Novel adsorbent was prepared from waste sludge obtained from a sugar mill for removing heavy metals from industrial wastewater. The adsorption studies were carried out in batch and continuous modes for both sugar mill sludge based carbon and commercial carbon. In batch studies, experiments were conducted at ambient temperature to assess the influence of the parameters such as pH, adsorbent dose, contact time and equilibrium concentration. Adsorption data for the prepared carbon was found to satisfy both the Freundlich and Langmuir isotherms. Column studies were carried out to delineate the effect of varying depth of carbon at constant flow rate. The breakthrough curves were drawn to establish the mechanism. The result shows that the sludge based activated carbon can be used as an alternative for commercial carbon.

Pea (Pisum sativum Linn.) plants were raised in post irrigated soils with graded nickel, rated for various levels of available (DTPA extractable) Ni viz. 0.12 (control), 0.52, 1.92 and 2.86 ppm in soil. The effect of these soils on growth (length, fresh and dry weight), visible toxicity and biochemical responses (protein, chlorophyll and sugar contents and catalase activity) of pea were evaluated. Plants grown at highly Ni-contaminated soil (available 2.86 ppm Ni) had visible symptoms of toxicity in the form of stunted growth (observed at 20 days after sowing). The toxicity symptoms were less severe and appeared 35 days after sowing at 1.95 ppm available Ni in soil. Fresh and dry weight of pea increased by 105 and 91%, respectively at 1.95 ppm Ni. Chlorophylls (a, b and total) and sugar contents were stimulated up to 0.52 ppm available Ni. Maximum increase in protein content was found at 1.95 ppm Ni. Catalase activity increased with increase in available Ni concentrations in soil from 0.12 to 2.86 ppm. Antioxidative defence systems with respect to protein content and catalase activity favored the biomass production in pea at high concentration of Ni (above 0.52 ppm), whereas sugar and pigment contents declined above this concentration. Pea plants tolerated low Ni (available 0.52 ppm) concentration. High concentrations (available 1.95 and 2.86 ppm) were not stimulatory to growth and produced visible toxicity.

Attempt is made to formulate multiple regression equations using all possible regressions method for groundwater quality assessment of Ajmer-Pushkar railway line region in pre-and post-monsoon seasons. Correlation studies revealed the existence of linear relationships (r≥0.7) for electrical conductivity (EC), total hardness (TH) and total dissolved solids (TDS) with other water quality parameters. The highest correlation was found between EC and TDS (r = 0.973). EC showed highly significant positive correlation with Na, K, Cl, TDS and total solids (TS). TH showed highest correlation with Ca and Mg. TDS showed significant correlation with Na, K, SO4, PO4 and Cl. The study indicated that most of the contamination present was water soluble or ionic in nature. Mg was present as MgCl2; K mainly as KCl and K2SO4, and Na was present as the salts of Cl, SO4 and PO4. On the other hand, F and NO3 showed no significant correlations. The r2 values and F values (at 95% confidence limit, α=0.05) for the modelled equations indicated high degree of linearity among independent and dependent variables. Also the error % between calculated and experimental values was contained with ±15% limit.

Anasagar is a perennial, shallow fresh water body which is degraded because of agricultural and other anthropogenic activities, such as input of detergent, sewage disposal, human settlement around the lake etc. In the lake waters as well as in the catchment area, pesticides are being used by the farmers which lead to contamination of water. Gas chromatographic analysis of 120 contaminated water samples collected from the lake was carried out. The organochlorine pesticides recorded in the samples were Heptachlor, β-HCH, γ-HCH, Aldrin, DDT and Endosulfan. The average ranges of these pesticides were 0.0224ppm, 0.1035 ppm, 0.0478 ppm, 0.0041 ppm, 0.1381 ppm and 0.5051 ppm, respectively. The study revealed that water of Anasagar is highly contaminated with these synthetic pesticides. Among these agrochemicals, the level of Endosulfan, DDT and γ-HCH were found to be significantly high in the lake. Therefore, the research efforts are needed to conserve the wetland as well as to minimise the impacts of agrochemicals on the lake ecosystem.

