This study examined how different types of fungi can absorb toxic metals from polluted sediments in the Baltic Sea caused by old paper mills. Researchers tested 26 native Swedish fungi species and found that Phlebia tremellosa was especially effective at absorbing various toxic metals like zinc, cadmium, and copper. These findings suggest that fungi could be used as a natural way to clean up contaminated waterways, offering a sustainable solution to an environmental problem affecting Nordic countries.
