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 webinar, Malvern Panalytical’s application specialist, Dr Dhrubajyoti Gupta, continues from Dr Pathak’s (India’s Central Pollution Control Board) talk. Dr Gupta shares how service laboratories and local municipals can leverage on advanced elemental analysis technology like energy-dispersive X-ray fluorescence. Unlike other elemental analytical methods, XRF is non-destructive. This allows complementary analysis for other parameters like organics, speciation, etc. Paired with Malvern Panalytical’s latest innovation, you can achieve more accurate and fastest profiling in the market of air particulate matter. This supports high throughput analysis for your lab. What's more, our latest Epsilon 4 now comes with factory calibration for air filters analysis. Plus new software features allowing blank subtraction and analysis of samples collected on various filter media using the same calibration.
