100 mg/L As(III). Analysis of variance (ANOVA) indicated a significant difference (P<0.05) in arsenic removal between the arsenic concentrations, but there was no significant difference (P>0.05) between the selected bacterial isolates. The selected bacterial isolates could thus be useful for developing a technology for biological removal of arsenic by standardizing certain parameters for the optimum removal of arsenic by the selected bacterial isolates.Keywords

Objectives: In the present study, economic analysis of with and without periphyton substrate (aquamat installation) as treatment and control, respectively, was evaluated with semi-intensive culture (stocking density 20 numbers m-2) of Penaeus vannamei. Total duration of the culture was 120 days.
Methods/Statistical analysis: Economic parameters of both ponds were estimated via fixed cost, variable cost and gross revenues, and performance indicators such as benefit cost-ratio (BCR), net profit, break-even price, rate of return on investment, rate of return on operating cost, production per man day and contribution margin were calculated based on the profitability and the capital investment. The primary data was used for the calculation and the experiment was carried out in duplicates.
Findings: The capital investment for periphyton (US$ 23192, INR 62.5= US$) was higher than the control pond (US$ 17544). Higher production in periphyton pond resulted in the increased net income generation by 35.4 % than the control. Periphyton improves the economic return (US$ 18021; BCR – 2.3) of the semi-intensive shrimp farming and reduced the breakeven point (496) and feed cost (US$ 7426) of the culture pond. This indicates that the aquamat installation in semi-intensive shrimp culture system is a profitable venture and paves the way to attain sustainable intensification in the shrimp farming sector. The study was conducted on the field; it depicts the exact scenario of the profitability of aquamat installation when compared to the laboratory trial.
Application/Improvements: This technology also reduces and recycles the wastes, so it can also be applied as economically viable effluent treatment system for shrimp farming.
