Urban Mushrooms, Toxic Metals

Researchers in St. Petersburg, Russia, found high levels of arsenic, lead, and other heavy metals in wild mushrooms and berries gathered from forests near the city. Even in protected zones, many samples exceeded safety limits, raising concerns for urban foragers. A good reminder that mushrooms are bioaccumulators.
