Ubiquitous engineered nanomaterials cause lung inflammation, study finds
Date:5/6/2013

f everything from carbon to gold. The current study examined the health effects of inhaling two types of nanomaterials, those made from forms of titanium dioxide and those made from multi-walled carbon nanotubes, a substance with a tensile strength 100 times stronger than steel.

The study was conducted as part of the NIEHS NanoGo Consortium, which includes researchers at North Carolina State University, UC Davis, East Carolina University, the Health Effects Laboratory of the National Institute for Occupational Safety and Health, the University of Rochester, the University of Washington and the Center for Environmental Implications of Nanotechnology.

The primary concern for exposure to nanomaterials is by inhalation, although dermal, eye and ingestion exposures also may occur during the manufacture and commercial application of these materials in a wide variety of products. The researchers examined responses of the lungs to nanomaterials made from three forms of titanium dioxide and three forms of multi-walled carbon nanotubes in a mouse model.
