“…Patterns of mercury contamination have been intensely studied around dams (Budnik and Casteleyn, 2019; Millera Ferriz et al, 2021; Pestana et al, 2019; Wang et al, 2004). Few ecotoxicological studies focused on freshwater turtles exist [(Thompson et al, 2018) but see (Lu et al, 2019; Tada et al, 2007)], with most focusing on fish due to their economic importance and use as a food resource (Duponchelle et al, 2021; Moran et al, 2018). Despite this, the presence of mercury has been documented in turtles from temperate (Burger and Gibbons, 1998; Meyer et al, 2014; Slimani et al, 2018) and tropical regions (Eggins et al, 2015; Schneider et al, 2009; Schneider et al, 2010).…”

Dams create many impacts on freshwater ecosystems and biodiversity. Freshwater turtles are at direct and indirect risk due to changes caused by damming including the loss of terrestrial and aquatic nesting and feeding habitats, changes to resource availability and reduced dispersal. We reviewed the global scientific literature that evaluated the impact of dams on freshwater turtles, and carried out additional searches of literature published in seventeen languages for studies evaluating actions to mitigate the impact of dams. The search produced 43 published articles documenting dam impacts on 29 freshwater turtle species from seven families (Chelidae, Chelydridae, Emydidae, Geoemydidae, Kinosternidae, Podocnemididae and Trionychidae) in 13 countries. More than a third of studies (41.9%, n = 18) focused on nine North American species of the Emydidae. Few studies were found from Europe and Asia and none from Africa. The number of studies, life-history stage studied and threat status differed significantly between temperate and tropical latitudes. Most studies were from temperate latitudes, where studies focused more on adults and less threatened species compared with tropical latitudes. Studies evaluated dam impacts as barriers and changes to water flow and quality, but no studies were found that assessed turtles and changes to land cover or mercury caused by dams. More than half of the studies (59%, n = 24) suggested actions to help mitigate dam impacts. Yet, only four studies on three temperate and one tropical species documented the effect of interventions (dam removal, flow management, artificial pond maintenance and community-based action). These findings demonstrate a lack of documented evidence evaluating dam impacts on freshwater turtles particularly in tropical regions. This lack of evidence reinforces the importance of strengthening and maintaining robust long-term studies of freshwater turtles needed to develop effective conservation actions for this group of vertebrates.

“…This is done to prevent yellowing and degradation that could result from prolonged exposure to UV radiation ( Andrady and Rajapakse, 2016 ). Such widespread use leads to detectable concentrations of BT-UVs in environmental matrices, which have been reported for surface water ( Lu et al., 2016 ), sea water ( Montesdeoca-Esponda et al., 2020 ), sediment ( Cantwell et al., 2015 ), biota ( Lu et al., 2019 ), wastewater ( Song et al., 2014 ) and plastic debris ( Rani et al., 2017 ). The toxic and bio-accumulative properties of BT-UVs are well documented ( Kim et al., 2011 ; Liang et al., 2019 ); and as a result, some BT-UVs have been classified under the European Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) regulation as substances of very high concern (European Chemicals Agency (ECHA), 2014 ).…”

Phase partitioning, transport and sources of Benzotriazole Ultraviolet Stabilizers during a runoff event

Highlights Despite high hydrophobicity some UV-BTs can be transported in the dissolved phase. Most plastic debris in the watershed is more likely a sink than a source of UV-BTs. Flushing of surfaces mobilizes particulate UV328 and UV234 to the urban stream. Use of UV328 in automotive applications possibly explains its presence in road dust.

“…Due to their resistance to the degradation processes, benzotriazole-based UV absorbers accumulate and persist in the environment. The presence of benzotriazoles in aquatic environment, such as marine organisms, river and lake waters, and sediments, is a major threat [ 17 , 18 , 19 , 20 , 21 , 22 , 23 ]. In addition, UV-P, UV-326, UV-327, and UV-328 were detected in house dust [ 24 , 25 ].…”

“…BUVs were also determined in PM10 outdoor air, from industrial areas in Tarragona, Spain [ 26 ]. Benzotriazoles trends to accumulate in the tissues of living organisms [ 22 , 27 , 28 , 29 , 30 , 31 ] and were detected in human breast milk [ 32 , 33 , 34 ]. Exposure to benzotriazoles via food packaging seems insignificant but is, potentially, harmful.…”

Degradation of Benzotriazole UV Stabilizers in PAA/d-Electron Metal Ions Systems—Removal Kinetics, Products and Mechanism Evaluation

2022

Benzotriazole UV stabilizers (BUVs) have gained popularity, due to their absorption properties in the near UV range (200–400 nm). They are used in the technology for manufacturing plastics, protective coatings, and cosmetics, to protect against the destructive influence of UV radiation. These compounds are highly resistant to biological and chemical degradation. As a result of insufficient treatment by sewage treatment plants, they accumulate in the environment and in the tissues of living organisms. BUVs have adverse effects on living organisms. This work presents the use of peracetic acid in combination with d-electron metal ions (Fe2+, Co2+), for the chemical oxidation of five UV filters from the benzotriazole group: 2-(2-hydroxy-5-methylphenyl)benzotriazole (UV-P), 2-tert-butyl-6-(5-chloro-2H-benzotriazol-2-yl)-4-methylphenol (UV-326), 2,4-di-tert-butyl-6-(5-chloro-2H-benzotriazol-2-yl)phenol (UV-327), 2-(2H-benzotriazol-2-yl)-4,6-di-tert-pentylphenol (UV-328), and 2-(2H-benzotriazol-2-yl)-4-(1,1,3,3-tetramethylbutyl)phenol (UV-329). The oxidation procedure has been optimized based on the design of experiments (DoE) methodology. The oxidation of benzotriazoles follows first order kinetics. The oxidation products of each benzotriazole were investigated, and the oxidation mechanisms of the tested compounds were proposed.
