Total and individual chlorophylls, a and b, total water soluble carbohydrates and dry weight of Triticum aestivum var. Malvia-212 were determined following the treatment with different concentrations of the sugar factory wastewater. Concentrated effluents showed marked effect and reduced these contents significantly which may be attributed to the reduced number of leaves and leaf area. The reduced growth and biomass are result of high concentration of soluble salts and heavy metals present therein, which possibly interfere with the absorption of water and minerals.

Effect of industrial effluent of a brewery industry of Ghaziabad was evaluated on the seed germination, seedling elongation, fresh and dry weight of Capsicum annuum cultivar, P. Jawala. Four different concentrations i.e. 100%, 75%, 50% and 25% were used for treating the seeds either directly or after pre-soaking of seeds in distilled water. In general, the effluent had promotry effect on seed germination and this enhancement was inversely proportional to effluent concentration and duration of treatment to certain extent. The effluent promoted the fresh and dry weight was probably due to absorption and accumulation of substances present in the effluent.

Since a long time, the Sabarmati river, which passes through the center of Ahmedabad has been subjected to severe pressure and abuse owing to the fast pace of urban and industrial growth of the city. Sewage contamination, storm water outfalls and the dumping of industrial wastes pose a major health and environmental hazard. Though the river banks and bed provide a place to stay and a source of livelihood for many poor citizens, the river bank slums are disastrously flood prone and lack basic infrastructure services. The following five localities of Sabarmati river basin from Gandhinagar to Ahmedabad were studied as a part of research i.e. Nabhoi village, Indira bridge, Subhas bridge, Nehru bridge and Sardar bridge. Excess heavy metal accumulation in sediment is toxic to humans and acute, immediate poisoning from heavy metals is rare through ingestion or dermal contact. Iron content of water samples from all localities are within the permissible limit of BIS except locality no. 3, 5 in winter, locality no. 2, 3 and locality no. 1, 2, 3, 4 in monsoon. Zinc, Copper and manganese content of water samples from all localities are within the permissible limit of BIS. Iron content of sediments samples from all localities is higher than the permissible limit of BIS. Zinc content of sediments samples from all localities are higher than the permissible limit of BIS except locality no. 1, 2 in winter and summer and no. 1,2,3,4,5 in monsoon. Copper content of sediments samples from all localities are higher than the permissible limit of BIS except locality no. 1 in winter, summer and monsoon. Manganese content of sediments samples from all localities are higher than the permissible limit of BIS except locality no. 1,2,3,4, 5 in monsoon. Results suggested that water is not suitable for drinking and sediments are highly polluted due to heavy metals.

Ecol Envir Conserv 2008, 14(4), 567-70.
The increase in population and urbanization has resulted in the production of huge amount of wastewater. The problems of sewage water disposal can be solved only by effective utilization of this wastewater for agricultural irrigation. But heavy metals like zinc, cadmium, silver, arsenic etc., are present in the sewage. If the untreated sewage water is used for irrigation, the heavy metals directly affect the soil properties and accumulate in the irrigating crops. It directly affects the human health when it is consumed. Therefore, the sewage water can be used for irrigation purposes for the cultivation of non-edible plants like flowering plants. The present investigation was carried out to find out the irrigational response of sewage water on growth and yield of African mariegold (Tagetes errecta L). Field experiments were conducted with African mariegold by irrigating the sewage water as well as well water (control). The various morphological growth parameters such as root length, shoot length, number of branches, number of leaves, total leaf area and their dry weight were recorded at 30,60 and 90 days after sowing (DAS). The yield param eters viz., number of flowers per plant, flower yield, flower diameter and 100 flower weight were recorded at 90 DAS. The study reveals that flowering plants had the greater growth rate and yield in sewage water irrigation when compared to control.

Malathion, a pesticide in the organophosphate chemical family is the most commonly used pesticide in our country. Symptoms of exposure to malathion include headache, nausea, vomiting, burning in eyes, difficulty in breathing and lethargy. Earthworms have been used as biomarkers for assessing chemical environmental pollution. Due to their low cost, easy handling, their direct body contact with the soil and ethical issues related to mammalian studies, earthworms were chosen for the present study. Three doses of malathion 150, 300 and 600 mg/kg soil were used as treated soil. The effect of application of malathion on the earthworm Lampito mauritii was studied for 5,10,15 and 30 days exposure by evaluating the body weight, number of cocoons laid and the hatching efficiency of the cocoons. The results showed that there is a direct dose response relationship with respect to both, the concentration and time of application of malathion. The results have been statistically analysed.

Eutrophication is a vital issue in India due to unsafe disposal of domestic wastewater containing Phosphorous (P) in water bodies. On the background use of Constructed Wetlands in U.S. and European countries, it seems to be an attractive option to hinder such pollution. In this context, a pilot unit consisting Typha latifolia and stone grit bed media was studied in a batch mode for P - removal in comparison with reference unit. In this study, the batch CWTS demonstrated 4% to 23% P removal during HRT of 1.5 to 7.5 days due to adsorption and plant uptake mechanisms. The Typta plants were found to have uptake of 147.89 kgP/ha.year. The P adsorbed was found to be 0.02 mgP/g stone grit used as bed media during four months of study. The technique may prove to be a viable treatment option for the treatment of P rich wastewater, with further research related with evaluation of different media and wetland plants for their potential application in batch type constructed wetlands.

