Resumo
Surfactants, as detergent active substances, are an important source of pollution causing biological adverse effects to
aquatic organisms. Several data have been showing ecological disturbance due to the high concentration of surfactants
on receiving waters and on wastewater treatment plants. Ionizing radiation has been proved as an effective technology
to decompose organic substances and few papers have included ecotoxicological aspects. This paper shows the
reduction of acute toxicity of a specific surfactant, sodium dodecyl sulfate (SDS), when diluted in distilled water and
submitted to electron beam radiation. The study included two test-organisms, the marine bacteria Vibrio fischeri and the
crustacean Daphnia similis. Radiation processing resulted in an important acute toxicity removal for both assays, which
can be summarized between 70% and 96%, using 3.0, 6.0, 9.0 and 12.0 kGy as radiation doses. Nevertheless, lower
doses demonstrated better effect than 9.0 and 12.0 kGy and the bacterium assay was more sensitive to SDS than
crustacean assay.
