“…Nevertheless, compared with some recent studies on beach litter, the average densities on the Galician coast seem to be lower than in tourist areas of the Mediterranean (3600 BLI per 100 m; Martinez-Ribes et al 2007), the Black sea (2400 BLI per 100 m; Topçu et al 2013) and populated areas of Brazil (500 to 10000 BLI per 100 m; Tourinho and Fililman 2011). Comparisons with other studies in the Atlantic show that our average values are very similar to those reported for England (85 BLI per 100 m; Willoughby et al 1997) and the US Atlantic coast (72 BLI per 100 m; Ribic 1998) and very close to those of the North Atlantic (66 BLI per 100; Barnes and Milner 2005).…”

Summary:In order to assess the situation of beach litter on the Galician coast (NW Spain), we conducted a seasonal series of sampling on three beaches: A Lanzada, Baldaio and O Rostro. A total of 79 surveys were conducted from 2001 to 2010 on a stretch of 100 m and a stretch of 1 km. A total of 37862 beach litter items were counted and classified on the 100-m stretch and 7845 on the 1-km stretch. The average annual value of litter items for the 100-m beach stretch was 1016±633, 88±31 and 332±183; for the 1-km stretch, the average value of litter items was 163±87, 42±31 and 81±38, for A Lanzada, Baldaio and O Rostro beaches, respectively. The most common element found in beach litter was made of plastic, with average percent of 63, 38 and 83 for A Lanzada, Baldaio and O Rostro, respectively. We found that the main source of beach litter was the fishing and aquaculture sector, with an average percent value of 23, 14 and 38 for A Lanzada, Baldaio and O Rostro, respectively. Keywords: beach litter; types; sources; Galician coast; NW Iberian Peninsula. Características de basuras (abundancia, tipo y origen) en playas de la costa gallega (2001-2010)Resumen: Con el fin de evaluar la situación de las basuras marinas en playas de la costa de Galicia (noroeste de España) se realizó una serie de muestreos estacionales en tres playas: A Lanzada, Baldaio y O Rostro. 79 muestreos se llevaron a cabo desde 2001 hasta 2010 en tramos de playas de 100 metros y 1 km. 37862 elementos fueron contados y clasificados en el tramo de 100 metros y 7845 en los estudios de 1 km. El valor promedio anual de basuras por cada 100 m de playa fue 1016±633, 88±31 y 332±183; en los muestreos de 1 km de playa, el valor medio fue de 163±87, 42±31 y 81±38, para A Lanzada, O Baldaio y Rostro, respectivamente. El elemento más común que se encuentra en la basura de la playa se compone principalmente de plástico con un porcentaje promedio de 63, 38 y 83 en A Lanzada, Baldaio y O Rostro, respectivamente. Se encontró que las principales fuentes de basura en playa son la pesca y la acuicultura, con un porcentaje promedio de 23, 14 y 38 en A Lanzada, Baldaio y O Rostro, respectivamente.

“…Data expressed as items m −2 or larger areas are more convenient for comparisons. Most studies have reported densities in the m −2 range ( Topçu et al 2013). Data expressed as quantities per linear distance are more difficult to compare because the results depend on beach size/width.…”

“…Data expressed as quantities per linear distance are more difficult to compare because the results depend on beach size/width. Plastic accounts for a large part of litter on beaches from many areas with up to 68 % in California (Rosevelt et al 2013), 77 % in the south east of Taiwan (Liu et al 2013), Eriksson et al (2013) 86 % in Chile (Thiel et al 2013), and 91 % in the southern Black Sea (Topçu et al 2013). However, other types of litter or specific types of plastic may also be important in some areas, in terms of type (Styrofoam, crafted wood) or use (fishing gear).…”

Marine debris is commonly observed everywhere in the oceans. Litter enters the seas from both land-based sources, from ships and other installations at sea, from point and diffuse sources, and can travel long distances before being stranded. Plastics typically constitute the most important part of marine litter sometimes accounting for up to 100 % of floating litter. On beaches, most studies have demonstrated densities in the 1 item m −2 range except for very high concentrations because of local conditions, after typhoons or flooding events. Floating marine debris ranges from 0 to beyond 600 items km −2 . On the sea bed, the abundance of plastic debris is very dependent on location, with densities ranging from 0 to >7700 items km −2 , mainly in coastal areas. Recent studies have demonstrated that pollution of microplastics, particles <5 mm, has spread at the surface of oceans, in the water column and in sediments, even in the deep sea. Concentrations at the water surface ranged from thousands to hundred thousands of particles km −2 . Fluxes vary widely with factors such as proximity of urban activities, shore and coastal uses, wind and ocean currents. These enable the presence of accumulation areas in oceanic convergence zones and on the seafloor, notably in coastal canyons. Temporal trends are not clear with evidences for increases, decreases or without changes, depending on locations and environmental conditions. In terms of distribution and quantities, proper global estimations based on standardized approaches are still needed before considering efficient management and reduction measures.

“…Survey was not carried out if the conditions were unfavorable or beach sand was covered by ice/ snow. The classification of the BML was done according to the list provided in OSPAR guidelines (OSPAR, 2010) and expert judgement based on the UNEP guidelines (Cheshire et al 2009) and Eda et al (2012) research. This was done in order to associate the litter to the different possible functional use and/or source.…”

The first attempt to investigate the marine litter pollution level of the Lithuanian coastal zone was carried out based on different marine litter monitoring methods and according to the lists of identifiable items. The results have proven that plastic is the dominant type of marine litter. It seems that tourism and fishery related marine litter occurrence do not significantly depend on seasonal variations. The outcome of the study will serve as basic information for future inventory of the character of marine pollution, provide the scientifically grounded limit value for Good Environmental Status (GES) assessment in the Lithuanian coastal zone, and will contribute for the enhancement of the ecological status of the south-eastern coasts of the Baltic Sea. Keywords • marine litter • plastics in marine environment • good environmental statusArūnas Balčiūnas (arunas.balciunas@corpi.ku.lt), Nerijus Blažauskas,
