Test material

Specific details on test material used for the study:
following UV light stabilizer (UVLS) were investigated:
- 2-(2-Hydroxy-5-methylphenyl)-benzotriazole (UV-P)
- 2-(5-Chloro-2-benzotriazolyl)-6-tert-butyl-p-cresol (UV-326)
- 2,4-Di-t-butyl-6-(5-chloro-2H-benzotriazol-2-yl)phenol (UV-327)
- 2-(20-Hydroxy-30,50-di-tert-amylphenyl) benzotriazole (UV-328)
- 2-(2H-benzotriazol-2-yl)-4-(1,1,3,3-tetramethylbutyl)phenol (UV-329)
- 2,4-Di-t-butylphenyl-3,5-Di-t-butyl-4-hydroxybenzoate (UV-120)
- 2-(2H-Benzotriazol-2-yl)-4,6-bis(1-methyl-1-phenylethyl) phenol (UV-234)
- 2-(4,6-Diphenyl-1,3,5-triazine-2-yl)-5-[(hexyl)oxy]-phenol (UV-1577)

Study design

Details on sampling:
Surface water and sediment samples were taken from rivers (22 sites), lakes (3 sites) and sewage treatment plat effluents (STPE) (4 sites) in Saitama Prefecture, Japan, in August and September 2008. Samples were collected from 29 sampling sites: 2 streams with direct inputs of domestic wastewater, 4 STPE, 6 rivers that have been heavily polluted by industrial and domestic wastewaters, 12 moderately contaminated rivers, 2 little contaminated rivers and 3 lakes as background sites. All samples were grab samples.

Any other information on results incl. tables

Surface water:

The recovery ratios of all eighteen analyte samples ranged from 80 to 113%, except for UV-1577, which had a slightly higher recovery ratio. The limits of detection (LODs) ranged from 0.1 to 3.0 ng/L.

Sediment:

The recovery ratios of all compounds ranged from 70 to 125%. The LODs in the sediment samples were relatively low, ranging from 0.05 to 1.0 ng/g dry weight, except for UV-328. Procedural blanks showed UV-328 in each analysis. Therefore, the LOD of UV-328 was determined to be 10 ng/g dry weight.

Applicant's summary and conclusion

Conclusions:
The study showed the occurrence and concentrations of UV light stabilizers (UVLS) in surface water and sediment from rivers, lakes, STPE and industrial wastewaters. UV-328 was the most dominant UVLS found in river and lake water and STPE. To a much lower extent UV-326 was also found. The compositions of UVLS in sediment were similar for the tested sampling sites. UV-328 and UV-234 accounted for 70 to 80% of the total contaminants identified in all sediment. UV-326 had a strong linear correlation between UV-327 as well as UV-328 in all sediment.
Executive summary:

The occurrence of UV light stabilizers (UVLS) were measured in water and sediment collected from 22 rivers, four sewage treatment plant effluents (STPE) and three lakes in Japan. Total UVLS levels ranged from N.D. to 4180 ng/L and to 1735 µg/kg dry wt in surface water and in sediment, respectively. UVLS were observed in all sediment and their compositions showed similar patterns, with UV-328 and UV-234 as the most prevalent compounds. Concentrations of UV-327 and UV-328 had strong correlation between those of UV-326 in sediment.
