Measurement and Chemical Speciation of PM10 in Mumbai City (J Environ. Science & Engg) (Abhay singh Salunkhe, Sugandha Shetye,55,4,441-455, Year: 2013)
Mass concentrations of PM10 were high at all locations of Mumbai city in all seasons. From the enrichment analysis, it was observed that high enrichment of metals existed at all sites, the reason for which could be the effects of meteorology and trans-boundary movement of pollutants. Multivariate statistical analysis tools were used to identify common sources, viz. road dust, biomass burning, secondary aerosol, brake wear, residual oil combustion, smelting, natural soil, vehicles tyre wear, and marine aerosol. Findings indicate that most of the sites were dominated by local sources based on activities in the vicinity of the sampling locations.

Development and validation of microbial bioassay for the quantification of potency of the?antibioticcefuroxime axetil (Analytical Methods (Royal Society of Chemistry, UK)) (Nishant Dafale, Uttam Semawl, Piyush Agarwal, G. N. Singh ,5,,690-698, Year: 2013)
Cefuroxime is a semi-synthetic antibiotic of the cephalosporin group and has broad-spectrum antimicrobial activity. HPLC methods, detailed in various pharmacopoeias, are generally used for the quantitative determination of the potency of cefuroxime but are unable to determine its bioactivity against microorganisms. In comparison to HPLC methods bioassay methods are simple and inexpensive however, a bioassay for the determination of both the potency and bioactivity of cefuroxime has not yet been reported in any pharmacopoeia. This article is focused on the development of a bioassay method for the quantification of cefuroxime axetil in pharmaceutical preparations. The bioassay was performed with different microbial strains and Kocuria rhizophila ATCC-9341 was selected as the most susceptible microorganism against cefuroxime axetil. The percent potency of market samples were estimated by a two-level bioassay method. The potency of market samples of Biocef, Ceftech and Ceftum were found to be 100.71% (RSD 1.09%), 101.07% (RSD 1.16%) and 100.44% (RSD 1.08%), respectively. The Biocef intermediate precision RSD between days and between analysts were 1.08% and 1.01%, respectively. The specificity of the bioassay for the analysis of Biocef was also studied in parallel with the Pharmacopoeial HPLC method and the potency was calculated as 101.09%. Results show that a bioassay method can be used for the quality control of cefuroxime axetil in raw materials and pharmaceutical preparations.

Evaluation and analysis of noise levels at traffic intersections of Nagpur city, India (Journal of Environmental Science and Engineering) (Ritesh Vijay, Rishabh Popat, M. Pisode, A. Sharma, M. Kumar, T. Chakrabarti and Rajesh Gupta,55,2,197-206, Year: 2013)
The objective of the present study was to monitor and assess the noise levels at traffic intersections in Napgur city under heterogenic traffic activities. For this, traffic volume and noise level were measured at intersections on highways, major roads and ring road during morning and evening peak hours. Traffic volume was categorized in light, medium and heavy vehicles while noise levels were measured for Lmin, Lmax, Leq, L10 and L90. Equivalent noise was observed in the range of 71.3 to 79.3 dB(A) at the traffic intersections. Due to heterogenic traffic conditions and activities at the intersection like honking, idling, gear noise, bearing noise, breaking noise, tyre-road noise and exhaust noise, no correlation was established between traffic volume and observed noise levels except West High Court road. A strong correlation was found at West High Court road due to controlled traffic flow and less impact of heavy vehicles. Impact of noisy vehicles on general traffic was also assessed at the traffic intersections based on noise pollution levels and traffic noise index. The study suggests that control measures are required at the traffic intersections to minimize noise pollution levels.

