Abstract
The presence of 16 of the most widely used pesticides in southern Italy(plu s atrazine, the use of which is currently restricted in Europe) has been mo nitored in ten surface waters of the Calabria Region. The analytes were ext racted from water by off-line solid-phase extraction with a Carbograph cart ridge. Base-neutral, and acid pesticides were then isolated by differential elution. Analyte fractionation and quantification were performed by liquid chromatography (HPLC) with UV detection. Recoveries of analytes from 0.5 L river water (200 ng L-1 spike level) were greater than or equal to 84%. Co nfirmatory analysis was performed by HPLC coupled with ion-spray mass spect rometry (LC-ESI-MS).
