چکیده انگلیسی
Between 2014 and 2016 a total of 43 microplastic samples were collected at six sampling stations in the eastern section of the Gulf of Lion (located in the northwestern Mediterranean Sea), as well as upstream of the Rhône River. Microplastics were found in every sample with highly variable concentrations and masses. Concentrations ranged from 6â¯Â·â¯103 items kmâ2 to 1â¯Â·â¯106 items kmâ2 (with an average of 112â¯Â·â¯103 items kmâ2), and mass ranged from 0.30â¯gâ¯kmâ2 to 1018â¯gâ¯kmâ2 DW (mean 61.92â¯Â±â¯178.03â¯gâ¯kmâ2). The samples with the highest and lowest microplastic count originate both from the Bay of Marseille. For the Bay of Marseille, it is estimated that the total microplastic load consist of 519â¯Â·â¯103 -101â¯Â·â¯106 items weighing 0.07-118â¯kg. Estimations for daily microplastic transport by the Northern Current and the Rhône River, two important hydrologic features of the northwestern Mediterranean Sea, range from 0.18 to 86.46â¯t and from 0.20 to 21.32â¯kg, respectively. Particlesâ¯<â¯1â¯mm2 clearly dominated sampling stations in the Northern Current, the Rhône River and its plume (52, 53 and 61%, respectively), suggesting a long exposure time in the environment. Items between 1â¯mm2 and 5â¯mm2 in size were the most abundant microplastics in Marseille Bay (55%), which suggests coastal pollution sources or the removal of smaller particles from surface waters e.g. by ballasting owing to the presence of epibionts.
