In this work, the contamination of F- in the environment (i.e. water, soil, rock and urine) of the Tamnar block is described. The concentration variations of F-, Cl-, NO3-, SO42-, Na+, K+, Mg2+, Ca2+, Al, Mn, Fe and Zn in the groundwater are reported. The F- content in the water was ranged from 1.7 - 17 mg/L with mean value of 9.0 ± 3.7 mg/L. Fluoride was enriched up to 3-, 54-, 69- and 244-folds in the urine, soil, dust and rock, respectively. The cluster and factor analysis models were used to apportion sources of F- and other elements in the water.展开更多

They use a large amount of water by discharging effluents into the streams and rivers by polluting nearby water resources. In this work, the physico-chemical characteristics of discharged waste water of 34 industries (i.e. iron, steel, power, paper and polymer) are described. The waste water is found to be acidic in nature with high contents of F- and other ions.展开更多

However, vegetables in industrial area are getting contaminated with heavy metals by disturbing biological and biochemical processes in the human body. In present study, the risk of human health by heavy metals (Fe, As, Cr, Mn, Cu, Zn, Pb, Cd and Hg) through the intake of common vegetables i.e. Solanum lycopersicum, Solanum melongena, Amaranthus tricolor L., Chenopodium album L., Spinacia oleracea and Coriandrum sativum obtained from the largest coal burning basin, Korba, India is described . The concentration of Fe, As, Cr, Mn, Cu, Zn, Cd, Pb and Hg in the soils (n = 6) was ranged from 18,328 - 37,980, 85 - 105, 34 - 72, 314 - 760, 146 - 165, 126 - 164, 1.11 - 1.39, 116 - 148 and 0.11 - 0.21 mg/kg with mean value (p = 0.05) of 28,011 ± 6582, 96 ± 6, 57 ± 11, 597 ± 148, 153 ± 5, 145 ± 11, 1.26 ± 0.10, 133 ± 11 and 0.16 ± 0.03 mg/kg, respectively. The contamination, sources and bioaccumulation, pollution and health risk indices of the heavy metals i.e. As, Fe, Cr, Mn, Cu, Zn, Pb, Cd and Hg in the plants are described.展开更多

In this work, the contamination of tree leaves with the HMs in the most polluted industrial city, Korba, India is described. The leaves of common trees i.e. Azadirachta indica, Butea monosperma, Eucalyptus, Ficus religiosa, Mangifera indica and Tectona grandis were selected for assessment of the HMs contamination as bioindicator. The elevated concentration of HMs (i.e. As, Fe, Cr, Mn, Cu, Zn, Cd, Pb and Hg) in the tree leaves was observed, ranging from 2.8 - 43, 728 - 5182, 8.6 - 49, 48 - 1196, 43 - 406, 79 - 360, 1.12 - 1.65, 1.6 - 16.4 and 0.13 - 0.76 mg/kg, respectively. The concentration, enrichment and sources of the HMs in the leaves are described. Azadirachta indica leaves, accumulating higher concentration of the HMs, showed a higher efficiency as bioindicator for the urban pollution.展开更多
