The Organization for the Prohibition of Chemical Weapons is responsible for implementing the Chemical Weapons Convention, which bans the use of chemical weapons and requires their elimination. The United States and other member states have raised concerns that a number of management weaknesses may prevent the organization from fulfilling its mandate. As requested, GAO assessed the accuracy of the organizations budgets and the impact of budget shortfalls on program activities. GAO also reviewed efforts to improve the organizations budget planning.

During the next 10 years, the Environmental Protection Agency may consider asmany as 70,000 chemicals for potential risk to humans and the aquatic environment. As many as 14 kinetic and equilibrium constants can be required for predicting the fate and transport of each chemical, and relatively few reliable constants are available in the literature. Laboratory measurement of the needed constants is prohibitively expensive (as much as $7 billion for all constants and chemicals combined) and too slow for rapid response to site-specific evaluations.

At the request of the Department of Energy, the Bureau of Mines has investigated the hazards of military explosives dispersed as dust clouds in a 20-L test chamber. In this report, the effect of particle size for HMX, HNS, RDX, TATB, and TNT explosives dusts is studied in detail. The explosibility data for these dusts are also compared to those for pure fuel dusts. The data show that all of the sizes of the explosives dusts that were studied were capable of sustaining explosions as dust clouds dispersed in air. The finest sizes (<10 (mu)m) of explosives dusts were less reactive than the intermediate sizes (20 to 60 (mu)m); this is opposite to the particle size effect observed previously for the pure fuel dusts. At the largest sizes studied, the explosives dusts become somewhat less reactive as dispersed dust clouds. The six sizes of the HMX dust were also studied as dust clouds dispersed in nitrogen.
