    • The influence of B2O3 on the viscosity of high Ti-bearing BF slag is studied under Ar atmosphere from 1 773 K (1 500 degrees C) to about 1 593 K (1 320 degrees C). The results show that the addition of B2O3 can decrease the viscosity of high Ti-bearing BF Slag containing UPC, consequently improve its fluidity. With the existence of 1.5% UPC, when the content of B2O3 increased from 0 to 4.1%, the volume fraction of perovskite decreased from 7.7% to 1.6% at 1 610 K. Meanwhile, the liquidus temperatures decreased from 1 619 K to 1 613 K. At a lower temperature, B2O3 was easy to form a eutectic and decreased the viscosity of molten slag. At a higher temperature, some tetrahedron [BO4](5-) changed into triangle [BO3](3-) which would disintegrate the chains/molecules of molten matrix and decreased its viscosity.

  • Emerging contaminants: A One Health perspective
  • 2024
  • Ingår i: Innovation. - 2666-6758. ; 5
  • Forskningsöversikt (refereegranskat)abstract
    • Environmental pollution is escalating due to rapid global development that often prioritizes human needs over planetary health. Despite global efforts to mitigate legacy pollutants, the continuous introduction of new substances remains a major threat to both people and the planet. In response, global initiatives are focusing on risk assessment and regulation of emerging contaminants, as demonstrated by the ongoing efforts to establish the UN's Intergovernmental Science-Policy Panel on Chemicals, Waste, and Pollution Prevention. This review identifies the sources and impacts of emerging contaminants on planetary health, emphasizing the importance of adopting a One Health approach. Strategies for monitoring and addressing these pollutants are discussed, underscoring the need for robust and socially equitable environmental policies at both regional and international levels. Urgent actions are needed to transition toward sustainable pollution management practices to safeguard our planet for future generations.
