      <subfield code="a">An epidemiological, immunological, and environmental investigation was undertaken of both current and ex-workers at the sawmill and of a control population not occupationally exposed to wood or wood products. This study has shown that exposure to wood dust at the sawmill was associated with an increased prevalence of symptoms related to nasal and conjunctival irritation and with a high prevalence of symptomatic bronchial hyper-reactivity. Sawmill workers exposed to high concentrations of dust had more work related respiratory symptoms than those exposed to lower dust concentrations and cases of extrinsic allergic alveolitis only occurred in the more heavily exposed group</subfield>
