Motruk I. Ecological and hygienic assessment of herbaceous plants pollination based on bi-hourly air monitoring in summer and autumn

In this dissertation work, based on complex ecological and hygienic studies, the topical scientific problems of controlling the dynamics of distribution of allergic pollen of herbaceous plants in the atmosphere of the city of Vinnytsia in 2012 - 2014 in bi-hourly mode are solved; the influence of meteorological factors on distribution of pollen is studied and the relationship between the results of skin tests for pollen mixed-allergoid in patients and concentration of pollen of herbaceous flora in the air are established, which allows to improve comprehensively the system of prevention of pollen diseases among the population. Seasonal terms of pollination of herbaceous plants and change in the concentration of their pollen grains during a day have been established, and localization of the source of pollen emission, including outside the city of Vinnytsia, has been determined. It is demonstrated that from May 2012 till October 2014, the most pollen load on patients was observed at 13:00. The change in the characteristics of pollination season of Ambrosia influenced by global warming has been revealed. To improve the ecological and hygienic prognosis, the critical values of meteorological factors have been identified, the exceedance of which results in the increase in the concentration of pollen grains; the "weather factor" cumulative characteristics which combines such meteorological parameters as mean day air temperature, relative humidity and atmospheric pressure that have a significant impact on the pollination of herbaceous flora has been created; critical values of the "weather factor" have been identified, the exceedance of which results in the increase in the concentration of pollen grains in the air and increases the risk of symptoms of ragweed, mugwort and grass pollen allergies. A link between pollination of herbaceous plants and results of skin tests in the population has been proven.
