Pollutant and Greenhouse gas An air pollutant is a material in the air that can have adverse effects on humans and the ecosystem. The substance can be solid particles, liquid droplets, or gases.
Agency Main Content Air quality at a glance The Environmental Protection Agency defines air pollution as "The presence of contaminants or pollutant substances in the air that interfere with our health or welfare, or produce other harmful environmental effects.

Cars and trucks are the number one Air quality of air pollution in Oregon. The Air Quality Index is a scale used to report actual levels of ozone and other common pollutants in the air. The higher the AQI, the higher the health concern.
The AQI is divided into categories that correspond to different levels of health concern. The Portland region sometimes violated the national air quality standard for ozone smog by as much as 50 percent!
They focused on cars and trucks. This included new federal emission standards for vehicles, the launch of the vehicle inspection program in Portland and transit improvements.
Other efforts included reformulating gas to make it less polluting and placing additional regulations on industry. Should we be concerned about air quality?
Not only are more vehicles on the road, but there are more people painting, using toxic household products, mowing their lawns and burning woodstoves.
Also, more individuals are driving larger, less fuel-efficient vehicles. This results in emissions from these sources accumulate in our air, requiring a greater effort from everyone to keep the air clean and protect our health.
How DEQ measures air pollution Monitors or samplers are located in areas of the state with a history of, or the potential for, specific air pollution problems. To check current sampling sites in Oregon check our Air Quality Index.
Common air pollutants the Environmental Protection Agency regulates include:National Digital Air Quality Forecast Guidance Page. The starting point for graphical digital government air quality guidance. The Air Management Data Viewer is an interactive map that displays information such as permitted facilities and their emissions, air quality monitoring sites and nonattainment areas in Wisconsin.
This site provides air quality data collected at outdoor monitors across the United States, Puerto Rico, and the U. S. Virgin Islands.
Users can download, output, view or . No current data. Data is presented in Standard Time at the time the measurement ended. An air quality index (AQI) is a number used by government agencies to communicate to the public how polluted the air currently is or how polluted it is forecast to become.
As the AQI increases, an increasingly large percentage of the population is likely to experience increasingly severe adverse health effects. In Canada, air pollution and associated health risks are measured with the Air Quality Health Index or (AQHI).
It is a health protection tool used to make decisions to reduce short-term exposure to air pollution by adjusting .
