Study - Canada - Fumes inside school buses hurt kids
Ontario,CAN -CBC News -Nov 21 2005: -- A study of diesel emissions from Ontario school buses raises new concerns about risks to children's health... The Ontario Public Health Association says 10,000 buses across the province need major upgrades. About 800,000 students ride school buses each day in Ontario... The study found that, while the buses are in better shape today than they were 10 years ago, riders are still exposed to levels of exhaust fumes as high as 10 times those found outside, along highways or on city streets... The study's author, Kim Perrotta, says school buses seem to be self-polluting. Emissions from the engine compartment and tailpipe can get into the cabin... She says installing proper filters would cost close to $10,000 a bus, meaning school boards and bus companies face a $90-million to $100-million bill... Perrotta says the government should help pay the bill because the filters would reduce childhood asthma, and the risk that today's children may develop heart and lung disease in the future...
