Presentation description

We studied particulate matter (PM) accumulation on six common tree species in Salt Lake City and its relationship to specific leaf traits. Results show that species with needles and evergreen foliage acquired the most PM. Color analysis provided additional insight into the density and type of PM captured by sampled leaves. Our findings are applicable to urban planning, as there is a need to consider diverse and tolerant tree species as part of green infrastructure for air quality mitigation.
