Abstract

Olive mill wastewater (OMW), which causes environmental problems in aquatic ecosystems in our country and especially in Mediterranean countries, has negative effects on aquatic organisms. In this study, acute effects of OMW were experimentally investigated on three freshwater snails; Potamopyrgus antipodarum, Melanopsis buccinoidea, and Theodoxus sp. Freshwater gastropods selected as the experiment organism were transferred from their natural habitat to the laboratory and their adaptations were provided as separate taxa. OMW that was used as the active substance in various ratios for this experiment was obtained from a company that produces olive oil in Çanakkale Province. To determine the acute effects of OMW on the target organisms, OMW was introduced in different ratios into the test tanks which have twenty individuals. According to the findings, LC50 values of the OMW on Potamopyrgus antipodarum (for 96 hours), Melanopsis buccinoidea (for 48 hours), and Theodoxus sp. (for 48 hours) were calculated 9.51%, 6.40%, and 5.08%, respectively.
