GESTIS – International limit values for chemical agents
This database contains a collection of occupational limit values for hazardous substances gathered from various EU member states, Canada (Québec), Japan, Switzerland, Singapore, and the United States as of August 2011.
Limit values of more than 1,300 substances are listed. Limit values defined by the various expert bodies and authorities differ in the criteria for their derivation, the level of protection which they offer, and their legal relevance.
The short-time values and dust fractions may for example be based upon different definitions. Comprehensive explanations can be found in the original lists of limit values, which should be referred to as primary sources. The purpose of this database is merely to provide an overview of the limit values in various countries.
