Biomonitoring toxic and essential element accumulation in trout in the as pontes mine pit lake (NW Spain).

This study investigated the accumulation of toxic and essential elements in trout from a pit lake situated in the surroundings of the abandoned As Pontes de García Rodríguez lignite mine (NW Spain). The element concentrations were compared with those measured in fish from upstream of the River Eume and from a local fish farm. Liver and muscle samples from fish captured in the lake (n = 16), river (n = 14) and fish farm (n = 10) captured in March-April 2022 were acid digested and analyzed by ICP-MS.
