摘要

With the advent of nanotechnology, the prospective use of engineered nanomaterials, defined as materials with a diameter below 100 nm, in many applications, due to their advantageous properties, has progressed rapidly. Over the last decade however, there has been increased debate regarding the potential harmful effects of nanomaterials. Predominantly, heightened concern has been expressed regarding the (potential) adverse health effects of nanoparticles (NPs). A plethora of both lab-based and epidemiological studies have previously indicated that inhalation of combustion derived NPs can cause adverse health effects, as well as augment pre-existing diseases, such as chronic obstructive pulmonary disease. Although there are obvious differences between combustion-derived NPs; which are polydispersed and have a chemically complex nature; and engineered NPs; which are in contrast monodispersed with precise chemically engineered characteristics; the same toxicological principles are assumed.
