Background of REACH in EU regulations on evaluation of chemicals

Abstract

Industrial chemicals are needed for chemical synthesis or technical purposes. These beneficial effects are counterbalanced by the potential health risks for all who come into contact with them. The new chemical legislation of the EU, Registration, Evaluation and Authorization of Chemicals (REACH) will force the responsibility of manufacturers and importers of chemical substances to gather the right information needed to decide on the right circumstances of use and control of chemical substances and products. In order to understand the roots of REACH, experiences gained with regard to existing chemicals legislation, particularly in Germany, will be reviewed. Since Council Directive 67/548/EEC all chemicals placed on the market need a set of standard information and provisions for safe transportation. This directive and its amendments (Council Directive(s) 79/831/EEC and 92/32/EEC) have established for new substances a sound information data basis for classification of dangerous properties. Under Council Regulation 793/93/EEC, regulations and administrative provisions have established the requirement to assess the risk to man and the environment of existing substances. So far, only 119 substances have been evaluated under the forces of this regulation. This separation has led to a substantial imbalance between existing substances and new substances with respect to available data needed to recognize hazards for health. The register of produced and imported chemical substances under REACH should eliminate some of this separation and will also be the key for selection of substances of very high concern by the authorization process to restrict the use and distribution accordingly.