Environmental Impact Assessment concept in India came in the year 1994 and amendment in the notification about three times is the clear indication that concerned people and organization are not taking a breathe after introducing Environmental Impact Assessment in India. They are constantly monitoring and taking corrective action to make this Environmental Impact Assessment concept a real working tool to protect the environment. Recognition of EIA consultant and organization through "quality Council of India''/NRBPT cell is also one step ahead to stop entry of unethical people mushrooming as EIA consultant. In view of the impacts that the Hydal Power Plant industry has on the environment, it is necessary to conduct detailed Environmental Impact Assessment studies by collecting the baseline data and identifying, predicting and evaluating the potential impacts based on which a. sound environmental management plan can be evolved. This will enable the project authorities to take necessary steps for safeguarding the environmental quality in the surrounding. In this paper an attempt has been made to highlight the important step of conducting Environmental Impact Assessment for a Water Resource Project.

Management of groundwater resource is determined by its accessibility and utility in terms of quantity and quality. The results of chemical analysis for pH, electrical conductivity (EC), total dissolved solids (TDS), total hardness (TH), total alkalinity (TA), calcium (Ca+2), magnesium (Mg2+), sodium (Na+), potassium (K+), chloride (Cl-), nitrate (NO3-), sulphate (SO4-) and fluoride (F-) of 18 water samples collected from Lalsot urban area in Dausa district are presented. Based on the results, certain parameters like sodium adsorption ratio (SAR) and percent sodium (% Na) were also calculated. Statistical analyses have been carried out using chemical data to classify geo-chemical evaluation of the aquifer system based on the ionic constituents. Salinity and nitrate contamination are the two major problems in the area, which is alarming considering the use of this water for drinking. The major factors influencing the water quality are local geo-chemical formation, water-rock interaction, flow direction of groundwater and rainfall that control the overall mineralization.

Iron is an essential trace metal, required as a constituent of oxygen carrying and oxidative-reductive micro-molecules such as haemoglobin, myoglobin and cytochrome. Amongst various components, iron is an important trace metal required for all biological systems. Owing to the universal presence of fluoride in earth's crust, all waters contain fluoride in varying concentrations. Fluoride is an element of high biological activity and has a tendency to accumulate in organisms, making detrimental effects in very low and high levels of exposure. Inorganic nitrogen may exist in the free state as nitrogen gas, or as nitrate, nitrite or ammonia. Nitrate represents the highest oxidized form of nitrogen. Many groundwaters have significant quantities of nitrates due to leaching of nitrate with the percolating water. Iron, fluoride and nitrate concentration along with temperature and colour, in the drinking water from some villages of Aundha taluka of Hingoli District were studied monthly during January to June 2005. The samples were analysed with standard methods and observed results were compared with prescribed limits set by WHO and ICMR.

Ecol Envir Conserv 2008, 14(4), 523-7.
The sewage irrigated soils of peri urban area nearby Vadodara city was surveyed to know the heavy metals contamination and nutrient status of sewage irrigated fields. The soils were found alkaline in reaction with build up of soil salinity besides increase in organic carbon, available P and K as well as micronutrients (Fe.Zn) over tube well irrigated soils of adjoining area. The contents of P, K,S, micronutrients as well as heavy metals were more concentrated in upper 30 cm depth in both the soils.Amongthe metals, DTPA-Fe (r = 0.657**), Cu (r = 0.637**) and Pb (r = 0.739*) showed positive correlation with organic carbon in sewage irrigated soil. The average available and total contents of heavy metals viz., Pb, Co and Ni were also higher in sewage irrigated soils than adjacent tube well irrigated soils. The findings of the present investigation emphasize the contamination of soils in pen urban areas especially with heavy metals viz., Pb, Ni and Co which are irrigated with sewage water over the years.

Phytoplankton composition and abundance variation at the Tarkwa-bay jetty was investigated for six months (July - December, 2004) in relation to environmental characteristics. Tidal sea water inflow and rain events were key factors governing the hydrology and water chemistry characteristics of the area. The phytoplankton species encountered were pointers to the water status which reflected its proximity to the sea and its influence. Four classes of phytoplankton were identified, the Bacillariophyta (48 taxa), Dinophyceae (4 taxa), Chlorophyceae (3 taxa) and Cy-anophyceae (2 taxa). Furthermore, the micro-flora recorded were chiefly neritic species. It is possible that the reduced species diversity recorded comparative to other similar studies in the region could be a reflection of the effect of stresses from habour related activities and refined oil discharges in the area. High tidal activities in the area may be helping to prevent the retention of waste ladenned water by eventual flow-dilution to the sea.

