Analysis of Pesticides at Golf Courses using GC/MS

Introduction

In 1990, the Ministry of Health and Welfare and the Environmental Agency designated of pesticides to be used at golf courses and specified guide line values and testing methods for them. Subsequently regulations on water supply and environmental and waste water were further strengthened. At first the Environmental Agency stipulated the method that each pesticides is analyes in dividually using GC. However, in April 1998, new pesticides were added for analysis targets, and simultaneous analysis using GC/MS was presented as the analysis method. (Some of the analyses are conducted by HPLC.) This article introduces examples of measurements by GC/MS, mainly for newly added pesticides acephate, metalaxyl, dithiopyr and pyributicarb.
