Abstract: By far and away the most significant degradation of a pesticide occurs due to microbial degradation. This type of degradation occurs when microorganisms such as fungi and bacteria use the technical grade pesticide as a food. Microorganisms play an important role in the bioconversion and total breakdown of pesticides in the Environment. This study was conducted to assess the pesticide degradation ability of Bacillus and pseudomonas sps. The screening test conducted to reveal the ability to degrade Chlorpyrifosand Methyl parathion shows that Bacillus sps was more predominant in biodegradation than Pseudomonas. The pesticide degradation was estimated by optical density method. Methyl parathion was highly degraded compared to chlorpyrifos. This study clearly proves that pesticides and their residue degradation can be accelerated by employing microbes which can be effectively utilized both as biocontrol agent and soil cleanser.

Abstract: Objectives of this research were two folds: 1) to investigate the TVOCs in the communities near Mab Ta Phut Industrial Estate and 2) to study the relationships of TVOCs and traffic volume, temperature, air velocity. The instrument used for the detection of TVOCs is Photovac certified by the US. EPA and calibrated by the laboratory of the Airport Authority of Thailand which certified by the ISO 17025 before being used in the fieldwork. Data analysis was accomplished with mean, cross correlation coefficient and multiple regression analysis. The detection result of TVOCs in three communities throughout a week during September, 1-7, 2012 (morning, afternoon and night) found that the average ambient concentration of TVOCs in Nong Fab Community was the highest, followed by Mab Chalud and Nong Fab Communities, (0.14, 0.06 and 0.04 ppm), respectively. Hypothesis testing found that traffic volume and temperature correlated positively with concentration of TVOCs, but air velocity did negatively with that. Finally, the prediction model of TVOCs has been presented.

Abstract: The results of 210Pb, 210Bi and 210Po activity concentrations in the precipitation samples from the Kapar coastal area were presented and discussed in relation to their sources and application as tracers for the estimation of the residence time of particles in the lower atmosphere. It was concluded that the mean ratio was 0.53 for 210Bi/ 210Pb, higher than the natural level, 1.0. These results may be due to additional 210Bi and 210Po excess. The presence of 210Pb, 210Bi and 210Po varied with time and this may be due to the variety of rainfall events and changes in aerosol content. Furthermore, the influence of dry deposition and wet deposition could be the major reasons as this particle reactive radionuclide tends to attach itself to aerosol particles. Thus the contribution from the factory may also be important as the amount of dust and coal burning will influence radionuclide activities. A comparison of mean radioisotope concentration profiles with a theoretical model indicates that the mean aerosol residence time in the atmosphere at the Kapar coastal area is 19 days from Pb-Bi derived calculations and 8 months from Pb-Po derived calculations.

Abstract: An exhaust noise of automotive engine is the main component of noise pollution in the urban environment, with the ever increasing population density of vehicles on the road. The suitable design and development of exhaust muffler will help to reduce the noise level in the urban environment. The present work aims at predicting the noise level of an exhaust muffler with perforated end plate used in a multi cylinder diesel engine. The Ashok Leyland Hino (hin-ed-wo6d) six-cylinder diesel engine was considered for test purposes. Different configurations of Mufflers are developed and studied exhaust noise level of the engine to vary the load and speed. In addition, the current studies were compared with the conventional muffler in term of noise reduction, brake thermal efficiency and brake specific fuel consumptions. The newly developed muffler was found to be good in noise reduction, specific fuel consumptions and acoustic performance compare with existing muffler.

Abstract: Majority of the disease producing pathogens derives from human or animal faeces, and is transmitted through the faecal-oral route. Although both animal and human faeces are threats to human health, human faeces are generally the most dangerous. Infectious diseases caused by pathogenic bacteria, viruses and parasites (e.g. protozoa and helminthes) are the most common and widespread health risks associated with drinking-water. The public health burden is determined by the severity of the illness associated with pathogens, their infectivity and the population exposed. To find out the contamination of stool samples with pathogens a study has been made on stool samples collected from 39 wards of Shivpuri town, M.P., India.

Abstract: An attempt has been made to study the effects of geochemical pollution in river water. It is revealed that the unsuitable physico-chemical characteristics triggered by thermal stratification accompanied by of river water led to a creation of a ' fatal zone ' for the fish at village Paragaon in the Bhima basin (India).The environmental study of the river water quality suggests that the temporary bunds constructed across the river bed modified the aquatic environment. As a result, during the warm and dry climatic seasons, the temporary stagnant water conditions gave rise to reduction of dissolved oxygen (DO) and also increased toxicity. Simultaneous enhancement in thermal stratification lead to death of fish fauna at restricted locations. Conversely, there was abundance of such fish fauna in the downstream of the river and also in the back waters of the Ujjani dam, where identical physico-chemical and hydro-dynamic conditions existed except the thermal stratification. It is inferred that the addition of fresh water supply (both surface and groundwater) from the adjacent region around Pargaon retained of toxicity are the root causes for the fish deaths. Such toxicity may be reduced by minimizing the thermal stratification and increasing the fresh water supply at the diseased sites.

