Analytical methods have been developed that allow for the determination of 16 synthetic fragrance materials (SFMs) and 9 organic UV filters in wastewater treatment plant influent, influent solid, effluent, activated sludge, surface water, and sediment in rivers. The procedures mainly consist of solid phase extraction using two types of solid phase extraction cartridges followed by GC/MS in the SIM mode. Ultrasonic solvent extraction using dichloromethane/acetone was also performed for solid samples. SFMs and organic UV filters concentrations were determined for wastewater treatment plant influent and effluent samples collected at 47 plants and were also analyzed for 43 surface water samples and sediment samples in the Tone, Ara, Tama, and Turumi river. Twenty-three materials other than 3-(4-methyl-benzylidene) bornan-2-one (4-MBC) and 1-(1,1-dimethylethyl)-3,5-dimethy1-2,4,6- trinitrobenzene (musk xylene, MX) were detected in wastewater treatment plant influent and effluent. Twelve materials including organic UV filters were detected in all the influent samples. Three fragrance materials and two organic UV filters were detected in all the river samples. One fragrance material and two organic UV filters were also detected in all sediment samples.This is the first detailed report on fragrance materials and organic UV filters, in particular homosalate and octyl dimethyl p-amino benzoic acid, in wastewater treatment plant influent and effluent, surface water and sediment in rivers.
