  • Reducing Trichloramine in pool water
    Chlorination of water in swimming pools leads to the formation of trichloramine, a potentially harmful compound. How much of this by-product is formed depends on the amount of chlorine in the water...
  • Linking cell-population to whole-fish growth
    Before new chemicals can be approved, environmental risk assessments have to be carried out. But conventional toxicity testing with live fish is costly and time-consuming, and new substances contin...


  • Toxic effect of silver particles on algae examined
    It has long been known that, in the form of free ions, silver particles can be highly toxic to aquatic organisms. Yet to this day, there is a lack of detailed knowledge about the doses required to ...
