Large spill of mining wastes in Portelo stream: impacts on ecosystem integrity ...

Streams located at Montesinho Natural Park (NE Portugal) have high potential for brown trout (Salmo trutta) angling. However, in this territory there are several abandoned mine sites. Therefore, the continuous drainage of fine grained tailings can be particularly problematic due to arsenic, copper, aluminium and zinc. However, until now no significant disturbance was detected in water quality and in biota. Neve...
