We conducted a factor analysis on the daily concentrations of the chemical components of [PM.sub.2.5] from samples collected by the DFPSS (Al, Si, S Ca, Fe, Zn, Mn, Pb, Br, [K.sub.S], OC, and EC).
[PM.sub.2.5] (obtained from the DFPSS) was highly correlated with CO (r = 0.85) and [NO.sub.2] (r = 0.79), but less so with [SO.sub.2] (r =0.43).
One possible explanation for this observation is related to the fact that the [PM.sub.2.5] cyclone on the DFPSS was replaced with a WINS on 20 December 1996.
