76 Application of Ionizing Radiations | Progress Report

In collaboration with some other groups which
study alternative treatments for wastewater,
LEBA participates of their work applying and
developing suitable biological assays for mea-
suring the efficacy of developing treatment
processes such as polymeric membranes and
other POAS (oxidative processes). They are
textile industries, EPUSP, Instituto Butantan
and SENAI.

Acute toxicity of pharmaceuticals was deter-
mined for fluoxetine, diclofenac, propranolol
and their mixture, using two biological levels
of aquatic organisms (V. fischeri and D. similis).
All of them were also treated by radiation with
Electron Beam Accelerator. Partial results are
presented in Figure 53.

Figure 53. Acute toxicity (in Toxic Units, TU=100/EC50) of
diclofenac (DCF) and fluoxetine (FLX) individually and in
mixture performed with V. fischeri. Data in triplicate. Initial
condition: DCF concentration = 50 mg L-1; FLX concentration =
5 mg L-1; pH0 = 6.79 ± 0.77.
