Groundwater samples were collected from several places of Chikiti Block in Ganjam district to analyze their hydrochemistry so as to ascertain their suitability for drinking and agricultural use. In addition to TDS (total dissolved solids), the concentration of several ions such as Ca2+, Mg2+, Na+, K+, HCO3-, CI-, SO4-2, NO3-, PO43-, CO32-, F- and Fe2+ were determined. Analysis results showed that the concentration of all the major ions were well within their limiting values as recommended by World Health Organization (WHO). The TDS is also within the recommended limiting values. It is found that the water is completely fit for its use as drinking and agricultural purposes. However, during the pre-monsoon seasons, one or two places exhibited higher TDS values thus making it imperative to use more of surface water so that pressure would be lessened on groundwater resources.

An estimated 1.2 million scavengers in the country are involved in the sanitation of our surroundings. The working conditions of these sanitary workers have remained virtually unchanged for over a century. Apart from the social atrocities that these workers face, they are exposed to certain health problems by virtue of their occupation. These health hazards include exposure to harmful gases such as methane and hydrogen sulfide, cardiovascular degeneration, musculoskeletal disorders like osteoarthritic changes and intervertebral disc herniation, infections like hepatitis, leptospirosis and helicobacter, skin problems, respiratory system problems and altered pulmonary function parameters. This can be prevented through engineering, medical and legislative measures. While the engineering measures will help in protecting against exposures, the medical measures will help in early detection of the effects of these exposures. This can be partly achieved by developing an effective occupational health service for this group of workers. Also, regular awareness programs should be conducted to impart education regarding safer work procedures and use of personal protective devices.

Indian J occup envir Med 2008, 12(3), 132-5.
In a cross-sectional study, a random sample of 197 male workers drawn from different sections of 10 leather tanneries in Kanpur were selected for the assessment of health risks. A control group comprising of 117 male subjects belonging to a similar age group and socioeconomic strata, who never had any occupational exposure in the leather tanneries, were also examined for the comparison purpose. The findings revealed a significantly higher prevalence of morbidity among the exposed workers in contrast to that observed in the controls (40.1% vs. 19.6%). The respiratory diseases (16.7%) were mainly responsible for a higher morbidity among the exposed workers whereas the gastrointestinal tract problems were predominant in the control group. The urinary and blood samples collected from the exposed group showed significantly higher levels of chromium, thereby reflecting the body burden of Cr in the exposed workers as a result of a high concentration of environmental Cr at the work place.

Pollut Res 2008, 27(2), 247-52.
In this modern world of advanced techniques, sewage treatment works are considered to be one of the most popular procedures carried out to use the treated wastewater for agricultural purposes or to dispose off on to the land. The primary objective of this study is to design a Sewage Treatment System for Sri Satya Sai Urban Development Authority (SUDA) in A.P and studying the possibilities for usage of treated wastewater for irrigation. The study area, Puttaparthy being a pilgrim center attracts people all over the world and during some special occasions the place gets over crowded. Hence, sewage treatment units were designed specially keeping in view of the peak population. In the present study, design of the various sewage treatment units like screens, grit chambers, primary settling tanks, trickling filters, secondary settling tanks, sludge digestion tanks, sludge drying beds were carried out. Puttaparthy and its surrounding areas come under drought prone areas of Anantapur district. Hence large numbers of people are migrating for works due to lack of irrigation water for growing of crops. Hence, the treated wastewater of SUDA can be used effectively for raising some suitable crops in that area. The National Water Policy of India also emphasizes the need for recycling and reuse of wastewater.

Studies on biosorption of zinc (Zn) from synthetic solutions using Staphylococcus aureus were carried out. Staphylococcus aureus showed a very high capacity of biosorption (60.17 ppm Zn mg-1 dry biomass) of Zn from synthetic solutions. Biosorption of Zn was rapid and was dependent on pH and the quantity of biomass used. The influence of increase in the quantity of biomass from 1 mg per mL to 5 mg per mL of Zn from synthetic solutions was also studied. However further increase in biomass of Staphylococcus aureus decreased the biosorption of Zn. Effect of magnesium chloride (MgCl2) on biosorption was also studied. Addition of MgCl2 was found to enhance the biosorption of Zn. Nutrient deficient conditions inhibited Zn biosorption from synthetic solutions by Staphylococcus aureus.

