Exposure to Diesel Exhaust Induces Changes in EEG in Human Volunteers

Apr. 2008- This study examines changes in brain activity, particularly in the frontal cortex, that result from exposure to diesel exhaust (DE), which is a mixture of non-engineered nanoparticles and exhaust compounds.  Further human studies are necessary to determine whether nanoparticles in DE are responsible for these effects and if so, by what mechanism.  

Assessing Toxicity of Fine and Nanoparticles

Sep. 2007- This study indicates that the observed in vitro effects of nanoparticles are not necessarily predictive of in vivo pulmonary effects.  In vitro assays will need to be standardized and validated relative to in vivo effects before they can provide useful screening data on the relative toxicity of inhaled nanoparticles.
