Study links exposure to diesel exhaust particles to pneumococcal disease susceptibility

Green Car Congress

Researchers from the University of Liverpool, Queen Mary University, London and Trinity College Dublin have linked exposure to diesel exhaust particles (DEPs) to susceptibility to pneumococcal disease. What we did not know however, was how pollution, such as diesel exhaust particles, actually causes airway disease.

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.

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.

Study links ambient PM2.5 and ozone specifically caused by vehicle exhaust emissions to ~361,000 premature deaths worldwide in 2010 and ~385,000 in 2015

Green Car Congress

Exhaust from on-road diesel vehicles was responsible for nearly half of the impacts (~181,000 premature deaths) worldwide, and fully two-thirds in India, France, Germany, and Italy. —Susan Anenberg, lead author of the study and an associate professor at the George Washington University Milken Institute School of Public Health.

Two new studies of road air pollution in London find detrimental effects on over-60s and unborn babies

Green Car Congress

Exposure to air pollution on city streets is enough to counter the beneficial health effects of exercise in adults over 60, according to new research led by Imperial College London and Duke University. Environmental measurements were also collected, to track pollution levels and volunteers’ exposure.

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

Green Car Congress

A study by researchers at the University of Birmingham in the UK has found that while Diesel Oxidation Catalysts (DOCs) and Diesel Particle Filters (DPFs) has been very effective in controlling the tailpipe emissions of solid particles, there has been little change in the liquid mode ( 104 cm −3 /24-hour mean) defined by WHO.

Surrey study investigates effect of group cycling on exposure to pollutants

Green Car Congress

In an open access paper in the Journal of Wind Engineering and Industrial Aerodynamics , researchers at the University of Surrey (UK) have investigated the effect of group riding on cyclists’ exposure to vehicle pollutants. —Schmeer et al. With more wind, riding towards the back of the group can be a good strategy to minimize exposure.
