Soil quality — Simultaneous determination of multi-class pesticide residues in soil using gas chromatography-tandem mass spectrometry (GC-MS/MS) and liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis

Апстракт

This standard is intended for the simultaneous analysis of multi-class pesticide residues in soil using GC-MS/MS and LC-MS/MS analysis following the extraction with buffering salts mixture and clean up with the dispersive-soild phase extraction(d-SPE). The number of target analytes is 30(16 of fungicides, 6 of herbicides and 8 of insecticides). This document can be applied to other pesticide residues if its validity is verified. Under the conditions specified in this document, limit of detection as low as 0.05 mg/kg(expressed as dry matter) can be achieved depending on the target analytes.