Investigates the changes in the levels of pH, moisture and organic matter contents of soil contaminated with crude oil for 105 days. The soil moisture content increased as the days of study increased and soil organic matter content decreased as the period of study increased. The effect of days of study on the pH diminished after day 63.A high positive correlation (p = 0.621) exists between the pH of the contaminated soil and the concentration of the crude oil added to the soil and the correlation between the pH of the contaminated soils and the days of sampling is low (p = 0.238). Although a high positive correlation (p = 0.767) exists between the concentration of crude oil added to the soil and the percentage organic matter content of the soil, a negative correlation (p = -0.237) exists between the percentage organic matter content of the soil and the days of sampling. The implication of the decrease on the organic matter content with the increase in the period of study is that the coagulation of the soil due to crude oil pollution reduces as the period of the exposure of soils to crude oil pollution increases. The low moisture levels of the polluted soil indicate that due to crude oil pollution less dissolved materials will be available for plant uptake and subsequent metabolism. The pH range observed in the study implies that crude oil pollutions makes the soil to acidic thereby increasing the toxicity of the soil. The increase in soil toxicity the less availability of materials like nutrients and the high coagulation of soil particles due to crude oil pollution are the major causes of poor growth of plants in crude oil polluted soil.

Dark colour, low pH and high organic load characterize the distillery waste called as spent wash. If spent wash is disposed off in environment without proper treatment it poses threat to it. Out of available treatment options aerobic composting of spent wash is one of the best options. The by-products of sugar industry such as press mud and bagasse were used as filler materials. The experiments were carried out in plastic containers of 20-L capacity. The press mud and bagasse were mixed in 5:1 proportion. The spent wash was added to this mixture till the moisture content was approximately 70%. The seeding was done with the help of Farm Yard Manure (FYM). The aeration was done manually by overturning the contents for 30 days at the interval of one day. The samples were analysed for temperature of composting mass, moisture content, organic carbon, nitrogen, pH, COD, chlorides and conductivity. Reloading of spent wash was done to maintain the moisture content. It was observed that the rate of reaction was higher at the initial stages of composting. The increase in temperature was observed at the initial stage, which went on decreasing as composting of the mass was completed.

In thermal power stations, surplus heat is produced as a result of energy production. About 15% surplus heat is discarded directly into the atmosphere through the flue gas. The reminder is rejected from the condenser through cooling water leading to physico-chemical and biological changes in the surrounding environment. The changes in temperature of receiving water bodies through surplus heat cause adverse impact, which changes the utility and productivity of organisms. The coal fired Thermal Power Station (TPS) releasing huge amounts of fly ash mixed with water into the aquatic environments. This may gradually lead to deterioration of such ecosystem. Discharges of oil from TPS also have adverse impact on aquatic ecosystem. The aim of present study is to discuss the effects of TPS on aquatic ecosystems.

The waters of Shivkhori stream, Raunra Tawi khad and Thanna Tawi khad stream of Kalakot area, Rajouri district, J&K state were subjected to analysis by Atomic Absorption Spectrophotometry for elements Si, Al, Fe, Ca, Mg, Na, K, Mn, Ni, Cu, Pb, Zn and Cr. All the elements except Si and Al were present within permissible limits in all the samples according to Bureau of Indian Standards and WHO. Aluminium is objectionable in four out of the 15 samples analysed, and silicon is present more than the permissible limits in all the samples. A good afforestation programme together with adopting Vetiver technology in the watershed areas of the region will screen out many of the elements including Al and Si not to enter the solution of the waters. Nitrates, sulphates, chlorides, bicarbonates, TDS and total hardness (TH) are all within the prescribed limits, and hence with respect to all these parameters, the waters are safe to be used for human consumption and also for agricultural use. SAR and SSP values of all the samples are within the prescribed limits, and hence the waters cannot be considered to create any harm as far as agricultural use is concerned. The waters of all the three streams are recommended to be subjected to chlorine/bromine disinfection to render the same safe for human consumption. Last, but not the least, attention needs to be paid towards bad sanitation prevailing near the banks of all the streams, which needs to be improved upon.

Acta Cienc Indica-Chem 2008, 34(1), 87-92.
India has many localized areas where water pollution creates situations not only hazardous to health but also injurious to the economy in several ways. In developed countries the waste water consisting of industrial effluents, domestic sewage, thermal and radioactive pollutants, sludges of municipal and other pollutants receives some sort of treatment before it get mixed in water bodies. If these urban sewage will be recycled and reused, it can generate cheaper fuel gas and electricity. Treatment of sewage yields irrigation water that contains all the essential nutrients such as nitrogen, phosphorus and potassium that makes it a good fertilizer. In the present paper, an attempt has been made to focus some light on the economic potentiality of the three sewer-nutrients flowing wastefully through drain water at two different sites of Jaunpur municipal area. The market values of their corresponding fertilizers have also been calculated to prove that the dirty water is economically a 'Black Diamond'.
