Abstract
The extensive use of the broad range of pesticides employed to maintain golf courses has prompted serious environmental concerns in Japan since courses tend to be located in mountainous regions, often in close proximity to virgin water sources. Since older empirical methods are not appropriate for substance identification and determination of substance concentrations on the ppb order, gas chromatographyquadrupole mass spectrometry (GC/QPMS) can be employed. A simple extraction of 500 ml of drainage pond water gives a sample which allows identification of pesticides with quantitation on the ppb order using selected ion monitoring (SIM). A sample of drainage pond water from a golf course revealed fenitrothion, funitrothion, chlorothalonil and isoprothiolane in concentrations of 120.1, 20.7, 45.6 and 130.5 ppb, respectively.
