A high-performance liquid chromatographic method for the simultaneous determination of the dinitroaniline herbicides dinitramine, ethalfluralin, trifluralin, pendimethalin and isopropalin in soil and surface water is reported. The soil was extracted with diethyl ether and analysed without any clean-up. The water was analysed after purification and concentration on a C18 cartridge. The average recoveries were in the range 89-104%. The detection limits for the five herbicides were 0.02 mg/kg in dry soil and 0.5 μg/l in surface water.

Abstract
A high-performance liquid chromatographic method for the simultaneous determination of the dinitroaniline herbicides dinitramine, ethalfluralin, trifluralin, pendimethalin and isopropalin in soil and surface water is reported. The soil was extracted with diethyl ether and analysed without any clean-up. The water was analysed after purification and concentration on a C18 cartridge. The average recoveries were in the range 89-104%. The detection limits for the five herbicides were 0.02 mg/kg in dry soil and 0.5 μg/l in surface water.
