| The article has two parts. Firstly,a capillary gas chromatography is found to analyze organic phosphorus pesticide multifarious remains in tea, wich is dichlorvos, phoxim, dimethoate, fenitrothion, malathion and phosmet. Research the optimum conditions and the optimum project of pretreatment, do elective examinations for the market tea. Recoveries obtained are in the range of 83.1% to 98.8%. The relative standard deviations are in the range of 1.7% to 3.3%. And their detection limits are found in the rage of 1.6×10-13g/s to 6.0×10-14g/s. Secondly, it is reported that the HG-AFS determination of arsenic is used in single use and degradable lunch contaainer and drinking set wich pretreated by migration. Choose the optimum conditions, there is a linear relationship between the fluorescence intensity and arsenic concentration in the range of 0 to 200 ng·ml-1, and its detection limit is found to be 0.068ng·ml-1. Recoveries obtained by the standard addition method are in the range of 88.4% to 99.2%. This method had been largely applied and results were obtained.Tian Yong(environmental engineering) Directed by prof. Feng Hui...
