The Influence of Phytoaerosoles on Man The substantial aim of the paper was to present the effects of the volatile substances, called phytoaerosoles, isolated by higher-rank plants into atmosphere and soil, on a human organism. On the basis of the data taken from literature successively have been discussed: the division of phytoaerosoles according to probable physiological characteristics, the influence of phytoaerosoles on a human body particularly con sidering the effeect of forest microclimate. This type of microclimate is dependent on four factors such as: landscape, weather, allergy and aero- chemistry.
