The data of the Baltic Sea bottom trawls (during the research period (2013-2017) 47 times in Lithuanian marine waters, BAL-LT-AA-03) showed that at least one litter polluting the marine environment was detected during 36 trawls (76.5% of all) . Comparing the composition of the found rubbish, it was found that artificial polymer materials (36.7%) dominated. The highest amount of litter during one trawl was recorded on the slopes of the Gotland and Gdansk basins (346.2 units / km2). The indicator of the criterion is the average annual amount of garbage accumulating on the bottom per 1 km2 - 1 unit. and the trend is non-rising (GES), the goal is to reduce the amount of litter polluting the seabed to less than 22 units / km2. GES is not reached in the marine area (0 percent of the area).

Litter (excluding micro-litter) polluting the Lithuanian Baltic Sea coast (BAL-LT-AA-04) was observed on ten beaches. During the observations, all beach-polluting litter in the 100 m long research transect was identified, and different coastal litter objects were assessed and assessed. Observational data show that artificial polymer materials: plastic fragments (41.8 ℅), cigarette butts (13.9 ℅), plastic ropes / purse sections (5.7 ℅) are the most common objects on the Lithuanian Baltic coast. Assessing the annual amount of litter polluting the coast, there is a downward trend in the total amount of litter. The GES value was not reached at any of the study sites (0 percent). Target values ​​have been set for the criterion indicator: the average annual amount of rubbish discharged ashore and accumulating at the shoreline is 57 units per 100 m of the beach section, the trend is non-rising (GES), the goal is to have less than 94 units per 100 m of beach sections on average. garbage.
