The possibility of establishing a correlation between the mass (or mass concentration) of particles and their number (or number concentration) seems to be interesting. This is a new research task, which due to the lack of clear regulations, has not been performed so far. Published results, e.g. in [5, 7, 8] differ substantially, different because of the different measuring methods and measurement conditions employed. This is associated mainly with the large range of particle diameters, as well as diversified particle number and the mass of a single particle (Table 8.1 and Fig. 8.1). The only constant parameter among the above parameters of particulate matter is particle density; this is accepted, as with establishing the aerodynamic diameter, as 1 g/cm3. This value is the adopted a priori, however it should be noted that it depends on the particle size and decreases with an increase in particle diameter (Fig. 8.2).
