This review focuses on the observed characteristics of atmospheric new particle formation
(NPF) in different environments of the global troposphere. After a short introduction, we will …

Gasoline direct injection engines are widely used because of their high thermal efficiency,
despite their significant high particulate emissions. Due to the potential carcinogenicity of …

Environmental chambers have been playing a vital role in atmospheric chemistry research
for seven decades. In last decade, oxidation flow reactors (OFR) have emerged as a …

The particulate matter (PM) emissions of gasoline vehicles were much lower than those of
diesel vehicles until the introduction of diesel particulate filters (DPFs) in the early 2000s. At …

Atmospheric nanoparticles can be formed either via nucleation in atmosphere or be directly
emitted to the atmosphere. In urban areas, several combustion sources (engines, biomass …

Particulate black carbon (BC) affects global warming by absorbing the solar radiation, by
affecting cloud formation, and by decreasing ground albedo when deposited to snow or ice …

Road transport significantly contributes to air pollution in cities. Emission regulations have
led to significantly reduced emissions in modern vehicles. Particle emissions are controlled …

Compared to petroleum diesel, renewable diesel fuels and exhaust aftertreatment systems
can reduce primary exhaust emissions that are hazardous to human health and the …

Secondary organic aerosol (SOA) formation from dilute exhaust from 16 gasoline vehicles
was investigated using a potential aerosol mass (PAM) oxidation flow reactor during chassis …

In this study, we present results from 12 years of black carbon (BC) measurements at 14
sites around the Helsinki metropolitan area (HMA) and at one background site outside the …