Therefore, the objective of this paper was to design and develop a GIS based solid waste management information system as a decision making and planning tool for regularities and municipal authorities. The system integrates geospatial features of the city and database of existing solid waste management. GIS based information system facilitates modules of
Trip Time Comparison of Conventional and Exchange Container Mode for Solid Waste Bins Collection: A Case Study of Ilorin Nigeria (Journal of Environmental Science and Engineering) (A.S. Aremu, Ritesh Vijay O.O. Adeleke,55,1,1-8, Year: 2013)
The use of hauled container system for municipal solid waste collection and transportation often results in socio-economic and environmental impacts which are linearly related to trip time. In this study, trip times for the conventional and exchange container mode of solid waste collection by the hauled container system were evaluated. A trip time model was developed for this evaluation through field studies. The model was applied on ten trips to collect solid waste bins and its transportation to disposal site in the city of Ilorin, Nigeria. The results of the model for both modes were compared and Showed that at 5 % significance level,.the trip time for the conventional mode was greater than the trip time for the exchange container mode. Also, the exchange container mode resulted in haul distance reduction by 3 to 15% and trip time reduction by 2.5 to 13 %. This reduction could help in improving logistics and also reduce the negative, impacts associated with collection operation.
Spatial and temporal assessment of groundwater quality in Puri city, India: a statistical analysis (Asian Journal of Water, Environment and Pollution) (Ritesh Vijay, S S Ramya P. R. Pujari and P. K. Mohapatra,10,2,51-58, Year: 2013)
Puri city is situated near Bay of Bengal where there is a balanced interface of sea water and fresh water near the coast line. The city receives water from the groundwater sources and the quality of ground water is being maintained. The main objective of the paper is to assess the quality of ground water using statistical techniques and the suitability of this water for its utility was verifi ed using Indian drinking water standards. Groundwater samples were collected from various specifi c areas during post and pre- monsoon seasons and analyzed for physico-chemical and bacteriological parameters and compared with standards. The ground water is mainly polluted due to the domestic effl uent, which contains detergents, human and animal excreta, industrial waste and cremation of human and animal bodies. The study showed that concentration of quality parameters were more in the city area as
Geospatial assessment of water quality in creeks and coast of Mumbai India (International journal for scientific research in environemtal sciences ) (Ritesh Vijay, Puja Khobragade, S.R. Kamble, R. A. Sohony Rakesh Kumar ,4,12,61-67, Year: 2013)
Mumbai, the financial capital of India is generating about 2700 MLD of sewage from seven service areas and discharging into adjoining coast, Malad, Mahim, Marve and Thane Creeks. The coastal and creeks water quality is deteriorating due to disposal of partially treated sewage, wastewater from open drains as well as industrial wastewater. The objective of present paper is to assess and evaluate the water quality during low and high tides. 65 samples from west coast including beaches and seafronts, 44 from creeks and 3 from ocean outfalls were collected as per Standard Method. The samples were analysed for physico-chemical and bacteriological parameters and results were compared with SW II standards as prescribed by Central Pollution Control Board, India. The results were incorporated on the GIS platform for further geospatial analysis and visualizati
Feasibility of bioengineered two-stages sequential batch reactor and filtration - adsorption process for complex agrochemical effluent (Bioresource Technology) (Pravin Manekar, Rima Biswas, Chaitali Urewar, Sukdeb Pal, Tapas Nandy,148,,334-342, Year: 2013)
In the present study, the feasibility of a bioengineered two-stages sequential batch reactor (BTSSBR) followed by filtration–adsorption process was investigated to treat the agrochemical effluent by overcoming factor affecting process stability such as microbial imbalance and substrate sensitivity. An air stripper stripped 90% of toxic ammonia, and combined with other streams for bio-oxidation and filtration–adsorption. The BTSSBR system achieved bio-oxidation at 6 days hydraulic retention time by fending off microbial imbalance and substrate sensitivity. The maximum reduction in COD and BOD by heterotrophic bacteria in the first reactor was 87% and 90%, respectively. Removal of toxic ammoniacal-nitrogen by autotrophic bacteria in a post-second stage bio-oxidation was 97%. The optimum filtration and adsorption of pollutants were achieved at a filtration rate of 10 and 9 m3 m?2 h?1, respectively. The treatment scheme comprising air stripper, BTSSBR and filtration–adsorption process
