Atmospheric aerosols or particulate matter suspended in air is a very important parameter for air quality monitoring. Respirable particulate matter (RSPM), known as PM2.5 and PM10, are especially damaging to the human health and environment in general. Air Particulate matter comprise of natural particulate matter like crustal dust with signature elements like Al, Si, Fe, Ca; sea spray aerosols having Na, Mg, Cl, S, K, Ca; etc. Besides there are anthropogenic sources of emission, for instance traffic, industries, waste incineration and more which emit toxic elements like Pb, Zn, As, Br, V, Cr, Ni, Cd, etc. into the air. As the effect of toxic elements and their levels in RSPM on public health and environment become increasingly understood, governments and authorities have been implementing tougher restrictions against particulate air pollution.

To effectively uphold these restrictions, authorities need to accurately monitor air quality, and take punitive actions through the identification of the sources of emission. This means being able to accurately gauge elemental concentrations in the RSPM within a certain area in compliance with the strict regulatory norms like US-EPA IO 3.3.

During this air pollution webinar series, we invite experts from Malvern Panalytical and industrial specialists as panel speakers. In our first webinar, Dr Abhijeet Pathak, Scientist from India’s Central Pollution Control Board, sheds more light on the regulations and the methodologies for low limits of detection. He shares knowledge on proper sampling, collection of air filters as well as other practical concerns like the selection of filter matrices. He will also discuss about how to perform non-destructive analysis of the toxic elements. This is with a strong intention on helping service laboratories and governmental agencies to check compliance with strict regulations as well as use it as an effective tool for making emission inventory and source apportionment.

He is presently employed in Central Pollution Control Board, India, the apex regulatory authority in India as Scientist. Engaged in CPCB since 1995, his key responsibilities involve laboratory operations, infrastructure development, Occupational health and safety management, air quality management, Human Resource Development, protocol preparation etc.

He is experienced in the development of laboratory infrastructure (National Trane Organic Laboratory in CPCB). Mr Pathak has been instrumental in the standardization of various methods to expand the analytical capabilities in CPCB. He is the key person in CPCB in both manual and continuous source emission monitoring. Mr Pathak has had 15 Research reports and documents prepared. And has more than 20 research publications, as well as 5 papers presented in international conferences. At present, he is also a faculty member for Green Skill Development Programme in air pollution field.

Mr Abhijit Pathak graduated from the University of Calcutta in 1987. He has worked in various fields of environmental monitoring and management since 1988. Mr Pathak has received overseas training in Canada, Germany, Japan and Austria on both analytical (HAPs and VOCs, Dioxins and Furans) and modelling (Receptor modeling for Source Apportionment) fronts.

Dhrubajyoti Gupta (PhD), application specialist for Malvern Panalytical, based in India

Dr Gupta’ s specialty is in elemental analysis using X-ray fluorescence as well as fusion sample preparation. He has more than 18 years of elemental analysis in environmental, research and other industrial applications. In his role, he is frequently involved in not only applications support but also the training and commissioning of XRF instrumentation for the laboratory and field. Prior to joining Malvern Panalytical, he was a Research Professor and Korean Research Fellow in the Aerosol Micro-analysis laboratory at Inha University, Incheon, South Korea and Post-doctoral fellow at Saha Institute of Nuclear Physics, Kolkata, India where he was involved in development of analytical methodologies for characterization of atmospheric aerosols and other environmental samples like soil, solid waste and water. He has also worked with the Industry in water and wastewater treatment as well as chemical processing.
