BACKGROUND: Since its foundation in 2002, the Italian Silica Network (NIS), a collaborative network of professionals and public authorities, has been engaged in several aspects of research, control, and prevention of silica exposure and effects, and also in support for compensation claims for silica-related occupational health effects in Italy. METHODS: We start with a report on the NIS point of view concerning the recent scientific results (from epidemiology and laboratory studies), including those carried out by NIS in cooperation with Italian universities and other public agencies. This is followed by a description of the data on silica exposure in different Italian workplaces and guidelines for the management of occupational exposure to silica, as developed by two model regional programmes for the ceramics industry, metal foundries and tunnel excavation. RESULTS: The NIS initiatives highlighted the persistence of workplace conditions posing a significant risk for silica-related health effects, particularly in small industries and workshops. Experimental work has also shown that a number of physical and chemical factors affect the bioreactivity of silica particles. CONCLUSION: Based on NIS experience, it appears clear that currently conditions exist in Italy so as to positively contribute to the WHO Programme for the eradication of silicosis and the other diseases related to silica exposure. In order to achieve this goal, a coordinated and wide-ranging effort is required to reduce the wide gap in specific prevention activities, particularly in small industries and workshops, where high levels of silica exposure sometimes occur.

BACKGROUND: For a few years now in Italy there has been wide discussion on the advisability of developing health surveillance programmes for workers who were exposed to occupational carcinogens in the past (incompliance with Italian D.Lgs. 626/94, art. No. 69). The purpose of the present paper was to contribute to the discussion on operative guidelines for public or private Occupational Health Services intending to address this issue. METHODS: A cross-sectional survey was undertaken on former workers of a glass factory located in Leghorn, Italy. Six hundred and seventy-seven workers discharged in the period 1/1/1942 - 30/6/1992, with at least 1 year of service, resident in the area of Leghorn, were identified from the personnel records of the company and invited to medical examination at the local public Occupational Health Service. A structured questionnaire was developed in order to standardize the collection of occupational and health histories. RESULTS: 370 subjects were examined and for each of them occupational and health histories were collected. Occupational exposure to carcinogens in the factory in the last decades was reconstructed using the workers' occupational histories and the available plant records: 3 periods with different production activities (1942/49, 1950/69, 1970/92), and 4 main carcinogens (asbestos, PAH, silica and glass fibres) were identified. Thirty cancers were recorded and 10 of these were occupationally related. CONCLUSIONS: The health survey allowed occupational exposures to carcinogens to be defined in a factory where historical environmental data were not available. It was also possible to assess individual past occupational risk and provide information to each former worker on his risk, on available preventive measures, and on possible diagnostic, therapeutic and insurance procedures available in relation to diseases related to the different hazards. Via this survey it was also possible to identify and notify the Italian Institute of Insurance against Occupational Diseases and Accidents of 6 cases of bladder cancer, i.e., cancers with long survival that would be impossible to identify via current health data bases.
