One of the most important components of atmospheric aerosols are microorganisms. Therefore, it is necessary to assess the hazard to humans, both from individual microorganisms which are present in atmospheric bioaerosols as well as from their pool. An approach for determining the hazard of bacteria and yeasts found in atmospheric bioaerosols for hu...

Intensive growth of air transport provides increasing in hazardous substances emission in the atmosphere. Among such emissions also are nano-particulates specific with high- surface area and sometimes high non-uniformity resulting in high concentration of radical centers on the surface and therefore in high reactivity and high toxic properties.