Tehri hydroelectric project of 2,400 MW capacity, the Asia's highest dam constructed on the Bhagirathi river in Uttarakhand is one of the most debatable dams of the country. The fluvial system of Bhagirathi and Bhilagana has been converted into a huge lentic water reservoir of 2.62x109 m3 capacity. Therefore, the information on periphytonic diversity before impoundment is very important. The preimpoundment study over one year (September 2004 - August 2005) was carried out monthly to analyse the periphytonic diversity in a lotic environment of Bhagirathi, one of the parent streams of Ganges. Periphytons are the important primary producers of metarhithronic stretch of Bhagirathi. 40 taxa of periphytons, represented by the families of Bacillariophyceae (25 taxa), Chlorophyceae (11 taxa) and Myxophyceae (4 taxa), were recorded from the Bhagirathi river before impoundment. The Shannon-Weiner diversity index ranged between 3.404 to 4.360 for periphytons, which indicates a good health of the ecosystem. The present study revealed that the combined impact of velocity of the water, hydromedian depth (HMD), turbidity, dissolved oxygen, total dissolved solids (TDS), and water temperature influenced the diversity of periphytons dwelling Bhagirathi.

Microbial consortium was developed by continuous enrichment of bacterial population isolated from sediment core of tannery effluent in mineral salts medium (MSM) supplemented with pentachlorophenol (PCP) as sole source of carbon and energy in the chemostat. The enriched consortium contained 3 bacterial strains identified as Escherichia coli (PCP1), Pseudomonas aeruginosa (PCP2) and Acinetobacter sp. (PCP3) by morphological and biochemical tests, further confirmation was done using 16S rDNA sequence analysis. The strains were tested for their utilization of various organic compounds. The strain PCP3, showed higher potency to utilize PCP as sole source of carbon and energy than PCP1 and PCP2. The bacterial strain were able to utilize PCP through an oxidative and reductive route as indicated with the formation of tetrachloro-p-hydroquinone (TeCH), 2-chloro-1,4-benzenediol and 2,3,4,6-tetrachlorophenol. The enriched strains could possibly be used for bioremediation of sites contaminated with PCP.

The study related to assessment of various chemical constituents in the groundwater, their origin and suitability for human use has been carried out in the Chaliyar river basin of Kerala (India). Groundwater samples were collected from 27 open dug wells and 7 bore wells, and analyzed. Piper tri-linear classification was followed in segregating the data with respect to source of dissolved constituents in groundwater. Most of the wells fall within the no dominant ion zone in the piper diagram, indicating the equal distribution of alkalis and alkaline earths. High level of dissolved solids, with the presence of chloride and sulphate, was observed in a few wells in the coastal region, which may be due to the salinity intrusion from the sea. The groundwater quality was found fairly good and potable in the lateritic midland region, except for a few wells, which were having significant level of nitrate and/or chloride. An attempt has been made to understand the source of groundwater recharge in the basin using environmental tritium as a tracer. It has been observed that the groundwater is predominantly recharged through rainfall, as evidenced from the level of tritium close to that of local precipitation.

Water quality monitoring of a central Himalayan river, river Kosi was done for a period of one year. The study was done to ascertain the suitability of its water for potable supplies and to generate benchmark data for the management of the river ecosystem, as the river has a great bearing on the socio-agricultural life of the region. Fifteen physicochemical and two biological parameters were analyzed. The data suggest that river is under stress of anthropogenic activities. Many of the water quality parameters viz., pH, DO, BOD, COD and Fe exceed the WHO (1971) norms of water quality. The study suggests high anthropogenic activities along the catchment of the river, and the high amplitude of these activities at sampling stations manifested proves water quality of that site.

