These are extremely fine particulate matter (PM) particles of diameter less than 1 micron — significantly smaller than PM 2.5 (of diameter 2.5 microns) that have been at the centre of discussions on particulate matter in Delhi’s air. PM 10, PM 2.5 and PM 1 particles make up the total suspended particulate matter.

PM10 is generally subdivided into a fine fraction of particles 2.5  PM 10 (respectively PM 2.5 ) is actually defined as “particulate matter which passes through a size-selective inlet with a 50 % efficiency cut-off at 10 μm  23 Sep 2020 The PM10 index shows the annual mean, averaged over all included sites that had annual data capture greater than or equal to 75%.
