Particulate pollution (PM-10 and PM-2.5) is made up of tiny particles in the air. It occurs year-round, but is dominant during winter months.

Ground-level ozone pollution thrives with sunny days and high temperatures. It is formed when sunlight causes a chemical reaction in volatile organic compounds (VOCs) and nitrogen oxides (NOx). It is harmful and should not be confused with the “good” ozone in the upper atmosphere. Reducing activities that contribute to the production of ozone is one of the ways to prevent air pollution. Making the following tips part of your daily routine in the summer, especially during pollution advisories and health watches, will help make more clean air.
