Abstract: :In recent years,due to the wide use of 1,1-dimethylhydrazine(UDMH) in the aerospace industry,the its impact on human health cannot be ignored. Therefore,how to detect UDMH in the environment accurately and efficiently become a research hotspot. However,it is difficult to detect UDMH because of its strong reducibility and inflammability. The article reviews the research on the detection of UDMH in the environment in recent years,introduces the similarities and differences of different detection methods such as liquid chromatography,gas chromatography,mass spectrometry,and sensor method,as well as summarizes the limits of detection,linear range,and recoveries of different methods.

Key words: 1,1-dimethylhydrazine, Environment exposure, Detection methods
