Abstract

Bioaerosol sampling is a critical step toward characterizing airborne pathogen exposure risks for many respiratory infectious diseases in human-to-human or human-to-animal outbreaks. The integrated performance-parameter design and sampling efficiency of aerosol-to-hydrosol samplers (cyclones) has been rarely published or studied. This review focuses on the determination of cyclone performance-parameter design and impact factors of the sampling efficiency, discusses their mechanisms of collection and describes their advantages and drawbacks. The crucial design parameters of cyclones in different applications are then discussed in detail. We also discuss how the aerosol-to-hydrosol sampling efficiency is intrinsically related to the performance parameters for bioaerosol cyclone design. In the final section of this review, scientific questions and challenges for future work are presented to encourage high collection efficiency design and high-quality cyclones.

摘要

生物气溶胶采样是表征人与人或人与动物暴发中许多呼吸道传染病的空气传播病原体暴露风险的关键步骤。气溶胶-水溶胶采样器（旋风分离器）的综合性能参数设计和采样效率很少发表或研究。这篇综述着重于确定旋风分离器的性能参数设计和采样效率的影响因素，讨论它们的收集机理并描述其优缺点。然后详细讨论了旋风分离器在不同应用中的关键设计参数。我们还讨论了气溶胶到水溶胶的采样效率如何与生物气溶胶旋风分离器的性能参数本质上相关。在本评论的最后部分，
