This timely book examines the evolution and current state of the international regime that prohibits the development, proliferation, and use of chemical and biological weapons. Crowley and Dando concentrate on advances in the study of toxins and bioregulators to demonstrate the relevance of the management of dual-use research in chemical and biological sciences to the effective implementation of the 1975 Biological and Toxin Weapons Convention (BTWC) and 1997 Chemical Weapons Convention (CWC).
