Woody Plants Interaction with Aerosol Fine Particulate Matters and Copper in Budapest

Abstract

Ambient particulate matter pollution is the primary concern as it has a significant impact on human health and the majority of the world's population lives in urban areas. Heavy metals are the most concerning component of particulate matter, and Cu is a highly traffic-related emission element whose overabundance results in toxic effects. Woody plants, on the other hand, contribute to the removal of airborne pollution in urban areas. Our aims are (1) to compare urban woody plants abilities to capture ambient fine particulate matter on leaf surface; and (2) to access the Cu concentration loads on their leaf surfaces. Consequently, our results will provide scientific knowledge for future urban planning concerning air pollution remediation. We investigated the relationship between woody plants and heavy metal pollution in Budapest. Four woody plant species were sampled at different traffic densities. Their Cu contents in the leaf and branch were measured, our results show that Tilia tomentosaAcer platanoidesFraxinus excelsiorAesculus hisppocastanusT. tomentosaA. platanoides
