概要	The fates of 4 aquatic contaminants, 2,4-dichlorophenoxyacetic acid (2,4-D) herbicide, the bisphenol A (BPA) endocrine disruptor, Na butylnaphthalenesulfonate (BNS) and benzyldodecyldimethylammonium bromide (BDDAB) surfactants by the TiO2-photoassisted ozonization (TiO2/O3/UV) were studied indoors under lab. conditions (super-high-pressure Hg lamp) and outdoors under natural sunlight. In lab. expts. the TiO2/O3/UV methodol. led to significant increases in degrdn. efficiency relative to ozonization (dark: O3; or under UV light: O3/UV) and to the TiO2-photoassisted method of oxygenated dispersions (TiO2/O/UV). Mineralizations of the substrates were monitored by total org. C (TOC) assays.
