So, notably, is 120 format Neopan 400; which was discontinued because it contained perfluorooctanesulfonic acid (PFOS) as a surfactant and anti-static agent. PFOS was added to Annex B of the Stockholm Convention on persistent organic pollutants (POPs) in May 2009: http://chm.pops.int/Convention/Press...S/Default.aspx - Japan has just passed legislation to take up these new controls. Hence Fuji can't continue production of the current formulation. Communication has been poor and Fuji haven't said if there will be a new formulation. PFOS is a powerful immunosuppressant, carcinogen and persists and concentreates in biological systems. I'd have considered avoiding using Neopan 400 120 had I known that the film contained PFOS. PFOS can pass across skin; I am glad I've always worn gloves when processing. It also shows that films are very complex chemically and contain unexpected components. Marty
