Most Americans have heard of air pollution, but might not think the issue affects them, especially if they live in quiet, suburban areas. Despite this feeling of safety, a new study conducting by members of the California Environmental Protection Agency found air pollution can strike anywhere, according to the Los Angeles Times.
According to the report, scientists used an environmental health screen tool called CalEnviroScreen to evaluate how polluted certain areas of Southern California were. The collected data found the three highest air polluted town were all in the San Joaquin Valley, specifically, Fresno, Bakersfield and Stockton.
"Some people expected most of these ZIP codes to be in industrial, urban areas," Sam Delson, a spokesman for California's Environmental Protection Agency, told the news outlet. "It was surprising to some that while many were in urban areas, a lot of them were in agricultural areas."
The Clean Air Act reports the U.S. deals with six major air pollutants: carbon monoxide, ground-level ozone, lead, nitrogen dioxide, particulate matter and sulfur dioxide, though there are many secondary issues as well.
Families interested in keeping air pollution out of their homes can invest in medical-grade air purifiers like the IQAir GC MultiGas to breathe easy indoors.
