Abstract

This study explores the following question: how do different green roof vegetation species contribute to particulate matter deposition relative to a white roof in Portland, Oregon? To answer this question, rinse water from two species of vegetation and rinse water from a white roof were filtered to measure the mass of particles found on these leaves. Leaf area was then determined in order to calculate the density of particles found on each surface. The resulting conclusions from this process clearly indicate that a larger density of particles collected on vegetative surfaces as opposed to the surface of the white roof. The density of specific metals present on each surface was also determined and compared. This analysis resulted in the conclusion that although S. kamchaticum contained a higher density of particles, the white roof may be more effective at collecting particular harmful metals.
