The European Union’s Scientific Committee on Emerging and Newly Identified Health Risks conducted studies on the risks and hazards associated with nanotechnologies and found significant gaps in understanding of the hazards associated with such products. The reports highlighted the fact that an understanding of the physiological response to nanoparticles and the dose-response relationships for such responses is lacking. Our focus in this area has been the quantification of particle size distribution of nanoparticles, and the use of biochemical (enzyme assays) and biological (cell culture) models for quantification of nanoparticulate toxicity.
Fire Toxicity Assessment – Death in fire may be caused either by gases which are directly toxic or which cause such irritation that they impair vision and breathing, preventing escape, or by smoke which not only impairs escape ability by visual obscuration, but also contains particulate matter which is sufficiently small to pose a respiratory hazard. Combustion toxicity is highly dependent on fire conditions. It depends on material, ventilation condition, oxygen depletion and fuel geometry.
