[Chemical risks. From the risk assessment to the sanitary surveillance: evolution of the instruments of the occupational health].

Following the development of Legislation, the Occupational Health activities become more articulated and complex from both a formal and essential point of view and they are becoming an ever increasing part of the Health and Safety preventative strategy at the workplace and in its surrounding environment. In this context Health Surveillance, including its risk assessment aspect, is not any more only the straightforward application of medical methods aimed at identifying work related pathologies, but it assumes a preventative role in the evaluation of the individual exposure to the work environment i.e. to chemical and biological substances. To carry out such activities, in addition to the ones normally used, new instruments of information are available, provided by recent legislation, that regulates in a coordinated way the worker's health protection at the workplace, in particular the Regulation n. 1907/2006 (REACH) and the Regulation n.1272/2008 (CLP).
