Issue 14/2015 - Breakthrough in agricultural chemical pollutant residue detection technology in China

Recently, the "Detection Technology and Behavior of Agricultural Chemical Pollutants Residue" team, led by Wang Jing, a researcher at the Institute of Agricultural Quality Standards and Testing Technology, Chinese Academy of Agricultural Sciences, has made breakthroughs in the detection technology of chemical typical pollutants in agricultural products after years of efforts, and the accurate identification and confirmation detection technology it has constructed has played a positive role
in solving the problems of incomplete varieties, low detection sensitivity, and cumbersome sample preparation for rapid detection of agricultural products in China.
The results passed the outcome evaluation
organized by the Chinese Agricultural Society.

The project designed and invented six types of molecularly imprinted solid phase extraction columns such as triazine pesticides, and established a rapid sample pretreatment technology platform with strong enrichment ability, good purification effect and environmental friendliness.
The effect of the interaction between catalyst and enhancer on the stability of the chemiluminescence detection system was found, and the original detection sensitivity was increased by one order of magnitude.
The detection technology of three types of pesticide auxiliaries in agricultural products has been established, and the multi-residue confirmation detection methods such as plant growth regulators, herbicides, environmental pollutants and prohibited additives in China's agricultural products have been constructed, and the multi-residue confirmation detection
of more than 300 hazard factors in five categories has been realized.
