Abstract:

In order to find a fast, high efficient determination method of Organophosphorus Pesticides (OPPs) residue because OPPs widely used in crops pest control fields in China are causing fearful risks for environment as well as animals and human health, traditional and advanced determination methods were discussed in the study. Based on the spectrum analysis technology combined colorimetric OPPs residue detection experiments in leafy vegetables showed that the absorbance of color reaction between OPPs residues and suitable colorimetric reagents can be distinguished in ppm level of OPPs residues. The detection limit of chlorpyrifos after color reaction with 0.5% Pbcl2 in acetic acid solution is 0.5 ppm. The conclusion was drawn that the detection technologies were diversified, however, a simple, efficient, rapid and nondestructive detection method is lacking and the spectrum analysis technology combined colorimetric can be a new fast and efficient determination method in the future.