Indian J Physiol Pharmac 2008, 52(1), 84-90.
Effect of arsenic was studied on the testicular tissue of Swiss albino mice. Sodium-meta-arsenite (NaAsO2) was administered to adult mice (25±30g) at a dose level of 30 mg/L and 40 mg/L through drinking water for 30, 45 and 60 days. After the treatment, the testicular organ was removed, weighed and processed for histopathological observation. No change in the body weight was recorded in treated groups after arsenic exposure but significant decrease in the relative testicular weight was observed in comparison with the control. The result showed that arsenic-treated mice exhibited dose dependent gradual reductions in seminiferous tubular diameter and various gametogenic cell population i.e. resting spermatocyte, pachytene spermatocyte and step-7-spermatid except spermatogonia. Leydig cell atrophy was significantly increased in dose dependent manner indicating a definite effect of arsenic on the spermatogenesis in mice. These observations were supported by gradual reduction in Leydig cell population in the above treated groups. In conclusion, the above results confirm the toxic effect of arsenic in testis of mice.

Res J Chem Envir 2008, 12(3), 23-34.
The ability for heavy metals removal by C. odorata and V. zizanioides grown on contaminated soil and synthetic contaminated soil in experimental pots was investigated. Both contaminated and uncontaminated soils, for preparing the synthetic contaminated soil in this study, were obtained from Mae Sot district, Tak province. The contaminated synthetic soil was prepared by adding a solution of cadmium nitrate, zinc sulfate, lead nitrate and copper sulfate to uncontaminated soil to make the concentration of each metal: Cd, Zn, Pb, and Cu 100 mg/kg soil above its initial concentration. In both plants grown on-site contaminated soil and on the synthetic soil, although some abnormal symptoms such as chlorosis, scorching in leaves and necrosis appeared, the plants still grew well. Each part of the plant was examined for heavy metal uptake at 30, 60, 90 and 120 days after planting. Root uptake was greater than that of stem and leaves in all samples. For the on-site contaminated soil, the highest concentrations found in the root part for Cd, Zn, Pb and Cu of C. odorata were 50.22, 123.45, 29.07 and 31.89 mg/kg on a dry weight basis respectively and of V. zizanioide were 11.24, 163.18, 40.63 and 15.62 mg/kg on a dry weight basis respectively. The synthetic contaminated soil plants also showed higher concentration in root part than the other two parts for all metals both in C. odorata and in V. zizanioide. This is due to the metals being present in a readily available form. Accumulation of Cd in mass for both plants grown in contaminated soil at the time of harvesting showed that C. odorata performed better than V. zizanioide, especially for the aboveground parts and the time for harvesting that yielded the highest uptake of Cd was at 120 days.

Cr (VI) (Chromate) is a toxic, soluble environmental contaminant. Bacteria can reduce chromate to the insoluble and less toxic Cr (III), and thus chromate bioremediation is of interest. Several bacteria possess chromate reductase activity than can convert chromate to Cr (III), which is much less toxic and less soluble and thus reduction by these enzymes affords a means of chromate bioremediation. In this work, purified and characterized Chromate reductase from Pseudomonas putida using stepwise procedure consisting of [NH4]SO4 precipitation, anion exchange chromatography (DEAE sepharose CL-6B) and gel filtration (Sephadex -G-25). The enzyme activity was dependent on NADH or NADPH, the temperature and pH optima for chromate reduction were 75

Lead is one of the most useful elements in industry, but serves no useful function in the human body. Environmental and industrial lead exposures continue to pose major public health problems in the exposed population. Over the years, it has become increasingly evident that low-level lead exposure resulting in blood lead levels between 10 and 15 μg/dL can lead to deleterious effects like cognitive impairment and behavioral deficits, high blood pressure (BP) and impaired renal function. Lancereaux provided the first description of kidney disease and interstitial nephritis by postmortem examination of a lead-poisoned artist. It was not until the late 1920s when an epidemic of chronic nephritis in Queensland, Australia, was linked to childhood lead poisoning that the full spectrum of lead-induced nephropathy became apparent. This was followed by cases of renal diseases from the US in individuals consuming lead-contaminated illegally distilled moonshine whisky.

