nology may guarantee that radiation may re-
duce toxicity of treated effluents, offering a
safe technology or its combined processes for
complex effluent.

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 lev-
els of aquatic organisms (V. fischeri and D. si-
milis). All of them were also treated by radi-
ation 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.
