Nanomaterials can have different or new properties in comparison with conventional chemicals and materials. Meanwhile the substance legislations was partially adapted by nano-specific provisions; for parts however adaptation needs still exist. As a result, specific environmental risks cannot be fully described and assessed as well as appropriate measures to minimize the risks cannot be taken. Emphasis of this paper is to outline the adopted as well as necessary further development of chemicals regulations for nanomaterials with regard to the environment from UBA´s perspective.
