Abstract: Tapti pond of Multai is one of the importatn sources of water supply to agricultural areas which receives domestic waste water almost throughout the year and exhibits abundance of phytoplankton population. Year long study was conducted to measure various physico-chemical parameters; the turbidity of pond water was found to be highest during June-July and low in the month of November. BOD was high in the month of July while low in December. The study revealed that there is greater degree of pollution in the studied pond and hence, preventive measures are required to avoid further deterioration of the pond water quality. The Estimated water quality parameter was compared with the WHO standards.

Abstract: The present study was conducted in freshwater lake, Powai Lake, Mumbai. Concentrations of nutrients namely nitrites, nitrates, phosphates and silicates were recorded. The mean nitrite nitrogen concentration was found to be 0.0289 (+ 0.0121) mg/L. The mean Nitrate nitrogen concentration was recorded as 0.344 (+ 0.098) mg/L. Total nitrogen was observed to be 0.373 (+ 0.108) mg/L. Mean phosphate concentration was found to be 0.407 (+ 0.105) mg/L. Mean silicate value was found out to be 25.97 (+ 2.17) mg/L. N:P was found to be 0.915 (+ 0.120) mg/L in the entire study period. The nutrient levels indicate that the lake is eutrophic. Various trophic algal indices namely (i) the myxophycean index; (ii) the chlorophycean index; (iii) the diatom index; (iv)euglenophyte index and (v) the compound index and algal species diversity indices like (i)Shannon-Weiner index and (ii) Simpson index were calculated. The myxophycean index was found to be 3; the chlorophycean was observed to be 2; the diatom index was found to be 0.25 whiel the euglenophyte index was 0.2 and the compound index was found to be 3.5. Shannon-Weiner Index was found to be 3.348 (+ 0.0126) and Simpson diversity index was observed to be 0.877 (+ 0.00717). The results show that the lake is eutriphic.

Abstract: The present study was conducted in an urban lake, Powai Lake, Mumbai. Concentrations of nutrients namely nitrites, nitrates, phosphates and silicates were recorded. The mean nitrite nitrogen concentration was found to be 0.0289 (+ 0.0121) mg/L. The mean Nitrate nitrogen concentration was recorded as 0.344 (+ 0.098) mg/L. Total nitrogen was observed to be 0.373 (+ 0.108) mg/L. Mean phosphate concentrations was found to be 0.407 (+ 0.105) mg/L. Mean silicate value was found out to be 25.97 (+ 2.17) mg/L. N:P was found to be 0.915 (+ 0.120) mg/L in the entire study period. The nutrient levels indicate that the lake is eutrophic. With reference to the zooplankton, a total of 13 species belonging to Copepoda, Cladocera and Rotifera groups were recorded. Copepods are observed to contribute on an average 42.43 (+ 1.30)% to the total zooplankton. Cladocera was the second most abundant group in zooplankton with a contribution 34.3 (+ 0.67)%. Rotifera was the third most abundant group among zooplankton and their contribution to the total zooplankton was 21.1 (+ 0.7)%. Pearson Coefficient of Correlation has been worked out for nutrient concentrations and zooplankton populations. The results reveal that there is strong correlation exist between nutrient concentrations and phytoplankton population in an urban eutrophic lake.

Title: Removal of copper and nickel from aqueous solutions using natural adsorbents

Subject: Pollution Research
Keywords: Adsorbents, biosorption, heavy metals, Phyllanthus emblica, Gmelina arborea
Abstract: A major cause for the presence of copper and nickel in aquatic systems is the leaching of chemicals and pesticides from agricultural lands to the nearby water bodies. Gradually these metal ions pollute drinking water sources and thus many of the water sources contain metal ions beyond the permissible limits. The removal of heavy metal ions from water sources by cost effective methods are gaining more important. Recently new technologies have been developed for the removal of heavy metal ions from contaminated water samples. Biosorption is one such technology that can be very effectively used for the removal of metal ions from water samples. The aim of the present study is the removal of copper and nickel from water samples by low-cost and abundant, plant materials as adsorbents. Charcoal prepared from the bark of Phyllanthus emblica and the seed pods of Gmelina arborea are the adsorbents used for the investigation. The adsorption efficiency, effect of pH, the adsorbent dosage and the contact time were studied. The experiments were conducted at room temperature and the adsorption efficiency of the materials used was found to be promising. The adsorption was found to be pH dependetn in the removal of copper and nickel from water samples. The best results were obtained in the pH range 4.00-5.00. A definite amount (500 mg) of the adsorbents had an uptake of 55 to 60 mg of the metal ions from 0.025 molar metal ion solutions.

Keywords: Methyl blue, methylene blue, adsorption, Sugarcane bagasse
Abstract: Synthetic dyes are used extensively in the textile industry for dyeing nylon, wool, cotton, and sil, as well as for colouring oil, fats, waxes, varnish and plastics. The wastewater containing dyes emanating from textile mills are strongly coloured and are carcinogenic in nature. In order to reduce pollution load, it is desirable to decolorize the water and remove the organic constituents before its discharge into the main stream. In present study adsorption behaviour of Sugar cane bagasse for removal of Methylene blue and Methyl blue has been investigated in a batch reactor. Adsorption experiments were carried out using 100 ml of dye solution (50 ppm) and adsorbent dose (0.5-2.0g) at 150 rpm at 250C. Rate of decolorization was estimated from residual concentration spectrophotometrically. The experimental results indicated that sugarcane bagasse can effectively remove 80-95% of the cationic and anionic dyes. The high decolorizing efficiency was obtained with 2.0 g/l of adsorbent dose. The experimental results were subjected to Freundlich isotherm.
