Abstract:
... Allergenic pollens produced by some tree species in urban parks, a part of the urban flora, cause pollinosis, allergic rhinitis, allergic rhinoconjunctivitis, and asthma. The allergenic pollen levels of four urban parks in Aydin (Turkey) were determined using the Index of Urban Green Zones Allergenicity (IUGZA). The potential allergenicity value (PAV) of each species and the crown volume of each i ...
