对埃塞俄比亚20家中小型木材加工企业的木材粉尘暴露情况进行了研究。从2013年1月至6月每天进行采样，使用职业医学研究所(IOM)个人采样器采集了113名工人的360份样本。8小时木尘暴露时间加权平均值为0.24~23.3 mg m(-3)，几何平均值为6.82 mg m(-3)，几何标准差为1.82。虽然埃塞俄比亚没有木尘暴露的职业暴露限值的界定标准，但71%的测量值超过了欧洲联盟(欧盟)规定的5毫克m(-3)的限值。当工人进行打磨和锯切活动时，测得的GM值分别为9.72和7.60 mg m(-3)，高于欧盟接触限值。综上所述，中小型企业的木材工人有持续接触的趋势，患各种呼吸道健康问题的风险更高。
A study of wood dust exposure in 20 small- and medium-scale wood-processing enterprises was performed in Ethiopia. Sampling was conducted daily from January to June, 2013 and a total of 360 samples from 113 workers were collected with Institute of Occupational Medicine (IOM) personal samplers. Eight-hour time-weighted average exposure to wood dust ranged from 0.24 to 23.3 mg m(-3) with a geometric mean (GM) of 6.82 mg m(-3) and a geometric standard deviation of 1.82. Although Ethiopia did not have any defined standard of Occupational Exposure Limit for wood dust exposure, 71% of the measurements exceeded the limit of 5 mg m(-3) set by the European Union (EU). Higher than the EU exposure limit was measured while workers perform sanding and sawing activities with a GM of 9.72 and 7.60 mg m(-3), respectively. In conclusion, wood workers in the small-and medium-scale enterprises are at a higher risk of developing different respiratory health problems with continuous exposure trends.
