The research was conducted to determine the concentration of plant pollen and fungal spores in Karakol in 2017. The article proposes a method of capturing aerobiological particles by volumetric method using «Lanzoni s.r.l.» apparatus. It is determined that in the air of Karakol pollen of 28 plant taxa (15 taxa of tree and shrub plants, 13 taxa of grasses), 24 taxa of fungal spores circulate. The aeropalynological spectrum was dominated by wormwood, cereals, hemp, madder, pine, cypress, birch and poplar. In the aeromycological spectrum of 2017 the leading fungal spores were сladosporium, fusarium, alternaria, ustilago, sorosporium and aureobasidium.
