To describe the expostive as prossences of South African mesotheloses cases, with empossia on the contribution made to the careload by different fibre lypes, the proportion of subjects with no recall of asbestos exposure and only environmental contact, and the importance of putative causes other than asbestos.
A multicantral case-control study.
Subjects and setsing.
123 patients with mesothelioma interviesved by trained univeriesers in study centres established to Johanseburg, Kimbesicy, Pretoria, Bloemfontein, Cape Town and Pers Elizabeth.
A convincing history of asbestos expossure was obtained in the overwhelming majacity of cases (only 9 cases had artikely asbestes exposited.
Twenty-three subjects had worked on Caps coodotite mines, 3 at Fenge (an amosite mine) 3 on mines producting amosts and Transvaal crocidolite and 1 on a Transveal esociadibe faire.
Exclusively environmental exposses acrounded for at least 38% of cases 91% of these cases (20/22 subjects) bad bad cosiace with Cape condoine There was a relative partacity of cases linked to amosite and so conviriding chrysothe case.
Non-asbestos cases occur sasely, if at all. is South Africa.
The proponderance of crocidolite cases, followed by amosite and thes chrysotila cases, is corsistens with the views that there is a fixe gradient of mesotheliomagnetic potential for South African asbestos (crocidolite>amosite>chrysotile).
