Related QuestionsDoes Asian dust and pollution transport only occur when there is a major dust storm in Asia?
FAQ's on Asian Dust and PollutionNo! This is just when the newspapers like to cover it! The pollution sources in Asia are "on" all the time. There is probably a small amount of pollution that gets transported across the Pacific all the time. The large dust storms only occur when high surface winds are present and when the soil is relatively dry. This usually happens after a frontal passage and is most common in spring. The large dust particles get picked up and the resulting concentrations in Asia can be enormous.
Related QuestionsHow do I know if Asian dust or pollution is present?
FAQ's on Asian Dust and PollutionProbably you won't notice anything. Unless this is a once in 5 year event (10 year, 20 year???). In the April 1998 and April 2001 episodes the large amount of dust produced a strong haziness that was noticed in places that were usually clear. During these events the sun appeared a bit washed out and rather then a bright blue sky, the sky was noticeably whiter. Not like a cloud, but not the beautiful "desert blue" sky either.
Related QuestionsWhat is the relationship between indoor and outdoor air quality (pollution)?
No building is perfectly sealed and so the air inside ultimately originates outside. Air pollution present in the outdoor environment will therefore enter into the building as well. Generally, pollutants present in the outdoor environment are present at a somewhat lower concentration than outside (probably 10 to 90% in most cases). There are several reasons for this. Some pollutants are absorbed by materials in the building. Others deteriorate or react chemically and so disappear.

So then does this mean long- range transport of dust and pollutants is not important?
FAQ's on Asian Dust and PollutionWell, I didn't say that. These pollutants add to local sources. To explain this I can use the EPA's Air Quality Index (AQI). An AQI of 0 represents no pollution (impossible) and for most pollutants an AQI of 100 is the allowable limit where there are demonstrable health effects. So lets say your background air (the air that blows into your region) is normally at an AQI of 20 and your local air pollution adds 70, for a total of 90.

Do the dust or pollution levels ever reach hazardous conditions?
FAQ's on Asian Dust and PollutionFor the people living in Asia, these dust and pollution levels are associated with health impacts. Once these get transported to North America, the levels are much lower. The highest we have seen at ground level is from the 2001 dust event. In this event, PM10 and PM2.5 reached approximately 2/3 of the US air quality standard at several sites along the west coast (see Jaffe, Snow and Cooper 2003 paper in publication list). This is a level associated with health effects for some people.

Related QuestionsWhat is Indoor Air Quality?
Indoor Air Quality (IAQ) refers to the effect, good or bad, of the contents of the air inside a structure, on its occupants. Usually, temperature (too hot or too cold), humidity (too dry or too damp), and air velocity (draftiness or motionlessness) are considered "comfort" rather than indoor air quality issues. Unless they are extreme, they may make someone unhappy, but they won't make a person ill.
Related QuestionsAir Pollution FAQThe air we breathe is made up of a mixture of gases and small particles. Pollutants in the air are chemicals or substances that are harmful to humans, other species, or ecosystems as a whole. These such pollutants can come from human (anthropogenic) sources, or from natural sources such as volcanos or dust storms.
