The United States has an extensive air quality problem and it’s getting worse, according to a report from the National Highway Traffic Safety Administration (NHTSA).
The agency issued a list of air quality indicators in May to help people assess whether their vehicle is being affected by the problem.
The list includes “air quality indices,” or indicators that are not weather related but could indicate a problem.
Here are some of the more common ones: NHTS says it expects a significant increase in carbon monoxide levels from diesel-fueled vehicles, with an increase in emissions that are in the 5 percent to 15 percent range.
The report said that a small increase in nitrogen oxides is expected from new cars.
More importantly, the NHTSA says it sees “an increase in the amount of particulate matter in the air that is expected to be significant for the coming months.”
The agency said that the increase in particulate particulates is expected, but there is not yet any evidence of a link between the air quality and an increase.
“The increase in pollution will have a major impact on the quality of life in communities where pollution exists,” the agency said in a press release.
“The National Ambient Air Quality Index (NAQI) is a useful tool that can be used to determine whether your vehicle is operating at an unhealthy level.
However, a small decrease in air quality is not necessarily a cause for concern, and in fact could actually improve the air you breathe.”
In the U.S., particulate pollution is considered a pollutant that can cause breathing problems, particularly for people who have asthma.
