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.
