What is "skilful" vs. "bad" ozone?
Ozone is a gas equanimous of three atoms of oxygen. Ozone occurs both in the Globe's upper atmosphere and at ground level. Ozone tin exist proficient or bad, depending on where information technology is establish.
Called stratospheric ozone, skillful ozone occurs naturally in the upper atmosphere, where it forms a protective layer that shields us from the sun's harmful ultraviolet rays. This beneficial ozone has been partially destroyed past manmade chemicals, causing what is sometimes called a "pigsty in the ozone." The skilful news is, this hole is diminishing. Learn more than about stratospheric, or "adept" ozone.
Ozone at ground level is a harmful air pollutant, because of its effects on people and the environment, and it is the main ingredient in "smog." Learn more near air emission sources.
How does ground-level ozone form?
Tropospheric, or ground level ozone, is not emitted directly into the air, simply is created by chemical reactions between oxides of nitrogen (NOx) and volatile organic compounds (VOC). This happens when pollutants emitted by cars, power plants, industrial boilers, refineries, chemic plants, and other sources chemically react in the presence of sunlight.
Ozone is most likely to reach unhealthy levels on hot sunny days in urban environments, but can still reach loftier levels during colder months. Ozone can besides be transported long distances past wind, and then even rural areas tin can experience loftier ozone levels.
What are the harmful furnishings of ozone?
What are the health effects of ozone?
Ozone in the air we breathe tin harm our health, especially on hot sunny days when ozone tin reach unhealthy levels.People at greatest risk of harm from breathing air containing ozone include people with asthma. Learn more than about health furnishings.
What are the environmental effects of ozone?
Elevated exposures to ozone tin touch sensitive vegetation and ecosystems, including forests, parks, wildlife refuges and wilderness areas. In item, ozone tin harm sensitive vegetation during the growing season. Learn more than nearly how ozone harms ecosystems.
What are the ozone levels in my community?
Air quality forecasts are often given with weather forecasts on handheld devices, online or in the paper or tv. You lot tin check ozone levels and other daily air quality information by visiting www.airnow.gov and in many areas you tin receive air quality notifications through www.enviroflash.info.
What tin can I do to reduce ozone?
In that location are deportment every 1 of u.s. can accept to reduce air pollution and go on the air cleaner and precautionary measures you can have to protect your health. Visit AIRNow for tips on what you can do.
What is being done to reduce ozone pollution?
How is ozone pollution controlled?
Ozone is ane of the six common air pollutants identified in the Make clean Air Human activity. EPA calls these "criteria air pollutants" because their levels in outdoor air need to exist limited based on health criteria.
There are national ambience air quality standards (NAAQS) for each of the criteria pollutants. These standards apply to the concentration of a pollutant in outdoor air. Acquire more than most criteria air pollutants and NAAQS.
Subsequently working with us and tribes and considering the data from air quality monitors, EPA "designates" an expanse as attainment or nonattainment with national ambient air quality standards. If the air quality in a geographic expanse meets or does ameliorate than the national standard, it is called an attainment area; areas that don't run across the national standard are called nonattainment areas. Acquire more than about ozone air quality designations.
In society to improve air quality, states must typhoon a plan known as a country implementation plan (SIP) to improve the air quality in nonattainment areas. The plan outlines the measures that the state volition accept in order to improve air quality. Once a nonattainment area meets the standards, EPA will designate the surface area as a "maintenance area."
What rules or regulations help reduce ozone pollution?
EPA'due south national and regional rules to reduce emissions of pollutants that form ground level ozone will help state and local governments meet the Agency's national air quality standards. Actions include vehicle and transportation standards, regional haze and visibility rules, and regular reviews of the NAAQS. Learn more nearly ozone standards.
