Abstract : Plankton oil monolayers spread on synthetic sea water and exposed to radiation approximating sunlight expand rapidly during the first several hours of exposure. There is an accompanying increase in collapse pressure. One case studied showed film breakdown to begin after 15-hours exposure time as evidenced by a decrease in the specific area of the film after this time and by the solution of the reaction products. It is concluded that plankton oil films do not disappear by photocatalyzed oxidation for periods equivalent to at least two days sunlight but they w ll subsequently dissolve by molecular scission.
