| 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. |
