Seamen and marine engineers were formerly exposed to asbestos used in gasket, pipes, valves and machinery. Ship motion and vibration can release asbestos in the surrounding space. Asbestos fibres may also be inhaled by workers involved in maintenance operations of vessels built before 1992 in Italy. History of asbestos exposure has been reported by workers and confirmed by a higher prevalence of pleural abnormalities and a significant excess of mesothelioma with a Standardized Incidence Ratio (SIR) ranging between 1.83 and 4.8 as a function of years of exposure. SIR for lung cancer ranged between 1.10 and 1.62. Mesothelioma in seamen and marine engineers represents about 2.5% of the overall Italian mesothelioma cases with a very long latency period (47.6 +/- 9.6 years). There is no epidemiological evidence for an excess risk of mesothelioma in fishermen.
海员和轮机工程师以前接触过用于垫圈、管道、阀门和机械中的石棉。船舶的运动和振动会使石棉释放到周围空间。在意大利，参与1992年以前建造船舶维修作业的工人也可能吸入石棉纤维。工人报告了石棉接触史，并通过胸膜异常的较高患病率以及间皮瘤的显著超额发病率得到证实，标准化发病比（SIR）在1.83至4.8之间，取决于接触年限。肺癌的标准化发病比在1.10至1.62之间。海员和轮机工程师中的间皮瘤约占意大利间皮瘤病例总数的2.5%，潜伏期很长（47.6±9.6年）。没有流行病学证据表明渔民中间皮瘤风险增加。
