[1] Gennady G., Yoshiharu F., Nikolai K. Are there any toxicology activity in the pollen of cryptomeria japonica (d. don) and some other fruits? // III International Conference DUST 2018 SCIENTIFIC RESEARCH ABSTRACTS. — Vol. 8 of Atmospheric Dust. — Digilabs - Bari, Italy Bari, Italy, 2018. — P. 51–51. Asian dust is a complex mixture of dusts from various sources. Especially negative influence of Asian dust is in cities where are enough negative factors for human health and plant development, such as automobile and industrial exhausts, road dust. Significant contribution to the bioactivity of the Asian dust is extinguished by natural sources of dust - such as massive flowering plants. In this study, the pollen of a number of trees that make a big contribution to the atmospheric dust of Tokyo was studied. Our main interest is in Cryptomeria japonica (D. Don.), because it has the biggest dissemination in Japan, and active producer of high-allergenic pollen. Other trees - Amygdalus persica L., Prunus salicin, Prunus Bretschneider, Prunus avium Japan, Prunus avium China, Malus pumila, Amygdalus persica L., Prunus salicina, Prunus bretschneideri, Prunus armeniaca, Prunus bretschneideri 1 type, Prunus bretschneideri 2 type, Prunus avium are also form massive plantings and produse a lot of pollen. In our pilot study, a possible pollen toxicological effect was determined on the root germination of the model plant Lactuca sativa (sort – Kaiser, Takii seed corporation, Kyoto, Japan). Analysis of the experimental material was carried out using an analytical model derived from conservation laws, mechanics, chemical and biochemical kinetics of reactive living systems using the concepts of continuous medium, similarity theory and dimensional analysis. Particular points of the model found by analyzing the first-, second- and third-order derivatives separate the entire range of pollen exposure to gaps with intrinsic kinetic characteristics. Within the limits of the model it was found that the effect of increasing doses of pollen leads to a regularly increasing positive response of plants, which, after reaching a maximum, is replaced by a regularly increasing negative response, thus, pollen in small doses has a stimulating effect, and in large doses, a depressing effect. The maximum point is the minimum used dose of pollen - 2 mg, or the closest range of values obtained using the analytical model.
