Abstract: Fluoride concentraion in Ground water in Narkatpally Mandal is a matter of a serious concern. The concentration is varying from 3.2 to 12.0 ppm. In all the places higher fluoride concentration is noticed, which is above the acceptable limits. More than 80% of the people living in the area are suffering from skeletal and dental fluorosis. Fluoride concentration is more in the deeper aquifers, can be overcome by bringing the water table to shallow levels.

Abstract: The present paper deals with the primary productivity of Kapla beel, a freshwater wetland located in the Barpeta district of Assam. The investigation was carried out during the period of 2003-2005, covering four seasons (Premonsoon, Monsoon, Postmonsoon and Winter) of a year. The analysis revealed Gross Primary Productivity (GPP) in the range of 137.29-697.80 mgc/m3/hr, Net Primary Productivity (NPP) 87.5 - 604.73 mgc/m3/hr, Community Respiration (CR) 48.59-174.78 mgc/m3/hr and GPP/NPP ratio 1.22-1.64. The study showed maximum GPP and NPP during winter season and minimum in monsoon season. The maximum and minimum GPP/NPP ratio was observed during monsoon and winter season respectively.

Abstract: In Madhya Pradesh the Betwa River flows near the Mandideep industrial area a little outside the capital city of Bhopal. The river also finds ample mention in the ancient epics like the Mahabharata. The Betwa River finds mention as the Shuktimati River in the mythological texts as the venerable river on whose banks the capital of the Chedi kingdom rested. Mandideep is an industrial area of Madhya Pradesh. Lot of industries are situated in the catchment area of Betwa river. The industrial effluents generated through these industries finds its way in the river, either through surface runoff or through drains joining to the river at different places. This industrial effluents leads to water quality deterioration. In the present study an attmept is made to assess water quality of Betwa River at a stretch of 5-6 kilometers. The parameters like turbidity, pH, Total hardness, dissolved Oxygen (DO), Biochemical Oxygen demand (BOD), Chemical Oxygen Demand (COD) and some heavy metals like Cr, Mn have been studied. Seasonally an increase in values of BOD, COD and Heavy metal was recorded during monsoon season which clearly indicates the pollution load through surface runoff or inflow through inlets.

Abstract: A case study was carried out by subjecting 25 agriculture wokers from a remote village of Mahaboobnagar district of Andhra Pradesh, India, occupationally exposed to an organophosphate pesticide. Malathion for clinical and cytogenetic analysis in order to see the potential clastogenic effect of the pesticide. Exposed and control groups were selected from the same geographical area. The mean age group of the workers calculated was 35 + 8.89 years and the mean duration of exposure to the pesticide was 6.5 years. Headache (62%), Giddiness (50%), ocular symptoms (30%) and parathesis (15%) were the commonest clinical symptoms recorded among the pesticide workers. The cytogenetic study reveals that the individual exposed to pesticides showed substantial clastogenic effect (CA ' s, 2.62 + 0.22) compared to controls (0.52 + 0.10, P<0.001).

Keywords: Biosurfactant, Naphthalene, Bioremediation, Ochrobactrum anthropi, Glycolipid
Abstract: The biosurfactant reported in this study was extracted from the culture supernatant of novel Ochrobactrum anthropi grown in mineral salt medium containing glucose and hexadecane. The potential of the biosurfactant to enhance bioavailability and the degradation of naphthalene was investigated. The biosurfactant was found to be glycolipid with a critical micelle concentration (CMC) value of 0.04%. Biosurfactant enhanced the dissolved concentration of naphthalene to above 500 mg/L, which is 16 times higher than the saturated solubility of naphthalene under standard condition. Varying the pH and NaCl concentrations did not affect the solubilization of naphthalene by the biosurfactant. Solubilized naphthalene is biosurfactant solutions was biodegraded by the same microorganism that produced the biosurfactant. The presence of biosurfactant doubled the rate of naphthalene degradation by Ochrobactrum anthropi whereas Sodium dodecyl sulfate (SDS), anionic surfactant inhibited the growth and thus biodegradation of naphthalene at the conditions studied. The enhanced degradation of naphthalene by Ochrobactrum anthropi in presence of biosurfactant indicates its potential for bioremediation of sites contaminated with hydrocarbons having limited water solubility.

