Rapid and sensitive SPME-GC–MS/MS method to analyze 14 multiclass UV filters in water. Derivatization carried out in the own vial where the extraction takes place. The main parameters affecting the extraction were optimized by multivariate analysis. 28 water samples were analyzed and 11 out of the 14 target UV filters were detected. 2EHMC, a potential new priority pollutant, was detected in 79% of the samples.
