Occupational exposure register-based cohort study on mortality among asbestos-related workers in Italy after the ban

Abstract

Objective: Asbestos is a human carcinogen and can cause some types of cancer, including mesothelioma. A relevant number of workers are still engaged in asbestos removal and disposal activities, whose actual risk of asbestos-related diseases is still scarcely recognized. The main objective of this study is to assess the cause-specific mortality among workers involved in asbestos removal and disposal after the ban in Italy.

Methods: Data from the Information System on Occupational Exposure to carcinogens (SIREP) in the period 1996-2018 were selected. Proportionate mortality ratios (PMRs) by cause of death were calculated by linking exposure occupational information to national mortality statistics (2005-2018), assuming a Poisson distribution of the data.

Results: A total of 142 deaths (all men) were identified among 13 715 asbestos removal and disposal workers. A significant excess ( P < 0.05) of mesothelioma deaths was found among male workers, about five-fold the expected. A significant increase in the mortality ratio was also found for malignant melanoma of skin.

Conclusions: A risk of mesothelioma has been found among workers involved in asbestos removal and disposal. Epidemiological surveillance and promotion of prevention action plans are highly recommended for workers engaged in asbestos removal and disposal activities, to ensure compliance with regulatory requirements and reduce the still relevant risk of contracting the related tumor pathology.
