STEROIDAL METABOLITES IN CHILEAN RIVER SEDIMENTS INFLUENCED BY PULP MILL EFFLUENTS

The Biobío River basin (central south of Chile) is highly impacted by a variety of anthropogenic activities such as pulp mills subjected to different treatment processes. The cellulose production has notoriously increased in the Biobío Region in the last years reaching more that 80% of country produ...
