“…Limited information regarding the potential benzene exposure associated with dock tasks has been reported (7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20). These papers reported potential exposure sources at docks, including venting of displaced vapors during material transfers, spills, and clothing contamination from contact or splashes (21).…”

“…[6][7][8] On crude oil tankers, the exposure to benzene, for example, is considerably lower than on product tankers, and the risk estimates were also generally lower for work on crude oil tankers.…”

“…4 5 Benzene concentrations up to some 100 ppm have been measured during tank cleaning, loading, and unloading of gasoline and some other light refinery products. [6][7][8] Benzene is a well known leukaemogen 9 and has also been suspected to cause other malignancies such as lymphoma, including multiple myeloma. [10][11][12][13] The results of a large benzene cohort study, recently published, showed a significant excess of leukaemia and lymphoma and a significant trend in the dose-response for both of these types of cancer separately.…”

Objectives-To investigate the risk of lymphatic and haematopoietic malignancies in deck crew on tankers exposed to cargo vapours. Methods-The study design was as a nested case-referent study in two cohorts of male Swedish seamen 20-64 years of age at the national census 1960 (n 13 449) and 1970 (n 11 290), respectively. Cases were detected by record linkage with the Swedish Cancer Register 1961-79 and 1971-87, respectively. For each case, three to five age matched referents from the population were selected. Exposure was assessed from data in the Swedish Registry of Seamen and from a register of Swedish ships. Results-Seamen in the 1970 cohort, who had been exposed to cargo vapours for at least one month on chemical or product tankers, had an increased risk of lymphatic and haematopoietic malignancies (Mantel-Haenszel odds ratio (OR) 2.6, 95% confidence interval (95% CI) 1.1 to 5.9)) with a significant exposure-response relation (conditional logistic regression analysis, p=0.04). The ORs were increased for both lymphoma (3.2), multiple myeloma (4.0), and leukaemia (1.6), but the increase was only significant for nonHodgkin's lymphoma (OR 3.3, 95% CI 1.1 to 10.6). There were no significantly increased risks for the 1960 cohort or for seamen exposed only on crude oil tankers, but these groups had few exposed cases and low cumulative exposure to benzene and other light petroleum products. Conclusions-Seamen exposed to cargo vapours from gasoline and other light petroleum products on chemical or product tankers had an increased incidence of lymphatic and haematopoietic malignancies. One possible cause is exposure to benzene during loading, unloading, and tank cleaning operations. (Occup Environ Med 1998;55:517-521)

“…2 In the engine rooms of ships there are exposures to different type of hydrocarbons, 3 and on ships carrying oil products and chemicals, exposure to carcinogenic substances may take place. 4 Smoking is frequent in most maritime environments, and obesity has become frequent as the manual workload has been reduced and food become more abundant. 5 Many seafarers are, as a part of the job, international travellers, and are known to have a risk of hepatitis A and B, HIV infection, and tuberculosis.…”

Aims: To study morbidity among active seafarers in the merchant navy in order to clarify possible work related morbidity and the morbidity related to work and lifestyle where possible preventive measures may be initiated. Methods: From a register in the Danish Maritime Authority a cohort of Danish merchant seafarers who had been actively employed at sea in 1995 was identified. For each seafarer, information on all employment periods at sea, charge aboard, and ship was available. The cohort was linked with the National In-patient Register in Denmark. Standardised hospitalisation ratios (SHRs) were calculated for all major diagnostic groups using all gainfully employed as reference. Results: Seafarers were shown to be inhomogeneous, with significant differences in SHRs for the same disease groups between different groups of seafarers depending on charge and ship type. SHRs for lifestyle related diseases were high, although rates for acute conditions, such as acute myocardial infarction, were low, probably due to referral bias, as acute conditions are likely to cause hospitalisation abroad, and thus are not included in the study. SHRs for injury and poisoning were high, especially for ratings and officers aboard small ships. Conclusion: Despite pre-employment selection, a large proportion of the seafarers constitute a group of workers with evidence of poor health probably caused by lifestyle. The subgroups with high risk of hospitalisation due to lifestyle related diseases also had an increased risk of hospitalisation due to injury and poisoning.
