Researchers show mechanism by which diesel exhaust particles trigger respiratory “flare-ups”

Green Car Congress

Researchers at Imperial College London, working with colleagues from King’s College London and University of British Columbia, have demonstrated a mechanism by which diesel exhaust particles directly affect the lungs to initiate symptoms such as a tightening of the airways and cough.

HEI launches two new non-tailpipe particulate emission studies

Green Car Congress

Emissions from automobile exhaust systems have decreased in recent years due to the introduction of cleaner fuels and new control technologies on internal combustion engines, as well as increases in numbers of hybrid and electric vehicles. and PM 10 , including of NTP and TP emissions, at key selected London trial sites.

KCL study finds London air pollution from traffic improving, but continues to exceed limits in many parts of city

Green Car Congress

New research by scientists at King’s College London suggests that air pollution from London’s roads is improving overall but more work may be needed to tackle some sources of traffic pollution, which continue to breach limits in many parts of the city. Despite a reduction in the total number of vehicles on London roads by 0.5%

US study of miners links heavy exposure to diesel exhaust to increased risk of lung cancer death; researchers suggest implications for urban areas with high exhaust concentrations

Green Car Congress

In a study of non-metal miners in the US, federal government scientists report that heavy exposure to diesel exhaust increased risk of death from lung cancer. For never-smokers, risk of lung cancer death increased with increasing diesel exhaust exposure. effect of diesel exhaust exposure on lung cancer mortality in.

Study shows that urban cyclists have higher levels of black carbon in lungs than pedestrians

Green Car Congress

Cyclists in London and other major cities have higher levels of black carbon in their airway cells, according to research presented at the European Respiratory Society’s Annual Congress in Amsterdam. The results suggests that cyclists inhale more black carbon than pedestrians, which may cause damage to the lungs.

U Birmingham study finds DPFs have limited impact on ultrafine particle emissions

Green Car Congress

—Professor Roy Harrison, corresponding author The team used data collected in from a monitoring station in Marylebone Road, in London. Black carbon, for example, declined by 81% between 2014 and 2021. This is a clear indication that there has been a positive impact from the introduction of exhaust filters.
