13. Frequency of sister chromatid exchange and chromosomal aberrations in asbestos cement workers.
Exposure to asbestos minerals has been associated with a wide variety of adverse health effects including lung cancer, pleural mesothelioma, and cancer of other organs. It was shown previously that asbestos samples collected from a local asbestos factory enhanced sister chromatid exchanges (SCEs) and chromosomal aberrations in vitro using human lymphocytes.

14. Individual asbestos exposure: smoking and mortality--a cohort study in the asbestos cement industry.
A historical prospective cohort study comprised all persons employed from 1950 to 1981 for at least three years in the oldest asbestos cement factory in the world. From 2816 persons eligible for the study, record based estimates and measurements of dust and fibres and histories of smoking based on interviews were used to calculate individual exposures over t

15. Mortality of workers in a French asbestos cement factory 1940-82.
The mortality of a complete cohort of 1506 French asbestos cement workers employed for at least five years is related to the time elapsed since first exposure. The mortality from all causes (analysed by the "man-years method") has been found to be above normal only in those subjects employed for more than 20 years, with more than 35 years of follow up.

16. Pleural malignant mesothelioma and non-occupational exposure to asbestos in Casale Monferrato, Italy.
OBJECTIVES--To assess and quantify the occurrence of pleural malignant mesotheliomas in people who neither experienced occupational exposure to asbestos nor were married to (or known to live with) workers exposed to asbestos in the workplace. The study was conducted in the area of the local health authority of Casale Monferrato, in north western Italy, where

17. Baseline characteristics are not sufficient indicators of non-response bias follow up studies.
STUDY OBJECTIVE--The aim was to examine whether baseline characteristics from a cross sectional survey provided sufficient information regarding non-response bias in a follow up study when compared with information on hospital admissions in the intervening years. DESIGN--This was an 11 year follow up study of a cohort selected in 1974 with register informati

18. Incidence of cancer and mortality among employees in the asbestos cement industry in Denmark.
In a cohort study of the incidence of cancer and mortality among 7996 men and 584 women employed in the Danish asbestos cement industry between 1928 and 1984 over 99% were traced. Chrysotile asbestos was the only fibre type used until 1946, when amosite and (in 1952) crocidolite were also introduced. Chrysotile constituted 89%, amosite 10%, and crocidolite 1

19. Biphasic lung diffusing capacity: detection of early asbestos induced changes in lung function.
Asbestos related changes in the single breath carbon monoxide diffusing capacity (DLCO) were longitudinally analysed in 14 subjects exposed predominantly to chrysotile asbestos in an asbestos cement factory. These subjects were examined annually over the past nine years; their lung function was initially characterised with increased DLCO as the sole function
