Research progress on interference in the detection of pollutant gases and improving technology in livestock farms: A review

摘要

With the intensive development of large-scale livestock industry, the gas emissions from livestock farms were identified as a major problem. Many greenhouse gases and odorous gases are generated from animal exhalation, ruminant fermentation, livestock waste, and other factors. Considering the environmental impact brought by pollutant gas emissions, it is important to determine how it contributes to total emissions accurately in order to minimize it. This article gives a comprehensive overview over the non-spectroscopic techniques and spectroscopic techniques applied to air quality assessment in livestock. In addition, this review summarizes interferences in the detection process, emphasizing different interference reduction approaches for improving the performance of current detection technologies used in livestock farms.
