Detection of mineral fibre carcinogenicity with the intraperitoneal test--recent results and their validity
The general experimental design of intraperitoneal (i.p.) carcinogenicity studies with inorganic fibres in rats is described. In a current study, in addition to glass microfibres, size-separated fine respirable fractions of commercial insulation wools (MMVF…

Estimating the number of asbestos-related lung cancer deaths in Great Britain from 1980 to 2000
…to 2000 (excluding 1981) were calculated for occupational groups. Smoking indicators were developed from three General Household Surveys carried out during the 1980s and 1990s. Poisson regression models were used to estimate the number of asbestos…

The combined effects of smoking and occupational or urban factors in relation to lung cancer
…risk in certain occupational groups, studies on general populations show that the effect of smoking is large compared with that of "urban" factors and there is no indication of any interaction between smoking and air pollution.

Biological effects: asbestos-cement manufacturing
… if so, then the no-threshold model for lung cancer risk is inappropriate since there is general agreement that very low exposures will not result in radiologically detectable lung fibrosis. Further data on this potential link…

Lung fibre burden in lung cancer cases employed in the rock and slag wool industry
…dry lung. Asbestos fibres were found in 16 cases in minor amounts, described by the authors as similar to general-population levels. Lung fibre levels did not follow estimated exposure to MMVF or asbestos, and age…

The effect of smoking on the risk of lung cancer mortality for asbestos workers in Great Britain (1971-2005)
Workers in the asbestos industry tend to have high smoking rates compared to the general population. Both asbestos exposure and cigarette smoking are recognized risk factors for lung cancer mortality, but the exact nature of the…

Current opinions on the asbestos cancer problem
This article was a synopsis of a recent review of epidemiological studies and a general summary by the same author, drawing on opinions expressed at the 1969 Pneumoconiosis Conference in Johannesburg. The author described international studies…

Asbestos fibre burden in the lungs of patients with mesothelioma who lived near asbestos-cement factories
…residence to both plants. To provide information on the intensity of environmental asbestos exposure, in the general population living around these factories, through the evaluation of the lung fibre burden in mesothelioma patients. We analysed by…

Epidemiology of malignant mesothelioma--an outline
…the 20-year period, 1974-1994, showed a wide range of outcomes, but in general that the risk was higher in exposures which included amphiboles rather than chrysotile alone. Real progress began, however, with discoveries along…

Carcinogenesis and related cell and tissue responses to asbestos: a review
…of lung cancer. Several caveats important in the interpretation of these data include the general lack of dose-response protocols both for in vivo and for in vitro studies as well as the absence, in many…

The combination of effects on lung cancer of cigarette smoking and exposure in quebec chrysotile miners and millers
…equivalent to exposure amounting to 700 million particles per cubic foot x years. The refutation of the multiplicative hypothesis in these data reinforces its inapplicability in general; but the additive hypothesis is not generally applicable either…
