  • Reduced heavy metals and nitrogen in mosses reflect falling air pollution across Europe

    Deposition of heavy metals and nitrogen is falling across Europe, a new study suggests. The researchers used the levels of these pollutants in mosses as indicators of how deposition has changed from 1990 to 2010. These reductions are likely to be the result of effective air pollution policies, they say. Heavy metals, such as lead and cadmium, can be toxic to both humans and wildlife, and ...
