Heavy metals in reindeer and their forage plants
An attempt was made to assess the level of heavy metal transfer from forage plants to reindeer (Rangifer tarandus L.) in an area in northern Lapland affected from dust from an open pit copper mine. Botanical analyses of rumen contents from reindeer provided information about the main plant species i...

An attempt was made to assess the level of heavy metal transfer from forage plants to reindeer (Rangifer tarandus L.) in an area in northern Lapland affected from dust from an open pit copper mine.