J envir Sci Engng 2010, 52(1), 1-6.
One of the main toxic pollutants in drinking water is heavy metals which must be reduced to standard levels. Removal of trace amounts of heavy metals can be achieved by means of membrane processes such as nanofiltration. Removal efficiency of a nanofiltration membrane is strongly affected by operating conditions. Focusses on the effect of two key parameters, i.e. transmembrane pressure and feed concentration on the removal of heavy metals (arsenic, chromium and cadmium) from water by a polymeric nanofiltration membrane UTC-70UB charged negatively. The rejection experiments included variation of heavy metals feed concentrations in the range of 100 to 400 μg/L for arsenic and chromium and 20 to 80 μg/L for cadmium, and different transmembrane pressures in the range of 5 to 14 bar. The results indicated that under most conditions tested in this research, the rejection of heavy metals was found to increase when the transmembrane pressure was increased. The results also showed the high rejection percentage of the heavy metals, with the maximum retention values of arsenic, cadmium and chromium, 97%, 100% and 95% respectively. The percent reduction of arsenic and chromium was found to enhance as their concentration in the feed increased. However, in the case of cadmium, the rejection was reduced with increase in the concentration.

A carbonaceous adsorbent prepared from an indigenous waste by acid treatment was tested for its efficiency in removing Rhodamine B (RDB). The parameters studied include agitation time, initial dye concentration, carbon dose, pH and temperature. The adsorption followed first order reaction equation and the rate is mainly controlled by intra-particle diffusion. Freundlich and Langmuir isotherm models were applied to the equilibrium data. The adsorption capacity (Qm) obtained from the Langmuir isotherm plots were 84.842, 88.574, 92.425 and 96.284 mg/g respectively at an initial pH of 7.0 at 30, 40, 50 and 60°C. The temperature variation study showed that the Rhodamine B adsorption is endothermic and spontaneous with increased randomness at the solid solution interface. Significant effect on adsorption was observed on varying the pH of the Rhodamine B solutions. Almost 83% removal of Rhodamine B was observed at 60°C. The Langmuir and Freundlich isotherms obtained, positive AH° value, pH dependent results and desorption of dye in mineral acid suggest that the adsorption of Rhodamine B on FBC involves physisorption mechanism.

The quality of air with respect to SPM, S02 and N02 has been also assessed on respective sites to see its effect on biochemical parameters of the leaves i. e. pH, total water content, chlorophyll and ascorbic acid and evaluate the (air pollution tolerance index(APTI) of various plants. It was concluded that Pongamia pinnata 15.8, Pithecolobium dulcis 34.8, Holoptelea integrifolia 55.8 and Saraca indica 52.0 have very highAPTI value over control so these are considered as high tolerant tree species, Ficus rumphii 35.7, Azadirachta indica 30.5 and Grewelia robusta 34.3 have slightly more APTI value over control so these are considered as moderately tolerant tree species and Alstonia scholaris 21.5,Cassia simea 6.09 and Bauhinia variegata 18.22 have less APTI value than control, so these are sensitive species respectively. One way ANOVA finds the obtained values to be highly significant (≤ 0.001) at the industrial site. Thus present findings show that Brass and allied industries are the prominent sources responsible for the elevated level of air pollutants at the industrial site.

Asian J expl Sci 2010, 24(1), 175-8.
Many of petroleum compounds either immediately or ultimately come in contact with the environment or are sequestered by soil. These are priority organic pollutants of critical environmental and public concern. With the multiplying population and progress of urban civilization, pollution caused by petroleum products and their wastes is increasing in logarithmic manner. Bioremediation of these contaminants is a prerequisite of today's world. Many parameters play an important role in microbial degradation. Physico-chemical analysis of contaminated soil was carried out using different methods. Physical analyses like soil texture, soil pH, bulk density, C/N ratio, soil moisture content, organic matter, presence of heavy metal etc. were performed. All of these parameters play an important role in biodegradation of petroleum compounds. Chemical analysis of soil was also performed using GC-MS. Presence of heavy metal ions was estimated by using atomic absorption spectroscopy (AAS). Excess hydrocarbons adversely altered the properties of the contaminated soils. Low water holding capacity and porosity and very high C:N ratio and bulk density were observed in every contaminated sample of soil. High concentration of many heavy metals was also seen.

In the current study an approximation of the quality and quantity of the generated waste in food industry of Guilan province, which is recognized as the largest waste generator industry in the study area in Iran is provided. In present study, questionnaires were used to collect data regarding methods of waste management used in 142 of the food businesses in the area of study. The results of the present research show that putrescibles are the most important waste in this industry. The high percentage of putrescibles in the waste stream (73.7%) and relatively appropriate physico-chemical characteristics of the waste, suggest the possibility of composting. Additionally, more than 70% of total non-organic wastes is contributed to packaging processes. There are relatively few industries that implement such correct waste management. Relatively low price of raw materials and lack of efficient penalties in case of inappropriate waste disposal by industries are considered as the major reasons of such deficiency in regional waste management. It is highly recommended that the implementation of such tax policy accompanied by joint management of generated industrial wastes be enforced in the area.

