Soot from heaters and traffic is not just a local problem
aerosol particle soot climate change human health
2021/8/4
Soot particles from oil and wood heating systems as well as road traffic can pollute the air in Europe on a much larger scale than previously assumed. The evaluation of the sources during a measuring ...
Influence of Traffic Flow Patterns on Air Quality inside the Longest Tunnel in Asia
Hsueh-shan Tunnel Air pollutants Traffic flow Piston effect
2016/3/28
The long tunnel is a fixed, semi-closed environment where excessive concentrations of air pollutants are easily
accumulated. This can potentially have a serious affect on drivers' health, especially ...

global tropospheric ozone aircraft road traffic shipping emissions
2010/12/28
In this study, the LMDz-INCA climate-chemistry model and up-to-date global emission inventories are used to investigate the "present" (2000) and future (2050) impacts of transport emissions (road traf...
Influences of Traffic Emissions and Meteorological Conditions on Ambient PM10 and PM2.5 Levels at a Highway Toll Station
PM10 PM2.5 Traffic emission Meteorological condition Highway toll station
2016/3/29
The PM10 and PM2.5 levels at a highway toll station were monitored from October to December 2008. Experimental results
show that hourly average PM10 and PM2.5 levels at the highway toll station were ...

2009/12/31
A method is presented for the evaluation of the exhaust emissions of marine traffic, based on the messages provided by the Automatic Identification System (AIS), which enable the identification and lo...
Atmospheric hydrogen variations and traffic emissions at an urban site in Finland
Atmospheric hydrogen variations traffic emissions Finland
2009/10/9
Atmospheric hydrogen (H2) mixing ratios were observed over a one year period from summer 2007 to 2008 in Helsinki, Finland. Relatively stable background values of hydrogen were occasionally observed a...
MODELING THE SHORT-TERM EFFECT OF TRAFFIC ON AIR POLLUTION IN TORINO WITH GENERALIZED ADDITIVE MODELS
urban area air quality vehicular traffi c CO NO2 NOx NO PM generalized additive models.
2014/6/24
Vehicular traffic typically plays an important role in atmospheric pollution. This is especially true in urban areas, where high pollutant concentrations are often observed. In this paper, we con...
The influence of traffic and wood combustion on the stable isotopic composition of carbon monoxide
traffic and wood combustion stable isotopic composition carbon monoxide
2009/5/15
Carbon monoxide in the atmosphere is originating from various combustion and oxidation processes. Recently, the proportion of CO resulting from the combustion of wood for domestic heating may have inc...
