“…For example, this may occur near sewage treatment plants where indirect photoreactions can be accelerated due to the high concentration of CDOM in the effluent. 407,408 Since our last update, 9 additional research has confirmed that indirect photodegradation is an important mechanism for the breakdown of a wide-range of contaminants, including healthrelated compounds, [409][410][411] carbon nanomaterials, [412][413][414][415] pesticides, [416][417][418] and UV filters. 408 Improved evaluation of these photodegradation processes is now being achieved with readily accessible models of solar UV radiation 320 to improve predictions of degradation of contaminants in the environment.…”

The Environmental Effects Assessment Panel (EEAP) is one of three Panels of experts that inform the Parties to the Montreal Protocol. The EEAP focuses on the effects of UV radiation on human health, terrestrial and aquatic ecosystems, air quality, and materials, as well as on the interactive effects of UV radiation and global climate change. When considering the effects of climate change, it has become clear that processes resulting in changes in stratospheric ozone are more complex than previously held. Because of the Montreal Protocol, there are now indications of the beginnings of a recovery of stratospheric ozone, although the time required to reach levels like those before the 1960s is still uncertain, particularly as the effects of stratospheric ozone on climate change and vice versa, are not yet fully understood. Some regions will likely receive enhanced levels of UV radiation, while other areas will likely experience a reduction in UV radiation as ozone- and climate-driven changes affect the amounts of UV radiation reaching the Earth's surface. Like the other Panels, the EEAP produces detailed Quadrennial Reports every four years; the most recent was published as a series of seven papers in 2015 (Photochem. Photobiol. Sci., 2015, 14, 1-184). In the years in between, the EEAP produces less detailed and shorter Update Reports of recent and relevant scientific findings. The most recent of these was for 2016 (Photochem. Photobiol. Sci., 2017, 16, 107-145). The present 2017 Update Report assesses some of the highlights and new insights about the interactive nature of the direct and indirect effects of UV radiation, atmospheric processes, and climate change. A full 2018 Quadrennial Assessment, will be made available in 2018/2019.

“…This agrees with literature findings for compounds that are prone to indirect photodegradation. [16][17][18][19] Interestingly, when DOC was increased, the increase in the removal of BP was similar regardless of the presence of HCO 3 -, Cland SO 4…”

“…In addition, in fresh water, the hydroxyl radical mechanism is also involved. Semones et al 19 showed that the degradation by simulated solar irradiation of benzophenone-3 and sulisobenzone was enhanced in the presence of fulvic acid, a natural organic matter, and in filtered wastewater effluent and river water. The main pathway for degradation is the reaction with • OH.…”

This study presents the results from a bench-scale UV irradiation experiment of benzophenone (BP) in different water matrices. Despite the reported resistance of BP to UV-irradiation, it was successfully degraded in solution when intensively irradiated by UV light in a batch reactor for 4 h. In this way, it was possible to remove 56 and 45 % of 1.0 and 10 µg•L-1 of BP in Milli-Q water, respectively. The addition of a mixture of anions suppressed the degradation of BP at the lower concentration level by 20 %. The addition of a dissolved organic carbon (DOC) surrogate mixture (DOC:BP mole ratio of 3000:1) increased the degradation of BP in Milli-Q water (removal 80 %). At 1.0 µg•L-1 of BP and 1.0 mg•L-1 of DOC, removal was 70 %, while at 10 µg•L-1 of BP and 10 mg•L-1 of DOC, there was no observable difference in removal compared with the removal in Milli-Q water. The results show that both DOC and anions influence the photodegradation of BP. Furthermore, it was shown that the removal efficiency depends on the concentration of BP. These findings show the importance of a detailed characterisation of the water matrix in studies relating to the removal of micropollutants during UV irradiation.

Rationale Exposure to UV light can induce adverse effects on human health, such as photo‐aging, immunosuppression, and cancer. Sunscreens are used to prevent the absorption of UV rays, but certain UV‐filtering compounds have been shown to disrupt endocrine systems or act as carcinogens. To assess the effects of the exposure to such compounds, it is important to study the pathways by which they are biotransformed in the body. Methods Liquid chromatography coupled to high‐resolution tandem mass spectrometry (LC/HRMS/MS) was employed to evaluate the oxidative metabolism and, specifically, the formation of reactive metabolites of six active ingredients commonly used in sunscreen formulations: oxybenzone, avobenzone, homosalate, octisalate, octocrylene, and octinoxate. In vitro incubations were performed with human and rat liver microsomes in the presence of β‐nicotinamide adenine dinucleotide phosphate and glutathione. An LC/HRMS/MS method was developed to identify metabolites employing a biphenyl reversed‐phase column for separating parent molecules, metabolites, and glutathione (GSH) adducts. Results Each tested compound resulted in the formation of several metabolites, including at least one GSH adduct. Compounds containing ester groups were hydrolyzed, and some metabolites of the free acid forms were also detected. High‐resolution MS/MS data was crucial for the structural elucidation of metabolites and GSH adducts. Fragmentation pathways were proposed for all parent compounds, as well as each described metabolite and adduct. Conclusions The results of this study will help better understand the metabolism and detoxification pathways of these xenobiotics.
