Metals enter the water-based trophic chains affecting the physiology and biodiversity of the water fauna. Lake ecosystems are more vulnerable to metal pollution compared to other inland water ecosystems due to their physicochemical characteristics. The evaluation of Cu, Zn and Pb impact on Lake Pamvotis of Ioannina district (NW. Greece) ecosystem is the aim of the present study. Water, surface and near-bottom samples as well as sediments were collected once per month over a year, from 2 different lake sites, one near the city and the other near the island of the lake. Fish tissues (muscle and liver) from various fish species (Cyprinus carpio, Carassius auratus, Parasilurus aristotelis, Tinca tinca and Rutilus rubilio) were also sampled. Our results show that metals (Zn, Pb and Cu) are significantly accumulated in the lake sediments indicating ecosystems' chronic insult by metals.
