How does car traffic influence airborne fungal diversity?

Microbial particles including fungi, bacteria, allergens, etc., are common natural components of air. In particular, fungi represent a large portion of the airborne microbes since they are among the most abundant, widely dispersed, and pervasive organisms in the world. Spores of different fungal species dispersed in the atmosphere are considered to be related to air pollution, thus affecting human health. Bioaerosols containing airborne microorganisms and their waste products can cause respiratory disorders and other adverse health effects, such as hypersensitivity pneumonitis and toxic responses.
