In India, several (>50) vegetables are widely used as food due to their high nutrition values. 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.

The basic bed rocks of central India are contaminated with fluorite minerals. The overuse of groundwater for irrigation causes increased mineralization of F- in the groundwater. This contaminated groundwater is widely used for drinking and other household purposes. The excess F- is excreted through urine of animals. In this work, the exposure of contaminated groundwater in domestic animals of Dongargarh city, Chhattisgarh, India is studied. The symptoms of fluorosis diseases in the domestic animals i.e. cattle and buffalo are surveyed. The quality and sources of the contaminants of the groundwater are discussed.

Two major issues, i.e. large crop productions and huge anthropogenic activities (e.g. fuel burning and mineral roasting) disturb the micronutrient balance in the soil of India. In this work, the available and total status of eight micronutrients i.e. Fe, Mn, Cu, Zn, Co, Ni, Mo, and S of the soils in the most urbanized area: Raipur area, Chhattisgarh, India (extending over ≈ 2 × 104 km2) is described. The available status of micronutrients i.e. Fe, Mn, Cu, Zn, Co, Ni, Mo and SO42- in the soils (n = 100) was ranged from 30 - 8253, 205 - 2800, 2.0 - 8.1, 0.7 - 5.0, 2.2 - 31.2, 0.1 - 13.4, 0.1 - 8.9 and 41 - 747 mg/kg with mean value of (at 95% probability) 642 ± 186, 1178 ± 119, 4.3 ± 0.3, 2.3 ± 0.2, 12.8 ± 1.3, 3.9 ± 0.6, 1.5 ± 0.3 and 281 ± 25 mg/kg, respectively. The concentration variations, deficiencies and toxicities of the micronutrients in the soil are discussed.

The study of heavy metal (HMs) contamination of environment is of great interest due to their serious health hazard. 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.

The road dusts (RD) are fugitive in nature causing potential health hazards to people living in highways. They are generated from different sources on the roads and being a valuable archive of environmental information. In the present work, contamination assessment of 18 heavy metals and ions in road dusts of the country are described. Techniques i.e. ion selective, ion chromatography and atomic absorption spectrophotometers were used for analysis of the ions and metals. The content of F-, Cl-, , , , Na+, K+, Mg2+, Ca2+, As, Cr, Mn, Fe, Ni, Cu, Zn, Pb and Hg in the road dusts was ranged from 75 - 895, 276 - 12718, 48 - 1423, 243 - 10,580, 11 - 539, 290 - 46,484, 110 - 7716, 84 - 1771, 595 - 15,955, 24 - 42, 164 - 526, 1711 - 5218, 63,850 - 144,835, 47 - 62, 81 - 720, 166 - 450, 92 - 295 and 0.05 - 0.12 mg/kg with mean value of 224 ± 43, 3734 ± 895, 592 ± 895, 2859 ± 662, 143 ± 29, 4826 ± 2049, 1565 ± 411, 837 ± 121, 8545 ± 1288, 31 ± 4, 246 ± 82, 3002 ± 851, 91,331 ± 18,587, 54 ± 4, 206 ± 145, 241 ± 64, 171 ± 42 and 0.08 ± 0.02 mg/kg, respectively (at 95% probability).

The stagnant water reservoirs in urban area of India are severely contaminated with surfactant and microbe due to anthropogenic activities. In this work, water quality of pond water of the most industrialized city: Raipur, CG, India is described. The concentration of surfactant in the term of sodium lauryl sulfate (SLS) in water (n = 16) is ranged from 7.0 - 27 mg/L with mean value of 17 ± 3 mg/L. All ponds are found to be contaminated with microbes i.e. bacteria, algae and fungi at elevated levels. The physico-chemical characteristics of the pond water are discussed.

Raipur is a fast growing city in central India due to being commercial centre for the steel, cement and forest products of the country. Large quantity (≈300 million lit/day) of untreated sewage waste water is discharged into seven reservoirs located in the city. Sewage carries excessive nutrients, heavy metals, organics, bacteria, yeast and fungi by leaking contents into the drinking water which cause acute health problems, ranging from common diarrhoea to deadly diseases such as hepatitis, cholera, typhoid fever, etc. Therefore, in this work, the microbial and chemical contamination of sewage waste of Raipur city, Chhattisgarh, India is described.

At least 15% of 0.1 million people residing in 117 villages of Tamnar block (Chhattisgarh, central India) are suffering from fluorosis diseases. 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.
