-Emission of priority heavy metals (cadmium, lead and mercury) **decreased significantly since 1990**. Most values show reductions by about 50 to 93% compared to the base year, with the majority of the achievements originating from the early 1990's though.+Emission of priority heavy metals (cadmium, lead and mercury) **decreased significantly since 1990**.

-2019 and 2020 emissions saw a substantial reduction trend for most heavy metals.+In 2024 the emissions from arsenic, cadmium, mercury and selenium declined between 2% (selenium) und 7% (cadmium). The emissions of copper, chrome, nickel, lead and zinc increased between 0,6% (copper) and 2,1% (zinc).
