Summary: Breast milk in South China contains previously unidentified triazine UV filters (TA-UVFs), benzotriazole (BTR)-UVFs, and benzophenone (BP)-UVFs. The use of personal care products significantly affects the levels of these UV filters in breast milk. Including TA-UVFs in assessments could increase the overall daily intake of UV filters for infants through breastfeeding by 28%.

Summary: This study measured the levels of synthetic phenolic and amino antioxidants and ultraviolet filters in popular children's car seats. The results showed that the levels of the target compounds were significantly higher in foam and composite samples compared to fabric samples. The most abundant compounds were isooctyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate and 2,4-di-ten-butylphenol. The levels of amino antioxidants and ultraviolet filters were lower than those of phenolic antioxidants.

Summary: Tourism is a significant economic sector globally, but its impact on coastal areas, particularly in relation to personal care products such as UV filters and stabilizers, can lead to pollution issues. This study focused on assessing the presence and exposure of organic UV filters and stabilizers in Gran Canaria Island to draw conclusions for similar regions. The research highlighted the importance of understanding the distribution of these pollutants in different matrices for environmental managers in coastal areas reliant on tourism.

Summary: The availability of UV filters in the United States is behind that of the EU due to different approval processes. Most US-approved filters show minimal skin sensitization, while most EU-approved filters show no sensitization. Many new UV filters are available in the EU but not yet in the United States.

Summary: Some chemical components in sun cream filters have potential risks to health and the environment. This study compares conventional commercial sunscreens with natural products in terms of their endocrine-disrupting effects. Different sun cream filters were evaluated and compared, considering safety assessments from Environmental Working Group and the EU Registration, Evaluation, Authorization and Restriction of Chemicals Regulation. While some organic sun cream filters pose risks, inorganic filters like titanium dioxide and zinc oxide have very low risk as they are not absorbed through intact or damaged tissues. However, the legislation does not require manufacturers to specify the concentration of each substance, providing limited information for consumers.

Summary: The aim of this study was to design a sample preparation procedure that is compatible with LC-MS and SPME, and to determine the biodegradation kinetics of diverse chemicals in closed batch tests with activated sludge. The results showed that ethanol could effectively stop biodegradation and extract sorbed chemicals from activated sludge under low cosolvent concentrations. This study demonstrated a 'cold' alternative to an OECD 314b test and provided an approach to determine biodegradation kinetics for mixtures of diverse chemicals.

Summary: This study investigated the effects of different concentrations of AVO on Mytilus galloprovincialis at sperm and adult levels. The results showed significant overproduction of superoxide anions and DNA damage in sperm exposed to AVO, as well as a decrease in sperm viability at higher concentrations. In exposed adults, there was a decrease in metabolic capacity at the lowest concentration and an increase in total protein content and antioxidant defense enzyme activity at the highest concentration.

Summary: In this study, the microbial communities in two coastal areas near the estuaries of the LH River and YLJ River in the Northwestern Pacific Ocean were investigated. Geographical segregation and significant environmental heterogeneity were observed between these two areas due to the existence of the Liaodong Peninsula and different levels of urbanization. There were significantly different regional species pools and biogeographic patterns for both bacterial and protistan communities between LH and YLJ coastal areas. The dominant drivers of differences in bacterial and protistan communities between the LH and YLJ coastal areas were variation in regional species pools and species turnover. Local community assembly mechanisms, including heterogeneous selection and dispersal limitation, played important roles in shaping the bacterial and protistan communities in a single-studied area.

Summary: This study investigated the generational effects of the antidiabetic drug MET on zebrafish and its nonexposed offspring. The results showed that MET had significant effects on reproductive-related parameters in zebrafish, with parental exposure to MET impacting critical molecular processes and upregulating male vtg1 expression, indicating an estrogenic effect. The nonexposed offspring also experienced negative effects on survival and growth due to parental MET exposure.

Summary: This review addresses the monitoring and evaluation of protein-bound uremic retention solutes in biological fluids, such as indole-3-acetic acid, indoxyl sulfate, p-cresol, and p-cresol sulfate, which have been associated with the development of kidney, cardiovascular, and bone toxicities. The review discusses conventional and advanced sample treatment procedures and chromatographic analytical methods for quantification of these compounds, with a particular focus on plasma, serum, and urine samples. There is a trend towards using liquid chromatography-tandem mass spectrometry for analysis, requiring protein precipitation, solid-phase extraction, and/or dilution prior to sample analysis. Miniaturized methods using microplate devices are recommended for sustainability.

Summary: For the first time, low force stereolithography is used to fabricate chemiluminescence flow-through cells, which outperform those produced through milling, blowing, or alternative 3D printing methods. Different cross-section geometries and customized gaskets and reactors are critically evaluated to enhance the analytical performance of the cells. A five-side polygon cell with Y-type confluence is found to be the most efficient in terms of reagent mixing and photon capture.

Summary: This research explores the use of a tubular membrane photoreactor for continuous titration of Fe2+ to enhance the Photo-Fenton process for the tertiary treatment of urban wastewater. The study shows that the PF-like process exhibits superior performance in removing contaminants compared to traditional PF process, especially for melamine. The PF-like process also has advantages in terms of higher residual concentrations of Fe2+ and lower precipitation of PO43-, making it a promising option for tertiary treatment.

Summary: This study describes an analytical method based on solid-phase extraction and liquid chromatography coupled to tandem mass spectrometry to monitor the occurrence of a group of seventeen pharmaceuticals in wastewater. The results showed that all studied pharmaceuticals were found in all samples, with concentrations ranging from non-detectable to 10,393 ng/L, and the highest concentrations were for tramadol. Furthermore, the study also found that the pattern of pharmaceutical use was generally similar in all cities monitored.

Summary: This study examined the occurrence and fate of 52 emerging contaminants in transnational river basins, coastal areas, and wastewater treatment plants in Portugal and Spain. The results showed that these contaminants were widely present and were only partially removed by conventional treatment processes. These findings highlight the need for significant upgrades and coordination of wastewater treatment plants to meet future EU regulations.

Summary: This review critically examines the current state-of-the-art of nanomaterial-based electrochemical sensors in flow injection (NBES-FI) platforms for in-line determination of environmental pollutants from 2013 to mid-2023. The synergistic effects of FI platforms and nanomaterial-based modifiers, such as metal nanoparticles and carbon-based nanomaterials, are discussed in detail, focusing on minimizing electrode fouling, alleviating overpotential, and boosting overall figures of merit. The impact of experimental parameters, including electrode properties and design, synthesis routes of nanomaterials, and electrochemical detection techniques, on the analytical performance of NBES-FI is thoroughly evaluated. Current challenges and the need for real-world implementation of NBES-FI in environmental settings are outlined, along with perspectives on integrating NBES-FI with microextraction approaches and utilizing 3D printing technology for customized fluidic platforms.
