Perturbation in ambient particulate matter (PM1, PM2.5, PM10) and black carbon (BC) concentrations was studied during a firecracker bursting episode in Diwali (Festival of Lights) celebrations in Nagpur, India. Firecracker bursting resulted in greater escalation in fine particulates over coarse particulates while PM2.5 was found to be dominated by PM1 concentration. On the Diwali day, daily mean concentration of PM2.5 and PM10 exceeded Indian National Ambient Air Quality Standards by over 1.8 and 1.5 times, respectively, while daily mean BC concentration on the same day was almost two times higher than the previous day. The BC/PM1 ratio reduced remarkably from about 0.26 recorded before firecracker bursting activity to about 0.09 during firecracker bursting on Diwali night in spite of simultaneous escalation in ambient BC concentration. Such aberration in BC/PM1 was evidently a result of much higher escalation in PM1 than BC in ambient air during firecracker bursting. The study highlighted strong perturbations in ambient PM1, PM2.5, PM10 concentrations and BC/PM1 during the firecracker bursting episode. Altered atmospheric BC/PM1 ratios could serve as indicators of firecracker-polluted air and similar BC/PM1 ratios in local and regional air masses might be used as diagnostic ratios for firecracker smoke.

Geospatial assessment of land surface temperature in Nagpur, India: an impact of urbanization(Environmental Earth Sciences)
(Saurabh Sakhre, Jaydip Dey,Ritesh Vijay,Rakesh Kumar,79,,226,Year : 2020)
|
Temperature is one of the factors which affects the meteorological phenomenon prevailing in an urban area and ultimately leads to climate change and global warming. Measurement of surface temperature with conventional temperature sensors is tedious, has single point value and expensive. Satellite data of 2005, 2008, 2010 and 2016 are used to assess the land use land cover (LULC) and to measure the land surface temperature (LST) during the hottest month of May in Nagpur city, India. Based on the image analysis, it is observed that there is an increase in the average temperature from 40.0 to 44.6 ºC. This may be due to an increase in built-up area from 55.5 to 69.8% during 2005 to 2016, respectively. It has also been revealed that the outskirts of the city are hotter than the central portion of the city as there is more barren land on the outskirts. Results were compared to ambient temperature sensor that showed good agreement between temperature retrieved from satellite and temperature sensor. The study suggests that urban areas should be developed intermixed with vegetation and plantation and provisions of green belt along the city roads, highways and ring roads. Based on LST and LULC analysis, a green belt of 30 m along both sides of the road would lower the road temperature by 9.3 ºC from existing temperature of 44.7 ºC. This would help in lowering down the average temperature of the city.

"The present work encompasses the geo chemical studies of groundwater occuring in limestone terrain around ACC Ltd. Kymore, Katni. The study is based on chemical analysis and interpretation of samples collected from respective localities. The results are presented in terms of their specific use for drinking purposes. It has been observed that the chemical analysis carried out during the study period (Aplil, 2001 - December 2002) for various physico-chemical characteristics indicate in general the surface water and ground water quality of the study area is quite normal as per BIS and WHO norms. In certain cases, local anomalies in some elements are observed. It is also observed that the hardness of water is slightly high at some villages due to the limestone as aquifier but it is well within the standard limits of drinking water. The influence could be attributed to the geological and hydro-geological control of the quifer system on the qater quality with specific reference to the limestone/shale formation."

India where festivals and functions are incomplete without blare sound of loudspeakers in every nook and corner introduces noise as a pollutant in the environment. Contributing to such activities, major sources of noise seeks to be the traffic noise which also entails noise produced by constant honking scenario of the vehicles. Due to existing heterogeneous condition of traffic scenario in India, the research was carried out on National highway whichemphasis on characterization of traffic and honking noise. Traffic volume, noise metrics with statistical indicators (Leq, L10, L90, Lmax, Lmin) were observed during morning, afternoon and evening session. Study includes manual quantification of honking incident of different categories of vehicle (light and medium), which exhibit positive relationship with observed Leq level. As per traffic volume data collected, 60-64% light category vehicles contributed 60-70% honks and medium category vehicle volume of 29- 32% contributing 30-40% of honks. Statistical analysis and

Hydrogen transportation using liquid organic hydrides: A comprehensive life cycle assessment(Journal of Cleaner Production
)
(Rajesh B. Biniwale,183:,,988-997,Year : 2018)
|
The liquid organic hydride (LOH-H2) technology has gained significant attention for hydrogen transportation. There are, however, open questions on LOH-H2 environmental performance due to the presence of energy-intensive dehydrogenation and separation steps. Therefore, in this study, we have conducted the life cycle assessment of LOH-H2 to quantify its total environmental footprint and benchmark the results with conventional compressed hydrogen technology (G-H2). In the LCA model, we have used the ReCiPe end point method and the IPCC 2013 global warming potential methods. Our results suggest that the dehydrogenation-cum-separation stage in LOH-H2 contributes to the largest environmental footprint and the dehydrogenation conversion should be maintained above 99% to gain environmental advantage over G-H2. Through breakeven point analysis, we found that LOH-H2 could be an environmentally favorable option when H2 is transported beyond 395?km, 365?km, 295, and 265 for USA, Europe, China and India respectively.

(,Volume 57,3,271-286,Year : 2015)
|
Conservation and management of water resources is critically important for a vast and fast developing country like India. However, rapidly increasing population and continuous betterment of lifestyle has put tremendous pressure on water resources around major cities leading to alarmingly reduction in per capita water availability. Moreover, increasing fluctuations in precipitation over the country has only aggravated the problem. This paper presents the current and future water scenario in India and also discusses the impacts of various factors like population, pollution, mismanagement, climate change, government laws & regulations etc. on water resources and its availability. While emphasis has been laid on water productivity and various government initiatives, the paper also discusses and analyzes limitations in water management. Based on study and analysis, the paper finally recommends Best Management Practices (BMP) & Best Available Technologies (BAT) used & practiced worldwide for effective & efficient water management in India. The paper also highlights the importance of Public Private Community Partnership (PPCP) along with the recently developed monitoring tools and data information systems for sustainable & effective water resource management to meet present requirements without compromising the future needs.
