Increasing population and expansion of urban areas are often associated with degradation of aquatic ecosystems. Although water quality is a major concern for worldwide authorities, several emerging contaminants can threaten long term status of aquatic ecosystems and human health. UV filters are widely used in industrial products such as plastics, paints and coatings, to enhance their photo protective properties. Personal care products, such as shampoos, body creams, make-up and sunscreens, used in humans’ daily routine, also comprise a wide variety of chemicals, such as organic UV filters and parabens. Some UV filters are persistent, bioaccumulative and toxic. Parabens prevent bacterial growth and extend products shelf-lives, but they can have endocrine disruption properties. Wastewater is a potential vehicle of UV filters and parabens to the aquatic ecosystems, where they tend to accumulate in suspended sediments. This study investigates the presence of organic UV filters and parabens in Ribeira dos Covões peri-urban catchment, in central mainland Portugal. The catchment has been deeply urbanized over the last decades, due to its proximity to Coimbra city center. Urban areas cover 40% of the catchment land-use and include several health services, such as a hospital, and a relatively large pharmaceutical company. Wastewater is piped and transported into a treatment plant (WWTP) located outside the catchment. The sewer system, however, is sometimes subject to failure, leading to leakages which affect local streams. In September 2018, fluvial sediment samples (0-3 cm depth) were collected in 10 sites across Ribeira dos Covões stream network. The freeze-dried sediment samples were extracted using an accelerated solvent extractor (ASE-350, DIONEX, Germany) method, and analysed for 17 UV filters, 5 parabens and 2 synthetic musks, using an Agilent UHPLC-MS/MS system operating with dopant-assisted atmospheric pressure photoionization (DA-APPI). The results show the presence of methylparaben (10.3 ng/g dw) at the catchment outlet. UV filters were found in sediments from several sites in Ribeira dos Covões. Compounds revealing highest concentrations were octocrylene, quantified in 8 of the 10 sampling sites and reaching 286.3 ng/g dw, and ethylhexyltriazone, quantified in half of the monitored sites in concentrations up to 67.7 ng/g dw. The largest number of compounds and with highest concentrations, were recorded in two stream sections that received wastewater, based on reports from local citizens about sewer pipe leakages. Wastewater contamination can represent a major problem for the good status of aquatic ecosystems in urban environments.

Environmental contextPersonal care products containing organic chemicals to filter the sun’s UV rays are produced and used on a broad scale worldwide. Consequently, these organic UV filters are now widespread in the environment. We investigate the occurrence of seven common organic UV filters in river and lake sediments thereby providing valuable data for the future environmental risk assessment of these chemicals to the benthic community of freshwater ecosystems. AbstractPersonal care products (PCPs) are produced and used in huge amounts. These formulations are permanently introduced into the aquatic environment during regular use, mainly through municipal sewage treatment plants. Although there is increasing concern about PCP residues in the aquatic environment, little is known about the extent and level of contamination. The occurrence and concentrations of the seven most frequently used ultraviolet (UV) filters in river and lake sediments have been investigated over a 6-month period by gas chromatography–mass spectrometry: benzophenone-3 (BP-3), 3-benzyliden camphor (3-BC), butyl-methoxydibenzoylmethane (B-MDM), ethylhexyl dimethyl p-aminobenzoic acid (ED-PABA), ethylhexyl-methoxycinnamate (EHMC), 3′-(4′-methylbenzyliden)camphor (4-MBC) and octocrylene (OCR). B-MDM, EHMC and OCR were identified as major contaminants. They were present in every sediment sample with maximum concentrations of 62.2, 6.8 and 642 µg kg–1. 3-BC and ED-PABA could not be detected in any sediment sample. The temporal distribution profile and concentrations of UV filters differed between lakes and rivers. Whereas concentrations of all UV filters in river sediments were low and constant over time, lake sediments exhibited high UV-filter levels during summer and concentrations dropped in autumn. These findings support risk assessment activities and contribute to a better understanding of the magnitude of contamination with organic UV-filter substances in aquatic ecosystems.

Cyanotoxins (CTs) produced by cyanobacteria in surface freshwater are a major threat for public health and aquatic ecosystems. Cyanobacteria can also produce a wide variety of other understudied bioactive metabolites such as oligopeptides microginins (MGs), aeruginosins (AERs), aeruginosamides (AEGs) and anabaenopeptins (APs). This study reports on the co-occurrence of CTs and cyanopeptides (CPs) in Lake Vegoritis, Greece and presents their variant-specific profiles obtained during 3-years of monitoring (2018–2020). Fifteen CTs (cylindrospermopsin (CYN), anatoxin (ATX), nodularin (NOD), and 12 microcystins (MCs)) and ten CPs (3 APs, 4 MGs, 2 AERs and aeruginosamide (AEG A)) were targeted using an extended and validated LC-MS/MS protocol for the simultaneous determination of multi-class CTs and CPs. Results showed the presence of MCs (MC-LR, MC-RR, MC-YR, dmMC-LR, dmMC-RR, MC-HtyR, and MC-HilR) and CYN at concentrations of <1 μg/L, with MC-LR (79%) and CYN (71%) being the most frequently occurring. Anabaenopeptins B (AP B) and F (AP F) were detected in almost all samples and microginin T1 (MG T1) was the most abundant CP, reaching 47.0 μg/L. This is the first report of the co-occurrence of CTs and CPs in Lake Vegoritis, which is used for irrigation, fishing and recreational activities. The findings support the need for further investigations of the occurrence of CTs and the less studied cyanobacterial metabolites in lakes, to promote risk assessment with relevance to human exposure.

Abstract Organic UV-filters, including 4-hydroxybenzophenone (4-HBP) and 2,4-dihydroxybenzophenone (BP-1), are persistent emerging contaminants whose presence in the environment poses a threat to aquatic organisms due to their endocrine disruptor’s properties. For this reason, finding suitable technological processes for their safety and efficient removal from the environment represent a priority for the scientific community. To the author’s knowledge, until now, there are no studies reporting the biodegradation of 4-HBP and BP-1 by a single bacteria strain. In this paper, there were tested the 4-HBP and BP-1 biodegradation potential of two Gram-positive (Staphylococcus aureus and Enterococcus faecalis) and two Gram-negative (Salmonella typhimurium and Serratia rubidae). The 4-HPB biodegradation process was observed only in the presence of Gram-negative bacterial strains. Thus, the biodegradation rates of 4-HBP reached up to 12.7% after 24h of incubation in presence of Salmonella thyphimurium and up to 24.0% after 24h of incubation with Serratia rubidae. Staphylococcus aureus was able to biodegrade 26.7% of BP-1, while Salmonella thiphymurium was able to biodegrade 14.7% of BP-1 after 24h of incubation. Their biodegradation products generated during the 4-HBP biodegradation process by Serratia rubidae were analyzed through LC-MS/MS analysis. The (bio)degradation products were benzophenone and a multi-hydroxylated derivative of 4-HBP and the degradation pathways were proposed. The data obtained in this study gave important information regarding the 4-HBP and BP-1 potential biodegradation by single bacterial strains.
