Persistent organic pollutants (POPs) are chemicals of global concern due to their potential for long-range transport, persistence in environment, ability to biomagnify and bioaccumulate in ecosystems, as well as their significant negative effects on human health and the environment. In this study, seven targeted polychlorinated byphenils (PCBs, IUPAC Nos. 28, 52, 101, 118, 138, 153, and 180) and the organochlorine pesticides (OCPs) aldrin, dieldrin, endrin, cis-chlordane, transchlordane and oxy-chlordane were quantified in European date mussel (Lithophaga lithophaga L., 1758.) collected from the Sarajevo fish market (Bosnia and Herzegovina). This slow-growing species is widespread along the whole Mediterranean rocky coastline. In Bosnia and Herzegovina (BiH), this species has not been protected by law and the date mussel harvested in the area of the Neum bay (Adriatic sea) could be found in free sale on BiH market. Applied gas chromatography and tissue extraction methods were validated in the NIVA laboratory. Our samples (n=61) were 4.5-8.4 cm in length. Total OCPs in the analyzed samples were low (ranging from non-detectable to 0.419 μg kg-1 w.w.), while Σ7PCBs was ranging from 20.26 to 135.37 μg kg-1 w.w.. PCBs 101, 118, 138 and 153 were dominant congeners in all samples.
