The current knowledge about mercury cycling in the Adriatic is presented through an overview of the state of the art of research in this area: temporal and spatial distributions and occurrence of mercury species in seawater and sediment, and chemical transformations. We summarised research results of mercury speciation in order to describe its presence and fate in the Adriatic Sea. The Adriatic Sea represents a net source of mercury to the Mediterranean Sea due to the highest total mercury concentrations observed in the North Adriatic Sea and the highest methylmercury concentrations in the South Adriatic Pit. However, the biogeochemical cycle of mercury is not completely known and our understanding of mercury transport between compartments and its (bio)transformations is limited. Future research needs to focus on microbial and chemical processes of mercury transformations to improve our understanding of the impacts of mercury contamination on the environment and human health in the Adriatic Sea.","PeriodicalId":35248,"journal":{"name":"Acta Adriatica","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2019-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.32582/aa.58.1.14","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42297105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Market value with RF index of added value approaches were used to calculate economic gains and losses from RF. The consistency was observed with the high education levels, high expense and high market value for fishers in the Middle Black Sea provinces; Kastamonu, Samsun, Sinop and Ordu. In all provinces, the harvesting costs stayed far below the average market prices of target species. Also, positive values of RF index were observed in all provinces. The species catch composition in Western and Eastern provinces did not show great differences. Furthermore, even if the habitat type along the Black Sea coast of Turkey did not show great variations, in the Western provinces some certain species including T. trachurus, S. sarda, B. belone, P. saltatrix, M. cephalus were caught in higher amounts.
