Table 2.

PM10-2.5 concentrations during exposures (n=32)

Exposure Mean SD Minimum Maximum
Filtered air 10.1 7.1 2.6 27.4
Coarse CAP 76.2* 51.5 10.3 246.5

CAP, concentrated ambient particles; SD, standard deviation

PM10-2.5 concentrations are in µg·m−3 and determined by Teflon filter-based gravimetric mass measurements for the 2-hour period of exposures. Mass levels below the detection limit (6.8 µg·m3) were recorded at this value for analyses (n=15, filtered air exposures only)

*

P values <0.01 for differences of mean or median levels between exposure types
