The quanitative significance of the surface microlayer (SML) to the environmental fate of the industrial plasticizer di(2-ethylhexyl)phthalate (DEHP), in marine coastal systems was established by the use of experimental microcosms. The effects of season, sea-state and associated solvents were investigated. The results demonstrated that the SML community rapidly degraded DEHP to such an extent that under certain treatment conditions biodegradation was the dominant removal process compared with physical transport. Biodegradation of DEHP by the SML biota was estimated to account for at least 30% of the total budget. Extrapolation of the laboratory results to the simulated field system (the West Passage of Narragansett Bay, RI), is discussed within the context of potential artifacts of the marine microcosms.
