摘要：

Sampling of 5 liters of river Rhone water in each of seven stations located at the Camargue region took place in November 1990 during an oceanographic cruise (Dypole 7) organized within the French scientific programme GDR-ICO (Groupement De Recherche, Interface Continent Ocean, CNRS). After sampling was completed, water samples were filtered through fiberglass filters and two fractions corresponding to dissolved and particulate matter were obtained. Dichloromethane was used for the liquid-liquid extraction of chlorotriazines dissolved in water with further quantitation by selected ion monitoring (SIM) gas chromatography-mass spectrometry (GC-MS). Concentrations of atrazine in the range of 12-30 ng/l and 1 ng/l in the dissolved and suspended phase, respectively, were found. Such levels were compared with previously reported data from other rivers and have been related with the distribution coefficients K(oc). An estimation of the loss of applied atrazine in the Rhone basin is also reported.
