Diesel exhaust from school buses, trucks, generators, and other traffic sources contains harmful pollutants that can affect respiratory health and increase long-term health risks. Children are especially vulnerable because their lungs and other organs are still developing, while families who live, play, or attend school near major roads and trucking corridors may face greater exposure.
These Pennsylvania-specific resources explain how diesel pollution affects children and communities across the state, including the elevated risks associated with diesel soot in many Pennsylvania counties. They also provide practical steps for parents, schools, health professionals, and advocates to reduce exposure, improve air quality around schools, support cleaner school buses, and advance healthier transportation policies.
