Glutamatergic Neurons in Rodent Models Respond to Nanoscale Particulate Urban Air Pollutants In Vivo and In Vitro (31 page pdf, Todd E Morgan, David A Davis, Nahoko Iwata, Jeremy A Tanner, David Snyder, Zhi Ning, Winnie Kam, Yu-Tien Hsu, Jeremy W Winkler, Jiu-Chiuan Chen, Nicos A Petasis, Michel Baudry, Constantinos Sioutas, Caleb E Finch, Environmental Health Perspectives, Apr. 7, 2011)

 

Although today’s review article is highly technical and the result of experiments conducted on mice, the implications for the impact of nano-sized vehicle emissions on human brain development is clear. “The evident neurotoxicity of nPM suggests links between urban air pollution and brain health across the lifespan”. Two areas need further study: definition for nano particles within the Ultra Fine Particle (UFP) category of air quality standards and the accumulation of nPM in the brain over time.
