BACKGROUND
Tasks involved in traditional charcoal production expose workers to various levels of charcoal dust and wood smoke. This study aimed to identify specific tasks influencing lung function and respiratory symptoms.
METHODS
Interviews, direct observation, and task/symptom checklists were used to collect data from 50 charcoal-production workers on 3 nonwork days followed by 11 workdays. The peak expiratory flow rate (PEFR) was measured four times per day.
RESULTS
The PEFR was reduced and the prevalence of respiratory symptoms increased over the first 6-7 workdays. The PEFR increased until evening on nonwork days but not on workdays. Loading the kiln and collecting charcoal from within the kiln markedly reduced the PEFR and increased the odds of respiratory symptoms.
CONCLUSION
Tasks involving entry into the kiln were strongly associated with a short-term drop in the PEFR and the occurrence of respiratory symptoms, suggesting a need for the use of protective equipment and/or the operation of an effective kiln ventilation system.
背景
传统木炭生产所涉及的任务会使工人接触到不同程度的木炭粉尘和木烟。本研究旨在确定影响肺功能和呼吸道症状的具体任务。
方法
通过访谈、直接观察以及任务/症状清单，在3个非工作日及随后的11个工作日从50名木炭生产工人处收集数据。每天测量4次呼气峰值流速（PEFR）。
结果
在最初的6至7个工作日中，PEFR降低，呼吸道症状的患病率增加。在非工作日，PEFR直至傍晚都会升高，但在工作日则不然。往窑中装料以及从窑内收集木炭会显著降低PEFR，并增加出现呼吸道症状的几率。
结论
涉及进入窑内的任务与PEFR的短期下降以及呼吸道症状的发生密切相关，这表明需要使用防护设备和/或运行有效的窑通风系统。
