  • Testing ecological toxicity in rivers

    Water quality in rivers is commonly classified according to its physical and chemical properties, but this may not fully describe its biological health. Polish researchers have tested a new method of water assessment, which looks at the toxicity to organisms of not just water, but also sediment and floodplain soil samples. This provides a more complete picture of a river's health and may help ...

  • Toxic by-products of ballast water treatment evaluated

    A new study has evaluated disinfection by-products (DBPs) formed during the treatment of ballast water. As some of the DBPs produced are hazardous, the study concludes that more information is needed to ensure DBPs from treatment methods do not harm human health or aquatic environments. Ships hold ballast water in tanks to provide stability at sea. Frequently, water is taken at one port ...

  • Strong Sorption of Toxic Chemicals to Nanoplastics

    Nanoplastics adsorb toxic chemicals up to 100 times stronger than microplastics. This follows from recent research at IMARES and the Aquatic Ecology and Water Quality Management group. PhD student Ilona Velzeboer measured the adsorption of toxic chemicals to microplastics, nanoplastics, and other nanoparticles such as carbon nanotubes and fullerenes. This way, a good comparison with the ...
