Emissions Analytics finds pollution from tire wear can be 1,000x worse than exhaust emissions

Green Car Congress

Pollution from tire wear can be 1,000 times worse than a car’s exhaust emissions, Emissions Analytics has found. Source: California Air Resources Board (ARB). New cars now emit very little in the way of particulate matter but there is growing concern around non-exhaust emissions (NEEs). and 73% of PM 10. and 73% of PM 10.

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. Selley et al. It is estimated that only 7% of PM 2.5

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. Tire wear particles pollute the environment, the air we breathe, the water run-off from roads and has compounding effects on waterways and agriculture.

Study finds long-term exposure to black carbon from traffic exhaust at residential address increases the risk of stroke

Green Car Congress

Long-term residential exposure to locally emitted black carbon (BC) from traffic exhaust increases the risk of stroke even in low-pollution environments, according to a study by researchers at Karolinska Institutet and other universities in Sweden. g/m 3 ) of black carbon from traffic exhaust, the risk of stroke increased by 4%.

Team finds high concentrations of combustion- and friction-derived magnetic air pollution nanoparticles in human hearts in Mexico City

Green Car Congress

Solid CFDNPs in air pollution are characterized by the abundant presence of strongly magnetic, iron-rich particles which condense and/or oxidize upon airborne release, often retaining a rounded or spherical shape as they cool. Magnetic CFDNP concentrations and particle numbers ranged from 0.2 annual air quality standard of 12 ?g/m

Study shows two-stroke scooters dominant source of air pollution in many cities; asymmetric polluters

Green Car Congress

A study by European researchers has found that two-stroke (2S) scooters, although constituting a small fraction of the fleet, can dominate urban vehicular pollution through organic aerosol and aromatic emission factors up to thousands of times higher than from other vehicle classes. —Platt et al.

OECD report finds measures needed to curb PM emitted by wear of car parts and road surfaces, including EVs

Green Car Congress

Wear and tear from brakes, tires and road surfaces will soon overtake car exhaust fumes as the leading source of fine particles released into the air by road traffic, according to a new OECD report. Heavy electric vehicles with long-distance batteries could compound the problem even as they slash emissions from engine exhaust.
