Mesothelioma Risk among Construction Workers According to Job Title: Data from the Italian Mesothelioma Register

Background: An increased risk of mesothelioma has been reported in various countries for construction workers. The Italian National Mesothelioma Registry, from 1993 to 2018, reported exposure exclusively in the construction sec-tor in 2310 cases. We describe the characteristics of these cases according to the job title. Methods: We converted into 18 groups the original jobs (N=338) as reported by ISTAT codes ('ATECO 91'). The exposure level was attributed to certain, probable, and possible in accordance with the qualitative classification of exposure as reported in the Registry guidelines. Descriptive analysis by jobs highlights the total number of subjects for every single job and certain expo-sure, in descending order, insulator, plumbing, carpenter, mechanic, bricklayer, electrician, machine operator, plasterer, building contractor, painter, and laborer. Results: The cases grow for plumbing in 1993-2018, while, as expected, it decreased for the insulator. Within each period considered, the most numerous cases are always among bricklayers and laborers; these data confirm the prevalence of non-specialized "interchangeable" jobs in the Italian construction sector in the past. Conclusions: Despite the 1992 ban, the construction sector still presents an occupational health preven-tion challenge, and circumstances of asbestos exposure may still occur due to incomplete compliance with prevention and protection measures

Mesothelioma Risk Among Maritime Workers According to Job Title: Data From the Italian Mesothelioma Register (ReNaM)

Background: The study describes the 466 cases of malignant mesotheliomas (MM) collected by the National Meso-thelioma Register (ReNaM) in Italy from 1993-2018 relating to subjects with exclusive asbestos exposure in mer-chant or military navy. Methods: The cases among maritime workers represent 1.8% of the total patients with defined exposure registered in the ReNaM, of which (45.4%) were among merchant maritime workers and 254 cases (54.5%) among the navy. The distribution by site of mesothelioma showed 453 (97.2%) MM cases of the pleura, 11 (2.3%) of the peritoneum, and 2 (0.4%) of the tunica vaginalis of the testis. With regard to occupational exposure, it was classified as certain in 318 (68.2%) cases, probable in 69 (14.8%) cases, and possible in 79 (16.9%) cases. Results: Among the 23 classified jobs, the highest percentages of certain exposures are among naval engineers, motor mechanics, machine captains, and sailors. Machine crew accounted for 49.3% of the cases, and deck crew for 27.6%. All cases began exposure on board between 1926 and 1988. Seamen were exposed to asbestos while at sea by living onboard ships and from the continual release of asbestos fibers due to the motion of a vessel. Conclusions: Epidemio-logical surveillance through the ReNaM has allowed us to verify among cases in the maritime, navy, and merchant marine sectors that, in the past, subjects were exposed regardless of the ships' department where they have provided service; therefore, all these cases must be considered occupational diseases
