Aggravation of CoVID-19 infections due to air pollutant concentrations in Indian cities
(Springer Science and Business Media B.V., 2023) Asha Sunilkumar; Shishir Kumar Singh; Amit Kumar Mondal; Paulami Ghosh; Surajit Mondal
The CoVID-19 infections began rising worldwide during the initial weeks of March 2020, reacting to which the Government of India called for nationwide lockdown for ~ 3 weeks. The concentration of pollutants during the lockdown were compared with pollution levels recorded during the preceding year for the same time frame. A direct relationship was established between the high level of air pollutants (PM2.5, PM10, NO2 and SO2) and CoVID-19 infections being reported in the Indian cities. The correlation indicates that the air pollutants like PM2.5, PM10, NO2 and SO2 are aggravating the number of casualties due to the CoVID-19 infections. The transmission of the virus in the air is in the form of aerosols; and hence places which are highly polluted may see a proportionate rise in CoVID-19 cases The high-level exposure of PM2.5 over a long period is found to be significantly correlated with the mortality per unit confirmed CoVID-19 cases as compared to other air pollutant parameters like PM10, NO2 and SO2. © 2023, The Author(s), under exclusive licence to Korea Spatial Information Society.
Analyzing the interconnected dynamics of domestic biofuel burning in India: unravelling VOC emissions, surface-ozone formation, diagnostic ratios, and source identification
(Royal Society of Chemistry, 2024) Arnab Mondal; Surajit Mondal; Paulami Ghosh; Papita Das
Burning biomass fuels in Indian households is a common and cost-efficient way to generate energy for various domestic tasks. However, this practice is a significant source of non-methane volatile organic compounds (NMVOCs) released into the atmosphere, impacting local and global air quality. The substantial quantities of NMVOCs produced from burning biofuels at home can have adverse effects on climate and human health worldwide. This review focuses on exploring the processes involved in domestic biofuel combustion, detailing different stages of burning, and discussing the tools and techniques required to measure NMVOC emissions accurately. It also aims to identify potential emission sources through methods such as diagnostic ratios and PCA analysis. By striving to reduce NMVOC emissions from household biofuel burning, the goal is to provide a basis for informing policymakers in developing effective regulations and policies to address this environmental issue. © 2024 RSC.
Innovative approaches for carbon capture and storage as crucial measures for emission reduction within industrial sectors
(Elsevier Ltd, 2024) Debajyoti Bose; Riya Bhattacharya; Tanveen Kaur; Ravindra Pandya; Abhijeeta Sarkar; Aritra Ray; Surajit Mondal; Arnab Mondal; Paulami Ghosh; Rhea Ishani Chemudupati
Carbon capture and storage represented as CCS, is a technique that can be used to cut down on emissions of CO2 from industrial sources. These mechanisms can balance the excess fossil fuel usage and lead to effective carbon capture from the atmosphere and storing it in safe spaces. This can negate global warming and send the carbon back to geological spaces inside the earth. This review covers the operational mechanism of such technologies from its inception to the material innovation along with the transport of CO2 and its storage options. Breakthroughs in recent years have made it possible to design effective carbon capture and safe spaces for its storage. A comprehensive worldwide case studies are presented for both successful CCS project implementation and their environmental impact assessment. Lessons learned from these case examples are reflected through the challenges and policy hurdles with its impact on the global economy. An outlook is provided for the role of CCS in net zero emissions, renewables integration and advancing CCS research. By leveraging innovation across capture, utilization, and storage stages, CCS holds immense potential to play a transformative role in combating climate change and achieving global sustainability goals. © 2024 The Author(s)
Overcoming water, sanitation, and hygiene challenges in critical regions of the global community
(KeAi Communications Co., 2024) Debajyoti Bose; Riya Bhattacharya; Tanveen Kaur; Ritesh Banerjee; Tanya Bhatia; Aritra Ray; Bhavika Batra; Arnab Mondal; Paulami Ghosh; Surajit Mondal
This review provides a critical analysis of the global water and sanitation crisis, as well as how community-based approaches have led to innovative water management solutions. Regions of sub-Saharan Africa, south Asia, the Middle East, and island countries have been taken as models to understand mitigating crises related to water, sanitation, and hygiene (WASH) services. Selected WASH cases based on specific inclusion and exclusion criteria that highlighted finance, sustainability, and community engagement. The review analyses methods through which communities below the poverty line, living in densely populated areas, war zones, and island countries can foster innovation, and collaborations. © 2024
