Abstract: Oily wastes are considered as one of the most hazardous waste types. Additionally to petroleum components, they can contain radioactive elements. This study aimed to estimate the toxicity of four raw and two treated waste samples obtained from petroleum production yard. Eight elutriate bioassays using plants (Raphanus sativus and algae Scenedesmus quadricauda), crustacean (Daphnia magna and Thamnocephalus platyurus), rotifer (Brachionus calyciflorus), protozoa (Paramecium caudatum) and bacteria (Bacillus pumilus and luminescent commercial strain) were used. Two contact bioassays based on R. sativus and B. pumilus were applied. Total petroleum hydrocarbons (TPH) content and activity concentrations of radium, thorium and potassium were determined.

Keywords: TENORM; oily waste; toxicity; elutriate bioassays; waste management; petroleum production; total petroleum hydrocarbons; TPH content; radium; thorium; potassium.
