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
health.",
