Resumen:
Bioindicators can be used to determine spatial
and/or temporal variations of heavy metals in a certain
coastal or marine environments. This study investigated the
potential use of the burrowing crab Neohelice granulata
from two different locations in the Bahı´a Blanca estuary, a
moderately polluted ecosystem. Concentrations of zinc (Zn),
nickel (Ni), and lead (Pb) in soft tissues of male and female
crabs were measured. In addition, concentrations of the three
metals in eggs were compared with concentrations in female
crabs. No geographical differences were found for any of the
three metals, whereas sexual and seasonal differences were
obtained for Zn and Ni, with the winter season posing lower
concentrations. Moreover, the three metals were detectable
in eggs and were lower than concentrations in female crabs
(except for Zn). Finally, the usefulness of this species as a
potential bioindicator of heavy-metal pollution within this
estuarine ecosystem is discussed.
