Background: On the basis of the law which introduced the registration of occupational exposures to carcinogens (Legislative Decree 626/94), the National Institute for Occupational Safety and Prevention designed and implemented an information system for collecting and recording such information. The Ministry of Health Decree No 155/2007, which established the procedures for record keeping and transmission of registers of exposed workers, regulated the legislative fJamework in this field.
Objectives: The aim of the study was to illustrate some of the major legislative issues and toprovide summary statistics, after one year of entry into force of this Decree.
Methods: The main information to record is: the carcinogenic agents used, the type of occupational exposure and data on the environmental measurements. Descriptive statistical analysis were carried out, by sector of economic activity, carcinogen agent and worker's occupation.
Results: As at 31 December 2008 the information recorded, altogether, covered: 6000 firms, 79,000 workers, 164,000 exposures and 100,000 measurements. Most of the exposures occurred in the manufacturing and construction industries and in commercial activities.
Conclusions: Such surveillance system, established as a result of the institution of exposure registers, makes it possible to plan analytical studies, both for monitoring the effects of exposure, even at low doses, and for assessing the prevention and protection measures. It is hoped that the recent readjustment law (Legislative Decree 81/2008) will promote awareness of all subjects involved in the recording procedures (employers, physicians, local health units, research institutes, etc.), thus increasing the quality and coverage of data transmission.
