Heavy metals in the Finnish environment have declined dramatically over the last 15 years, according to the Finnish forest research institute (Metla). Levels of lead and cadmium in mosses are down by 78% and 67% respectively, the institute reports. Main causes include the phase-out of leaded petrol and lower cadmium emissions from waste incineration and mineral fertilisers. Chromium and copper concentrations have fallen due to environmental improvements at metallurgical plants. Falling emissions of copper and nickel from Russian smelters have also contributed to the improvements. See Metla.
