How does diesel pollution get inside a school bus?
Diesel pollution can enter a school bus from both the tailpipe and the engine. In school buses, the engine is in the front, right near the door, so every time the door opens, engine and tailpipe exhaust get sucked inside. Exhaust can also seep into the bus through open windows and even through the floorboards. Because of this, air quality inside the bus can be five times worse than outside air. Even if your child spends a short amount of time on a school bus, he or she may be breathing in high levels of harmful air pollutants that make up diesel exhaust.
