Multi-residue analysis of pyrethroids in soil and sediment using QuEChERS by LC/MS/MS

Pytrethroids are one of the most widely used commercial household insecticides in agricultural or non-agricultural application sites. Synthetic pyrethroids are poorly water-soluble, but are strongly adsorbed to soil, therefore these compounds are increasingly being found in soil or sediments. Recently, soil and sediment contamination by pyrethroids has been detected in both urban and agricultural area, and it's becoming a global concern due to the influence on the insects and aquatic invertebrates.
Therefore, quick, high-sensitive and universal analysis methods are required. The analysis of pyrethroids is typically performed by GC or GC/MS because of their hydrophobicity. In this study, we report the development of a simultaneous analysis technique for trace amounts of pyrethroids by LC/MS/MS.
