If most of the increase in mortality is expected to be associated with the fine fraction of PM10, then it is reasonable to assume that the same proportional increase in risk would be observed if a distributed lag model were applied to the PM2.
Distributed lag models of the PM2 usually correlate to the mortality associated with PM10.
