Effects of unregulated anthropogenic activities on mixing ratios of volatile organic air pollutants?A case study(Journal of the Air & Waste Management Association)
(D Majumdar, PS Rao, B Dinda Chakraborty, A Srivastava. ,65(9),,1094-1103,Year : 2015)

"During the months of October to November, many important festivals are celebrated in India. Celebration of these festivals are marked by extensive use of fireworks or pyrotechnics, bonfire, incense burning, open air community cooking, and temporary eateries using crude fuel such as coal, wood, kerosene, cow dung, burning of raw/semiwood, and coconut shells. The present study deals with the influence of these unregulated anthropogenic activities on ambient mixing level of volatile organic compounds (VOCs), especially some carbonyl compounds. The study was undertaken in the metropolitan city of Kolkata, India, with very high population density, which is even higher during festival period. The average total carbonyl level at different sites in Kolkata varied from 134.8 to 516.5 μg m−3 in pre-festival season, whereas in post-festival season the same varied from 252.2 to 589.3 μg m−3. Formaldehyde to acetaldehyde ratio altered from 0.62 in pre-festival season to 1.78 in post-festival season. Diurnal variation also altered, indicating variation in source composition of carbonyls. The total ozone forming potential calculated for all 14 carbonyls in pre-festival season increased by 35% in post-festival season. The effect of anthropogenic activities typical to the event of Diwali night characterized by intense execution of pyrotechnics resulted in significantly high level of carbonyl VOCs. Principal component analysis study for the event of Diwali shows clear contribution of the event on certain carbonyl VOCs. The results indicate elevated primary emissions of these pollutants and also their effect on formation of secondary pollutants. The study emphasizes the need of generating awareness among the communities in society as well as need for regulations to minimize the emissions and related hazards to the extent possible"

Hydrodynamic assessment of coastal aquifer against saltwater intrusion for city water supply of Puri, India(Environmental Earth Sciences)
(Ritesh Vijay , P. K. Mohapatra,75(7),,588,Year : )
|
|
Puri city is situated on the east coast of India, and groundwater is the only source available to meet city water supply. Due to increase in population and urbanization of the city, groundwater withdrawal is continuously increasing, which may lead to the movement of saline water interface toward the fresh groundwater. Therefore, the objective of this study was to assess the hydrodynamics of groundwater flow and to predict withdrawal for future water demand of the city without affecting the saltwater intrusion. For this, a groundwater flow model was conceptualized and validated for the present withdrawal coupled with the saltwater intrusion model. To assess the safe yield of groundwater withdrawal, various iterations were carried out with different withdrawal rates and movement of fresh and saltwater interface. This helped in quantifying the future demand of city water supply without affecting the interface between fresh groundwater and saltwater. Based on the simulation results, various measures were suggested to safeguard the groundwater resource against saltwater intrusion.

Megacities in Asia rank high in air pollution at the global scale. In many cities, ambient concentrations of fine particulate matter (PM2.5) have been exceeding both the WHO interim targets as well as respective national air quality standards. This paper presents a systems analytical perspective on management options that could efficiently improve air quality at the urban scale, having Delhi as a case study. We employ the newly developed GAINS-City policy analysis framework, consisting of a bottom up emission calculation combined with atmospheric chemistry-transport calculation, to derive innovative insights into the current sources of pollution and their impacts on ambient PM2.5, both from emissions of primary PM as well as precursors of secondary inorganic and organic aerosols. We outline the likely future development of these sources, quantify the related ambient PM2.5 concentrations and health impacts, and explore potential policy interventions that could effectively reduce environmental pollution and resulting health impacts in the coming years. The analysis demonstrates that effective improvement of Delhi's air quality requires collaboration with neighboring States and must involve sources that are less relevant in industrialized countries. At the same time, many of the policy interventions will have multiple co-benefits on development targets in Delhi and its neighboring States. Outcomes of this study, as well as the modelling tools used herein, are applicable to other urban areas and fast growing metropolitan zones in the emerging Asian regions

Environmental occurrence of CECs poses a great threat to both aquatic life and human health. The aim of this study was to optimize and validate SPE/LC-(ESI)MS-MS method for simultaneous quantitative monitoring of two sub-classes of CECs (pharmaceuticals and hormones) and to estimate the concentrations of select CECs in environmental water samples. For all the tested analytes, recoveries in laboratory reagent water were greater than 81%. Average percent (relative standard deviation) RSD of the analytes in recovery, repeatability, and reproducibility experiments were ≤ 10%. Determination coefficients (r2) of primidone, diclofenac, testosterone, and progesterone were estimated to be 0.9979, 0.9972, 0.9968, and 0.9962, respectively. Limits of detection (LOD) for primidone, diclofenac, testosterone, and progesterone were 4.63 ng/L, 5.36 ng/L, 0.55 ng/L, and 0.88 ng/L, respectively. Limits of quantification (LOQ) for primidone, diclofenac, testosterone, and progesterone were 14.72 ng/L, 17.06 ng/L, 1.766 ng/L, and 2.813 ng/L, respectively. Average recoveries in environmental water and wastewater samples were greater than 74% and RSD were ≤ 7%. Trace levels (68.33-125.70 ng/L) of primidone were detected in four environmental water samples, whereas diclofenac was not detected in any of the tested sample. Trace levels of progesterone were observed in two environmental samples (16.64 -203.73 ng/L), whereas testosterone was detected in STP inlet sample (178.16 ng/L).

