Fine Particles (PM ) Questions and Answers

Fine Particles (PM ) Questions and Answers. Fine particulate matter (PM ) is an air pollutant that is a concern for people''s health when levels in air are are tiny particles in the air that reduce visibility and cause the air to appear hazy when levels are elevated. Outdoor PM levels are most likely to be elevated on days with little or no wind or air mixing.


Assessment of PM Exposure during Cycle Trips in The ...

Jun 03, 2021· In this study, we use 500 dust (PM ) sensors mounted on bicycles to estimate typical PM levels to which cyclists are exposed in the province of Utrecht, the Netherlands, in the year 2020. We use colocated sensors at reference stations to calibrate and validate the mobile sensor data. We estimate that the average exposure to traffic ...


PM What does it mean, and why does it matter?

Sep 01, 2020· The in PM refers to the size of the pollutant, in micrometers. The tinniest thing which the human eye can see is at least millimeters, about the width of a strand of fine air (70 micrometers). For you to see something as small as a micrometer, you need to use microscopes.
