The analysis of lagging materials for asbestos: CEGB procedures
This article, by an author from the Central Electricity Generating Board (CEGB), described how the Board sampled and analysed thermal insulation (lagging) in its power stations for asbestos, and reviewed the analytical methods it used. It…

Measurement of asbestos fibre concentrations in fluid of repeated bro-choalveolar lavages of exposed workers
…Uncertainties related in general to lung residues and in particular to mineralogical analysis of BALF (mainly due to the high coefficient of variation (CV) at low fibre concentrations and the results of the statistical analysis on…

Asbestos Lung Burden in Necroscopic Samples from the General Population of Milan, Italy
…No AB were found in subjects younger than 30 years. Our study demonstrated detectable levels of asbestos fibres in a sample taken from the general population. The significant increase with age confirmed that amphibole fibres are…

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…

Nature of exposure to chrysotile
Fibres in general, and chrysotile fibres in particular, have properties that set them apart from other airborne particles in terms of their aerodynamic behaviour and the nature of their interactions with cells and fluids in vivo…

Asbestos and asbestosis
This short 1970 paper was not a research study but a general overview. It was originally presented at a 1969 conference on asbestos exposure during brake and clutch maintenance, and the author was Group Medical Adviser…

Asbestos dust concentrations in ship repairing: a practical approach to improving asbestos hygiene in naval dockyards
…the top of a ladder from the stripping area. Removing pipe lagging gave mean general levels of 171 fibres/cm3 in boiler rooms and 88 fibres/cm3 in engine rooms. Applying lagging gave much lower levels…

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…

Visibility of fine fibres of asbestos during routine electron microscopical analysis
…to the visibility of fine, sub-micrometre fibres. The results indicate that, in general, at a given magnification finer fibres are visible when using TEM than when using SEM. When using SEM, fibre visibility is improved…

Asbestos exposure during uncontrolled removal of sprayed-on asbestos
…bronchoalveolar lavage (lung-washing) fluid held 349 and 50 asbestos bodies per milliliter, versus under 1 expected in people of the general population without obvious asbestos exposure, and all fibers analyzed by electron microscopy were amosite…

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…

A study of the size distributions of airborne amosite fibres in the manufacture of asbestos insulation boards
…tasks such as bag opening, sawing and sanding, and in general areas. One filter of each pair was examined by optical phase contrast microscopy and the other by scanning electron microscopy (SEM). Fibre length distributions did…

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…

Case-control study on renal cell cancer and occupational exposure to trichloroethylene. Part I: Exposure assessment
…occupational physicians agreed with the authors' ratings for 23 of 32 job periods checked. The authors concluded their population could not be regarded as a typical general population. They called their distance corrections very crude estimates.

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…
