Prevalence of pleural calcification in persons exposed to asbestos dust, and in the general population in the same district
…not minus only the 8. Each exposed group had more cases than expected from the general population (workers: 42 against an expected 2.75). The authors reported these differences as statistically significant at the 1% level…

Cancer incidence of Taiwanese shipbreaking workers who have been potentially exposed to asbestos
…number of cancers for shipbreaking workers was calculated by using the age (5-year intervals) and calendar time-specific annual rates of cancer incidence with reference to the general population of Taiwan from 1985 to 2008…

Gender differences in pleural mesothelioma occurrence in Lombardy and Piedmont, Italy
…exposure in men translated into a 7 to 10 year advancement in mesothelioma occurrence. They noted that exposure information was not available for the general population, so rates by actual asbestos exposure could not be calculated.

Electron diffraction patterns of U.I.C.C. asbestos samples
…electron diffraction patterns was studied using a double-tilt stage. Rotation did not have a nurked effect on the general pattern of weak and strong spectra. It has been shown that electron diffraction nlethod may ha…

Metallic elements in crude and milled chrysotile asbestos from Quebec
…present at very low levels, and calcium was not detected in crude fibers. Milled fibers showed a general increase in all metals, by factors from 1.3 to more than 15. Chromium and nickel were many…

Asbestos related disease in Barrow-in-Furness
…carcinoma deaths, and 13 versus 2 mesothelioma deaths. Autoantibody levels in 160 men with plaques did not differ significantly from those in the general British population. The author concluded that shipyard workers with plaques, without fibrosis…
