Chemical and biological properties of 8 samples of drilling wastes from the long-term storage sites in the areas of oil various chemical composition (content of petroleum contaminants 0.6-27.6 wt. %, content of toxic heavy metals 117-730 mg/kg d.m.), and a low susceptibility to biodegradation (within the range of 11-58% during the 60-days experiment) were determined. I was found that samples having higher aliphatic/aromatic hydrocarbons ratio were more susceptible to biodegradation. Considering the high contents of the petroleum contaminants, in which the polar component i.e. resins and asphaltenes, are present, all the tested wastes a treat hazard to the environment. The components of potential mutagenic and carcinogenic properties have been found only in the single samples from a wastes series before and after biodegradation.