Water pollution by toxic heavy metals is a burning environmental problem and has presented a challenge to humans. Removal of heavy metals using non-living biomass of fungi could be a potential solution to this problem. This study evaluated the potential of fungal and rice straw biomass to remove copper and cadmium from aqueous solution. Pretreated fungal biomass by autoclaving showed the uptake percentage 65% and 77% of copper and cadmium respectively at 30 min. of contact time. Maximum uptake percentage 79% and 82% of copper and cadmium respectively at 30 min. of contact time was obtained by pretreated fungal biomass by 0.04N NaOH. On the other hand, the pretreated of fungal biomass by 0. IN NaOH decreased the uptake percentage of copper and cadmium. The uptake percentage of copper and cadmium by rice straw was not differed but the pretreated of rice straw biomass by NaOH increased the uptake percentage of copper and cadmium.. The fungal biomass was found to be effective in removing considerable amounts of copper and cadmium from aqueous solution compared with rice straw biomass. Thus, fungal biomass could be important in the removal of heavy metals

J envir Biol 2009, 30(4), 615-19.
This study focused on the evaluation of the specific biological heat potential (h) of a food-processing artificial wastewater in the autothermal thermophilic aerobic treatment (ATAT) system. A novel experimental method was developed to evaluate the hb value by using the heat balance model under the steady state. This system was daily fed with oily and artificial wastewater at 21460 mg/1 COD. The sludge retention time (SRT) was controlled at 15 days. The results showed that the average values of hb were 3.25 to 3.63 kcal g1 COD-removed for the artificial wastewater. The values of true growth yield (Y) were 0.08 to 0.19 mg-MLSS mg1 COD for the food-processing wastewater at different temperatures. The COD removal efficiency was 77 to 91 %, and it was decreased as temperature increased. But, the oil and grease (0 and G) removal efficiency was 50 to 69%, and increased as temperature increased. These results might indicate that oil and grease become more soluble and accessible to microorganisms at high temperatures. The study indicated the temperature effect constant (0) of van't Hoff-Arrhenius law was 0.958, which explained and showed typical characteristics in the low sludge yield of an ATA T process.

Concept of carbon credit came into existence as a result of increasing awareness of the need for controlIing emissions. Carbon credits are a key component of national and international emissions trading schemes that have been implemented to mitigate global warming. Today developing countries are getting additional revenue for their various projects which result in reduction of Green House Gas emissions. This has become possible through Kyoto Protocol of United Nations Framework Conventions on Climate Change (UNFCCC) came into force with effect from 16th Feb. 2005 and is now fully operational through Clean Development Mechanism (CDM). India's economic growth is mainly based on energy from fossil fuel & therefore has considerable potential in reducing its Green House Gas emissions as well as in CDM participation. There is a need of more and more awareness in our country regarding CDM project so as to avail maximum benefits for our various projects to be covered under runner CDM category of UNFCCC. An attempt has been made to discuss an overview of green house effect,.Kyoto protocol and emerging green house gas market, its concept to understand the CDM project.

Wheat (Triticum aestivum L cv. Sonalika) seedlings were grown in presence of K2Cr2 O2 (10,50 and 100 ppm) for 7 days and growth, total chlorophyll, activities of antioxidative enzymes like superoxide dismutase (SOD; EC 1.15.1.1), catalase (CAT; EC 1.11.1.6) and guaiacol peroxidase (POX; EC 1.11.1.7) and lipid peroxidation were determined in mot and shoot tissues. Growth of the seedlings was significantly (p ≤ 0.05) depressed and at 100 ppm, root length was reduced by 63% and shoot length by 44% in comparison to the respective controls. Total chlorophyll loss in shoots was about 46% at 10 ppm ofK2Cr207 which further increased to 80% at 100 ppm. Both in root and shoot tissues, activities of SOD and CAT declined with increase of metal in growth medium and it was significant (≤ 0.05) even at lowest concentration of the metal tested. But POX activity showed a different trend. In root tissues it was decreased whereas in shoots, there was many fold increase in the activity (about 370% over control at 100 ppm). Malondialdehyde (MDA) content increased both in root and shoot tissues, but it reached significant (≤ 0.05) level at 50 ppm in roots and at 100 ppm in shoot tissues. Even though antioxidative enzyme activities were not assayed in germinating embryos, inhibition in germination percentage (by 40% at WOppm) and increase in lipid peroxidation level (by 71% over control at 100 ppm) were observed in 2-day-old embryos, germinated in presence of K2Cr207 (10, 50 and 100 ppm). The results indicated the imposition ofoxidative stress situations both during germination and early stages of seedling growth by Cr6 stress, which might be one of the probable reasons behind Crtoxicity in plants.

