UK expert group focuses attention on non-exhaust emissions from road traffic as regulatory concern

Green Car Congress

A new report released by the Air Quality Expert Group ( AQEG ) in the UK recommends as an immediate priority that non-exhaust emissions (NEE) are recognized as a source of ambient concentrations of airborne PM, even for vehicles with zero exhaust emissions of particles. and PM 10 emissions. of all UK primary PM 2.5

Chalmers study finds ship exhaust gas scrubbers responsible for up to 9% of certain hazardous emissions into Baltic Sea

Green Car Congress

New research from Chalmers University of Technology, Sweden, finds that the discharge water from ships’ exhaust gas treatment systems—i.e., scrubbers—is responsible for up to 9% of certain emissions of carcinogenic and environmentally harmful substances in the Baltic Sea—considerably more than was previously known.

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. It is estimated that only 7% of PM 2.5
