A number above 150 is unhealthy for anyone, while anythingbetween 201 and 300 is very unhealthy, according to the US EnvironmentProtection Agency.
Weather conditions in recent days, with dry and cold air anda lack of rain and wind, have been blamed for the poor weather. Theseconditions meant pollution cannot diffuse.
