             abstract = "Many studies have determined the concentration of trace elements 
                         in river sediments in Brazil. Notwithstanding, mercury assessments 
                         are scarce, especially because of exclusive extraction techniques 
                         and expensive analysis techniques. Still, this element is known 
                         for its toxicity, persistence, and bioaccumulation, making its 
                         presence in the environment an important factor for biota and 
                         human health. For this reason, the objective of this study was to 
                         determine the mercury concentration in the sediment of the Pelotas 
                         River basin, located on the border of the states of Santa Catarina 
                         and Rio Grande do Sul. The sediment was collected at eight 
                         locations of the Pelotas basin and, after drying, the mercury was 
                         quantified by atomic absorption spectrometry based on the 
                         Zeeman-background correction, coupled to a pyrolysis reactor. The 
                         mercury concentrations in the sediments of the Pelotas River 
                         varied from 40.5 ng g -1 to 62.0 ng g -1 and presented a positive 
                         correlation with the fraction of silt and clay. The concentrations 
                         of mercury found in sediments of the Pelotas River basin have a 
                         low probability of negatively affecting the biota. Nonetheless, 
                         given the persistence and bioaccumulation potential of this 
                         element, the aforementioned region needs further studies to 
                         quantify the risks it may cause on the local biota and human
