Physicochemical analysis detected heavy metals at concentrations insufficient to account for the observed acute toxicity. The graduated pH and aeration manipulations identified the prominent toxicity of ammonia. Based on joint toxicity with additive effects of unionized ammonia and ammonium ions, the unionized ammonia toxicity () was calculated as 3.3 ppm, and the toxicity of ammonium ions () was calculated as 222 ppm. Then, the contribution of ammonia toxicity in the landfill leachate toxicity was calculated as 58.7 vol% of the total toxicity in the landfill leachate. Other specific toxicants masked by ammonia's toxicity were detected. Contribution rate of the toxicants other than by ammonia was 41.3 vol% of the total toxicity of the landfill leachate.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380016865654780290","@type":"Researcher","foaf:name":[{"@value":"Takuya Osada"}],"jpcoar:affiliationName":[{"@value":"Department of Chemical Science and Engineering, Tokyo National College of Technology, 1220-2 Kunugida-Machi, Hachioji, Tokyo 193-0997, Japan"}]},{"@id":"https://cir.nii.ac.jp/crid/1380016865654780416","@type":"Researcher","foaf:name":[{"@value":"Keisuke Nemoto"}],"jpcoar:affiliationName":[{"@value":"Department of Chemical Science and Engineering, Tokyo National College of Technology, 1220-2 Kunugida-Machi, Hachioji, Tokyo 193-0997, Japan"}]},{"@id":"https://cir.nii.ac.jp/crid/1380016865654780291","@type":"Researcher","foaf:name":[{"@value":"Hiroki Nakanishi"}],"jpcoar:affiliationName":[{"@value":"Department of Chemical Science and Engineering, Tokyo National College of Technology, 1220-2 Kunugida-Machi, Hachioji, Tokyo 193-0997, Japan"}]},{"@id":"https://cir.nii.ac.jp/crid/1380016865654780417","@type":"Researcher","foaf:name":[{"@value":"Ayumi Hatano"}],"jpcoar:affiliationName":[{"@value":"Department of Chemical Science and Engineering, Tokyo National College of Technology, 1220-2 Kunugida-Machi, Hachioji, Tokyo 193-0997, Japan"}]},{"@id":"https://cir.nii.ac.jp/crid/1380016865654780418","@type":"Researcher","foaf:name":[{"@value":"Ryo Shoji"}],"jpcoar:affiliationName":[{"@value":"Department of Chemical Science and Engineering, Tokyo National College of Technology, 1220-2 Kunugida-Machi, Hachioji, Tokyo 193-0997, Japan"}]},{"@id":"https://cir.nii.ac.jp/crid/1380016865654780288","@type":"Researcher","foaf:name":[{"@value":"Tomohiro Naruoka"}],"jpcoar:affiliationName":[{"@value":"Research Center for Material Cycles and Waste Management, National Institute for Environmental Studies, Onogawa 16-2, Tsukuba, Ibaraki 305-8506, Japan"}]},{"@id":"https://cir.nii.ac.jp/crid/1380016865654780289","@type":"Researcher","foaf:name":[{"@value":"Masato Yamada"}],"jpcoar:affiliationName":[{"@value":"Research Center for Material Cycles and Waste Management, National Institute for Environmental Studies, Onogawa 16-2, Tsukuba, Ibaraki 305-8506, Japan"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"20906188"},{"@type":"EISSN","@value":"20906196"}],"prism:publicationName":[{"@value":"ISRN Toxicology"}],"dc:publisher":[{"@value":"Wiley"}],"prism:publicationDate":"2011-09-28","prism:volume":"2011","prism:startingPage":"1","prism:endingPage":"6"},"reviewed":"false","dcterms:accessRights":"http://purl.org/coar/access_right/c_abf2","dc:rights":["http://creativecommons.org/licenses/by/3.0/"],"url":[{"@id":"http://downloads.hindawi.com/archive/2011/954626.pdf"},{"@id":"http://downloads.hindawi.com/archive/2011/954626.xml"}],"createdAt":"2011-09-28","modifiedAt":"2025-03-12","foaf:topic":[{"@id":"https://cir.nii.ac.jp/all?q=Review%20Article","dc:title":"Review Article"}],"relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1390854957926787072","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Development of Method Determining Tetramethylammonium Hydroxide and Tetramethylammonium Salts in Industrial Wastewater by LC-MS/MS"},{"@language":"ja","@value":"LC-MS/MSによる事業場排水中の水酸化テトラメチルアンモニウムとテトラメチルアンモニウム塩類の測定法開発"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.5402/2011/954626"},{"@type":"OPENAIRE","@value":"doi_dedup___::9b4194da1cf0dfdb7ae4ffd4fb48e8fc"},{"@type":"CROSSREF","@value":"10.2965/jswe.45.115_references_DOI_kLyXWvNrNyiXk2V0lVhPa6GGZS"}]}
