Water is an essential resource for all living organisms. The continuous andincreasing use of pesticides in agricultural and urban activities results inthe pollution of water resources and represents an environmental risk. Tocontrol and reduce pesticide pollution, reliable multi-residue methods for thedetection of these compounds in water are needed. In this context, the presentwork aimed at providing an analytical method for the simultaneous determinationof trace levels of 51 target pesticides in water and applying it to theinvestigation of target pesticides in two agriculture-impacted areas ofinterest. The method developed, based on an isotopic dilution approach andon-line solid-phase extraction-liquid chromatography-tandem mass spectrometry,is fast, simple, and to a large extent automated, and allows the analysis ofmost of the target compounds in compliance with European regulations. Furtherapplication of the method to the analysis of selected water samples collectedat the lowest stretches of the two largest river basins of Catalonia (NESpain), Llobregat and Ter, revealed the presence of a wide suite of pesticides,and some of them at concentrations above the water quality standards (irgaroland dichlorvos) or the acceptable method detection limits (methiocarb,imidacloprid, and thiacloprid), in the Llobregat, and much cleaner waters inthe Ter River basin. Risk assessment of the pesticide concentrations measuredin the Llobregat indicated high risk due to the presence of irgarol,dichlorvos, methiocarb, azinphos ethyl, imidacloprid, and diflufenican (hazardquotient (HQ) values>10), and an only moderate potential risk in the Ter Riverassociated to the occurrence of bentazone and irgarol (HQ>1).
