Analyses of Agricultural Chemicals in Golf Courses Using LC/MS/MS

Introduction

In order to prevent water pollution by agricultural chemicals used in golf courses, the Guideline for the Prevention of Water Pollution and Damage to Aquatic Animals and Plants by Agricultural Chemicals Used in Golf Courses (the Guideline) was established by the Ministry of the Environment (MOE) of Japan (Final amendment: Nov. 30, 2018 (No. 1811301, Issued by the Soil Environment Management Division, Environment Management Bureau, MOE)). The Guideline defines the concentration limits in drainage water for the agricultural chemicals causing water pollution as ten times greater than the registered reference values. The concentrations in drainage water at the drainage port of golf courses must not exceed the values listed in the appendix (the guideline values). The latest registered reference values are indicated on the website of the MOE. The standard analysis methods for drainage water are provided in an addendum of the Guideline: 51 methods are listed under " Standard Analysis Methods for Drainage Water (Individual Analysis)" and six methods are listed under " Standard Analysis Methods for Drainage Water (Simultaneous Multi-Component Analysis)". This article introduces individual analyses of seven agricultural chemicals (1. -10 Bensultap, 2. -21 Thiophanate- methyl, 3. -23 Validamycin, 4. -24 Hydroxyisoxazole (Hymexazol), 5. -27 Benomyl, 6. -50 MCPA Isopropylamine Salt and MCPA Sodium Salt, 7. -51 Trinexapac-ethyl), and a simultaneous multi-component analysis of 44 agricultural chemicals according to -1, which were conducted using LC/MS/MS.
