A simultaneous analysis for thiuram, iprodione and bensulide in environmental water was performed by the procedures including solid-phase extraction and high performance liquid chromatography (HPLC). To 1000 ml of sample water, two grams of ethylenediamine tetraascetic acid disodium dihydrate (EDTA・2Na・2H_2O) was added. The sample solution was passed through Sep-Pak ENVtC_<18> cartridge which was previously washed with acetonitrile containing 50 mM EDTA・2 Na. The cartridge was washed with acetonitrile-H_2O (3 : 7) and the sample was eluted with acetonitrile. The eluant was analysed by HPLC on a column of C_<18>-bonded silica gel (Nucleosil 120-5C18) with acetonitrile-methanol (60 : 40) as mobile phase. The recoveries of thiuram, iprodione and bensulide added to environmental waters were 91-96%, 101-105% and 100-104%, respectively. Addition of EDTA・2Na to the sample water was effective for analysing thiuram.
