Abstract

Aerosol particle volume distribution functions have been used to study the relationships between the total suspended paniculate matter (TSP), PM^ and the "black smoke". We have found that ratios of PMio/TSP are from 0.26 to 0.98 in urban areas. A model describing the dependence of the surface concentration of deposited particles on the darkness index of a stain was developed. Ratios of concentrations measured by the black smoke method to the TSP vary widely. 1 Introduction The total suspended paniculate matter (TSP), black smoke (BS) and paniculate matter less than 10 urn aerodynamic diameter (PMio) have been adopted to describe mass concentrations of airborne particles. Usually, TSP and PMio are measured gravimetrically using various techniques: cyclones, cascade i
