Particulate matter is what researchers call tiny flecks of soot and engine exhaust floating in the air.
A recent report by Selkirk College’s Rural Development Institute (RDI) found that breathing particulate matter can aggravate lung conditions like asthma and bronchitis. The report summarizes other reasearch studies showing that long-term exposure is correlated with increased incidence of heart disease.
