High Ozone Days
Ozone air pollution, sometimes known as smog, is one of the most widespread pollutants in the United States. It is a powerful lung irritant. When inhaled into the lungs, it reacts with the delicate lining of the airways, causing inflammation and other damage that can impact multiple body systems. Ozone exposure can also shorten lives.
Particle Pollution - 24 Hour
Particle pollution is a deadly and growing threat to public health in communities around the country. The more researchers learn about the health effects of particle pollution, the more dangerous it is recognized to be. Short-term spikes in particle pollution that last from a few hours to a few days can kill. Most premature deaths are from respiratory and cardiovascular causes. Spikes in particle pollution also have many other harmful effects, ranging from decreased lung function to heart attacks.
Particle Pollution - Annual
Particle pollution is a deadly and growing threat to public health in communities around the country. The more researchers learn about the health effects of particle pollution, the more dangerous it is recognized to be. Breathing particle pollution day in and day out can be deadly. Research has also linked year-round exposure to particle pollution to a wide array of serious health effects at every stage of life.
Populations At Risk
All of the millions of Americans living in places with failing grades for unhealthy levels of ozone or particle pollution are at risk of harm to their health. But some groups of people are especially vulnerable to illness and death from their exposure.
What do INC and DNC Mean?
INC (Incomplete) indicates that some monitoring data was collected for at least one year in the county, but not all three years.
DNC (Data Not Collected) indicates that data on that particular pollutant is not collected in the county.
