Particulates
(source: EPA) Background from Wikipedia Aerosol pollution over Northern India and Bangladesh - Photo: NASA Particulates, alternatively referred to as particulate matter (PM), aerosols or fine particles, are tiny particles of solid (a smoke) or liquid (an aerosol) suspended in a gas. They range in size from less than 10 nanometres to more than 100 micrometres in diameter. This range of sizes represent scales from a gathering of a few molecules to the size where the particles no longer can be carried by the gas.
