The "Drops" practice team from School of Chemistry and Chemical Engineering of Xiamen University carried out a practical investigation on the phenomenon of pesticide residues in fruits and vegetables with the combination of professional knowledge. Through the investigation and interview of citizens from different backgrounds, it is found that there are some doubts about their understanding of pesticide residues and the removal methods used daily. On the basis of a large number of literature research, the current detection methods of pesticide residues were summarized, and the methods suitable for this practice were selected and optimized. The method of partial removal of agricultural residues was tested experimentally and some suggestions were given according to the results. This practice will apply professional knowledge to the practice, training and improving the students' practical ability and comprehensive quality.

Key words: Food safety, Pesticide residues, Practice research
