Abstract

Recent studies have indicated that sewer systems and landfills contain polychlorinated biphenyls (PCBs). In this study, 18 surface soil samples were collected from five areas near wastewater treatment plants and landfills to investigate PCB levels. The observed PCB congener numbers and levels in the samples varied. The total PCB values were 5558±2856 pg g-1 dry weight (dw) (261PCB) for the marine outfall of the Buski Pretreatment Plant (Bursa Water and Sewerage Administration), 5386±1627 pg g-1 dw (245PCB) for the Hamitler Landfill Area, 3901±281 pg g-1 dw (235PCB) for the Western Wastewater Treatment Plant, 1824±448 pg g-1 dw (242PCB) for the Yesil Cevre Wastewater Treatment Plant, and 725±220 pg g-1 dw (217PCB) for the Eastern Wastewater Treatment Plant. These results show that the soils near the treatment plants were not completely contaminated by PCBs. At the sampling sites, with the biphenyls between 2 and 7 chlorine molecules and in particular, an abundance of homologue groups with 3, 4, and 5 chlorines were found. Moreover, dioxin-like PCBs (PCB#77, 81, 105, 114, 118, 123, and 126) were detected in all samples.

污水处理厂和垃圾填埋场附近土壤中的多氯联苯(PCB)水平。

最近的研究表明，下水道系统和垃圾填埋场含有多氯联苯(pcb)。在本研究中，从污水处理厂和垃圾填埋场附近的五个地区收集了18个表层土壤样本，以调查多氯联苯水平。样品中观察到的多氯联苯同系物数量和水平各不相同。Buski预处理厂(Bursa水与污水管理局)海洋排放口的总PCB值为5558±2856 pg g-1干重(dw) (261PCB)， hammitler填埋区为5386±1627 pg g-1 dw (245PCB)，西部污水处理厂为3901±281 pg g-1 dw (235PCB)， Yesil Cevre污水处理厂为1824±448 pg g-1 dw (242PCB)，东部污水处理厂为725±220 pg g-1 dw (217PCB)。这些结果表明，处理厂附近的土壤并未完全受到多氯联苯的污染。在2 ~ 7个氯分子的联苯取样点，特别是3、4、5个氯分子的联苯，发现了大量的同源基团。此外，在所有样品中检测到二恶英样多氯联苯(PCB#77、81、105、114、118、123和126)。

期刊介绍： Cessation. Ekoloji is an international journal that focuses on papers that report results from original research on all disciplines engaged in the field of environmental research. We welcome articles that cover the entire spectrum of environmental problems and environmental pollutants, whether chemical, biological or physical. Its coverage extends to all environmentally related issues: air and water pollution, solid waste, noise, recycling, natural resources, ecology and environmental protection. It includes articles on basic and applied environmental pollution research, including environmental engineering and environmental health. All types of pollution are covered, including atmospheric pollutants, detergents, fertilizers, industrial effluents, metals, mining wastes, oil, pesticides, plastics, radioactive materials and sewage. It also includes research papers on ecological and environmental issues such as climate change, biodiversity. The primary criteria for publication are scientific quality and ecological/environmental significance. The journal will be read and contributed to by biologists, applied ecologists, environmental scientists, natural resource specialists, environmental engineers, environmental health specialists, agro-ecologists, veterinaries, agricultural engineers, landscape planners and designers. The journal welcomes full "research papers" and short "research notes", only in the English language.
