Little information is available on the occurrence and fate of persistent organic pollutants in lakes of Turkey. The present study was performed as a first step to assess the occurrence, spatial distribution, and potential sources of polychlorinated biphenyls (PCBs) in surface sediments of Lake Eymir located in a special protection area. I 41PCB pound concentrations range from 1.09 to 2.33 ng g(-1) in 62 sediment samples collected from the lake. The spatial homogeneity of the PCBs along the whole lake suggests the resuspension or redistribution of historic PCB contamination. A chemical mass balance (CMB) receptor model was used to identify the possible sources of PCBs, for which a limited number of congeners are available for modeling purposes. Results indicated Clophen A60 to be the major PCB source in lake sediments. CMB analysis also showed the importance of a number of compounds used for the assessment of source contributions.

Exposure to a microplastic mixture is altering the life traits and is causing deformities in the non-biting midge Chironomus riparius Meigen (1804) Stankovic, Jelena; Milosevic, Djuradj; Savic-Zdrakovic, Dimitrija; Yalçın, Gülce; Yildiz, Dilvin; Beklioğlu, Meryem; Jovanovic, Boris (Elsevier BV, 2020-07-01) The effect of microplastics (MP) exposure on the chironomid species Chironomus riparius Meigen, 1804 was investigated using the OECD sediment and water toxicity test. Chironomid larvae were exposed to an environmentally relevant low microplastics concentration (LC), a high microplastics concentration (HC) and a control (C). The LC was 0.007 g m(-2) on the water surface + 2 g m(-3) in the water column + 8 g m(-2) in the sediment, and the HC was 10 X higher than this for each exposure. The size of the majorit...
Biofilms attached to Myriophyllum spicatum play a dominant role in nitrogen removal in constructed wetland mesocosms with submersed macrophytes: Evidence from N-15 tracking, nitrogen budgets and metagenomics analyses Mu, Xiaoying; Lv, Xiaoyang; Liu, Wei; Qiu, Changhao; Ma, Yu; Zhang, Songhe; Jeppesen, Erik (Elsevier BV, 2020-11-01) The mechanisms behind nitrogen removal by the submersed macrophyte-biofilm complex in wetlands remain to be fully elucidated. This study investigated the role of Myriophyllum spicatum and the biofilm on their leaves in nitrogen removal in mesocosm experiments. N-15 tracking showed that 61.9% and 30% of the N-15, respectively, was removed from the system and assimilated by the macrophyte-biofilm complex after loading with 5.4 mg L-1 N-15 labelled NH4+ for 17 days. Nitrogen budget results showed that about 0....
Water column nutrient concentrations are related to excretion by benthic invertebrates in Lake Taihu, China Peng, Kai; Qin, Boqiang; Cai, Yongjiu; Gong, Zhijun; Jeppesen, Erik (Elsevier BV, 2020-06-01) Internal release of nutrients is an important contributor to the nutrient dynamics in shallow eutrophic lakes. Zoobenthic organisms may contribute to this release by excreting nutrients to the overlaying water. Based on experiments and using results from previous experimental studies as well as field monitoring density data from 2007 to 2017, we calculated the annual and seasonal nutrient excretions of the two most common macroinvertebrates (Corbicula fluminea and Limnodrilus hoffmeisteri) in Lake Taihu, Ch...
Characterization of aldrin epoxidation in flathead mullet (Mugil cephalus) liver microsomes: Involvement of CYP3A BOZCAARMUTLU, AZRA; Turna, S.; Erden, C. Sapmaz; Yenisoy-Karakas, S.; Arinc, E. (2011-08-28) Toxic organochlorine pesticides, aldrin and its metabolite dieldrin, have been reported to contaminate the aquatic environment highly. In the present study, epoxidation reaction of aldrin to dieldrin was studied in mullet liver microsomes and contribution of cytochrome P450 isozyme(s) was determined by using specific cytochrome P450 inhibitors and substrate. Flathead mullet samples (Mugil cephalus) were caught from the West Black Sea Region of Turkey. Fish liver microsomes were prepared by differential cent...
Characterization of SDS-degrading Delftia acidovorans and in situ monitoring of its temporal succession in SDS-contaminated surface waters YILMAZ, Fadime; İçgen, Bülent (Springer Science and Business Media LLC, 2014-06-01) Incomplete removal of sodium dodecyl sulfate (SDS) in wastewater treatment plants may result in SDS residues escaping and finding their way into receiving water bodies like rivers, lakes, and sea. Introduction of effective microorganisms into the aerobic treatment facilities can reduce unpleasant by-products and SDS residues. Selecting effective microorganisms for SDS treatment is a big challenge. Current study reports the isolation, identification, and in situ monitoring of an effective SDS-degrading isola...
