Air Pollution Science - Particulate Matter: Airborne particles such as smoke, dust, dirt, soot, and salt. The sources of these particles are numerous - including vehicles, factories, fires, and any other natural or human activity resulting in the addition of particulates into the air. Ground Level Ozone: Ground level ozone is not directly emitted into the air, but forms when nitrogen oxides (NOx) emissions react with other volatile organic compounds (VOCs) in the presence of heat and sunlight. Emissions from industrial facilities and electric utilities, motor vehicle exhause, and chemical solvents are some of the major sources of NOx and VOCs

Air Quality and Health: Exposure to air pollutants such as particulate matter and ground-level ozone can cause headaches, irritated eyes and sinuses, fatigue, difficulty breathing, chest pains, asthma attacks, irritated throat and increased coughing. Poor air quality can be hazardous to anyone, and it can aggravate health problems such as asmtha, heart disease, and lung disease. Seniors, children and those with compromised immune systems are especially at risk.
