Title The evaluation of chrysotile asbestos fibre levels in major chrysotile cement manufacturing companies in Zimbabwe
Bibliographic information Sep. 2005, Vol.11, No.3, p.7-11. 8 ref.
Abstract Zimbabwe mines chrysotile asbestos and manufactures asbestos cement pipes and sheets, brake linings and gaskets. The objective of this study was to assess exposure levels in the chrysotile manufacturing industries. A total of 40 personal and environmental samples were collected at two manufacturing sites. Only one area was found to have fibre levels above the acceptable limit of 0.2 fibres/ml set voluntarily by the Zimbabwean industry and all samples were below the proposed threshold limit value of 0.5 fibres/ml.
