Journal ArticleDOI
On-road and laboratory evaluation of combustion aerosols-Part1: Summary of diesel engine results
TL;DR: In this paper, on-road emissions from four, heavy-duty diesel truck engines were measured and the same engines were reevaluated in the manufacturers' laboratories, showing that nuclei mode particles consisted mainly of heavy hydrocarbons.

TL;DR: A review of vehicle exhaust particulate emission measurements can be found in this article, where the focus is on current and newly evolving instrumentation, including gravimetric filter measurement, chemical analysis of filters, light extinction, scattering and absorption instruments, and instruments based on the electrical detection of exhaust aerosols.
Journal ArticleDOI
The effective density and fractal dimension of particles emitted from a light-duty diesel vehicle with a diesel oxidation catalyst
TL;DR: In this paper, a differential mobility analyzer (DMA) and a Couette CPMA were used to measure the effective density and fractal dimension of particles emitted from a light-duty diesel vehicle fitted with a diesel oxidation catalyst (DOC), which was found that at high engine loads, the DOC increased in temperature, sulphate levels in the particulate matter increased, and a transient nucleation mode was observed.

A New Electrical Mobility Particle Sizer Spectrometer for Engine Exhaust Particle Measurements
Journal ArticleDOI
Diesel soot mass calculation in real-time with a differential mobility spectrometer
TL;DR: In this paper, a Bayesian statistical algorithm for parametrising spectral data from the Cambustion DMS500 in terms of a number of lognormal functions is outlined, allowing the nucleation and accumulation modes of a Diesel aerosol to be treated separately and also to reduce mass calculation noise and improve spectral resolution.

TL;DR: It is concluded that inhaled 99mTc-labeled ultrafine carbon particles pass rapidly into the systemic circulation, and this process could account for the well-established, but poorly understood, extrapulmonary effects of air pollution.
Journal ArticleDOI
Ultrafine (nanometre) particle mediated lung injury
TL;DR: In this paper, a sequence of events following pulmonary deposition of ultrafine particles can be hypothesised, based on studies to date, which can be seen as an important factor in stimulating inflammation and interstitial transfer.
Journal ArticleDOI
Pulmonary Retention of Ultrafine and Fine Particles in Rats
TL;DR: Both acute instillation and subchronic inhalation studies showed that ultrafine particles at equivalent masses access the pulmonary interstitium to a larger extent than fine particles (integral of 250 nm).
Journal ArticleDOI
Unipolar and bipolar diffusion charging of ultrafine aerosol particles
TL;DR: In this article, the authors investigated unipolar and bipolar diffusion charging of monodisperse aerosol particles of 4-100 nm in diameter and found that the ratio of positively to negatively charged particles is approximately 0.35:0.65, which is explained by the difference in physical properties between positive and negative ions.

Free radical activity associated with the surface of particles: a unifying factor in determining biological activity?
TL;DR: Using a sensitive phi X174 RF plasmid DNA assay, free radical activity was detected at the surface of normal and ultrafine titanium dioxide (TiO2), environmental particles (PM-10), asbestos and a range of man-made fibres.
