Pediatric ER visits and particulate matter

A study has found that an increase in exposure to particulate matter 2.5 was associated with an increase in pediatric ER visits for a mental health problem days after exposure. The association was stronger between air pollution and emergency room visits for children living in poorer, high poverty neighborhoods. The study used data from 2011-2015 from the Cincinnati Children’s Hospital Medical Center.
