RESUMO
In recent years, due to the wide use of pyrethroid insecticides, the impact of pyrethroid insecticides on human health cannot be ignored. Therefore, how to detect pyrethroid insecticide residues in human body accurately and efficiently has become a research hotspot. However, it is difficult to detect pyrethroid insecticides because of its low residues and fast metabolism. Our article reviewed research on the detection of pyrethroid pesticide residues in human biomaterials in recent years, listed various pretreatment methods and detection methods of different biomaterials in detail, as well as summarized reported limits of detection, limits of quantitation, and recoveries of different methods. Finally, we prospected further development in detection methods of pyrethroid pesticide residues in human biomaterials.
