Study finds long-term exposure to air pollution negatively impacts cognitive performance and may become more pronounced with age

Green Car Congress

Researchers from China and the US have found that long-term exposure to air pollution impedes cognitive performance in verbal and math tests. Air quality was measured using the air pollution index (API), which is calculated based on daily readings of sulfur dioxide (SO 2 ), nitrogen dioxide (NO 2 ), and particulate matter smaller than 10 ?m
