Definition

Stack monitoring, also known as stack sampling, is a specialized environmental measurement technique used to assess and quantify the emissions of air pollutants and contaminants from industrial stacks or chimneys. It involves collecting and analyzing samples of gases and particulate matter discharged into the atmosphere from industrial processes. Stack monitoring is an essential tool for assessing compliance with emissions standards, tracking air quality impacts, and supporting environmental and public health protection efforts. Stack monitoring is a critical element of environmental protection, as it helps minimize air pollution, reduce impacts on air quality and public health, and ensure that industrial facilities operate within the boundaries of environmental regulations and emissions standards.
