Personal and ambient full shift concentrations of inhalable wood dust were measured at different wood-working processes in two joineries and a furniture factory in The Netherlands. The current occupational exposure limit for wood dust is still 5 mg m-3 total dust, but the Dutch Expert Committee for Occupational Standards has recently recommended a health-based limit of 0.2 mg m-3 (total wood dust). The main purpose of the present study was to characterize current wood-dust exposures during different wood-working activities in order to determine whether compliance with the proposed limit was feasible. The wood-dust exposures in the joineries were usually much lower than 5 mg m-3, but in the furniture factory the present limit was regularly exceeded. Sanding, especially hand sanding, nearly always resulted in exposures above 5 mg m-3. Almost all personal exposures were higher than the proposed health-based limit of 0.2 mg m-3 and therefore can be considered to generate a health risk to the workers. The measurements performed may help in setting priorities and will serve as a basis for the development of a control strategy to reduce the average exposure.
在荷兰的两家细木工车间和一家家具厂，对不同木工工序中可吸入木尘的个人和环境全时段浓度进行了测量。目前木尘的职业接触限值仍为总粉尘5毫克/立方米，但荷兰职业标准专家委员会最近建议基于健康的限值为0.2毫克/立方米（总木尘）。本研究的主要目的是描述不同木工活动期间当前的木尘暴露情况，以确定是否可行地遵守拟议的限值。细木工车间的木尘暴露通常远低于5毫克/立方米，但在家具厂，目前的限值经常被超过。打磨，尤其是手工打磨，几乎总是导致暴露超过5毫克/立方米。几乎所有的个人暴露都高于拟议的基于健康的0.2毫克/立方米的限值，因此可认为会给工人带来健康风险。所进行的测量有助于确定优先事项，并将作为制定控制策略以降低平均暴露的基础。
