Airborne Nanoparticles cause respiratory and cardio problems Prof. Richard Flagan, California Institute of Technology 2011
"Airborne nanoparticles have been measured for more than a century, but their chemical and physical nature is only now beginning to be understood. Exposures to nanoparticles (particles with diameters smaller than 100 nm) have been linked to a number of adverse respiratory and cardiovascular health effects. Once thought to be rare, the formation of nanoparticles by homogeneous nucleation of the products of atmospheric photochemical reactions has now been observed in both pristine remote locations, and in polluted urban environments. The key to this growing understanding of these small particle is instrumentation that enables rapid measurement of particle size distributions in the low nanometer size range using the scanning electrical mobility spectrometer (also known as the scanning mobility particle size, SMPS). Originally limited to particles larger than about 10 nm, recent advances have enabled measurements down to 1 nm diameter, and made possible measurements of incipient particles. Using these tools, we are probing the formation of particles in atmospheric reactions, and examining the role of atmospheric ions in the nucleation process. To enable rigorous study of the health impacts of airborne nanoparticles, we have developed new instrumental approaches that make it possible to miniaturize instruments for nanoparticle measurement and to develop personal nanoparticle exposure monitors." https://ias.hkust.edu.hk/events/airborne-nanoparticles California Institute of Nanotechnology, right.

Most doctors can and will act coy over nanoparticle exposure. 🙁 "If this pollutant exposure is repeated, it leads to emphysema-like injuries in the alveoli, caused by the death of individual lung epithelial cells - which in turn is one of the main reasons for incurable chronic lung diseases such as COPD." https://www.helmholtz-munich.de/.../air-pollution-and...
