orthoacetate (TMOA) was tested for acute toxicity towards daphnia
according to OECD-Test Guideline 202 (1984) in compliance with GLP. In
order to investigate the influence of the test item towards the daphnia,
the swimming behaviour of the animals was recorded. Under the conditions
used for the test, there was a significant immobilisation of the daphnia
at concentrations > 700 mg/L. As a conclusion
of the analytical part of this study, it can be stated, that the
concentrations of Trimethyl orthoacetate (TMOA) remained
sufficiently stable during incubation, by the performance of a
a result of the supporting analysis it can be stated that the results of
the biological part should be based on the nominal concentrations
applied because the recoveries of the nominal concentrations were all
