In order to evaluate their hygienic risk, wood samples from sleepers (railroad cross ties) impregnated with coal tar creosote were taken from playgrounds and investigated for hazardous compounds. The samples were extracted with ether, and acid-base-neutral separations were made on the creosote extracts. Water-soluble compounds were also isolated. All the fractions were investigated by capillary gas chromatography-mass spectrometry. Besides phenols in the acidic fractions and N-heterocyclic polynuclear aromatic hydrocarbons (PAH) in the basic fractions, high amounts of neutral PAH and also, in several samples high levels of carcinogenic and cocarcinogenic PAH were determined.
