Levels can be quite variable spatially. 5 has been established from monitoring, but measurements for PM10 and ultrafines are not dense enough to define the distributions and their variability. The United States revised its approach to managing particulate matter when in 1987 it brought in a standard for PM10. A 24 h average of 150 μg/m3 was not to be exceeded more than once per year on average over a three-year period and an annual arithmetic mean, averaged over 3 years was not to exceed 50 μg/m3.
