Kids in three of Rhode Island's five counties are breathing unhealthy air, according to a recent report evaluating ground-level smog and particulate pollution.
The American Lung Association said in its 2026 “State of the Air” report that nearly half of U.S. children — about 33.5 million — are breathing unhealthy levels of air pollution, with 152 million people overall living in areas that received failing grades for smog (ozone) or particle pollution.
The report, based on 2022–2024 data, evaluates counties for ground-level ozone (smog) and both short- and long-term particle pollution, ranking the cleanest and most polluted areas nationwide.

Children are particularly vulnerable because their lungs are still developing.
Exposure to unsafe air is linked to asthma, reduced lung growth, cognitive disorders, and an increased risk of disease later in life. Pollution has also been linked to heart attacks, strokes, premature death, and lung cancer.
