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. The distribution of health impacts and air pollution from transportation is influenced by policy, demographic, economic, and technological changes.

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.

the criteria pollutants and CO 2 that emerge with the exhaust from the tailpipe. However, there is more than 15 years of research showing that the contribution of non-exhaust primary particles to the total traffic generated primary particles is significant in urban areas. Further, a 2013 review by Denier van der Gon et al.

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. No data was available to compare trends in ΔPM 2.5 between the two periods.

California ARB releases three studies showing fine particle pollution a threat to cardiovascular health

Green Car Congress

ARB regulates two size classes of particles: up to 10 microns (PM 10 ) and up to 2.5 or fine-particulate matter, is exhaust from vehicles, especially from diesel engines. We’ve long known particulate matter is a major component of California’s air pollution problem. microns in size (PM 2.5 ). particles are a subset of PM 10.

New mixed-oxide catalysts shown as viable substitute for platinum catalysts for diesel exhaust aftertreatment

Green Car Congress

Under laboratory-simulated diesel exhaust conditions, this mixed-phase oxide material was superior to Pt in terms of cost, thermal durability, and catalytic activity for NO oxidation. Mullite is not only easier to produce than platinum, but also better at reducing pollution in diesel engines. Kyeongjae Cho.

Rice University study of lung cells suggests anthropogenic carbon nanotubes are common pollutants

Green Car Congress

These nanostructures are similar to those present in dusts and vehicle exhausts collected in Paris, as well as to those previously observed in ambient air in the USA, in spider webs in India, and in ice cores, the researchers found. Carbon nanotubes and carbon nanoparticles (a) in vehicle exhaust and (b) inside a lung cell vacuole.
