ICL briefing paper estimates that 52% of all small particle pollution from road transport comes from tires and brakes

Green Car Congress

A new briefing paper from Imperial College London estimates that in 2021, 52% of all small particle pollution from road transport came from tires and brakes. Six million tonnes of tire wear particles (TWP) are released globally each year, and in London alone, 2.6 They are small enough to reach into the deep lung.

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.

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. Our research suggests that we might advise older adults to walk in green spaces, away from built-up areas and pollution from traffic.

Study uncovers role of longer-chain unburned hydrocarbon emissions from diesels in London air pollution; calls for regulatory shift

Green Car Congress

The study found that 60% of the winter primary hydrocarbon hydroxyl radical reactivity in London is from those diesel-related hydrocarbons; the authors predicted that the longer-chain HCs contribute up to 50 % of the ozone production potential in London.

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

Green Car Congress

An open-access paper on their work is published in the journal Environment International While the World Health Organization has not yet set a guideline for safe levels of ultrafine particles, it recognizes that particulate pollution overall is associated with negative impacts on cardiovascular and respiratory health. 2023.107888

Study suggests particulates from brake dust may have same harmful effects on immune cells as diesel exhaust

Green Car Congress

Metal particles from the abrasion of brake pads (brake abrasion dust, BAD) may cause inflammation and reduce the ability of immune cells to kill bacteria, similarly to particles derived from diesel exhaust particles (DEP), according to a new study led by researchers at King’s College London. traffic pollution.
