the chemicals without in any way changing the definitions and the five categories already agreed upon. Such a regrouping also opens the way for a comprehensive way of dealing with the chemicals, so that one and the same chemical would be subject to the same regime in all parts of the Convention (i.e. as regards declarations, elimination, permitted production and verification). The philosophy of the approach is simple. Based on existing definitions the chemicals are arranged in three groups. To each group a regime for the declarations, elimination, production and verification is devised. Regime I is the most stringent and demanding one and applies to all Group I-chemicals. Regime II is also stringent but somewhat less burdensome and applies to all the Group II-chemicals. Regime III is the least stringent of the three and applies to the Group Ill-chemicals . GE.85-65876 CD/632 page 2 The three Groups and some main elements in their respective Regimes are described below. The main purpose of this paper is to outline the basic approach, not to suggest solutions for each and every detailed problem. The arrangement of the chemicals into groups is made irrespective of which procedures will eventually be agreed upon for establishing lists or otherwise identifying individual chemicals within the categories. Furthermore, this working paper deals only with chemicals and the means of their production. Munitions and other devices are not covered. It is understood, however, that declarations and elimination of existing munitions and other devices should follow Regime I when applicable. GROUP I CHEMICALS - REGIME I Group I Chemicals 1. Super-toxic lethal chemicals developed, produced or stockpiled for chemical weapons purposes. Examples: Tabun, Soman, Sarin, VX. 2. Super-toxic lethal chemicals which are found to be presumptive chemical weapons. Examples: Amiton, skin penetrating carbamates. 3. Other lethal and harmful chemicals developed, produced or stockpiled only for chemical weapons purposes: Examples: Adamsite, BZ.
**Analysis**
The text appears to be discussing the classification and regulation of chemicals, focusing on their toxicity and potential use as chemical weapons. The language used is formal and technical, suggesting that the text is related to international agreements and treaties. The categories mentioned in the text, such as "Group I Chemicals" and "Regime I", imply a framework for controlling and eliminating certain chemicals. This framework is likely to be part of a broader international agreement or treaty.
