The limit values for chemical agents in light of the REACH regulation [I valori limite per agenti chimici alla luce del Regolamento REACH]

The European Regulation 190712006 (REACH - Registration, Evaluation, Authorization and Restriction of Chemicals) obliges manufacture companies and import chemicals to assess the risks arising from their use and to take the necessary measures to manage the risks identified. The Chemical Safety Report provides an accurate assessment of hazards to human health and the environment necessary to prepare an exposure scenario for the "identified uses" of the substance. An exposure scenario is the set of conditions that describe how the substance is manufactured or used during its life cycle and how the manufacturer or importer controls, or recommends downstream users to control the 'exposure to humans and the environment. Firms therefore need specific skills. The spectrum of toxicological risk is extremely large, the information required in some cases are very complex and undoubtedly require a thorough knowledge in toxicology and environmental industry. The expertise and experience in toxicology of the occupational physician in this case may become useful in the environmental field as well as another familiar figure of relevant importance is the occupational hygienist who develop exposure scenarios for workers and their uses experience for the exposure scenarios for the consumer. It provides an obvious involvement of medical toxicologists and occupational hygienists for public tasks of control and inspection of chemical safety reports and, locally, even the accuracy of risk that arise from this.
