Monitoring of Pesticides in Drinking, Surface and Ground Water of Cyprus by Liquid-Liquid and Solid Phase Extraction in Combination with GC/MS and UPLC/MS/MS

Abstract

Pesticides having different structures and biological activities are widely used for agricultural and non-agricultural purposes throughout the world. Monitoring of pesticides in water contribute to the protection of human health and the protection of environment also. Analysis of a big number of water samples each year is revealed a clear image for pollution by pesticides. Twenty-four pesticides are monitored in drinking, surface and ground waters of Cyprus according to the European legislation. During the last 4 years (2013-2016) 2860 samples were analysing using two different techniques of extraction and determination. Pesticides were separated at two groups according to their polarity and stability and determined using GC/MS and UPLC/MS/MS. The limit of quantification is 0.01 μg/L for those determined with UPLC/MS/MS and 0.01 - 0.03 μg/L for those determined with GC/MS...