Explores the factors determining water consumption and conservation behavior (sources and uses of water) of the people for household purposes in the two regions. Second, it seeks to address a comparative assessment of health effects of drinking r water consumption in two regions. Also brings out the differences in the two regions in both life chances and levels of awareness. It can also be inferred that the nature of risk too determines the beliefs and consumption patterns which in turn ascertain the demand for infrastructure. Undoubtedly, the state support is required for building the infrastructure to solve water problem and the top-down approach of the government should be replaced by bottom-up model. The study suggests that the governmental and non-governmental actors have different roles to play for the different social practices, their role being dependent on the historical process and the tasks at hand.

J envir Biol 2009, 30(5; Suppl), 877-82.
Effects of three ions, Mn2+, Cu2+ and Zn2+ on biological treatment of pharmaceutical wastewater by a functional strain Xhhh were investigated. Through orthogonal tests, Cu2+ was determined to be the most important factor influencing Xhhh biodegradation performance. Biodegradation kinetic experiments demonstrated that with Cu2+ concentration at about 2.00 mg l-1, the maximum of specific growth rate and specific degradation rate were obtained tobe 0.033 and 0.0 75 d2+, respectively. The optimal levels of Mn2+ (5.00 mg l-1), Cu2+ (2.00 mg l-1) and Zn2+ (5.00 mgl-1) were achieved based on experimental results of their effects on the activities of manganese peroxidase and lignin peroxidase, and biodegradation kinetic parameters. Among three types of biodegradation kinetic models (Monod, Tessierand Contois), Tessier model was found most reasonable for kinetics description of Xhhh growth (R2 = 0.995) and pollutants degradation (R2 = 0.970) in the case of metals optimization. Both kinetics evaluation and experimental results demonstrated that optimization with the three metals made a great contribution to Xhhh growth and COD removal for pharmaceutical wastewater treatment.

Pseudomonas fluorescens strains were isolated from textile dye effluent contaminated soil samples collected from different parts of Tirupur town in Coimbatore district of Tamil Nadu, India. The ability of these strains to decolourise Congo red was studied in detail. The decolourisation parameters viz., dye concentration, temperature, pH and incubation time was optimised. Presence of plasmid was confirmed by obtaining plasmid profile on agarose gel electrophoresis. Plasmid curing was carried out using sodium dodecyl sulphate (SDS) and elevated temperature. The lose of plasmid was confirmed by antibiotic sensitivity tests. The optimal dye concentration, temperature, pH and incubation time for decolourisation of Congo red by uncured strains were found to be 0.7-1.75 mg/50 ml, 40°C, 7.0 and 3 days respectively. The effect of plasmid curing on decolourisation of Congo red was also analysed. The results indicated the involvement of plasmid in decolourisation activity.

Air pollution is a serious problem in urban areas of India and other developing countries. The number of automobiles has increased to N-fold due to rise in population and improved standard of living. The exhaust from the automobiles is one of the main causes for air pollution in the urban areas. Hence, it is the important area to be monitored continuously to improve the air quality in metro and urban areas. Ban of usage of automobiles with more than 15 years age, insisting Bharat III Standards for new vehicles and making periodical pollution check ups mandatory are few steps taken by the government. Government also has employed a team has to verify all pollution level verification certificates regularly. Physical verification of all such certificates is not only tedious, but also incomplete. As the automobile has to be taken to pollution check centre for pollutant level verification regularly, there is a possibility of human negligence. In the study, an attempt is made to use MOX sensors, cellular phone network, and micro-controllers to develop a new system, such that exhaust gas monitoring for automobiles can become automatic and simple.

J envir Biol 2009, 30(5; Suppl), 801-6.
In this study, variations in total dissolved phosphorus (TDP), soluble reactive phosphorus (SRP) and total iron (TFe) concentrations and pH values in the littoral sediment porewater of macrophyte-dominated eutrophic Mogan Lake (Turkey), were determined depth wise (0-20 cm, on a basis of 5 cm depths) over a period of eleven months. Additionally, water temperature, dissolved oxygen, redox potential, TDP, SRP and TFe levels in the overlying water were measured. Especially in the spring and summer months constituting a large portion of the research period, seasonal variation of SRP at depths between 0-5 cm and 15-20 cm were not found to be statistically significant (p>0.01). However, in the fall and winter months, surface sediment (0-5 cm) SRP values were elevated in comparison with deeper sediment depths. As for TFe values, no clear seasonal variation was evident at different depths. Due to the fact that TFe concentrations in the overlying water (101.25-511.67 mg.m3) were lower than iron concentrations in the porewater (104,00-783.00 mg.m-3), positive phosphorus release remained at low levels. In this eutrophic lake, in which action is continuing to reduce the external phosphorus load, monitoring SRP variations in the overlying water and porewater would be beneficial.

