摘要

空气污染仍然是政府、监管机构和公众关注的问题。扩散或被动采样器提供了一种具有成本效益，多功能和空间密集的空气污染采样方法，不需要操作传统空气质量监测仪器所需的大量投资。本技术简介介绍扩散采样器的原理和操作，以及如何校准其采样率。它还讨论了在室外环境中部署扩散采样器的考虑因素，并提供了它们在采样不同空气污染物中的实际使用示例。

Diffusive samplers for ambient air quality monitoring

Air pollution remains a matter of concern for governments, regulators and the general public. Diffusive, or passive, samplers provide a cost-effective, versatile and spatially dense method to sample air pollution that does not require the significant investment needed to operate traditional air quality monitoring instrumentation. This Technical Brief describes the theory and operation of diffusive samplers and how their sampling rates may be calibrated. It also discusses considerations for the deployment of diffusive samplers in outdoor environments and provides examples of their practical use in sampling different air pollutants.
