Aparticulate matter sampler was operated for 24 hours at a flowrate of 1.4 m3 min-1. the starting weight of the filter paper before sampling was 2.05 grams. at the end of the sampling period, the filter's weight was 3.84 grams, and the gain in weight was due completely to the particulate matter that had collected on the surface of the filter paper during air sampling. determine the particulate matter concentration, in micrograms per cubic meter (expressed to one decimal place), for the given sampling time.
