International audienceNon engineered nanoparticles (NP), also called ultrafine particles (∅ < 100 nm), have numerous sources in the atmosphere as well as indoors (e.g. traffic, cooking...). To date studies on NP levels in ambient and indoor air are scarce. The NANOP project aims at assessing nanoparticle levels and their spatial and temporal variation in a domestic environment. The study is carried out in an experimental and fully controlled house