A review on organic waste to energy systems in India.(Bioresource Technology)
(Dhar, H., Kumar, S., & Kumar, R.,245. ,,1229-1237,Year : 2017)
|
Waste generation is increasing day-by-day with the growth of population which directly affects the environment and economy. Organic municipal solid waste (MSW) and agriculture sectors contribute towards maximum waste generation in India. Thus, management of organic waste is very much essential with the increasing demand for energy. The present paper mainly focusses on reviewing waste to energy (WtE) potentials, its technologies, and the associated challenges. Different substrates are utilized through various technological options in India. Organic waste has good potential to attain sustainable energy yields with and without affecting the environment. A realistic scenario of WtE technologies and their challenges in line with the existing Indian condition is presented in this paper.

Frequency and genotype distribution of ABCB1 gene polymorphisms among Maharashtrian population of Central India(Xenobiotica)
(Pramanik S, Surendran ST, Devi S, Krishnamurthi K, Chakrabarti T Corresponding Author,446,,579-582,Year : 2014)
|
- Apart from conferring multidrug resistance to cancer cells, P-glycoprotein (P-gp) encoded by the gene ABCB1 (also, known as Multidrug resistance gene, MDR1), plays a major role in drug disposition. Single nucleotide polymorphisms (SNPs) in the ABCB1 gene might contribute to inter-individual and ethnic differences in drug disposition and thereby, could influence the outcome and prognosis of certain diseases.
- India is one of the most ethnically and genetically diverse regions of the world. This study was undertaken with a view to determine the allele and genotype frequencies of C3435T and C1236T polymorphisms in the ABCB1 gene among the Maharashtrian population, residing in the Vidarbha region of central India and compare them with HapMap and other Indian populations. The common synonymous C3435T polymorphism has been found to be associated with lower P-gp functional expression and drug uptake, alone or in conjunction with a few other linked SNPs like C1236T.
- The genotypes of C3435T and C1236T SNPs were determined by PCR-RFLP in 222 healthy and unrelated Maharashtrian individuals.
- According to the findings of this study, the Maharashtrians were found to be not significantly different from the Gujarati Indians in Houston, Texas in the HapMap database.

Object-based image analysis for the impact of sewage pollution in Malad creek, Mumbai, India(Environmental Monitoring and Assessment)
(Shivani Shirke, S. M. Pinto, Vikash K. Kushwaha, Trupti Mardikar, Ritesh Vijay ,188(2),,,Year : )
|
Today, object-based image analysis provides an option for integrating spatial information beyond conventional pixel-based classifications for high-resolution imagery. Due to its rare applicability in pollution assessment, an attempt has been made to assess the spatial extent of sewage pollution in Malad Creek, Mumbai, India. Based on multiresolution segmentation of an IRS P6 (LISS IV) image and the Normalized Difference Turbidity Index (NDTI), the various water quality regions in the creek were classified. The existing literature implies that the reflectance of turbid water is similar to that of bare soil which gives positive NDTI values. In contrast to this, negative values of NDTI are observed in the present study due to the presence of organic matter which absorbs light and imparts turbidity, which is supported by the significant correlation between NDTI and turbidity. A strong relationship is observed between turbidity and water quality parameters, implying the impact of organic matter through discharges of sewage in the creek. Based on the classified regions and the water quality parameters, the extent of pollution was ranked as high, moderate, low and least. The methodology developed in the present study was successfully applied on an IKONOS image for the same study area but a different time frame. The approach will help in impact assessment of sewage pollution and its spatial extent in other water bodies.

Accurate representation of dispersion of air pollutants is essential for environmental management and planning purposes. In the present study, an attempt has been made to investigate the improvement of pollution dispersion using AERMOD model which includes atmospheric boundary layer processes explicitly. Ranchi region, a fast growing urban city with industries and vehicular pollution in the Jharkhand state of India is chosen. Surface micro-meteorological tower data and upper air radiosonde observations are utilized in the study. Surface boundary layer parameters such as friction velocity and sensible heat flux used as input to AERMOD model are obtained from flux-profile relationships and validated with turbulence measurements. The pollutant concentrations includes industrial as well as vehicular sources predicted by AERMOD are validated with the ambient air quality data of Central Pollution Control Board at Ranchi. Results reveal that AERMOD performed well in representing air pollution dispersion over Ranchi region.
