However, only a very low number of VMPs are available for use in aquaculture systems. In addition, the environmental risk potentially emanating from the use of these products has gained increased attention in the last years. In this context, the present review represents an in-depth analysis of the current two-tiered (phase I and phase II) approach for the environmental risk assessment (ERA) of VMPs mandatory in the European Union and the European Economic Area (EU/EEA), and its applicability to medicinal products intended for use in aquaculture. The following conclusions are drawn: (i) the current regulatory guidance documents detailing the phase I and II ERA procedure should be updated and harmonised across Member States and simple approach(es) applicable to the assessment of the environmental exposure of VMPs intended for use in aquaculture facilities should be devised; (ii) current and future regulatory guidance documents detailing the phase II ERA procedure for VMPs intended for use in aquaculture should comprise advanced mathematical models suitable for addressing different exposure scenarios relevant across the whole EU/EEA (including scenarios addressing the exposure of VMPs to agricultural soils from fish sludge); and (iii) it is recommended that any updates of relevant ERA guidelines clearly detail the types of studies needed to determine potential adverse effects of VMPs used in aquaculture on non-target organisms. Furthermore, the application of risk mitigation measures tailored to the reduction of the environmental exposure of VMPs on an individual aquaculture farm level should be considered in any future or updated guideline. Finally, it is anticipated that the present analysis of the main drawbacks surrounding the current ERA regulatory framework will help competent authorities to harmonise and facilitate the approval process for VMPs intended for use in aquaculture.</p>","PeriodicalId":546,"journal":{"name":"Environmental Sciences Europe","volume":"33 1","pages":""},"PeriodicalIF":5.9,"publicationDate":"2021-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4614364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The adult species occupy a high trophic position; therefore, significant levels of the hazardous substances tend to bioaccumulate in their tissues. However, the ability of the species to inhabit a wide range of feeding ground raises concerns about the adequacy of monitoring data in relation to the representativeness of measured levels of Hg at specific locations. Accounting for the migratory characteristics of this species can shed light on the origin of the analyzed specimens and thus trace Hg uptake chain. Perch samples and potential perch prey were collected at three remote stations in a fully interlinked system river–lake–coastal/transitional waters of the Gulf of Riga. Total mercury (THg) concentration and stable isotope ratios were measured in each sampled item. The perch data were divided into three subgroups associated with specific feeding grounds and one mixed group. A Bayesian mixing model was implemented to quantify the feeding preferences of each group, and based on the results, influence of each food source on Hg uptake by perch was modeled by means of Gaussian GAM model.</p><p>Calculated carbon and nitrogen stable isotope values demonstrated clear evidence of perch specimens migrating between the sampling stations. Substantial proportion of specimens sampled in river and lake stations had isotopic signals consistent with feeding in the gulf. The group of perch associated with feeding in the river grounds exhibited the highest THg concentrations with mean value of 209?μg?kg^?1 wet weight. The food items <i>C. harengus membras</i> and Crustacean showed significant mitigating effects on THg concentration. The rest of the food items showed a secondary influence on the variation of THg concentration.</p><p>The study clearly showed that the high mobility of perch along associated aquatic systems has a noticeable effect on Hg concentrations measured in the fish. Therefore, trophic position and isotopic signatures, along with identification of the food sources, can serve as important supplementary tools for more accurate data interpretation of Hg accumulation.</p>","PeriodicalId":546,"journal":{"name":"Environmental Sciences Europe","volume":"33 1","pages":""},"PeriodicalIF":5.9,"publicationDate":"2021-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1186/s12302-021-00523-w","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4342423","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
