Baptista, C; Seixas, F; Gonzalo-Orden, JM; Patinha, C; Pato, P; da Silva, EF; Casero, M; Brazio, E; Brandão, R; Costa, D; Mateus, TL; Oliveira, PASimple Summary Heavy metal(loid)s are hazardous substances for humans, animals and ecosystems. The liver is one of the most affected organs, presenting lesions after being acutely or chronically exposed to these substances. In this study, hepatic metal(loid)s' concentrations were associated with biliary hyperplasia, which was the most common hepatic lesion found in a group of western-European hedgehogs from res...

Costa, MR; Marszałek, H; da Silva, EF; Mickiewicz, A; Wąsik, M; Candeias, CProduction of acid mine drainage may occur during mining operations and may continue for many years after closure. In some cases, especially when host rock is capable of reacting with acidic drainage, metal concentrations may decrease over time and distance. Seasonal variations in water flow rate also play an important role in metals concentration both in surface and groundwater. The present study evaluates the...
