The sonochemical degradation of 5 lg l1 triclosan, a priority micro-pollutant, in various environmental samples (seawater, urbanrunoff and influent domestic wastewater) as well as in model solutions (pure and saline water) was investigated. Experiments were conductedwith a horn-type sonicator operating at 80 kHz frequency and a nominal applied power of 135 W, while solid-phase microextractioncoupled with gas chromatography–electron capture detector (SPME/GC–ECD) was employed to monitor triclosan degradation.The latter followed pseudo-first order kinetics with the rate constant being (min1): 0.2284 for seawater > 0.1051 for 3.5% NaCl in deionisedwater > 0.0597 for centrifuged urban runoff 0.0523 for untreated urban runoff > 0.0272 for deionised water > 0.0063 for wastewaterinfluent. SPME/GC–ECD and SPME coupled with gas chromatography–mass spectrometry (SPME/GC–MS) were also used tocheck for the formation of chlorinated and other toxic by-products; at the conditions in question, the presence of such compoundswas not confirmed.