Workers of iron and steel factories are exposed to a wide range of pollutants depending on the particular process, the materials involved, the effectiveness of monitoring and the control measures. Adverse effects are determined by the physical state and propensities of the pollutant involved, the intensity and duration of the exposure, the extent of pollutant accumulation in the body and the sensitivity of the individual to its effects. The main aim of this study is to assess the levels of the indoor respirable particulate matter (RPM) and to compare the health condition of exposed workers, with nonexposed employees group. Line 630 has only one furnace of 40 tons and line 650 has two furnaces of 20 and 40 tons capacity due to which the mean of the RPM concentrations in the breathing zone was significantly different (P < 0.05) in line 650 but not in line 630 as compared with National Institute for Occupational Safety and Hygiene's (3 mg/m3). The average of the RPM concentrations in production line 650 is higher than that of production line 630, with the 95% confidence interval in saw cabin station number 1 of production line 650.

Study was under taken to work out the impact of vehicular pollution on the pigment content of four plant species namely- Alstonia scholaris, Ficus religiosa, Nerium odorum and Polyalthia longifolia growing at different road sides with varying number and type of plying vehicles and also to observe, if any, correlation exists between the two. For this, leaf samples from different sites of the above-referred species were collected and analyzed for leaf extract pH, chl.a, chl.b, total chlorophyll, carotenoid and protein content. Leaves were sampled from all the four directions and from almost equal heights of the plants. All the parameters registered a definite reduction with the increase in vehicular density in comparison to the control (least polluted) site. However, no definite trend was seen in case of the leaf extract pH. Thus, the study pinpoints a possibility of using these modifiable parameters as traits to be used as biological indicators of pollution loads in the city.

Electronic waste or e-waste is one of the rapidly growing problems of the world. E-waste comprises of a multitude of components, some containing toxic substances that can have an adverse impact on human health and the environment if not handled properly. In India, e-waste management assumes greater significance not only due to the generation of its own e-waste but also because of the dumping of e-waste from developed countries. This is coupled with India's lack of appropriate infrastructure and procedures for its disposal and recycling. This review article provides a concise overview of India's current e-waste scenario, namely magnitude of the problem, environmental and health hazards, current disposal and recycling operations, existing legal framework, organizations working on this issue and recommendations for action.

The industrial development and growing population in India is in demand of more energy. Coal based thermal power generation is a major source of energy and is expanding at a very high rate leading to over exploitation of coal reserves, which is causing adverse impacts on the environment. Remote sensing and GIS techniques have been found to be useful in mapping and monitoring of dynamic changes taking place due to mining activity. Satellite based environmental impact assessment involves various aspects, such as land use, water resources, land degradation, etc. These studies help in formulating environmental management plan for the mining sector. Coal mines in Erai watershed of Chandrapur district so far have lost 2139.68 hectares of land constituting a fertile agriculture land, reserve forest, protected forest and natural river course of Erai river, Upsa nala and Motaghat nala severely affecting the watershed eco-system. Therefore, an in-depth impact assessment study of coal mines in Erai watershed of Chandrapur district was carried out using geoinformatics and the results are presented in this paper.

This paper presents a detailed computational fluid dynamics (CFD) based approach for modeling thermal destruction of hazardous wastes in a circulating fluidized bed (CFB) incinerator. The model is based on Eular - Lagrangian approach in which gas phase (continuous phase) is treated in a Eularian reference frame, whereas the waste particulate (dispersed phase) is treated in a Lagrangian reference frame. The reaction chemistry has been modeled through a mixture fraction/ PDF approach. The conservation equations for mass, momentum, energy, mixture fraction and other closure equations have been solved using a general purpose CFD code FLUENT4.5. Afinite volume method on a structured grid has been used for solution of governing equations. The model provides detailed information on the hydrodynamics (gas velocity, particulate trajectories), gas composition (CO, CO2, O2) and temperature inside the riser. The model also allows different operating scenarios to be examined in an efficient manner.

An oil spill was simulated in microcosms in the laboratory using phytoplankton assemblage collected from Versova, Mumbai. Bombay High Crude oil (1%, w/v), water-soluble fraction (0.01%, w/v) and water-dispersed fraction (0.01%, w/v) were added to respective tanks. Their effect was investigated on various parameters like primary productivity, growth and biomass of the phytoplankton at different time intervals. There was reduction in primary productivity and cell number resulting in decreased biomass after 6 h, 24 h and 48 h. Net as well as gross productivity was less in tanks treated with water soluble and water dispersed fractions. Soluble fraction was more toxic than dispersed fraction of crude oil as it caused drastic reduction in cell count within 1 h. These results indicate that the above-mentioned levels of oil contamination in seawater are not having an immediate and serious detrimental effect on the photosynthesis of the natural phytoplankton communities.

