Analysis of Organophosphorus Pesticides in Drinking Water using SPME-GCMS

User Benefits

- The inspection items of Organophosphorus pesticides (Diazinon, Parathion, Phenitrothion, Phenthoate, and EPN) in water quality can be analyzed simultaneously. - The automation of fiber conditioning, pretreatment, and sample injection of SPME is possible using AOC-6000 Plus.

Introduction

Organophosphorus pesticides (OPs) are a class of insecticides based on organophosphorus compounds. It is widely used to control insects on crops in the pesticide market. OPs disrupt the nervous system by ingestion and contact. These are a toxic substance that cause headaches, dizziness, nausea and convulsions. Because of the side effects of these OPs, in Korea, residual standards are also operated in the water quality environment field. In the past, solvent extraction was used as a pretreatment method for water quality testing, but this required excessive solvent use and complex extraction processes. Therefore, the simpler Solid Phase Micro Extraction (SPME)-Gas Chromatography-Mass Spectrometry (ES 05501.5) method has been revised and published by the National Institute of Environmental Research (NIER)[1]. This application news describes the suitability of OPs analysis using SPME automatic injection (AOC-6000 Plus) and GCMS-QP2020 NX for Diazinon, Parathion, Phenitrothion based on the Environmental Standards for drinking water pollution, and Phenthoate, EPN based on the Official test standards for environmental pollution.
