The U.S. Environmental Protection Agency (EPA) describes particulate matter, also referred to as PM, as a mixture of solid particles and liquid droplets found in the air. Some particles, such as dust, dirt, soot or smoke, are large or dark enough to be seen with the naked eye. Others are so small they can only be detected using an electron microscope.
