Title Respiratory symptoms, bronchial reactivity and occupational exposure to oak and beech dust
Original title Symptômes respiratoires, réactivité bronchique et exposition professionnelle aux poussières de chêne et de hêtre [in French]

Abstract The objective of the study was to investigate the relationship between levels of cumulative exposure to wood dust on one hand, and respiratory symptoms and onset of bronchial hyperreactivity (BHR) among oak and beech wood workers on the other. 114 men working in furniture manufacture exposed to wood dust were selected to participate in the study, together with 14 non-exposed controls and 200 "historical" controls, for whom data from earlier studies were available. Dust concentrations were measured in working air by personal sampling. Lung functions and bronchial hyperreactivity were tested, and medical history data were collected by means of a questionnaire. Results show what exposure levels are generally high, largely exceeding the average exposure limits of 1mg/m3 applied in France and proposed by the ACGIH. Among subjects exposed to oak and beech dust, the prevalence of laryngeal irritation and metacholine BHR increase rapidly with cumulative exposure.
