(MT) response and bioaccumulation under control and acute mercury exposure
were investigated in scats (Scatophagus argus). Scats were exposed
to different mercury concentrations (10, 20 and 30 μg Hg L-1)
for 24, 48 and 72 h. Total MT levels were determined by Enzyme-Linked
Immunosorbent Assay (ELISA) method. Mercury contents were determined through
cold Vapour atomic Absorption spectrometry. Induction of MT during exposure
was tissue specific, displaying different response pattern in gill and
liver. Mercury accumulated much stronger in liver than gill and the latter
also showed lower MT level. MT biosynthesis in liver showed a significant
increase after exposure to different mercury concentration during different
times. This increase was significantly correlated with mercury bioaccumulation.
In contrast, presence of different mercury concentration during different
times did not significantly modify total MT except for 72 h exposure at
30 μg L-1 in gills. The results suggest that this form
of MT existing in S. argus was Hg-inducible and could be extended
the as a biomarker of mercury pollution in ecosystems.]]>Bervoets, L., M. Lodts, K. Van Campenhout and R. Blust,20022002pp: 250-261pp: 250-261Bonwick, G.A., P.R. Fielden and D.H.
