NANOaers Project Logo

The German Federal Institute for Risk Assessment (BfR) is coordinating the new ERA-Net SIINN research project "NANOaers" which is examining airborne particle mixtures and their possible effects on health.

 

Despite the constant increase in the use of industrially manufactured nanomaterials (NM), little is known about their fate after being released into the air and ingested into the body through inhalation. A further question is, if nanomaterials may cause adverse health effects in the bronchial tract and in the alveolae in the lungs. The purpose of the international research project NANOaers (= Fate of aerosolised nanoparticles: The influence of surface active substances on lung deposition and respiratory effects) is to establish where airborne, respirable particles remain after they have been inhaled. The project is being funded in Germany by the Federal Ministry of Education and Research (BMBF).

"We are also particularly interested here in the question of possible co-exposure to particles and other substances contained in aerosols," explains the president of the Federal Institute for Risk Assessment (BfR) Professor Dr. Dr. Andreas Hensel, "because nanoparticles in the air don't exist in their pristine form. They are subject to change processes when released and are usually inhaled as a mixture along with other particles and substances". This aspect is of significance, as humans and the environment are only seldom exposed to or contaminated with nanomaterials which have not already been altered by chemical substances either by their use per se or through reactions in the atmosphere. In addition to the EU countries Germany, Austria, Spain and Romania, the USA is also participating in this international research project, which is being funded to run for three years within the ERA-NET SIINN framework. The project has a total volume of approx. 1.7 million euros.
