Measurement of worker exposure to a thoracic health-related aerosol fraction is necessary in a number of occupational situations. This is the case of workplaces with atmospheres polluted by fibrous particles, such as cotton dust or asbestos, and by particles inducing irritation or bronchoconstriction such as acid mists or flour dust. Three personal and two static thoracic aerosol samplers were tested under laboratory conditions. Sampling efficiency with respect to particle aerodynamic diameter was measured in a horizontal low wind tunnel and in a vertical calm air chamber. Sampling performance was evaluated against conventional thoracic penetration. Three of the tested samplers performed well, when sampling the thoracic aerosol at nominal flow rate and two others performed well at optimized flow rate. The limit of flow rate optimization was found when using cyclone samplers.
在许多职业情况下，测量工人接触与胸部健康相关的气溶胶部分是必要的。这种情况涉及到被纤维颗粒污染的工作场所，如棉尘或石棉，以及会引起刺激或支气管收缩的颗粒，如酸雾或面粉尘。在实验室条件下测试了三种个人和两种静态胸部气溶胶采样器。在水平低风洞中测量了粒子空气动力学直径的采样效率，并在垂直静止空气室中进行了测量。采样性能与常规胸部穿透进行了评估。当以标称流速采样胸部气溶胶时，其中三种测试采样器的性能良好，而另外两种在优化流速时性能良好。当使用旋风采样器时，发现了流速优化的限制。
