A rapid and simple method for the simultaneous determination of trace amounts of six triazine herbicides (prometryn, propazine, ametryn, atrazine, simetryn, simazine) in water was investigated. A 200-500 ml volume of water was pre-concentrated by passage at a flow-rate of about 15 ml/min through Sep Pak C_<18> cartridge. After washing with 5 ml of hexane, triazine herbicides were eluted with 5 ml of hexane-ethylacetate (80 : 20,v/v). The solvent mixture was concentrated to 1 ml under vacuum at 36-37℃ and analysed by high performance liquid chromatography with UV detection at 220 nm. The limits of detection were 0.05 μg/l in these herbicides. The coefficients of variation for each herbicide were less than 5%. Simazine was detected in water sampled from two ponds at concentrations of 0.7 and 13.4 μg/l, respectively.
