PHOENIX – Oslin Lopez is not like most 10-year-olds. She’s not allowed to play outside, ride her bike, let alone run. Her mother keeps her indoors, away from the polluted air in their neighborhood near 27th Avenue and Van Buren Street, which worsens Oslin’s asthma symptoms.
One outdoor activity the girl can’t dodge, though, is riding a diesel-powered school bus to and from Cesar Chavez Elementary School, something her mother, Herlinda Calderon, said has complicated her respiratory condition and overall health.
