Kidney cancer and occupational exposure to asbestos: a meta-analysis of occupational cohort studies
Asbestos fibres discharged as a result of machine processing of brakes, are characterized by a lowered biological activity due to the fixation layer which covers them. This has been confirmed through occupational diseases' analysis and new data on malignant neoplasms epidemiology among workers engaged in machine processing of asbestos-moulded machine parts. General mortality caused by malignant neoplasms in these groups higher than in the control group, although statistically is not significant. This necessitates further epidemiologic studies to be performed at similar plants.
