Review on urban vegetation and particle air pollution – Deposition and dispersion
TL;DR: In this paper, a review revealed that design and choice of urban vegetation is crucial when using vegetation as an ecosystem service for air quality improvements, while low vegetation close to sources can improve air quality by increasing deposition.
Journal ArticleDOI
Biomass burning aerosol emissions from vegetation fires: particle number and mass emission factors and size distributions
TL;DR: In this paper, the authors used published experimental data and different fitting procedures to derive dynamic particle number and mass emission factors related to the fuel type, burning conditions and the mass of dry fuel burned, as well as characteristic CO-referenced emission ratios (PN/CO, PM/CO).
Journal ArticleDOI
Roadside measurements of fine and ultrafine particles at a major road north of Gothenburg
TL;DR: Particle measurements were conducted at a road site 15 km north of the city of Gothenburg for 3 weeks in June 2000 as discussed by the authors. But particle size distribution between 10 and 368 nm was measured continuously by using a differential mobility particle sizer (DMPS).
Journal ArticleDOI
Evolution of the urban aerosol during winter temperature inversion episodes
TL;DR: In this paper, the authors measured the number particle size distributions and compared to other tracers for traffic emissions during winter days with and without morning temperature inversion, and showed that the mixing processes started after the morning inversion and resulted in a relatively well-mixed boundary layer with a height of 1.km around 14:00.

TL;DR: In this paper, a systematic, integrated approach for assessing alternatives for reducing the risks of heat waves, flooding and air pollution in urban settings, with the aim of reducing the risk of maladaptation, is presented.
