Theresults of the project provide a very good overview of marine litter pollution of the north-easternAtlantic. The results of the project demonstrate that total litter pollution levels in the OSPAR regionas a whole have remained stable at a high level during the project period 2000-2006.Significant increases or decreases in litter levels were not found at the regional level; however,small non-significant increases in the total amount of litter were recorded for the Southern NorthSea and the Iberian Sea regions from 2003 onwards.The analysis of the occurrence of litter items which function as indicators for different sources oflitter pollution, indicate that litter pollution originating from fisheries and aquaculture activitiesincreased significantly in the north-eastern Atlantic in the project period. The analysis of theoccurrence of indicator items for other sources (”non-operational litter from shipping, fisheries andoffshore installations”/“operational litter from shipping and offshore installations”/”sanitary andsewage”/”tourism and recreation”) did not detect any trends over the project period.With the exception of a significant decrease in the number of large litter items on the 1 km surveysites, no reduction in the number of litter items found on beaches was found in the period 2000-2006.The proportion of plastic litter items in the total amount of litter found on beaches in the OSPAR-Region is very high, although the disposal of plastic litter from ships has been prohibited worldwidesince 1988. Three quarters of the litter items registered during the project were made of plastic.The proportion of plastic litter items in the total amount of all items found on the survey beachesincreased significantly during the project period from 68% in 2001 to 78% in 2006.118
