Data from Baltic seabed trawls (during the study period (2018-2023) for 72 times in Lithuanian marine waters, BAL-LT-AA-03) showed that at least one marine litter was detected in 61 trawls (84.7 %). The amount of litter detected varied between 1 and 30 units during the survey period or, when converted per unit area, between 0.72 units/km² and 23.5 units/km². The highest number of items found at trawling sites was between 1 and 10. Criterion 1.3 – Average annual amount of litter accumulating on the bottom per km² – 1 unit and the trend shows an improvement, GES has not been achieved.

Litter (except micro-litter) on the Lithuanian Baltic Sea coast (BAL-LT-AA-04) was monitored on ten beaches. The observations identified all beach litter present in the 100 m research transect and assessed different items of coastal litter. An assessment of coastal litter by type of material shows that debris from artificial polymer materials dominated the total amount of litter (around 85 % of the total). This ratio was close to the last period’s estimate of 83 % of the total amount of litter (2012-2016 data). The relative amount of paper and cardboard debris has increased compared to the previous period (5.5 % in the reference period and 0.9 % in the previous period of the total amount of debris); glass/ceramics (1.2 % in the reporting period, 4.0 % in the previous period) and metal litter (2.5 % in the reporting period, 5.0 % in the previous period). On average, 105 items of litter per 100 m of beach were found on beaches. Most of them were found on Palanga beach, inside. 176 units/100 m, with the minimum on Nida beach being inside. 49 units/100 m. Litter is most frequently detected as cigarette butts. The GES value was not achieved at any of the survey sites (0 %), although the trend in terms of values is improving.
