Associations between the presence of chronic respiratory symptoms and a history of working in certain production job categories within the rubber industry are presented. Environmental explanations for these associations are discussed. Particular attention is also paid to the methodologic difficulties in analyzing cross-sectional health data in relation to the mobile and environmentally varied work-histories of individual workers within the rubber industry.
