Oil pollutants in alluvial sediments - influence of the intensity of contact with ground waters on the effect of microorganisms
Naftni zagađivači u aluvijalnim sedimentima - uticaj intenziteta kontakta sa podzemnim vodama na dejstvo mikroorganizama
Abstract
The influence of the intensity of interaction between oil pollutants and ground waters in alluvial sediments on the effect of microbial activity was investigated in this work. The study was based on a comparison of detailed analyses of two fractions of an oil pollutant originating from a Danube alluvial formation near the Pancevo Oil Refinery: fraction 1. separated from the aqueous layer by decantation. presumed to have been in less intensive interaction with water. and fraction 2. isolated from the aqueous emulsion by extraction with chloroform. presumed to have been in stronger interaction with water, Both fractions were shown to originate from the same type of oil pollutant. Nevertheless. significant compositional differences between the two fractions were observed. A significantly pronounced domination of even carbon number homologues of C-18-C-24 n-alkanes in fraction 2. atypical for crude oil pollutants, compared to the corresponding distribution observed in fraction 1, suggested... a more intense activity. i.e., a much better effect of microorganisms in direct contact with the oil pollutant within the aqueous environment. The identification of even carbon number C-14-C-18 n-alcohols and C-14-C-18 fatty acids, as well as cholesterol, in fraction 2, suggested that microorganisms of the algal type in non-photosynthetic conditions were most probably responsible for the mentioned microbial processes.
Procenjivan je uticaj intenziteta interakcije između naftnog zagađivača i podzemne vode aluvijalne formacije na intenzitet mikrobiološkog dejstva. U tom cilju poređani su sastavi dve frakcije naftnog zagađivača iz jednog pijezometra (krug Rafinerije nafte Pančevo, aluvijalna formacija reke Dunav): frakcije 1, odvojene od vode dekantovanjem (slabija interakcija sa vodom) i frakcije 2, izdvojene iz vode ekstrakcijom (jača interakcija sa vodom). Dokazano je da obe frakcije vode poreklo od istog naftnog zagađivača. Znatno veća obilnost normalnih alkana sa izrazitom dominacijom parnih homologa (C18–C24) u frakciji 2 nego u frakciji 1 ukazuje na intenzivniju aktivnost mikroorganizama u vodenoj sredini. Alkoholi normalnog niza sa parnim brojem ugljenikovih atoma (C14–C20), holesterol i masne kiseline normalnog niza sa parnim brojem ugljenikovih atoma (C14–C18) u frakciji 2 dokaz su da su za mikrobilošku aktivnost u nefotosintetičkim uslovima odgovorni mikroorganizmi algalnog tipa.
