Nanomaterials vs ambient ultrafine particles: an opportunity to exchange toxicology knowledge

A rich literature exists that has demonstrated adverse human health effects following exposure to ambient air particulate matter (PM), with strong support for an important role for ultrafine (nano-sized) particles. At present, relatively little human health or epidemiology data exists for engineered nanomaterials (NM) despite clear parallels in their physicochemical properties and biological actions in in vitro models.
