The content of toxic trace elements is an important index to measure the quality of plastic products. For a long time, the determination of toxic trace elements is the focus of third party detection and so on. It is very important to evaluate the accuracy of detection. In this paper, a mathematical model of the uncertainty of trace elements based on regression equation, constant volume and weighing weight is established. The results show that the content of Boron and Lead in the plastic samples is (66.3 ± 5.4) mg/kg and (500 ±30) mg/kg, respectively.
