The center was identified as the Tianjin International Science and Technology Cooperation Base in December 2018. The Chinese director is Professor Xueqiang Lu and the foreign director is Professor Rolf D Vogt, director of the Center of Biogeochemistry in the Anthropocene at University of Oslo. The core research of the center is the basin’s environmental biogeochemical cycle regulation technology, and the principle research directions are: 1. The fingerprint of environmental geochemistry, 2. The biogeochemical regulation technology of basin’s nitrogen and phosphorus nutrients, 3. The migration, transformation, and regulation technology of pollutants in urban water system, 4. The geochemical technology of natural based solution (NBS). The center aims to induce advanced technologies and experiences from Europe and other countries to establish an international platform for scientific research and talent training in regional or basin pollution control. At present, the center has established good cooperative relations with the University of Oslo, Norway (UiO), the Swedish Environmental Research Institute (IVL), the University of Nagoya (NU), the Laboratory of Water, Environment, and Urban System of University of Paris-Est Créteil Val de Marne (UPEC-LESSU), the University of Birmingham (UoB), The Russian Academy of Sciences' Institute of Biochemistry and Physiology of Plants and Microorganisms (RAS-IBPPM), Italian National Institute for Environmental Protection and Research (ISPRA), Aarhus University of Denmark (AU) and other foreign universities and scientific research institutions. The center is currently undertaking Sino-foreign cooperative projects including DIKU project of Biogeochemistry in the Anthropocene, International Joint Research Center construction project of Tianjin “Belt and Road Initiative”, etc. The cooperative research results were published in international renowned journals such as Science and Environmental Pollution.
