Guo, Jingheng; Wang, Fushun; Vogt, Rolf David; Zhang, Yuhang; Liu, Cong-Qaing (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)Chemical weathering is a fundamental geochemical process regulating the atmosphere-land-ocean fluxes and earth’s climate. It is under natural conditions driven primarily by weak carbonic acid that originates from atmosphere ...

Gundersen, Cathrine Brecke; Andersen, Tom; Lindahl, Sofia; Linke, Dirk; Vogt, Rolf David (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)Currently the most promising method for capturing anthropogenic produced carbon dioxide (CO2) from suitable point sources is the technique using amines in Post-combustion CO2 Capture (PCC). However, the use of amine is ...

Orderud, Geir; Vogt, Rolf David; Andersen, Tom; Luo, Jing (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)Most of China’s surface waters are undergoing anthropogenic eutrophication, mainly due to leaching of phosphorus (P) from both sewage and agriculture. This is causing quality deterioration in their scarce water resources. ...

Mohr, Christian Wilhelm; Vogt, Rolf David; Røyset, Oddvar; Andersen, Tom; Parekh, Neha (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)Long-term laborious and thus costly monitoring of phosphorus (P) fractions is required in order to provide reasonable estimates of the levels of bioavailable phosphorus for eutrophication studies. A practical solution to ...

Nipen, Maja; Vogt, Rolf David; Bohlin-Nizzetto, Pernilla; Borgå, Katrine; Mwakalapa, Eliezer Brown; Borgen, Anders; Schlabach, Martin; Christensen, Guttorm N; Mmochi, Aviti John; Breivik, Knut (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Temporal trends of industrial organic contaminants can show how environmental burdens respond to changes in production, regulation, and other anthropogenic and environmental factors. Numerous studies have documented such ...

Han, Xiaoxin; Wang, Shiyu; Yu, Xue; Vogt, Rolf David; Feng, Jianfeng; Zhai, Lifang; Ma, Weiqi; Zhu, Lin; Lu, Xueqiang (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Due to its small size, large specific surface area and hydrophobicity, microplastics, and the adsorbed contaminants may together cause potential negative effects on ecosystems and human beings. In this study, kinetics and ...

Zhou, Bin; Vogt, Rolf David; Lu, Xueqiang; Yang, Xiaoguang; Lü, Changwei; Mohr, Christian W.; Zhu, Liang (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)The total level of phosphorus (P) and the distribution of P pools in the topsoil are significantly affected by the excessive application of mineral and organic fertilizers connected with intensive agriculture. This leads ...

Nipen, Maja; Jørgensen, Susanne Jøntvedt; Bohlin-Nizzetto, Pernilla; Borgå, Katrine; Breivik, Knut; Mmochi, Aviti J; Mwakalapa, Eliezer; Quant, M. Isabel; Schlabach, Martin; Vogt, Rolf David; Wania, Frank (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)There are large knowledge gaps concerning concentrations, sources, emissions, and spatial trends of mercury (Hg) in the atmosphere in developing regions of the Southern Hemisphere, particularly in urban areas. Filling these ...

Łukawska-Matuszewska, Katarzyna; Vogt, Rolf David; Xie, Ruikai (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)Spatial variations in phosphorus (P) fractionation, sediment geochemistry, and sorptive properties for P are assessed to test the hypothesis that these sediment properties vary within the lake and are governed by different ...
-
Zhou, Bin; Fu, Xujin; Wu, Benjun; He, Jia; Vogt, Rolf David; Yu, Dan; Yue, Fu-Jun; Chai, Man (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Following successful abatement of external nutrient sources, one must shift the focus to the role of phosphorus (P) release from sediment. This enables us to better assess the causes for sustained eutrophication in freshwater ...

Li, Xue; Han, Xiaoxin; Vogt, Rolf David; Zhou, Jiaying; Zheng, Boyang; Zhang, Yan; Tu, Jianbo; Song, Yutong; Lu, Xueqiang (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2022)Bohai Bay, a typical semi-enclosed bay, is close to the Beijing-Tianjin-Hebei Region, the economic center of north China. The release of emerging contaminants was considerably increasing with the fast urbanization and ...

Wang, Shiyu; Vogt, Rolf David; Carstensen, Jacob; Lin, Yan; Feng, Jianfeng; Lu, Xueqiang (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2021)The flux of terrestrial dissolved inorganic phosphorous (DIP, i.e. PO43−) via rivers into coastal seas is usually calculated by simply multiplying its concentration with the corresponding water flow at the river mouth. ...
