Air pollution

Long-term exposure to particulate matter is associated with respiratory and cardiovascular illness. The industrial, commercial and domestic burning of fuel and vehicle engine, brake and tyre wear are the primary sources of particulate matter. Coarse particulate matter or PM10 is less than 10 µm in diameter and concentrations are measured in micrometres per cubic metre of air (µg/m3). PM10 levels exceeded the 50 µg/m3 legal limit 5 times along the A56 in Trafford over the last 12 months.
