Every Saturday, 13-year-old Caia Farrell goes running with her classmates. When the group passes a giant, idling truck, they cross the street to get away from the exhaust fumes. But it rarely helps.
“Outside my house right now, there are trucks moving back and forth to various construction sites, spewing pollution, idling on corners and polluting our air,” the Philadelphia-based seventh grader recently told EPA administrators during a public hearing.
That exhaust could be hurting Farrell and her classmates more than scientists previously understood. Researchers increasingly are finding a causal relationship between heavy-duty truck emissions and respiratory ailments such as asthma.
