Sacramento, CA – Inhaling engineered nanoparticles, used in consumer products ranging from electronics to cosmetics, can cause lung damage, according to a recent study.

As part of the National Institute of Environmental Health Sciences NanoGo Consortium, researchers from several universities used lab mice and rats to examine the health effects of inhaling two types of nanomaterials. The ultrafine particles were made from titanium dioxide and multi-walled carbon nanotubes, and exposure to both produced signs of lung injury, the study abstract states.

People also may be exposed to nanoparticles during the manufacturing process or commercial application, according to a press release from the UC Davis School of Medicine.

The study was published online May 6 in the journal Environmental Health Perspectives.
