Dust of the two Tillandsia species were predominant among dust types found on the honey bees. Examples of B. atratus, B. morio and T. spinipes, found on the blossoms of T. stricta, introduced 100% dust from that plant. Bombus atratus examples visiting T. tenuifolia, introduced 90% dust from that source and 10% from Mimosa pudica, accordingly uncovering the upward scavenging conduct of this honey bee species. Honey bees that visit T. tenuifolia e T. stricta on their blossoming are likely dispersers of their dust.

Bugungi kunda dunyoda sanoat changlari va changli gazlarini tozalashda xo‘l usuldan foydalanish tendensiyasi ortib bormoqda. Ho‘l usul dispers sostavi yuqori (zarra o‘lchami 5 mkm kichik) bo‘lgan zarralarni suyuqlik muhitida ushlab qolishda samarali hisoblanadi.
Among the production of harmful industry all over the world, including in our repub-lic, tobacco production occupies a significant place. In Uzbekistan, tobacco cultivation is car-ried out by workers of the Urgut district of the Samarkand region, which accounts for a large share in agriculture and brings significant economic profit.
The available literature does not cover the issue of the effect of tobacco dust and pes-ticides in combination with uncomfortable microclimatic conditions on the organs and tissues of the oral cavity of tobacco growers.
Some aspects of the mechanism of development of pathological changes in the oral cavity of tobacco growers are not specified in the conditions of Uzbekistan, and accordingly there is no data on adequate methods of their prevention and treatment [1,3]. In this regard, there is a need to study the features of the clinic and the course of the main dental diseases in tobacco growers in order to develop a set of organizational, sanitary, hygienic and therapeutic and preventive measures aimed at improving the quality of the production environment, pre-venting the development and reducing the frequency of dental morbidity among tobacco growers.
Maqolada changli gazlarni ho‘l usulda tozalovchi apparatni sanoatda qo‘llash va uning tozalash samaradorligini aniqlash rejimlari tavsiya etilgan.
