This dossier focuses on workplace safety, industrial law as well as on environmental law (water, air, soil, waste). These fields of law are likewise influenced by EU law and are very complex due to their interlocking with Austrian law. Discussion and conclusion refer to both dossiers on nano-regulation in Austria. They tentatively conclude that current legislation covers in principle nanotechnologies, especially in those cases where nano materials / nano products endanger legal interests. Existing knowledge gaps, the brisk and to some extent unforeseeable development of technologies and their wide range of applications (often across all disciplines and thus across all fields of law) will in some fields lead to specific improvements (sporadically as well to legal reorientation) in order to guarantee an adequate risk and innovation management.
