Nanoparticles in the environment: assessment using the causal diagram approach(11 page pdf, Suchi Smita, Shailendra K Gupta, Alena Bartonova, Maria Dusinska, Arno C Gutleb, Qamar Rahman, Environmental Health, Jun. 28, 2012)
Today we review research into the impacts of naturally occuring (NNPs)and man-made nanoparticles (ENPs)which range from impacts on high level noctiluent clouds (and from this climate warming) to impacts on vegetation and human health. Their very small size (less than 100 nm) poses a potentially greater threat than the particulate matter that has been studied in depth because of their greater reactivity potential and a number of diverse health impacts have been identified ranging from heart and lung diseases to impacts on vital organs, including the brain, via NPs in the bloodstream.
