Ultrafine particles (UFPs; diameter less than 100 nm) are ubiquitous in urban air, and an
acknowledged risk to human health. Globally, the major source for urban outdoor UFP …

Civil aviation is fast-growing (about+ 5% every year), mainly driven by the developing
economies and globalisation. Its impact on the environment is heavily debated, particularly …

A comprehensive assessment of the environmental risks posed by engineered
nanomaterials (ENMs) entering the environment is necessary, due in part to the recent …

Vehicle emissions are identified as a major source of air pollution in metropolitan areas.
Emission control programs in many cities have been implemented as part of larger scale …

This paper investigates urban canopy layers (UCLs) ventilation under neutral atmospheric
condition with the same building area density (λ p= 0.25) and frontal area density (λ f= 0.25) …

Roadside vegetation barriers are used in many urban areas to restrict air and noise pollution
from reaching roadside pedestrians, but their effectiveness in limiting the movement of …

Cyclists are exposed to traffic-related air pollution (TRAP) during their commutes due to their
proximity to vehicular traffic. Two of the main components of TRAP are black carbon (BC) …

Building activities generate coarse (PM 10≤ 10 μm), fine (PM 2.5≤ 2.5 μm) and ultrafine
particles (< 100 nm) making it necessary to understand both the exposure levels of …

Signalised traffic intersections (TIs) are considered as pollution hot-spots in urban areas, but
the knowledge of fundamental drivers governing emission, dispersion and exposure to …

Four measurement campaigns were performed in two different environments–inside the
harbour areas in the city centre of Helsinki, and along the narrow shipping channel near the …
