N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine(6PPD)is widely used during the process of rubber products in order to prevent the rubber crack caused by ozonation and wear.6PPD can release from tire wear particles to adjacent air,soil and water,or migrate from the food-contact rubber products to food.With unstable characteristic,6PPD is more prone to obtaining other toxic transformation products(6PPD-TPs).They may adversely affect the living environment and food safety,and cause potential health risks.This article summarizes the pretreatment methods of 6PPD and 6PPD-TPs extracted from different matrix samples,such as rubber samples,air dust,soil particles,food and urine sample.High-sensitive detection technologies are also outlined including mass spectrometry,chromatography,chromatography-mass spectrometry,electronic optional resonance method.This study provides technical support for screening 6PPD and 6PPD-TPs,assessing their risk levels of 6PPD and 6PPD-TPs in the environment or food chain,exploring the transformation pathway of 6PPD.
