Air Quality Mapping using GIS and Economic Evaluation of Health Impact for Mumbai City, India(Journal of the Air & Waste Management Association)
(Awkash Kumar, Jorgen Brandt, Anil Kumar Dikshit and Rashmi S Patil,66,5,470-481,Year : 2016)
|
Mumbai, a highly populated city in India, has been selected for air quality mapping and assessment of health impact using monitored air quality data. Air quality monitoring networks in Mumbai are operated by National Environment Engineering Research Institute (NEERI), Maharashtra Pollution Control Board (MPCB), and Brihanmumbai Municipal Corporation (BMC). A monitoring station represents air quality at a particular location, while we need spatial variation for air quality management. Here, air quality monitored data of NEERI and BMC were spatially interpolated using various inbuilt interpolation techniques of ArcGIS. Inverse distance weighting (IDW), Kriging (spherical and Gaussian), and spline techniques have been applied for spatial interpolation for this study. The interpolated results of air pollutants sulfur dioxide (SO2), nitrogen dioxide (NO2) and suspended particulate matter (SPM) were compared with air quality data of MPCB in the same region. Comparison of results showed good agreement for predicted values using IDW and Kriging with observed data. Subsequently, health impact assessment of a ward was carried out based on total population of the ward and air quality monitored data within the ward. Finally, health cost within a ward was estimated on the basis of exposed population. This study helps to estimate the valuation of health damage due to air pollution.

Indoor and Outdoor Carbon Concentration of Fine Aerosol in a Mega City- Mumbai(Indian Journal of Air Pollution Control)
(, XIV ,1,5-15,Year : 2014)
|
The present study monitored indoor and outdoor fine particles, PM$_(2.5), in four sites categorized as control (C), kerb (K), residential (R) and industrial (I) within Mumbai, India during summer, post-monsoon and winter seasons during year 2007-2008. The average outdoor PM$_(2.5) mass concentrations at C, K, R and I site were 77.6±18.19, 96.3±35.47, 88.9±39.12, 96.8±24.53 microgram/m$^3 and indoors was 93.7±4.99, 99.1± 47.4, 69.8±27.02, 76.6±28.05 microgram/m$^3 respectively. The Indoor/Outdoor (I/O) ratio for PM2.5 was 1.24±0.23, 1.01±0.12, 0.8±0.07 and 0.78±0.18 at the respective sites. Elemental Carbon (EC) and Organic Carbon (OC) values in fine aerosol have been estimated for indoor and outdoor air using thermal optical reflectance method. The average annual OC contributions at C, K, R and I sites outdoors were 25.15%, 33.07%, 36.86%, 30.04% respectively and indoors were 32.45%, 28.55%, 35.12%, 25.19% respectively. On the other hand, for the same sites outdoor EC contributions were 6.66%, 11.11%, 8.73%, 7.86% and indoor were 9.99%, 13.23%, 9.46% and 4.72% respectively. The I/O ratio for OC was 1.66±0.6, 0.96±0.2, 0.79±015, 0.78±0.41 whereas for EC was 1.73±0.66, 1.21±0.29, 0.73±0.39, 0.48±0.24 respectively. Pearson correlation coefficients were estimated to understand the correlation among indoor and outdoor pollutant. At kerbsite all the pollutants were highly correlated, whereas at the rest of the sites a mixed correlation was observed depending upon the site. This study indicated that vehicular emission source which operates close to the ground level has more impacts on household close to the traffic which may affect health exposures. The industrial indoor site was cleanest among all the four sites as it was a high rise apartment with good ventilation. The indoor concentration was higher than outdoor concentration although site selected was supposed to be a control area in Mumbai city. Findings in this study were also compared with other international studies.

Noise mapping is a well-established practice among the European nations, and it has been follow for almost two decades. Recently, as per guidelines of the Directorate General of Mines Safety (DGMS), India, noise mapping has been made mandatory in the mining expanses. This study is an effort to map the noise levels in nearby areas of mines in the northern Keonjhar district. The motive of this study is to quantify the existing A-weighted time-average sound level (LAeq, T) in the study area to probe its effects on the human dwellings and noise sensitive areas with the probability of future development of the mines, roads, and industrial and commercial zone. The LAeq, T was measured at 39 identified locations, including industrial, commercial, residential, and sensitive zones, 15 open cast mines, 3 major highways, and 3 haulage roads. With the utilisation of Predictor LimA Software and other GIS tools, the worked out data is mapped and noise contours are developed for the visualisation and identification of the extent and distribution of sound levels across the study area. This investigation discloses that the present noise level at 60% of the locations in silence and residential zone exposed to significantly high noise levels surpasses the prescribed limit of Central Pollution Control Board (CPCB), India. The observed day and night time LAeq, T level of both zones ranged between 43.2–62.2 dB(A) and 30.5–53.4 dB(A), respectively, whereas, the average Ldn values vary between 32.7 and 51.2 dB(A). The extensive mobility of heavy vehicles adjoining the sensitive areas and a nearby plethora of open cast mines is the leading cause of exceeded noise levels. The study divulges that the delicate establishments like schools and hospitals are susceptible to high noise levels throughout the day and night. A correlation between observed and software predicted values gives R2 of 0.605 for Ld, 0.217 for Ln, and 0.524 for Ldn. Finally, the mitigation measure is proposed and demonstrated using a contour map showing a significant reduction in the noise levels by 0–5.3 dB(A).

