Targeted and Un-Targeted Multi-Residue Pesticides Analysis in Food Using Chromatography-Mass Spectrometry and Chemometrics

The overall goal of the project is to use advanced mass spectrometry (MS) techniques and multi-variable statistical tools to investigate multi-residue pesticides in foods, specifically selected fruits and vegetables. The major research goal is to conduct targeted analysis and un-targeted screening of multiple pesticides residues in various kinds of fresh fruits and vegetables.Specific objectives include:The first objective is the evaluation of the impact of household food pre-processing methods on the retention of pesticides residues in vegetables and fruits.The second objective is to develop an ion chromatography-mass spectrometry (IC-MS) based method for the analysis of polar and ionic pesticides in vegetables and fruits.The third objective is the development of efficient methods for comprehensive screening and detection of unknown pesticides residues involving liquid chromatography high resolution mass spectrometry and multi-variable statistics tools.
