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.
