Occurrence and ecological risk assessment of organic UV filters in coastal waters of the Iberian Peninsula

Marine Pollution Bulletin, Journal Year: 2023, Volume and Issue: 196, P. 115644 - 115644

Published: Nov. 1, 2023

This study aimed to assess the presence of 21 UVFs and metabolites in coastal regions Iberian Peninsula, evaluate their environmental risk, identify possible influential factors affecting measured concentrations. Sampling was carried out spring summer seasonal variations. were detected 43 46 sampling sites. Only 5 found above LOD: BP4, OC, BP3 BP1 BP8. Samples collected Mar Menor had greatest variety compounds per sample highest cumulative The risk characterized using Risk Quotients (RQ). showed a Low 2 sites while for OC RQ indicated Moderate 22 points. variables that contribute most variation are population density, season, whether it an open bay or not, level urbanization. WWTPs lower influence.

Biochemical responses of the mussel Perna perna after exposure to environmental concentrations of the UV filter Benzophenone-3

Xenobiotica, Journal Year: 2023, Volume and Issue: 53(4), P. 309 - 319

Published: April 3, 2023

AbstractAbstractPersonal care products, such as UV filters, are frequently present in aquatic ecosystems, but studies on their impact marine organisms still scarce. Here we addressed the effects of benzophenone-3 (BP-3) antioxidant status Perna perna mussels exposed to concentrations 0.1 and 3 μg.L−1 for 72 h 7 days. Glutathione peroxidase (GPx), glutathione reductase (GR), S-transferase (GST), glucose-6-phosphate dehydrogenase (G6PDH) activity lipoperoxidation (MDA) were evaluated gills. A significant reduction (p < 0.05) G6PDH GPx was observed after exposure days µg.L−1. However, no differences GST MDA levels, independently time. Principal component analysis (PCA) showed an association BP-3 highest concentration with GR at only exposure. Similarly, integrated biomarker response (IBR) demonstrated alterations. In conclusion, environmentally relevant altered auxiliary enzymes, which could cause long-term damage P.perna mussels. The need implement more efficient techniques wastewater treatment systems is pointed out, especially summer, when filters used abundantly.Keywords: Oxybenzonebiomarkersbivalveoxidative stresssunscreen AcknowledgementsThe authors grateful 'Coordenação de Aperfeiçoamento Pessoal Nível Superior - CAPES' scholarship Gabriel S.

Sunscreen pollution is abated during the COVID-19 “Anthropause” of 2020 in two U.S. National Parks: Cape Lookout National Seashore and Kaloko-Honokōhau National Historical Park

Journal of Sea Research, Journal Year: 2024, Volume and Issue: 200, P. 102510 - 102510

Published: June 7, 2024

From March to June 2020, governments across the world imposed lockdowns in an attempt reduce transmission of COVID-19 during early phase pandemic. This period time which human activity slowed worldwide has been coined "Anthropause". The goal this study was determine if sunscreen pollution abated Anthropause and identify severity when tourism/recreation recovered at two coastal units U.S. National Park System: Kaloko-Honokōhau Historical Hawaiʻi, U.S.A. Cape Lookout Seashore North Carolina, Active ingredients products were measured water sand samples both locations, including oxybenzone, octinoxate, octocrylene, octisalate, homosalate, relevant breakdown some these ingredients. A risk assessment conducted on post-Anthropause contaminant levels for locations there a threat reduction Anthropause, whether tourism recovery served as wildlife. Both national park exhibited almost absolute contamination period, striking commonality considering geographic expanse separating parks. Once travel restrictions lifted, large influx tourists ensued resulting relatively sudden dangerous increase chemical pollution. supports argument that unmanaged is source poses localized continuity species populations biodiversity, especially coral reefs fisheries.

Abstract Background Biogeography has been linked to differences in gut microbiota several animals. However, the existence of such a relationship fish is not clear yet. So far, it seems depend on species studied. most studies microbiotas are based single populations. In this study, we investigated from three wild populations two-banded sea bream Diplodus vulgaris (Geoffroy Saint-Hilaire, 1817) determine whether its diversity, structure and potential functionality reflect geographic origin fish, at large small geographical scale. Additionally, explored host- environmental-related factors explaining relationship. Results We showed that taxonomy mucosa-associated differ varying degrees depending spatial scale considered. At scale, observed both taxonomical differed significantly between contrast, diversity microbial community displayed significant with other than (i.e. sampling date).

The adverse effects of solar ultraviolet radiation (UVR) on normal skin are well established, especially in those with poorly melanized skin. Clinically, these may be classified as acute, such erythema or chronic keratinocyte and melanocyte cancers. Apart from type genetics, clinical responses to UVR dependent geophysical (e.g., intensity) behavioural factors. latter important because they result 'solar overload' unwanted consequences ever greater burdens healthcare systems. Correctly used, sunscreens can mitigate the acute exposure. Laboratory studies also show that inhibit initial molecular cellular events responsible for outcomes.
