Air pollution removal through deposition on urban vegetation: The importance of vegetation characteristics

Umweltanalytik: Neue Spurenstoffe in Städten – neue Schadstoffe?

“…6) Beim Prinzip der Luftreinigung durch Vegetation deuten zahlreiche Erkenntnisse auf eine Kombination aus der Makrostruktur grüner Infrastruktur und der Mikrostruktur der Blätter hin: Die Makrostruktur fungiert als poröser Körper und beeinflusst lokale Ausbreitungsmuster von Partikeln; 7) die Mikrostruktur bindet im Idealfall Staub. 8) Begrünte Fassaden sind verstärkt dem Straßenstaub ausgesetzt, der vorrangig aus Verkehr und Industrie stammt. Diese Exposition nutzt das Teceus-Konsortium, um Hinweise auf anthropogene Quellen der TCEs zu finden.…”

Exploring with time-series satellite data of multiple stressors effects on urban/periurban vegetation

“…Is well recognized that urban green spaces have an increased and important role in thermal comfort, through effective mitigating of urban heat island (UHI) effect by canopy shade and evapotranspiration. Urban vegetation, a global terrestrial ecosystem component plays a crucial role for biodiversity and carbon storage, and the reductions of flood risk and air pollutants especially particulate matters and nitrogen dioxide, improving air quality through acting as a protective barrier against pollution dispersal 1,2 . Urban natural environment composed of green and blue spaces is linked to human health improvement and well-being 3,4 .…”

The effect of vegetation in reducing air pollution in an urban environment: A review

“…One of the factors controlling air pollution is the availability of vegetation on roads and in the surrounding environment. The number of motor vehicles that continue to increase with the increase in emissions will also continue to reduce air quality if it is not matched by an increase in the amount of existing vegetation that absorbs pollutants [1], the vegetation in urban areas can improve air quality, moreover in some types of vegetation which have certain characteristics greatly affect the removal of urban pollutants such as particulate matter (PM) and nitrogen dioxide (NO2) from the air [2], Urban greening plays an important role in reducing ambient air pollution and the temperature in areas with greenery will be cooler [3], to identify tolerant plant species that can be useful for pollution removal using tool in air pollution monitoring and in decision making during urban development and urban greening [4], Air pollution that occurs in urban areas will get worse if it is not balanced with optimal air pollution control [5], the number of motor vehicles that continues to increase with the number of emissions that increase will also continue to reduce air quality if it is not matched by an increase in the amount of existing vegetation that absorbs pollutants [6], poor air quality is caused by pollutant loads that enter the atmosphere exceeding their natural dispersion and neutralization capabilities. Several IOP Publishing doi:10.1088/1755-1315/1253/1/012105 2 incidents indicate that the air quality condition is at a moderate and unhealthy level, indicating an excessive load of pollutants entering the atmosphere [7].…”
