Abstract
The presence of 16 of the most widely used pesticides in southern Italy(plus atrazine, the use of which is currently restricted in Europe) has been monitored in ten surface waters of the Calabria Region. The analytes were extracted from water by off-line solid-phase extraction with a Carbograph cartridge. 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%. Confirmatory analysis was performed by HPLC coupled with ion-spray mass spectrometry (LC-ESI-MS).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
