Assessment of environmental impacts based on particulate matter, and chlorophyll content of urban trees Open
Trees improve air quality, and they have irreplaceable aesthetic value in urban landscapes. The amount of dust deposited on tree leaves is a simple and cost-effective indicator of air quality. Our aim was to explore particle filtering capa…
View article: Usefulness of Tree Species as Urban Health Indicators
Usefulness of Tree Species as Urban Health Indicators Open
We used the Air Pollution Tolerance Index (APTI), the amount of PM5 and PM10, and the elemental analysis of leaves to explore the sensitivity of tree species to air pollution. We assessed the tolerance of Robinia pseudoacacia, Acer sacchar…
