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 most of iron, cement, paper and plastic related industries are running in Raipur area of the country. 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.

Polychlorinated Biphenyls (PCBs) exist in all compartments of the ecosystem due to wide industrial applications and production during burning processes. The PCBs congeners were quantified in the industrial, municipal and agricultural wastes of the most industrialized area of the country, Raipur city, India. The concentration of ΣPCBs in the sludge, sewage and agriculture wastes (n = 4) was ranged from 497 - 800 μg/kg with mean value of 634 ± 146 μg/kg. The PCBs congeners detected in the waste materials were ranged from 56 - 85 with mean value of 75 ± 13. The highest number of congeners was quantified in the sludge materials due to the existence of the heavy PCBs. The PCBs congeners were found to decrease vertically due to the adsorption by the geo-media. The distribution, sources and toxicities of PCBs congeners in the waste materials are discussed.

Coal is a dirty fuel contaminated with F- and other elements. Several million tons of coal are burnt in Korba basin, central India to generate electricity with pouring fluorine and other elements into the environment. The water is contaminated with F- and other chemicals beyond the permissible limits. The contaminated water is consumed by the human and animals by excreting the balanced toxicants through the stool and urine. Several folds higher concentration of F- in urine (44 mg/L) and stool (266 mg/kg) samples of the cattle are observed. The prevalence of fluorosis diseases in cattle of the Korba basin is reported.

Asbestos exposure is known to cause asbestosis i.e. lung cancer (mesothelioma) with increased risk of diseases i.e. gastrointestinal, colorectal, throat, kidney, esophageal, and gallbladder cancer. Therefore, in the present work, the concentration of SiO2 associated to the coarse and fine particulates in the ambient air of most industrialized area of central India i.e. Raipur city (capital of Chhattisgarh state) is described. The concentration of SiO2 in ambient air associated to the PM10 and PM2.5 was ranged from 6.6 to 102 and 0.2 to 15 μg/m3 with mean value of 30.0 ± 6.0 and 4.3 ± 0.8 μg/m3, respectively. The seasonal, spatial and temporal variations of SiO2 in the air are described.

The groundwater is widely used for irrigation of rice crops. The overuse of groundwater causes depletion of the water quality (i.e. enormous increase in conductivity, hardness and ion and metal contents, etc.) in several regions of the country and world. In this work, the quality of the groundwater in the densestrice cropping area, Saraipali, Chhattisgarh, Central India is discussed. The water is sodic in nature with extremely high electrical conductivity. The mean concentration (n = 30) of F-, Cl-, NO3-, SO42-, NH4+, Na+, K+, Mg2+, Ca2+ and Fe in the water was 1.2 ± 0.2, 98 ± 31, 46 ± 15, 56 ± 9, 19 ± 4, 206 ± 25, 9.2 ± 2.3, 39 ± 6, 114 ± 19 and 1.7 ± 0.6 mg/L, respectively. The sources of the contaminants are apportioned by using the factor analysis model. The suitability of the groundwater for the drinking and irrigation purposes is assessed.

Environment in India is contaminated with polycyclic aromatic hydrocarbons (PAHs) due to occurring of large anthropogenic activities i.e. fuel combustion, mineral roasting and biomass burning. Hence, contamination of 13 toxic PAHs: phenanthrene, anthracene, fluoranthene, pyrene, benz (a) anthracene, ben-zo (b) fluoranthene, benzo (k) fluoranthene, benzo (a) pyrene, benzo (ghi) perylene, dibenz (ah) anthracene, indeno1,2,3-(cd) pyrene, coronene and coronene in the environment (i.e. ambient particulate matter, road dust, sludge and sewage) of the most industrialized area: Raipur city, India is described. The ΣPAH13 concentration in the 16 environment materials was ranged from 7980 - 1,051,300 μg/kg with mean value of 172,613 ± 154,726 μg/kg. The concentration variations, toxicities and sources of the PAHs in various environmental compartments are discussed.

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.
