A randomly selected group of 50 New Zealand wood workers was studied. The level of airborne wood dust to which they were exposed ranged from 1.0-24.5 mg/m3. The wood workers reported experiencing higher rates of both lower and upper respiratory tract symptoms than a control group of office workers. Inhaled wood dust, in particular from rimu (Dacrydium cupressinum), was frequently cited by workers as being associated with respiratory tract symptoms. The wood workers' responses to the respiratory symptom questionnaire, and serial recordings of peak expiratory flow rate were used to screen the group for suspected cases of occupational asthma. Five cases fulfilled the study's criteria for suspected occupational asthma. In four of these, further evidence was found to support this diagnosis. We conclude that exposure to wood dust may cause occupational asthma in the woodworking industry in New Zealand.
对随机抽取的50名新西兰木工进行了研究。他们接触的空气中木尘水平在1.0至24.5毫克/立方米之间。与办公室工作人员对照组相比，木工报告的下呼吸道和上呼吸道症状发生率更高。工人经常提到吸入木尘，特别是来自芮木泪柏（扁柏属）的木尘，与呼吸道症状有关。通过木工对呼吸道症状问卷的回答以及呼气峰值流速的系列记录，对该组进行筛查以找出疑似职业性哮喘病例。有5例符合该研究的疑似职业性哮喘标准。其中4例发现了进一步支持该诊断的证据。我们得出结论，接触木尘可能会在新西兰的木工行业中导致职业性哮喘。
