The accurate and efficient determination of the trace elements in agricultural products and their field environment is important for the government regulation towards trace elements in agricultural products, ensur⁃ing consumer safety, and promoting the high-quality development of the grain and oil industry. This paper reviews the detection techniques of the trace elements in agricultural products and their producing field environment in re⁃cent years. The principles and characteristics of spectroscopy, mass spectrometry, chromatography and electrochem⁃istry were compared and analyzed, and the practical application advantages and disadvantages of these detection techniques were discussed. This paper provided an reference for the research of the trace elements detection tech⁃nology in agricultural products and their producing field environment, as well as technical support for high quality development of grain and oil industry and their products.
