Calidad ecotoxicológica de los sedimentos en fiordos del sur de Chile
We analysed the ecotoxicological quality of sediments in Moraleda, Puyuguapi and Elefantes Channels and Aysén Fjord, located between 44º and 46.5ºS, using non-specific tests in order to evaluate their base conditions in terms of possible pollutants that may have been introduced in the area. The surv...
