| Short description: |
The xeno-estrogens BPA, OP and NP caused
distinct increases in the embryo production and
the total embryo number in P. antipodarum mostly
already at the lowest applied concentrations.
Evaluating the results for the tested substances,
we can conclude that the chronic effects on P.
antipodarum and their intensity are comparable
and in good accordance with the experiments of
Oehlmann et al. (2000) and Schulte-Oehlmann et
al. (2000). In the presence of BPA and OP where
we found sharper increases of the embryo numbers
and lower effect concentrations (LOEC, EC10 and
EC50), the reproductive performance was stimulated
to a greater extent than at exposure to NP.
There was no acute toxicity in the conducted
experiments.
Our results show that P. antipodarum is highly
sensitive to the xeno-estrogens BPA, OP and NP in
the sediment at environmentally relevant concentrations.
Finally, it can be concluded that the
sediment bioassay with P. antipodarum represents
a promising system for the identification of endocrine
disrupting substances and offers the more
general possibility as tool for the assessment of
sediment quality.