J envir Biol 2009, 30(5; Suppl), 841-6.
The soil C, N, P and K content of agricultural soil were measured over the last 4 decades in NE Catalonia (NE Spain). Plant-available P and K increased by ca 109 and 105% respectively and total N decreased by 30%. The increases in plant-available P content are in accordance with the increasingly used pig slurry being very rich in P,and with P tendency to be retained in soils, since it is less mobile than N. The total soil N (NM) decrease occurred in the first decade (by 41%). The uptake and withdrawal of mineral N by crops and the leaching of mineral N into groundwater and rivers after torrential rainfalls were the two likely major pathways ofN-loss from the soil. After the first decade, there has been no further decrease of Ntot as a result of the increasing fertilization of these fields, including the increasing applications of pig slurry. These results show an increasing P eutrophication in Mediterranean agricultural soils and will have several consequences for the next decades with (i) an increasing unbalance between N and P (and K) in soils that might affect crop productivity, (ii) an increasing leaching of N as nitrate to continental waters, both ground and surface waters, and (iii) a consequent need for the establishment of another fertilization strategy based on lowering the use of pig slurry and on increasing the use of fertilizers of slow mineralization that increase soil organic matter, and stabilise the soil N and P contents.

An attempt was made to find out the impact of shrimp farm discharges on benthic diversity in the discharge point of a shrimp farm. The duration of the study was one culture period right from stocking to harvest. The results revealed that the values of environmental entities were in the safe levels. As regards nutrients, maximum value of TOO and phosphorus were recorded in the sample collected after harvest and minimum in the sample collected during culture. BIO-ENV method revealed that nitrogen, sediment salinity and TOO were manifested as best variable combination explaining faunal distribution. Polychaetes are the dominant group (50%) with 13 species followed by crustaceans (32%) with 10 species, gastropods (10%) with 2 species and bivalves (8%) with 3 species. The faunal density was found to vary in relation to months as observed in the samples which were collected during various seasons in the other areas of estuary. In line with this, diversity values were also paralleled to the faunal density. In a nut shell, the study revealed no negative impact of shrimp farming to the estuarine benthic biota.

Bionano Front 2010, 3(1), 83-7.
Freshwater bodies are being polluted by a multitude of pollutants from various sources like, industrial effluents, municipal wastes, garbage's, sewage pollutants and agricultural wastes etc. these pollutants contain heavy metals, persistent chemicals and pesticides are carried through food chain, their concentration increasing at each link present a threat to man when we consume the hydrobioants from polluted water. Due to such mixing of pollutants coastal and inland water resources, global fisheries is facing constant decline in prawn stocks. In the present study, to find out the impact of Paravanar river pollutants on freshwater prawn, Macrobrachium malcolmsonii collected from three Stations viz., Station-I, Station-ll and Station-Ill such as, Unpolluted (Station-l), Less polluted (Station-ll) and More polluted (Station-Ill) regions. Lipid level changes were analyzed in various organs like, gills, testis, vasdeferens, hepatopancreas, and androgenic gland. Lipid level is increased in Station-Ill when compared to Station-ll, Station-l and control prawn. There was a significant difference (p 0.01) in the quantitative parameter of lipid content. The results are discussed in details.

Evergreen forest communities distributed within 1580-2600 m above sea level (asl) in Kumaun Himalaya were studied. Quercus leucotrichophoraA. Campus, Q. floribunda Lindl. ex Rehder, Q. semecarpifolia J.E. Smith and Pinus roxburghii Sarg. are the dominant tree species in banj-oak, tilonj-oak, kharsu-oak and chir-pine forests, respectively. Total density for tree, shrub and herb layer varied from 3.7 to 10.5 (individual 100 m-2), 2.0 to 38.8 (individual 100 m-2) and 5.5 to 44.0 (individual m-2), respectively. A total of five forests types (27 stands) were identified in the field on the basis of species richness and species diversity by applying polar ordination method. The diversity value for tree, shrub and herb layer ranged from 0 to 3.62, 0.36 to 3.85 and 1.23to4.21, respectively. Present study indicates the spatial patterns of vegetation in different forest communities at different altitudes.
