The levels of persistent organic pollutants (POPs) from industrial by-products were determined in beach sand and marine sediments from different sites along the Jordanian coast of the Gulf of Aqaba. Seventeen polychlorinated dibenzo-p-dioxins and polychlorinated dibenzo-p-furans (PCDD/Fs) compounds were identified. Automatic Soxhlet (Soxtec) extraction method was used for PCDD/Fs extractions using toluene as a solvent. Pre-washed multilayer silica gel column was used for cleanup step. Samples were analyzed using high-resolution gas chromatography and mass spectroscopy detector (HRGC–MS). Low levels of POPs were found in all sand and sediment samples. Concentrations of PCDD/Fs ranged between 3.91 and 8.91 ng kg−1 dw with an average of 6.49 ng kg−1 dw for beach sand samples and between 6.560 and 45.95 ng kg−1 dw with an average of 28.70 ng kg−1 dw for marine sediment samples. Concentrations of PCDD/Fs for soil and sediment were mostly less than other sites worldwide. PCDD/Fs concentrations measured in this study can be considered as a baseline for future monitoring and control of PCDD/Fs as requested by Stockholm Convention.
