The increasing use of nanomaterials in consumer goods such as paint, building materials, and food products has increased the likelihood of human exposure. Inhalation is one of the most prominent routes by which exposure can occur, and because inhalation of nanomaterials may be linked to lung problems such as pulmonary fibrosis, testing is conducted to assess the safety of these materials.
The review is one part of the proceedings of a 2015 workshop organized by the PETA International Science Consortium, at which scientists discussed recommendations for designing an in vitro approach to assessing the toxicity of nanomaterials in the human lung.
The expert recommendations proposed at the workshop are currently being used to develop an in vitro system to predict the development of lung fibrosis in humans, which is being funded by the Science Consortium.
"International experts who took part in last year's workshop have advanced the understanding and application of non-animal methods of studying nanomaterial effects in the lung," says Dr. Monita Sharma, nanotoxicology specialist at the Consortium and lead author of the review in Archives of Toxicology. "Good science is leading the way toward more humane testing of nanomaterials, which, in turn, will lead to better protection of human health."
