In the last decade, pharmaceuticals have beenreported in the water cycle were some types of them may not be completelyremoved employing sewage treatments, leading to the subsequent pollution ofaquatic ecosystems. Derived from data found in literature [1,2], the analgesicacetaminophen (AP) was selected for this study.  AP oxidation from aqueous solution by the UV/H2O2process is evaluated and studied.  Aquatictoxicity of this treatment was evaluated in an acute toxicity study using Daphnia magna. Different levels of H2O2and radiation were used at the same pollutant concentration. Results have shownthat there is an optimum condition for the process employing 250 mg L -1of the oxidant.. It can be concluded that the UV/H2O2 isa feasible technology to produce AP mineralization in very short periods oftime employing low amounts of H2O2 and low power germicidalUV lamp.
