The manufacture, use and disposal of nanomaterials will result in increased human exposures to engineered nanoparticles (ENPs), potentially via the lung. ENPs differ physically and chemically from natural‐ or combustion‐derived nanoparticles (NP) in important respects. While there are parallels with ultrafine aerosol particles in the atmosphere and colloids in water, there remain some unique issues...
Epidemiological studies have generally found fine particle metrics such as PM 2.5 (PM mass less than 2.5μm in aerodynamic diameter) to be more strongly related to adverse health effects than PM metrics that are not size-fractionated, such as total suspended particulate matter (TSP). The latency of long-term PM exposure effects on health could potentially be investigated using the American...
