Which form finely dispersed organic aerosols. Some products of the oxidation by ozone are phytotoxic. The reaction of β-pinene with ozone in the presence of SO2 leads to the formation of sulfur-containing acidic aerosols. Assuming that terpene emissions close to tree surfaces (needles and bark) are relatively high, a fast reaction with ozone and subsequent oxidation of SO2 to sulfuric acid can be expected. In this way, forest trees actively promote acidic depositions. 66-74 Urban stone is damaged primarily by the process of sulfatation.

In some cases, it would be better to consider the number of aerosol particles that have nucleated. This number depends on the nucleation time (or duration of the experiment), nucleation rate (per unit time and unit area), and the surface area of the pre-existing particle. Denote the initial number concentration of aerosol particles by N0. The number of non-nucleated particles can be obtained by solving the following differential equation. 53) and τ is the duration of the experiment, or nucleation time.