SENSITIVITY ANALYSIS OF A MANGROVE ECOSYSTEM MODEL(Journal of Environmental Systems)
(P. KHANNA
,,,26,Year : 1998)
|
Mangrove ecosystems represent one of the most important ecosystems in terms of commercial use, inasmuch as their productivity is comparable to that of coral reefs and sea grass beds. In the present article, a comparative analysis is presented for delineating the ecological significance of mangrove ecosystems. Then, a mangrove ecosystem computer model is analyzed, and sensitivity analyses identify key parameters in the design of environmental management plans aimed at optimal and judicious use of mangroves. Analytical expressions are derived for steady state conditions. Moreover, conditions for ecological feasibility are also ascertained. Tidal action and nutrient inputs from terrestrial run-off turn out to be one of the most important controlling factors with respect to detritus export and nutrient cycling.

An insight into phage diversity at environmental habitats using comparative metagenomics approach(Current Microbiology)
(Krupa M. Parmar, Rajesh R. Pal, Nishant A. Dafale, Hemant J. Purohit,75,,32-141 ,Year : 2018)

Bacteriophages play significant role in driving microbial diversity; however, little is known about the diversity of phages in different ecosystems. A dynamic predator–prey mechanism called ‘‘kill the winner’’ suggests the elimination of most active bacterial populations through phages. Thus, interaction between phage and host has an effect on the composition of microbial communities in ecosystems. In this study, secondary phage metagenome data from aquatic habitats: wastewater treatment plant (WWTP), fresh, marine, and hot water spring habitat were analyzed using MG-RAST and STAMP tools to explore the diversity of the viruses. Differential relative abundance of phage families—Siphoviridae (34%) and Myoviridae (26%) in WWTP, Myoviridae (30%) and Podoviridae (23%) in fresh water, and Myoviridae (41%) and Podoviridae (8%) in marine—was found to be a discriminating factor among four habitats while Rudiviridae (9%), Globuloviridae (8%), and Lipothrixviridae (1%) were exclusively observed in hot water spring. Subsequently, at genera level, Bpp-1-like virus, Chlorovirus, and T4-like virus were found abundant in WWTP, fresh, and marine habitat, respectively. PCA analysis revealed completely disparate composition of phage in hot water spring from other three ecosystems. Similar analysis of relative abundance of functional features corroborated observations from taxa analysis. Functional features corresponding to phage packaging machinery, replication, integration and excision, and gene transfer discriminated among four habitats. The comparative metagenomics approach exhibited genetically distinct phage communities among four habitats. Results revealed that selective distribution of phage communities would help in understanding the role of phages in food chains, nutrient cycling, and microbial ecology. Study of specific phages would also help in controlling environmental pathogens including MDR bacterial populations using phage therapy approach by selective mining and isolation of phages against specific pathogens persisting in a given environment.

"This paper reviews how active research inWest Bengal has unmasked the endemic arsenismthat has detrimental effects on the health of millions of people and their offspring. It documents howthe pathways of exposure to this toxin/poison have been greatly expanded through intensive application of groundwater in agriculture in the regionwithin the Green Revolution framework. A goal of this paper is to compare and contrast the similarities and differences in arsenic occurrence in West Bengal with those of other parts of the world and assess the unique socio-cultural factors that determine the risks of exposure to arsenic in local groundwater. Successful intervention options are also critically reviewedwithemphasis on integrative strategies that ensure safewater to the population, proper nutrition, and effective ways to reduce the transfer of arsenic from soil to crops. While no universal model may be suited for the vast areas of the world affected with by natural contamination of groundwater with arsenic, we have emphasized community-specific sustainable options that can be adapted. Disseminating scientifically correct information among the population coupled with increased community level participation and education are recognized as necessary adjuncts for an engineering intervention to be successful and sustainable."

Geospatial assessment of urban sprawl and landslide susceptibility around the Nainital lake, Uttarakhand, India(Environment, Development and Sustainability)
(Jaydip Dey, Saurabh Sakhre, Ritesh Vijay, H. Bherwani, Rakesh Kumar ,,,,Year : 2020)
|
Landslide is one of the challenges faced by mountainous regions due to natural phenomena and human activity. Nainital district in the state of Uttarakhand is one of the popular tourist spots in India. It is situated in a lesser Himalayan belt facing experiences number of landslides every year. This region comes under the Main Boundary Thrust and Main Central Thrust which are considered to be very sensitive for landslides. Landslide susceptibility mapping is a proficient tool to identify vulnerable zones for landslides. Remote sensing and geographic information system are very effective tools for collecting, analysing and interpreting land use data, and on the other hand, multi-criteria valuation (MCE) allows users for decision-making by considering various factors affecting the process of the landslide. The MCE technique was applied considering present land use/land cover, slope, drainage, lithology, geomorphology, and type of soil. Overlay analysis and land susceptibility mapping was carried out for the area around the Nainital lake. The study concludes with hot spot analysis and recommends mitigation measures like geotextiles, retaining walls and strict building by-laws for preventing landslides.

(Manda Karunakar Reddy, Mareddy Sumathi,662-667,,662-667,Year : 2011)
|
The aerodynamic diameter of an air borne particle is the key property in determining its respiratory deposition. The study aim to assess PM2.5 level and its size distribution at 5 traffic junctions located along the lateral highway connected to NH-202. A cascade impactor has been used to measure the size function range of PM2.5 apart from PM10 of atmospheric dust particles in air being PM2.5 is concern with respect to effect on human health and is able to tend deeply into the respiratory tract reaching the lungs. It is observed that weight % of PM2.5 values are in the range of 40% - 60% of PM10 and few values of PM2.5 are exceeding the standards prescribed by CPCB. It is concluded that free flow of traffic is main concern and maintenance of road should be carried out during low traffic hours.
