目的锯木厂职业环境中生物气溶胶暴露可引起多种健康效应，尤其是呼吸系统损害、过敏和有机粉尘中毒综合征。该研究的目的是评估医疗呼吸系统和一般症状的频率和他们的关系bioaerosol exposure.Method 12锯木厂在法国的一部分，瑞士进行了调查和生物气溶胶（木尘，空气中的细菌，空气中的真菌和内毒素），医疗症状和肺功能受损的水平之间的关系进行了探讨。结果12个锯木厂空气中真菌浓度均超过瑞士国家保险（苏瓦）推荐的限值。真菌水平的升高显著影响了支气管综合征（咳嗽和咳痰）的发生。没有其他健康影响（刺激或呼吸影响）与测量的接触有关。我们观察到，初级工人比高级工人表现出更多的刺激综合征（定义为瘙痒/流鼻涕，打鼾和瘙痒/红眼）。肺功能测试没有受到影响的生物气溶胶水平，也没有粉尘暴露levels.Conclusion结果表明，职业暴露于木材粉尘在瑞士锯木厂不促进临床相关的肺功能下降。然而，支气管综合征的发生受到空气中真菌水平的强烈影响。
Objective Exposure to bioaerosols in the occupational environment of sawmills could be associated with a wide range of health effects, in particular respiratory impairment, allergy and organic dust toxic syndrome. The objective of the study was to assess the frequency of medical respiratory and general symptoms and their relation to bioaerosol exposure.Method Twelve sawmills in the French part of Switzerland were investigated and the relationship between levels of bioaerosols (wood dust, airborne bacteria, airborne fungi and endotoxins), medical symptoms and impaired lung function was explored. A health questionnaire was distributed to 111 sawmill workers.Results The concentration of airborne fungi exceeded the limit recommended by the Swiss National Insurance (SUVA) in the twelve sawmills. This elevated fungi level significantly influenced the occurrence of bronchial syndrome (defined by cough and expectorations). No other health effects (irritations or respiratory effects) could be associated to the measured exposures. We observed that junior workers showed significantly more irritation syndrome (defined by itching/running nose, snoring and itching/red eyes) than senior workers. Lung function tests were not influenced by bioaerosol levels nor dust exposure levels.Conclusion Results suggest that occupational exposure to wood dust in a Swiss sawmill does not promote a clinically relevant decline in lung function. However, the occurrence of bronchial syndrome is strongly influenced by airborne fungi levels.
