PM stands for particulate matter: the expression for a combination of solid particles and liquid droplets present in the air, often called particle pollution. Many of the objects, such as ashes, soot, or smoke, are huge or dark enough for the naked eye to see. Others are so small that only an electron microscope can be used to locate them
An air quality index (AQI) is a measure of the quality of air in the environment which is used by regulatory agencies and governmental authorities to inform the people about the air pollution and the currently and the forecast situation of air pollution of any area. Public health risks correspond to these air quality indices, the risks increase with an increase in AQI. Each country has its own air quality indices depending upon its national air quality standards. The AQI is a metric for daily air quality monitoring. It shows you how safe or dirty the air is, and what might be a problem for you with related health consequences. Air quality indices range from 0 to 500. Higher value...

Potentially even spend some time with buddies you have not seen in a while. If you are heading out to play for the first time this season, you will still enjoy the...
