摘要：The number of new chemicals synthesized and marketed increases exponentially. The database
CAS REGISTRY at present contains more than 33 million organic and inorganic substances.
However, the little information regarding the potential hazard associated with a large amount of
chemicals is an old known problem in the European Union and also in the United States. This
critical problem may find a solution in the collaboration of the different involved countries and in
a planned task setting at international level. Both in the United States (e.g., the “Gore Initiative”)
and in European Union (the REACH policy) a big effort has been dedicated to this solution, within
standardized procedures and an appropriate collaboration.
