A sensitive analytical method has been developed for the determination of polycyclic aromatic hydrocarbons in water, including priority pollutants according to the European Union, by gas chromatography coupled to triple quadrupole tandem mass spectrometry (GC‐QqQ‐MS/MS). The sample treatment was based on a solid‐phase extraction method which was validated in four different types of water: seawater, drinking water, untreated inland water and wastewater according to CD 2002/657/EC and SANTE/11813/2017 guidelines. Obtained recovery, studied at three concentration levels (1.7, 5.6 and 25.0 ng/L), was in the range 77–108%. Precision values were ≤ 17% and 22% for intra‐day and inter‐day precision, respectively. Linearity was studied in the range 1.4‐100 ng/L, and the obtained determination coefficients (R2) were ≥ 0.9962. Limits of detection were in the range from 1.0 to 3.0 ng/L, whereas limits of quantification were established from 1.4 to 5.0 ng/L. The validated method was successfully accredited according to ISO/IEC 17025 international standard (including calculation of uncertainty) and applied to routine analysis of real water samples.