Abstract: The objective of present study deals with Insilco acetyl cholinesterase inhibitory analysis of Organo phosphorous pesticide Dimethaoate (O, o-dimethyl S-[2-(methyl amino)-2-oxoethyl] phosphorodithioate). To comprehend the mechanism of protein and pesticide binding and interaction, molecular docking was performed for the compounds predicting the probable binding mode of the inhibitors to the protein. Molecular docking studies were carried out using Auto Dock 4.0 and in silico acetyl cholinesterase inhibitory activity was performed using acetyl cholinesterase as the receptor. Among the active residues identified, the binding confirmation confirms that residues TYR337: OH of the acetyl cholinesterase showed lowest binding energy value about -5.98 kcal/mol. It is concluded that Dimethoate binds strongly with acetyl cholinesterase inhibiting the enzyme that hydrolyzes the neurotransmitter acetylcholine (A Ch) at cholinergic synapses in the nervous system.

Abstract: The largest problem the world is witnessing today is climate change which will significantly alter the distribution and function of most of the world ' s natural systems. The carbon footprint of India is very small with per capita emission of only 1.7 tonnes per annum and modeling studies indicate that even in 2030 the per capita emission will not exceed 3.7 tonnes. India as a developing country is constructively engaged in various negotiations with the most recent one at Durban. It has taken additional mitigation actions in a regime of international transparency. It also cannot ignore the primary goal of social and economic development. At a recently concluded meeting of 17th Conference of Parties in Durban, South Africa, India indicated that the country although is fulfilling the obligations of Kyoto yet it is time the developed countries step in to fulfill their commitment under UNFCC and Kyoto Protocol. This paper examines the common but differentiated responsibility of a developing nation as India and also tries to assess whether the actions adopted by the Indian Government are adequate to sustain the climate change regime.

Abstract: Pseudomonas is the well known predominat rhizosphere bacteria having novel features in improving plant growth. Pseudomonas due to their multiple beneficial effects on plant growth and soil fertility, eco-friendly nature, low-cost effectiveness, an attempt was made to identify efficient fluorescent Pseudomonas (PF) isolates with multiple activities, a total of eighteen bacterial isolates were obtained from rhizospheric soils of maize, sorghum, groundnut, chilli, castor and tomato crops. These isolates were biochemically characterized and screened in vitro for their plant growth promoting traits like phosphate solubilization, production of indole acetic acid (IAA), Hydrogen cynide (HCN) and siderophore. Due to the production of HCN and siderophores, fluorescent Pseudomonas isolates inhibited the growth of Fusarium oxysporum f.sp.ricini Out of eighteen, three isolates showing promising PGP traits with biocontrol activity were selected and tested further for compatibility with the commonly used agrochemical viz., fungicides, insecticides and herbicides at recommended and half recommended dosages. Among the three isolates tested, STPF-14 was found to be highly compatible with all the chemicals at their recommended and half recommended dosages. So the isolate of P.fluorescens (STPF-14) was evaluated (alone and in combination) under greenhouse conditions for efficacy in suppressing wilt incidence and promoting plant growth in castor.

Abstract: A poly bag experiment was conducted at Department of Agricultural Microbiology and Bioenergy, College of Agriculture, Rajendranagar, Hyderabad during 2011-12 to study the effect of FYM and VAM on yield, nutrient content and antioxidant activity of spinach. Recommended dose of chemical fertilizers (100 % RDF, 50 % RDF), farm yard manure and mycorrhizae were applied to the soil according to the treatments imposed. All green variety of spinach seeds (2) were sown in polybags and watered. The crop was harvested around 40 days after sowing. The results revealed that yield was highest in FYM+100 % RDF followed by 100 % RDF +FYM+VAM. Addition of FYM to the treatment VAM +100 % RDF significantly increased the yield. Highest dry weight observed in 50 % RDF+FYM+VAM followed by FYM +100 % RDF followed by 50 % RDF+FYM+VAM. Highest chlorophyll content was observed in FYM+100 % RDF showed maximum number of leaves there was no significant difference among the treatments. Highest vitamin C content was recorded in 100 % RDF+FYM +VAM and 50 % RDF+FYM+VAM. Highest phenolic content was observed in 50 % RDF +FYM+VAM followed by 100% RDF +FYM+VAM. Highest antioxidant activity and total carotene content were found in 50 % RDF+FYM+VAM and 100 % RDF+FYM+VAM treatments respectively. No significant difference was observed among the treatments interms of proline content. Highest nitrogen, phosphorus and potassium uptake was observed in the treatment with 50 % RDF+FYM+VAM. The uptake was significantly increased when FYM was added to the VAM +100 % RDF treatment. Lowest uptake of N, P and K content was found in VAM treatment. The results obtained in the present experiment indicate that the FYM or VAM or RDF alone did not help in higher yield. Though FYM with RDF gave the best results than RDF alone, use of VAM with FYM and RDF gave the best results in terms of yield, antioxidant activity, and vitamin C content.
