Studies into the effects of ultrafine particles in the lung have shown adverse effects
considered to be due in part to the particle size. Air pollution particles (PM10) are associated …

Abstract Introduction and Objectives: Recent epidemiological studies have shown an
association between increased particulate urban air pollution and adverse health effects on …

PM 10 contains an ultrafine component, which is generally derived from combustion
processes. This ultrafine fraction may be a factor in the increases in exacerbations of …

Experimental studies have shown that rats exposed to ultrafine particles of, for example,
titanium dioxide or carbon black, sustain more lung injury and pathology than rats exposed …

PM10 is a complex mixture of particles and we have focused here on the ultrafine
component, ie particles with a diameter of less than 100 nm. In PM10 this fraction is mostly …

Background: Ultrafine particles have been hypothesised to be an important contributing
factor in the toxicity and adverse health effects of particulate air pollution (PM10) and …

Increased levels of particulate air pollution are associated with increased respiratory and
cardiovascular mortality and morbidity. Some epidemiologic and toxicologic research …

Ultrafine particles (less than 100 nm in diameter) are encountered in ambient air and at the
workplace. Normal background levels in the urban atmosphere for ultrafine particles are in …

Epidemiological studies continue to indicate associations between exposure to increased
concentrations of ambient fine and ultrafine particles and adverse health effects in …

Objective: Rats exposed to high airborne mass concentrations of low-solubility low-toxicity
particles (LSLTP) have been reported to develop lung disease such as fibrosis and lung …
