The data compiled during five-year-long investigation on the influence of drilling water and crude oil on specific composition, number and structure of the communities of free-living soil ciliates is presented. The vertical distribution of ciliates and their colonizing potential in the sterile soil monoliths placed in clean and polluted soils was studied on the basis of their survival and physiological responses. | Turk J Biol 24 (2000) 309–320 © TÜBİTAK Freeliving Ciliates of Pure and Soils Polluted by Constituents of Oil Lifting at Apsheron Peninsula İlham ALEKPEROV Baku Institute of Zoology Acad of Sciences of Azerbaijan, 1128, BL 504, Baku, AZERBAIJAN Received: 16.10.1996 Abstract: The data compiled during five-year-long investigation on the influence of drilling water and crude oil on specific composition, number and structure of the communities of free-living soil ciliates is presented. The vertical distribution of ciliates and their colonizing potential in the sterile soil monoliths placed in clean and polluted soils was studied on the basis of their survival and physiological responses. The changes in certain ciliate species were demonstrated by biotesting of the influence of various concentrations of drillinig water, crude oil and drillinig muds on these ciliates. Key Words: Ciliates, soils, biotest, oil pollution. Abşeron Yarımadasının Petrol ve Petrol Ürünleri ile Kirlenmiş ve Kirlenmemiş Topraklarında Serbest Yaşayan Siliatları Özet: Bu çalışmada serbest yaşayan Siliatların tür terkibine, sayısına ve onların topluluklarının kuruluşuna acı sularının, şlamının ve ham petrolun 5 yıl arzinda incelenmiş bulgulardan bahsediliyor. Silatiatların şaguli istigametde paylanması, kirlenmiş ve kirlenmemiş topraklarda yerleşdirilmiş steril toprak monolitlerinde colonization prosesinin sonuçları verilmiştir. Bazı Siliat türlerinin yaşama kabiliyetinin ve fizyolojik parametrelerininin değişiklenmesini incelemekle, acı sularının, şlamının ve ham petrol çeşitli konsantrasyonlarının toksik etkisi derecesi araştırılmıştır. Anahtar Sözcükler: Siliatlar, toprak, biyotest, petrol kirlenmesi. Introduction The problem of environmental pollution from oil and other constituents of oil lifting is of great importance to Azerbaijan. In addition to the almost complete western littoral regions of the Caspian Sea, which is already significantly polluted, the soils of Azerbaijani Republic are