The Burnpur IISCO (Indian Iron and Steel Company) slag disposal site which is located in West Bengal, India at 23° 40' ON latitude and 86° 55' 60E longitude, about 5 km away from Asansol has been characterized in the present study with respect to its physicochemical and biological aspects. The pH, BOD, COD, DO, alkalinity and water holding capacity etc have been determined and are found to be unsuitable for the growth of normal vegetation. However, these parameters vary widely in fresh released slag and the slag which has been dumped for a long time. This may be due to microbial and chemical activities inside the slag. The microbial diversity as determined by the species richness method was found to be 0.408 and 1.028 for the fresh and the old slag. The meteorological data of the area indicates that the average annual rainfall, average annual temperature (max. and min) and average annual humidity etc. are nearly 1400mm, 33.82 ° C (max) and 20.70 °C (min) and 63.82% respectively. However, the maximum and minimum temperatures reach to 49° C in summer and 5 °C in winter respectively. The vegetation is quite different from nearby normal flora with maximum frequency of Eragrostis and Eupatorium and minimum of Euphorbia hirta, Evolvulus, Calotropis etc.

The trace metal levels were studied in soil and water of Tipong, Tirap and Tikak Collieries of Makum Coal Field, Tinsukia, Assam. The toxic trace metals viz Cadmium (Cd), Copper (Cu), Lead (Pb) and Zinc (Zn) were analyzed using Atomic Absorption Spectrophotometer (AAS). Pb was found to be below detectable level (BDL) in both the soil and water samples. The metals Cd, Cu and Zn were found in water samples while Cd and Zn were found in the soil samples. The highest amount of Cd (0.127ppm) & Zn (0.157ppm) were detected in water samples of Tipong colliery and the concentration of both the metals were found to be present above the permissible level while other two metals (Pb and Cu) were under the permissible level as recommended by WHO (1985). The highest amount of Cd (44 ppm) & Zn (249ppm) in soil samples were detected in Tirap and Tipong colliery. On the basis of results obtained, it is clear that continuous mining operation have left permanent scars in the coalfield environmental scenario to a large extent.

Sediment core samples were collected at nine stations in the coastal Peninsular Malaysia using a box corer for estimation of sedimentation rates based on the contents of 210Pb, 226Ra and 228Ra in bulk sediments. The core sediments were generally composed of homogenous mud especially in the west coast Peninsular Malaysia (Malacca Straits) sampling stations. Sedimentation rates calculated using models of 210Pb, 226Ra, 228Ra and 210Pb/226Ra ratios fluctuated in the range 0.20-0.42, 0.08-0.44, 0.12-0.45 and 0.06-0.45 cm year-1 respectively, with highly sedimentation rate for the stations located in the Malacca Straits. The geography of Malacca Straits was a closed system where the water flows, in general, come from the north to the south during monsoon season and received also large input from the Sumatra Island in Indonesia and the west coast of Peninsular Malaysia. But in the east coast Peninsular Malaysia (Sunda Shelf) sector had influence from the northeast and southwest monsoon, and input also from the western Pacific region.

Global warming, caused by accumulation of green house gases (GHG) in atmosphere has wreaked serious catastrophe on mankind in terms of intense rain, devastating hurricanes, drop in grain production and deluge of land mass under swollen seas due to erratic weather behavior. It has serious impact on livestock production too. The resurgence of blue tongue disease in cattle is believed to be a sequel to global warming. Strangely, livestock is also a partner to this crime through emission of green house gases like carbon dioxide, methane, nitrous oxide and ammonia to the atmosphere, which constitute 18% of the total GHG in terms of CO2 equivalent. De-carbonation of the atmosphere by moderating animal production is not a pragmatic solution because of its enormous economic impact on food production sector. Livestock is the life-line of 92 million impoverished people of third world nations. Livestock constitute 40% of the total global agricultural output, and contribute 654 million metric tons of milk and 271.3 million metric tons of meat per year to the global food pool, besides generating employment for 1.3 billion people in the rural sector. Therefore, diminution of GHG emission through tactical livestock management and siphoning of CO2 from the atmosphere through carbon sequestration are the best options to resist this menace.

