Pentachlorophenol (PCP) use to be in wide usage as insecticide, fungicide and contactherbicide, but primarily as wood preservative and for industrial purposes. PCP is classified as extremely toxic substance for humans and environment. Systematic investigation of trace amounts PCP in surface water in Serbia has initiated in 2009. For analysis of surface water samples, described in this paper, method using stir bar sorptive extraction (SBSE) after derivatization with acetic acid anhydride followed by thermal desorption (TD) – triple quadrupole gas chromatography mass spectrometer with negative chemical ionization (GC/MS/MS-NCI) analysis was applied. Obtained LOQ of PCP – 6.25x10-4 µg/L is much lower than environmental quality standard (EQS) provided by the Water Frame Directive 2013/31/EU (WFD) for this compound – 0,4 µg/L, what makes this method appropriate for determination of PCP in water samples. Recovery and corresponding RSD of PCP is 82.47%, and 8.7%, respectively. Method showed good linearity over the concentration range of 0.6 - 50 pg/L PCP with coefficient of correlation R2 of 0.999. PCP was detected in all samples and measured amounts were bellow the set EQS values. Minimum ammount of PCP in samples was 5.55 x10-3 µg/L, maximum ammount was 111.74 x10-3 µg/L and the average was 11.62x10-3 µg/L.
