The urban areas of Pakistan exhibit some of the world's highest levels of air pollution,
primarily due to sub-2.5 μm particulate emissions. This issue significantly impairs both the …

Background Urban areas are hot spots for human exposure to air pollution, which originates
in large part from traffic. As the urban population continues to grow, a greater number of …

Trees have been reported to help reduce streetside air pollution, hence reduce public
exposure risk to traffic-related air pollutants such as particulate matter (PM). This study …

precursor for the formation of other air pollutants in urban environment such as secondary …

Traffic restriction measures may create safer and healthier places for community members
but may also displace traffic and air pollution to surrounding streets. Effective urban planning …

This study investigated influences of leaf traits on particulate matter (PM) wash-off and (re)
capture (ie, net removal) over time. Leaf samples were taken before and after three rainfall …

The net influence of trees on local air quality in urban street canyons, negative or positive,
has rarely been evaluated by field investigations. To quantify the influence of street trees on …

On-road mobile sources of emissions make important contributions to particulate matter
pollution (PM2. 5–PM10) in cities. The quantification of such pollution is, however, highly …

Epidemiological studies on health effects of air pollution usually estimate exposure at the
residential address. However, ignoring daily mobility patterns may lead to biased exposure …
