In this phase of the project it was developed a method for the simultaneous analysis of four neonicotinoid insecticides in surface water, 3 included in the Water Framework Directive. The method involves solid phase extraction of analytes in aqueous samples -SPE followed by separation and quantification by LC-ESIMS/MS. Results of studies and experiments conducted to validate internal systematic method developed in the laboratory certifies that the method is suitable for the purpose achieve the required performance parameters. Detection limits determined for real samples of surface water were in the range 0.3 ng/l acetamiprid and 0.9 ng/l clothianidin and the limits of quantification ranged between 1 ng/l acetamiprid and 3 ng/l clothianidin, thus respecting the Directive 39/2013 recommended method limit (9ng/l).
