Characteristics of airborne particles and the factors affecting them at bus stations
TLDR
In this paper, the authors investigated the impact of station design and meteorological conditions on particle emissions at the two bus stations of different designs: open station and canyon station, operated according to the same timetables and fleet compositions, as well as at a reference point in Brisbane.About:

Personal exposure to ultrafine particles: The influence of time-activity patterns
TL;DR: The results of experimental analysis aimed at showing the effect of the time-activity patterns on UFP personal exposure are reported, which revealed higher exposure to particle number concentration was higher for women during both summer and winter.

Health effects of daily airborne particle dose in children: direct association between personal dose and respiratory health effects.
TL;DR: In this paper, the authors performed continuous exposure monitoring to estimate alveolar and tracheobronchial dose, measured as deposited surface area, for 103 children and evaluated the long-term effects of exposure to airborne particles through spirometry, skin prick tests and measurement of exhaled nitric oxide (eNO).

Tracheobronchial and alveolar dose of submicrometer particles for different population age groups in Italy
TL;DR: The results showed that the daily alveolar particle number and surface area deposited for all of the age groups considered was equal to 1.7 × 1011 particles and 2.5 × 1015 μm2, respectively, varying slightly for males and females living in Northern or Southern Italy.
Personal exposure to ultrafine particles : the influence of time-activity patterns
TL;DR: In this article, the effect of the time-activity patterns on UFP personal exposure are reported, in particular, 24 non-smoking couples (12 during winter and summer time, respectively), comprised of a man who worked full-time and a woman who was a homemaker, were analyzed using personal particle counter and GPS monitors.

Children exposure assessment to ultrafine particles and black carbon: The role of transport and cooking activities
TL;DR: In this paper, an exposure assessment of children in relation to two different aerosol species: ultrafine particles (UFPs) and black carbon (BC) was performed on 103 children aged 8-11 years using hand-held particle counters and aethalometers.

Respiratory effects are associated with the number of ultrafine particles.
TL;DR: The present study suggests that the size distribution of ambient particles helps to elucidate the properties of ambient aerosols responsible for health effects.

Ambient nano and ultrafine particles from motor vehicle emissions: Characteristics, ambient processing and implications on human exposure
TL;DR: In this paper, the authors reviewed and synthesized the existing knowledge on ultrafine particles in the air with a specific focus on those originating due to vehicles emissions and focused on secondary particle formation in urban environments resulting from semi volatile precursors emitted by the vehicles.

TL;DR: Exposure to exhausts from heavy vehicular traffic may have several adverse effects on respiratory health of children living in metropolitan areas, increasing the occurrence of lower respiratory tract infections early in life and of wheezing and bronchitic symptoms at school age.

Wind tunnel simulation studies on dispersion at urban street canyons and intersections—a review
TL;DR: In this paper, the authors provide a comprehensive review of wind tunnel simulation studies in urban street canyons/intersections including the effects of building configurations, canyon geometries, traffic induced turbulence and variable approaching wind directions on flow fields and exhaust dispersion.
