Mesothelioma and lung tumors attributable to asbestos among petroleum workers

Most cases of mesothelioma are probably related to past exposure to asbestos in refineries. No occupational cause has been identified for the excess of melanoma, or prostatic or bladder cancer. The possibility of a causal relationship between cancer of the kidney and hydrocarbon exposure warrants further study. It is uncertain whether benzene exposures, particularly past levels of exposure, have been high enough to cause ANLL.

Trends in asbestos body counts in bronchoalveolar lavage fluid over two decades. P. Dumortier, J. Thimpont, V. de Maertelaer, P. De Vuyst. #ERS Journals Ltd 2003. ABSTRACT: As in most western countries, the use of asbestos has decreased in Belgium since the mid 19709s. Successive regulations have lowered the permissible levels of exposure and prohibited the use of various asbestos products.In order to assess the impact of these prevention measures on the pulmonary fibre burden of asbestos-exposed patients, the bronchoalveolar lavage fluid (BALF) asbestos body (AB) analysis database of the authors9 laboratory was reviewed for the period 1983-2000.A total of 4,772 cases were considered, of which 95% were males. AB concentration exceeded 1 AB?mL BALF -1 in 36.1%. There was essentially no change in the mean concentration of AB over the period evaluated. However, the concentrations in individuals with very high levels decreased over time. This was associated with a shift in exposure categories from primary asbestos workers to those exposed during handling of asbestos-containing materials or to asbestos in place in buildings or industrial sites. This is consistent with epidemiological data indicating that the number of severe cases of asbestosis caused by very high cumulated doses decreases but that benign pleural diseases and mesothelioma remain the most frequent asbestos-related diseases. Past prevention measures are not expected to have a measurable influence on the incidence of mesothelioma in the near future.

“…The raw material is gathered from the mountains by men and applied to the house wall by women. It is also used as a substitute for baby powder, and on roofs for insulation and prevention of water leakage (Gennaro et al 2000;Seaton 2002;Yazıcıog˘lu et al 1973). Thus, those living in houses are chronically exposed to the dust, and children grow up in houses with asbestos-contaminated air.…”
