Asbestos fibers in wines: relation to filtration process.
Asbestos fibers have been counted, using the transmission electron microscope, in 42 wines from France and abroad. 15 samples were found to be significantly positive for chrysotile asbestos. Concentrations were in the range of 2 to 60 x 10(6) fibers/liter. Technical inquiries have shown that the asbestos content of the wines was related to the process by which they were filtered. On the other side, it has been tested that if one abolished the use of asbestos for filtering wines, they would not be altered from the oenological point of view.

[Peripheral airway obstruction in the course of occupational exposure to asbestos].
Typically, the functional abnormalities in individuals exposed to asbestos dust take the form of a pulmonary fibrosis. Recently, several authors have stressed the early existence of small airways obstruction. In the present study, by measurement of closing volume, we have confirmed an obstructive factor in a certain number of exposed subjects, even if they were non-smokers, i.e. had no other apparent reason for small airways disease.

[Topographical variations of pulmonary and pleural asbestos fiber concentrations in variously exposed subjects].
The authors study three groups of subjects with different exposures to asbestos dust. The lung content in asbestos fibres is measured by optical and electron microscopy, the latter technique revealing preferential concentration of asbestos fibres in the peripheral zones of the lung, in particular in individuals subject to a moderate degree of professional exposure.
