In 2011, the European Commission introduced a limit for nonvolatile particle number (PN)
emissions> 23 nm from light-duty (LD) vehicles and the stated intent is to implement similar …

We appraise newly accumulated evidence of the impact of particle pollution on the brain, the
portals of entry, the neural damage mechanisms, and ultimately the neurological and …

Particulate matter (PM), and in particular ultrafine particles, have a negative impact on
human health. The contribution of vehicle PM emissions to air pollution is typically quantified …

ABSTRACT A solid particle number limit was applied to the European legislation for diesel
vehicles in 2011. Extension to gasoline direct injection vehicles raised concerns because …

In the current diesel vehicle exhaust emissions legislation Particle Number (PN) limits for
solid particles> 23 nm are prescribed. The legislation was extended to include Gasoline …

The objective of this study was to compare two methods that are used to separate the solid
and volatile components of an aerosol: the thermal denuder (TD) and catalytic stripper (CS) …

Vehicle exhaust solid particle number emissions> 23 nm (SPN23) and> 10 nm (SPN10)
were studied for 56 market light-duty vehicles with over 1000 laboratory tests. The studied …

Emissions from four heavy-duty and medium-duty diesel vehicles were tested in six different
aftertreatment configurations using a chassis dynamometer. The aftertreatment included four …

Emission inventories are used to quantify sources and identify trends in the emissions of air
pollutants. They use vehicle-specific emission factors that are typically determined in the …

A Particle Measurement Program (PMP) compliant system, an AVL advanced particle
counter (APC) and an alternative volatile particle removal system, a catalytic stripper (CS) …
