Particulate
Matter of fewer than 10 microns diameter is referred to as PM10. Typically
this will include dust, dirt, smoke, soot and liquid droplets, deposited
into the atmosphere by industry and transport. They can also be formed
through condensation of pollutants such as nitrogen oxide.
PM10s
are well known to a major danger to human health, as long-term exposure
has serious effects on respiration. They cause damage to lung tissue
and are thought to cause cancer. However, the reason why they do this
is not fully understood. Asthmatics are the primary victims of particulate
pollution, due to inflammation of the lungs.
PM10
pollution can be highly dependant on weather patterns, with high concentration
occurring on warmer, less windy days. This prevents the particulate
matter from being dispersed, and particulate pollution can build up
near busy roads. The concentration of particulates is expected to decrease
somewhat in the next ten years, as EU regulations for vehicle emissions
come into force. However, the overall levels of particulate pollution
are difficult to predict, as wind patterns may blow PM10 pollution from
Eastern Europe into the country.
Particulate
matter in the home can be generated through many types of improperly
ventilated household appliances.