Abstract: A study of the groundwater of Patna town in Bihar was carried out to examine its suitability for drinking purpose. Groundwater forms the major source of drinking water supply in the municipal area of Patna town. For the analysis of groundwater, eighty-four water samples were collected from the tap water system located in different areas of the town. The data were analyzed with reference to BIS and WHO standards and it was found that the physico-chemical parameters are well within the maximum permissible limit of drinking water standards. However, low fluoride content (mean 0.6 mg/L) is observed in all groundwater samples and high iron content (mean 0.45 mg/L) in 13% of the samples. The study also revealed that groundwater of area is very hard and is dominated by carbonate and bicarbonate anion with calcium and magnesium cations.

Abstract: Seafood is the major source of food of large number of people of the coastal area of Maharashtra. Six species of fish samples namely Coilia dussumieri, Harpodon nehereus, Dasyatis sephen, Restrelliger kanagurta, Cyanoglosus semifasciatus and Sepia afficinalis (Cuttle fish) were collected directly from the sea of the Goraie beach of Mumbai by catch from a distance of 200 meters away from the coast. These samples were brought to the laboratory and dried. The dried fishes were crushed into a fine powder by mortal and pestle and stored in amber colored bottles in vacuum desiccators. These samples were evaluated by Atomic Absorption spectrophotometer for the determination of the five heavy metals namely arsenic, cadmium, mercury, lead and zinc. The highest concentration of Hg was recorded in all the species of fishes analyzed (46.58 ppm to 67.62 ppm). However, the fish tissues did not show any detectable amount of arsenic. The concentration of lead was found between 0.83 ppm to 3.13 ppm, and zinc was also found between 0.95 to 1637.29 ppm. The concentraion of cadmium was found in between 0.42 to 24.11 ppm in Goilia dussumieri, Dasyatis sephen, Gyanoglosus semifasciatus and Sepia afficinalis (Guttie fish) while in others the cadmium was not detected. These results reveal that the contamination of Hg in the fishes studied is above the tolerance limit. However no evidence for Hg pollution in coastal area is reported. This may be due to the fact that fish is consumed after frying it whereby Hg gets volatilized.

Abstract: Hydrogeochemical studies have been carried on representative 10 groundwater samples collected nom dug-cum-borewells in Chityal area, Andhra Pradesh to understand the major ion and fluoride distribution. Parameters such as electrical conductivity, pH, TDS and major ion concentrations such as Ca+2, Mg+2, Na+, K+, CO3-2, HCO3-, Cl- and F- of groundwater were determined. Granite Gneiss and dykes of Archaean era are main lithological formations. The analytical results indicated that Groundwater is acidic to alkaline and mostly bard in nature. Possible sources of fluoride are weathering and leaching of fluoride bearing minerals. High rates of evapotranspiration intensive and long term inigation are the supplementary fudors to further increase of fluoride content in groundwater.

Abstract: Reservoirs and lakes with clear cut boundaries represent one of the most versatile ecosystems on the surface of the earth. Like any other systems, reservoirs are characterized by inputs and outputs of materials and hence represent an ongoing chemical process. The sediments that are carried to the reservoirs by catchment erosion, get progressively sedimented to the bottom and the rapid interaction of sediment and water aided by biological activities makes reservoir an interesting laboratory. In this study, an attempt has been made to evaluate the suitability of reservoir water for drinking and irrigation by taking two reservoirs, viz., Malampuzha and Pothundi, located towards the north and south respectively of ' Palakkad Gap ' - a prominent structural discontinuity in the Western Ghats of Kerala
