Asthma and Air Pollution

Ground-level ozone is part of “smog” or haze. It is most common in cities where there are more cars and use of fossil fuels. It is also more common in the summer when there is more sunlight, heat, and low winds. Ground-level ozone is created by chemical reactions between emissions of burning fuel emissions and volatile organic compounds (VOC), heat, and sunlight. It is associated with worsening respiratory diseases such as asthma and chronic obstructive pulmonary disease (COPD). Ozone triggers asthma because it is very irritating to the lungs and airways.

Nitrogen dioxide (NO2), Sulfur dioxide (SO2), Carbon monoxide (CO), Methane (CH4)

Other gases can also affect your health and environment.

Nitrogen dioxide (NO2) comes from burning fuels. It also forms from emissions from cars, trucks, other vehicles, and power plants. It is part of smog (haze). Breathing in NO2 can cause someone to develop asthma. It can worsen lung disease, especially asthma.3

Sulfur dioxide (SO2) comes from burning fossil fuels, transportation, volcanoes, and industrial processes. It can be found in smog or haze. SO2 can harm plants (including trees). It can harm your lungs and lead to health problems.4

Carbon monoxide (CO) forms from incomplete combustion of fuels and wood. It has no smell. It can be very dangerous when it builds up inside buildings, homes, and cars.

Methane (CH4) is another gas that is part of air pollution. It mostly comes from animal agriculture and in subarctic regions where it is released from melting permafrost. Fossil fuels (oil, gas, coal) and waste (food, landfills, wastewater) also add methane to the air. Methane is 30 times more potent at trapping heat than carbon dioxide (CO2) as a major greenhouse gas that is worsening the climate crisis. Methane can turn into ground-level ozone, which is harmful to human health.5

Pollution Report Paints Gloomy Picture of Smoggiest U.S. Cities

Los Angeles topped the dirty air list for the 14th time in 15 years

By ABC News

April 30, 2014,

More than half of Americans breathe in unhealthy air, according to a new American Lung Association’s “State of the Air 2014” report.

The Association found that air pollution throughout the nation has gotten a little worse since last year’s report. In particular, ozone levels rose in the three year period from 2010 to 2012, possibly because of climate change.

“We’re making progress but some of that could be reversed with rising ozone levels,” said Janice Nolen, the Lung Association’s vice president of national policy. “A changing climate is going to make it harder to protect human health.”

On a good day it can be blue sky...

On a smoggy day it looks like this...
