An analytical method that can allow one to determine simultaneously chosen organic micropollutants has been developed to measure their concentrations in water. Standard mixture of 16 polycyclic aromatic hydrocarbons (PAH) and nine polychlorinated biphenyls (PCB) was added to distilled water in a specific amount. The solid phase extraction (SPE) method was applied. Isopropyl alcohol and methanol were used to precondition SPE extraction columns. PAH and PCB were eluted from the column fillings using dichloromethane. Extracts were condensed to a volume of 2 mL. Prepared samples were analyzed with the use of gas chromatography and mass spectrometry. The achieved percent recovery of PAH was from around 7% in the case of chrysene to 100% in the case of naphthalene. The achieved percent recovery of PCB was from about 51% in the case of PCB 101 to 92% in the case of PCB 156.
