GC-MS method is proposed for determination of atrazine in water. The limit of detection (LOD) is 0.0050 μg L-1 and quantification is possible in the range 0.011 to 1.84 μg L-1. The method was used for analysis of surface water sampled from Silistra and from Rousse, on the Lower Danube, over a two-year period. The concentrations of atrazine in the samples were from 0.389 to 0.673 μg L-1, RSD 4.25%. The quanti-tative data obtained were processed statistically and showed seasonal and geographic changes in atrazine concentration. Important conclusions about the current status of the pollution were obtained from statistical and compa-rative analysis, as were other trends in the contamination of surface waters with atrazine.
