SIZE DISTRIBUTIONS OF CHRYSOTILE ASBESTOS IN A FRICTION PRODUCTS FACTORY AS DETERMINED BY TRANSMISSION ELECTRON MICROSCOPY
Abstract
Airborne chrysotile asbestos size distributions have been measured by transmission electron microscopy from air samples taken in a factory making clutches and brake shoes. The median diameters on samples taken at the three processes were 0.08, 0.13 and 0.13 μm, and the median lengths were 0.86, 1.4 and 1.5 μm. Median aspect ratios were close to 10. A few per cent of fibres were longer than 5 μm, and between a fifth and a half of these would be counted by a phase-contrast optical microscope resolving 0.3 μjm.

Each is checked against this paper’s own text: does it say what the citing paper says it does?
In the citing paper
“In these studies the non-regulated fibers, SAF, and LAF with a diameter < 0.2 μm, represented between 50 and 100% of the total fibers, with the majority of samples between 80 and 100% respectively.”

In the citing paper
“Analysis of asbestos size categories according to sectors of activity and the concentration levels found in the literature [10-18] highlight a number of sectors with higher prevalence of SAF, including in particular asbestos cement production, friction materials production, brake systems repair and mining.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
