THE YALE JOURNAL OF BIOLOGY AND MEDICINE 50 (1977) Removal of Atmospheric Particulates by Urban Vegetation: Implications for Human and Vegetative Health
A review of the literature reveals considerable evidence to support the suggestion that vegetative surfaces remove particulate matter from the atmosphere. Preliminary observations of the leaf surfaces of an important urban tree indicate the presence of numerous particulate contaminants. In view of t...
