    Mr.Ravinder Singh

    Research Fellow

    “Understanding the Impact of Ultrafine and Fine Aerosols on Respiratory Functions among Healthy and Susceptible Individuals”.

    Ravinder Singh is pursuing PhD in Environmental Engineering in Civil Engineering Department at Indian Institute of Technology Delhi under the supervision of Dr. Gazala Habib (Supervisor) and Prof. Mukesh Khare (Co-Supervisor).

    His research proposal is "Understanding the impact of ultrafine and fine aerosols on respiratory functions among healthy and susceptible individuals". The proposed study aims to link the impact of personal and ambient ultrafine (10-100 nm) and fine (Dp ≤ 2.5 µm) aerosol number and mass concentration with respiratory functions among healthy and susceptible individuals in the age group 20 - 60 years and develop the risk map and estimate the monetary burden of respiratory illness for Delhi.

    Mr.Avdesh Bhardwaj

    Research Scholar

    “Development of a Risk Assessment Model for Cardiovascular illness due to urban aerosol burden over Delhi region”.

    Avdesh’s current research focuses on development of a risk assessment model for cardiovascular diseases (CVD) due to urban aerosol burden over Delhi region.

    His work involves field sampling of volunteer people for their heart’s functioning using personal health questionnaire and equipments like ECG holter systems, blood pressure meter, SpO2 meter, pulse oximeter, etc. and then correlating with the corresponding personal and ambient particulate matter (PM) concentrations and chemical characterization obtained from MINI WRAS, PM sampler and cascade impactors to analyze for CVD like arrhythmia and ischemia. A senior cardiologist from AIIMS Delhi is also involved in this research for medical inputs. Satellite data for aerosol optical depth (AOD) and GIS tools are being used for risk mapping of Delhi according to severity of risk of CVD due to PM concentrations.

    The research intends to provide a model which can be used as a tool for decision makers and stakeholders as far as air pollution and health effects are concerned. It may also help in refining Indian air quality index (AQI) in future.

    Ms.Swati Sharma

    Research Fellow

    “Identification of aerosol sources and their probable locations at urban sites of Jaipur and Dhanbad using chemical characterization data and advance tools”.

    Swati’s current research focuses on understanding the contribution of local and regional sources of aerosol at two selected sites Jaipur and Dhanbad, understanding the chemical profile of soil and its application in improving source apportionment. Also to identify missing sources in regional emission inventory by corroborating the information from source apportionment findings and bottom up emission inventories.

    The scope of research includes prioritization of the source categories for evolving city-specific air pollution management strategies/plan, assess the effect of local and transported dust varying over a region closer to the source and the one far away from the source.

    It also includes profiling the source emission characteristics of various sources typically present in urban areas, building up emission inventories, arrive at appropriate EF for Thar Desert soil and prepare inventory for different air pollutants, their emission rates and pollution loads from various sources along with spatial and temporal distribution and compare the source apportionment results and the existing regional emission inventory. It may also help in refining Indian air quality index (AQI) in future.

    "On-Field Measurement of Aerosol and Characterization of Climate Relevant Species from Biomass Fuel Combustion in Cooking Stoves".

    Annada is a full-time PhD research scholar at Indian Institute of Technology, Delhi. She is a senior research fellow under the UGC-NET fellowship scheme. Her research is directed towards the development of instruments for aerosol measurement, source profile development of stationary sources emission and their effects on climate.

    Her PhD research focuses on “On-field Measurement of Aerosol and Characterization of Climate Relevant Species from Biomass Fuel Combustion in Cooking Stoves” which involves the measurement and collection of PM2.5 and its chemical constituents from burning of biomass fuel in traditional mud cookstoves in rural households.

    The study findings would be beneficial for developing emission load, impact of climate relevant pollutants on climate and health for developing country like India.

    “Emissions of Aerosol and Gases from On-road Light Duty Vehicles”.

    Jaiprakash is a post-doctoral researcher at Indian Institute of Technology, Delhi under a National Carbonaceous Aerosol Programme (NCAP). His research focuses on development of instruments for aerosol measurement, source apportionment and source profile development of air pollution and effect on climate.

    His PhD research focuses on Emissions of Aerosol and Gases from On-road Light Duty Vehicles. It has been discussed about the design, development and evaluation of portable dilution system (PDS) and collect PM2.5 and its chemical constitutes from the light duty vehicles. First, the dilution system was evaluated as criteria of particle losses, mixing performance and particle formation from the two different combustion sources (gasifier cookstove and light duty diesel vehicles).

    He suggested a new approach in aerosol measurement of vehicle emission with dilution system whereas mobile sampling system epitomizes the on-road measurement of emission from the vehicles. There were real time vehicle emission is quite different from the dynamometer study which can beneficial for develop emission load, impact on climate and health for developing country like India.

    The major objectives of the research work:

    a. To conduct a comprehensive study by reviewing literature related to geology of parent metamorphic rock, marble deposits, production of marble (as dimensional stone) and its processing techniques, generation of marble waste and its recycling process including critical analysis of waste minimization and utilization techniques developed by various R and D organizations and their present application status.

    b. To conduct a comprehensive study of the properties of concrete with marble dust and to compare it with control concrete in accordance with the provisions laid down by ASTM standards / IS codes.

    c. To develop an Emerging Cleaner Technology by proposing an Integrated Waste Management System which consented an environmentally and economically advantageous way to sustain the continuous increasing volumes of marble waste products i.e., to turn it out as an important economic resource, capable of promoting the sustainable development.

    d. Finally, to facilitate the availability of raw material locally by the proposed reutilization of marble waste and hence to provide cost benefits to construction sector for its proper growth and the reduction in environmental hazard for Sustainable Development.
