The new European law known as REACH (Registration, Evaluation and Authorisation of Chemicals) was adopted by the Member States and the European Parliament and has entered into force in June 2007. By tabling this new legislation, the European Commission demonstrated its determination to protect Europeans' health and the environment. Indeed, recent scientific research has demonstrated that certain chemicals enter and accumulate in living organisms, including humans. While all substances placed on the market after 1981 have been tested to assess their safety, that is not the case for the tens of thousands of chemicals marketed before that date. That is why the European Union has developed this ambitious new Regulation on chemicals, one of the key sectors of the European economy.
