Abstract: Sesarma edwardsi, a crustacean species of Ganga estuary appeared in greater number in station-IV (minimum effluent linked site) and in very thin number in station I (effluent loaded site). The species showed population fluctation along with the variation of salinity and oxygen availability of the medium. The crustacean showed abundance during pre-monsoon period when dissolved oxygen content of the medium was higher. Presence of metals in the tissue of ' crustacean demotes their efficiency in the accumulation of metal contaminants which in other way suggests that the organism is a bioindicator of metal pollution.

Abstract: Removal of Arsenic (As-III) and Chromium (Cr-VI) from their aqueous solutions of different concentrations has been achieved in the present investigation by using carbonized organic waste material. Agro-based paddy stem and cow dung were used as adsorbents and compared with activated charcoal to determine the most efficient absorbent. The results reveal that highest removal efficiency for Chromium (IV) was with paddy stem absorbent (97%) at their 0.5 mg/L solution with 40 gm/L absorbent dose at pH 2.0 and 4 hr retention time. In case of Arsenic (III), 88.3% removal efficiency was observed with 0.5 mg/L solution at pH 7.0 and 4 hr retention time at same absorbent dose.

Abstract: Early growth period such as germination, emergence of radicle and shoot elongation is more sensitive to heavy metal pollution. The present study was performed to find out the toxic effect of nickel (0.5-5.0 m M) on the five locally grown cultivars of Indian mustard (Brassica juncia L) viz Pusa Jai Kisan, Pusa Bold, Gangotri, PT-1001 and Kranti. Indian mustard is very fast growing oil crop with a high biomass and commonly using for phytoremediation of heavy metals (Ni, Cd, Zn, As, Pb). The parameters like germination percentage, root and shoot growth, fresh and dry weight, moisture content, metal tolerance index and percentage phytotoxicity were studied which suggested the relative degree of toxicity of nickel on the deferent selected cultivars of mustard. Increase in Ni concentration in culture medium led to inhibition in germination and other growth parameters were detected. It was noticed that different selected cultivars for study, showed different degree of tolerance. From the observations it was concluded that Pusa Jai Kisan showed more tolerance towards nickel where as PT-1001 was found most sensitive to nickel toxicity. Conclusively the nickel tolerance by mustard cultivars were detected in the order of : Pusa Jai Kisan > Pusa Bold> Gangotri> Kranti > PT - 1001

Abstract: Evaluation of physico-chemical parameter of water samples from river Meenachil were carried out for one year. The statistical parameters such as Mean, Mean deviation, Variance, Standard deviation (SD), and Coefficient of variation (CV) were calculated. In order to assess the quality of water, the parameters were compared with their standard desirable limits for drinking water as prescribed by differetn agencies and sources such as WHO and BIS. The correlation coefficient ' r ' amongst the parameters was calculated and correlations between various parameters were worked out. Correlation analysis was done in order to assess the relationship between independent and dependent variables. Significant positive and negative correlations among the parameters were determined. The correlations found significant at 5%, 1% or 0.1% levels were used for assessing water quality (Tiwari et al. 1986)

Keywords: Clarias batrachus, lipid, Copper sulphate
Abstract: The present study reflects the effect of copper sulphate on the lipid in some vital organs of Clarias batrachus. The acclimated fish of equal size were treated with different concentrations of copper sulphate (0.5, 1.0, 1.5, 2.0 and 2.5 ppm) respectively. The morality rate was noted up to 96 hours. After finding LC50 , the fish were treated with a sub lethal concentration of copper sulphate (1.5 ppm) for 24, 48, 72 and 96 hours respectively. The total lipid estimation was done in stress of sub lethal concentration (1.5 ppm) of copper sulphate and compared with the control group of fish. The results showed a significant decline in the total lipid in various organs of Clarias batrachus at sub lethal concentration of copper sulphate viz., brain (78.2%) < kidney (63.79%) < gonad (63.33%) <liver (55.8%) < muscle (27.16%). While increased in the lipid in various organs of controlled fish viz., muscle (0.081 mg/100 mg) > kidney (0.058 mg/100m) > brain (0.046mg/100mg) > gonad (0.045 mg/100m) >liver (0.034 mg/100mg). The lipid reduction in the present study is reflection of breakdown of lipid in stress.

Abstract: Group A streptococcal infections and the suppurative as well as non-suppurative sequelae account for one of the most important and major health problems in India. The ? - haemolytic Streptococcus pyogenes is one of the commonest bacterial pathogens that cause acute pharyngitis in pediatric age groups living in lower socioeconomic conditions. Increased occurrence of streptococcal sore throat was found in late summer and rainy season. Males were more prone to this infection as compared to their female counterpart. The high asymptomatic carriage rates of the organism increase the risk of spreading the infections in a particular geographic. The present study was aimed for determination of prevalence of throat carriage rates of group A ? - hemolytic streptococci in both the healthy (asymptomatic) and diseased (symptomatic) individuals of both sexes of pediatric age group.

Abstract: The lakes of the silicon city of Karnataka are man-built generally for hydrological reasons. The ecological roles played by lakes are very vital, in providing drinking water, irrigating agricultural fields, fishing, washing, brick making, and supporting a variety of birds, growth of many types of vegetation, and other habitats. The impact of water bodies on the city climate is also significant: manmade landscape was beautiful once upon a time, but now these lakes ae polluted by domestic waste combined with sewage and causes organic pollution because of higher concentration of nitrates and phosphates, which encourages the growth of obnoxious weeds, such as water hyacinths. These floating weeds prevent the penetration of sunlight, which is essential for all life forms, and adversely affect aquatic life and upset the delicate equilibrium of the wetland ecosystem, and these industrial effluents to lakes pollute and contaminate water, which in turn percolate to aquifers and affect groundwater sources. To conserve these valuable resources from further deterioration, there is a need for regular monitoring of the aquatic ecosystem.
