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.