Sampling was conducted at National Environmental Engineering Research Institute (NEERI), Ajni Square and laxmi Nagar Square in terms of PM10 and benzene-soluble organic fraction (BSOF). Thirty two samples were collected at each location on 24 hr basis during post-monsoon and winter season (2005-06). The collected PM10 samples were subjected to determination of toxic organic fraction by measuring BSOF. The average PM10 concentration during the post-monsoon season was observed to be 98± 18, 120±11 and 107±11μg/m3, respectively and during the winter season 120±20, 135±13 and 129±13 μg/m3, respectively. Similarly the average BSOF concentration was observed to be 28±21, 31±11 and 29±12 μg/m3 for post-monsoon and 32±25, 33±13 and 31±10 μg/m3 for winter season, respectively. The result shows that the concentration of PM10 and BSOF is higher in winter season than post-monsoon season because during winter season atmospheric stability built up pollutant in the atmosphere. The study indicates that the air quality of Nagpur city exceeding the Central Pollution Control Board (CPCB) standards of PM10 which any be attributed to terrestrial and anthropogenic sources. In PM10, BSOF is exceeding the limit of 20μg/m3 indicating high levels of organic compounds including PAH. The study focuses the environmental quality of organics concentration available in ambient air and helps to generate baseline data to tackle the air pollution problems and implement effective regionbased control measures.

Damages caused by an intraocular foreign body (IOFB) to the visual system, mainly the retina, mostly occur during certain occupational activities. Turners are among the laborers who are mostly exposed to IOFB. The aim of the present work is to survey the effect of an IOFB on the visual system, mainly the retina. Fifty laborers of a turner factory who were exposed to IOFB were selected. Electroretinography (ERG) was recorded in all the laborers. Beside these workers, 50 laborers with no incidence of IOFB were also selected. They were also tested using ERG. The results obtained in the two groups were compared together to search for the possible changes in the two groups. The ERG patterns of the case groups were found to be changed in comparison to the control group. The changes were observed in the area under the b-wave of the ERG pattern in the early stage of damage and in the late stages, the latency and amplitude of the ERG b-wave were also affected. Finally, from the result of the present study, one can conclude that ERG is a suitable technique to search for the retinal changes in the laborers exposed to IOFB.

Dhaka city produces tonnes of solid wastes everyday. Dhaka City Corporation (DCC) does not have any sanitary landfill for ultimate disposal of solid waste and for a long time it is a common practice of DCC to dispose off solid waste in open low lying areas without any segregation and soil cover. Matuail is one of the disposal sites operated by DCC and has been selected as the study area in the present research. Solid wastes and soil samples (normal and converted) at different depths were collected from the site and analysed in the laboratory to assess the potential contamination due to this dumping. This study was an attempt to investigate the characteristics of solid wastes and pollution level in natural and converted soil and surface water in the study area. Test results shows that the solid waste disposed at Matuail dumping site contains significant amount of heavy metals such as iron, manganese, copper, zinc and nickel. The concentration of heavy metals in converted soil is much higher than the natural soil in the dumping site. This indicates that the converted soil, which is formed due to dumping of wastes over the years is highly contaminated with toxic metals. The concentration of heavy metals such as cadmium, lead, copper and zinc in converted soil are significantly higher than the maximum allowable limits of the concentration of those heavy metals used in different countries. The high concentration of heavy metals in converted soil may lead to groundwater pollution in future. Surface water around the disposal site has been found to be highly polluted which indicates an unhealthy environment for aquatic life. The high concentration of colour, BOD5, COD, TC, FC, Pb, Cu, Zn etc. shows that the water is not suitable for domestic use. The presence of such hazardous toxic metals in waste, soil and surface water is a great concern of public health and the surrounding environment (soil, groundwater, surface water).
