This data is a summary of the particle info obtained from the SEM using an individual particle analysis method (as described in your handout). Bear in mind that the data on small (lt 3um) particles contains elemental information from the filter on which they collected (mostly C and O). The sample collected in a rural location did not have enough particles to use this analysis method.
