The EPA and companies responsible for the waste in this area, which includes a three-mile section of Portage Creek as well as part of the Kalamazoo River, into which it flows, are currently involved in an effort to reduce the amount of toxic waste at the site, which is contaminated by PCBs (polychlorinated biphenyls) from paper mills and other factories.〔("Allied Paper, Inc./ Portage Creek/Kalamazoo River." Environmental Protection Agency. 30 Sep. 2008. EPA. 10 Oct. 2008. )〕 ==History== After the Industrial Revolution, many paper mills that sprouted up along the Kalamazoo River were found to be the cause of PCB contamination.〔The publication in a 1953 issue of Life Magazine of a photograph depicting dead carp floating in the Kalamazoo River drew national attention to the public interest.〔("About Our River." Bringing Back the Kalamazoo River. 2007. Kalamazoo Watershed Council. 16 Oct. 2008 )〕 The Kalamazoo Superfund site was added to the National Priorities List on August 30, 1990, and the First Cleanup Action began in late 1990.〔 Between 1990 and 2000, under an agreement with the EPA and the State of Michigan, several of the current and past owners of plants that had been responsible for the contamination investigated the Portage Creek site.〔(【引用サイトリンク】url=http://www.epa.gov/region5/cleanup/kalproject/pdfs/kalproject-fs-201205.pdf )〕 PCB Contamination Polychlorinated biphenyls constitute a wide array of now-banned organic chemicals with a variety of industrial applications. At the Kalamazoo River site, most PCBs are a result of the recycling of carbonless copy paper during the 1970s, the waste products from which were dumped into the river. PCBs were produced from 1929 to 1979, when they were banned by the Toxic Substances Control Act.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Kalamazoo Superfund Site」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
