“…19 Carpinteiro and co-workers investigated wastewater and indoor dust samples in human living environments such as private houses and car cabins in Spain and also reported that UV-326, UV-P, UV-328, and UV-327 were all major BZT contaminants. 18,37 Furthermore, it was found that UV-328 and UV-326 were dominant in river sediment in northern China and U.S. waters. 20 UV-328 and UV-234 were found to be the dominant analogues in the sediments of Japanese rivers and lakes, while contributions from other BZTs were almost negligible.…”

“…16,17 In this study, we focused the attention on benzotriazole UV stabilizers (herein abbreviated as BZTs, shown in Figure 1), also normally referred to as Tinuvins, which constitute one of the most important families of UV adsorbents. 18 These (2-hydroxyphenyl)benzotriazole derivatives are produced in large volumes and usually incorporated in various building materials, automobile polymeric components, waxes, films, and varnishes to prevent yellowing and degradation reactions by ultraviolet radiation from sunlight in the 320−400 nm (UV-A) and 280− 320 nm (UV-B) bands. 19,20 A few investigations indicated that certain benzotriazole derivatives, such as 2-(2-hydroxy-5-methylphenyl)benzotriazole (UV-P, Figure 1), 2-(3-tert-butyl-2-hydroxy-5-methylphenyl)-5-chlorobenzotriazole (UV-326), 5-chloro-2-(3,5-di-tert-butyl-2-hydroxyphenyl)benzotriazole (UV-327), and 2-(3,5-di-tert-amyl-2-hydroxyphenyl)-benzotriazole (UV-328), are present in indoor dust, 18 sewage sludge, 20 and marine sediment at urban estuaries.…”

“…The sample pretreatment procedure is similar to previously reported methods with slight modifications. 18,19 In brief, approximately 1 g of sample was mixed with 15 g of anhydrous sodium sulfate and extracted with hexane/dichloromethane (7:3, v/v) at 90°C and 1500 psi in three static extraction cycles of 10 min using an accelerated solvent extractor (ASE 350, Dionex Inc., Sunnyvale, CA). The extract was concentrated by rotary evaporation to ∼2 mL and fractioned on a Biobeads S-X3 (Bio-Rad Laboratories, Hercules, CA) gel permeation chromatography column (GPC, 400 × 30 mm, i.d.).…”

ABSTRACT:The environmental contamination and fate of benzotriazole UV stabilizers (BZTs) have received increasing attention due to their large production volume and wide usage in various consumer and industrial products. In the present work, 60 municipal sewage sludge samples from wastewater treatment plants (WWTPs) in 33 cities in China were collected to investigate the occurrence and distribution of 9 frequently used BZTs. The most dominant analogue was 2-[3,5-bis(1-methyl-1-phenylethyl)-2-hydroxyphenyl]-benzotriazole (UV-234) at a median concentration of 116 ng/ g (dry weight) and accounted on average for 27.2% of total BZTs. The abundance was successively followed by 2-(2-hydroxy-5-tert-octylphenyl)benzotriazole (UV-329, average 24.3%), 2-(2-hydroxy-3-tert-butyl-5-methylphenyl)-5-chlorobenzotriazole (UV-326, average 22.2%), 2-(3,5-di-tert-amyl-2-hydroxyphenyl)benzotriazole (UV-328, average 17.7%), and 2-(2-hydroxy-5-methylphenyl)benzotriazole (UV-P, average 6.6%), with median concentrations of 66.8, 67.8, 57.3, and 20.6 ng/g, respectively. 5-Chloro-2-(3,5-di-tert-butyl-2-hydroxyphenyl)benzotriazole (UV-327) and 2-(3-sec-butyl-5-tert-butyl-2-hydroxyphenyl)benzotriazole (UV-350) had low detection frequency, while 2-(3,5-di-tert-butyl-2-hydroxyphenyl)benzotriazole (UV-320) and 2-(5-tert-butyl-2-hydroxyphenyl)benzotriazole (UV-PS) were not detectable in any sample. To our knowledge, this is the first study reporting the occurrence of UV-234, UV-329, and UV-350 in sewage sludge in China. Significant correlations were found among the BZT concentrations and also with a WWTP characteristic (daily treatment volume). Furthermore, results from degradation prediction and multimedia fate simulation based on a quantitative structure−property relationship (QSPR) model at screening level also implied that the commercial BZT chemicals and their plausible transformation products might be persistent in the environment.

“…Substancje te łatwo adsorbują się na cząstkach stałych, w USA w osadach dennych rzeki Pawtuxet związki z grupy BTR wykryto w granicach 4300-5200 mg/kg [15], w Chinach w rzece Songhau od 0,31 do 7,12 μg/kg [14]. Natomiast w Hiszpanii w kurzu domowym zawartość tych związków wahała się w przedziale 22 -657 μg/kg [3]. W glebie zazwyczaj BTR bada się w okolicach dróg, stref przemysłowych, na terenach miejskichw Sztokholmie wartość ta wyniosła 3,7 μg/g dla UV 360 nm [2,9].…”

a Benzotriazole ultraviolet stabilizers (BUVSs) have been commonly used in industrial and household product formulations, and have been detected in biosolids from wastewater treatment plants. However, little is known about their occurrence and dissipation behavior in the soil environment associated with biosolid application. This study investigated the occurrence and dissipation of five typical BUVSs (UV-326, UV-327, UV-328, UV-329 and UV-P) in biosolid-amended soils, and the uptake of these biocides by plants.The field trial includes two treatment groups: old groups with biosolid application at rates of 5, 10, 20 and 40 t ha À1 every year within 5 years, and new groups with only one biosolid application. The resultsshowed that the five BUVSs could be detected in most biosolid-amended soils at a few to tens of ng g Environmental impactBenzotriazole ultraviolet stabilizers (BUVSs) are widely used as additives in paints, coatings, adhesives, polymeric surfaces, food packing lms and construction materials. They have been detected in biosolids from wastewater treatment plants. With application of biosolid to agricultural land, these chemicals may contaminate the agricultural soils and thus affecting the terrestrial ecosystem and human health. BUVSs (UV-326, UV-327, UV-328, UV-329 and UV-P) could be detected in the biosolid-amended soils at a few to tens of ng g À1 levels. This one year monitoring study demonstrated slow dissipation of the BUVSs in soil environments.
