Screening for Pyrethroid Insecticides in Sediment Samples by GC-MS/MS

A simple screening method for pyrethroid insecticides in sediment samples is described in this application note. Electron impact ionization (EI) with tandem MS/MS in combination with programmed temperature vaporization injection (PTV) were used in order to obtain excellent specificity and low limits of detection of pyrethroids in river and lake sediments.
