As part of EEA's ongoing security and identity management improvements, we are currently migrating the system to Entra ID authentication.
We kindly ask all users to start using Entra ID credentials when logging in to the system. 

Please note that LDAP authentication will be phased out and disabled by the end of August 2026.
We encourage you to verify that you can successfully access the system and that your account and permissions function as expected after Entra ID login.
Should you encounter any issues or require assistance during this transition, please contact Laszlo Cseh at laszlo.cseh@eaudeweb.ro

Description parameter
From 2016 to 2021, the average litter on the sea coast was 336,7 ± 257.7 waste/100 m, with a median value of 309 litter/100 m. On average, 2016 to 2021 saw the lowest litter (227.8 ± 134.3 litter/100 m) and the highest litter in 2017 (481.3 ± 312.3 litter/100 m). No shore-based sampling of waste was carried out in 2021. The calculation of the directional trend for the period 2016-2021 yielded a negative coefficient from Theil Sen’s estimator (a=-2.5), indicating a negative trend in the occurrence or decline of litter on the coast.
No limit value has yet been established. The data show a decrease in the number of waste. However, from 2016 to 2021, the seabed was on average 43.5 ± 43.9 litter/km². During this period, the median value was 40 waste/km². In the period from 2016 to 2021, the lowest average was waste in 2020 (25.6 ± 33.4 waste/km²). On average, waste was the highest in 2017 (87.7 ± 54.6 waste/km²). No seabed litter sampling was carried out in 2016 and 2021.
No limit value has yet been established. The data show an increase in the number of waste. From 2016 to 2021, the surface layer of the sea’s water column had on average 241,7± 319.8 litter/km². No sampling was carried out within the 2016-2021 period in 2016, 2018 and 2021. On average, the lowest levels of waste were recorded in 2019 (203,6 ± 285.0 waste/km²). On average, the highest amount of waste in this period was in 2017 (268.6 ± 209.0 waste/km²).
No limit value has yet been established. The data show a decrease in the number of micro-litter. No sampling of micro-litter on the seashore was carried out in 2016, 2017, 2018 and 2021. As the methodology was updated in 2019, this report only showed data from 2019 onwards. In 2019, the average concentration of micro-litter in coastal sediment was 298.5 ± 221.6 micro-litter/kg dry sediment. In 2020, the lowest concentration of micro-litter in coastal sediment was found (100,0 ± 83.5 micro-litter/kg dry sediment).
No limit value has yet been established. The data show a decrease in the number of micro-litter. On average, the seabed was 306,2 ± 77.1 micro-litter/kg dry sediment from 2016 to 2021. In 2017, the seabed averaged 280.0 ± 165.6 micro-litter/kg dry sediment. In 2019, the average concentration of micro-litter in seabed sediments was 526.7 ± 239.2 micro-litter/kg dry sediment. The lowest concentrations of micro-litter on the seabed in 2020 were 111.9 ± 85.1 micro-litter/kg dry sediment. No sampling was carried out in 2018 and 2021.
No limit value has yet been established. The data show a decrease in the number of micro-litter. In the period from 2016 to 2021, it averaged 0.195 ± 0.126 particles/m². On average, the highest concentration of micro-litter in the surface layer of the water column was measured in 2017 (0,340 ± 0,129 particles/m²). During this period, on average, the lowest litter was in the surface layer of the 2019 water column (0.113 ± 0.077 particles/m²). On average, 0.134 ± 0.056 particles/m² were measured in 2020. No sampling was carried out in 2016, 2018 and 2021.

Description criteria
At the level of criterion D10C1, a comparison with the previous cycle indicates the maintenance or stability of the trend in the case of the amounts of litter in the surface layer of the water column and on the seabed, while the amount of litter on the coast indicates an improvement compared to the previous cycle (the previous positive trend became negative). Based on comparisons of the two cycles, trends show that the situation with D10C1 is improving, with negative trends predominating, suggesting a decrease in pollution.

At the level of criterion D10C2, the comparison with the previous cycle shows progress as the trend is negative and indicates a decrease in the quantities of waste in the surface layer of the water column. The comparison of seabed and coastal volume trends with the previous period was not made because a different methodology for sampling micro-litter in coastal sediment was applied in the previous cycle. Sampling of micro-litter on the seabed only started in 2017 as part of the pilot monitoring. There is a negative trend over the period 2016-2021, which means an improvement in the situation and a reduction in the amount of micro-waste across all parameters.

Podatki za merilo D10C3 so se zbirali v okviru neuradnega (pilotnega) monitoringa na območju morskih voda v pristojnosti R Slovenije. Zaradi relativno majhnega nabora podatkov in sporadičnega zbiranja le-teh je zanesljivost analiz primerno majhna, zato tudi ocene stanja po merilu D10C3 ni bilo mogoče izvesti.

In the previous assessment, the assessment of the state of the marine environment for D10 was based on the baseline values proposed under the Barcelona Convention and therefore a direct comparison of the situation with the previous cycle is not possible. At macro-waste level, the comparison with the previous cycle shows that the trend is maintained or stable in the case of waste quantities in the surface layer of the water column and on the seabed, while the amount of litter on the coast shows an improvement compared to the previous cycle (the previous positive trend became negative). Looking at the comparisons of the two cycles, trends show that the situation with regard to macro-waste is improving, with negative trends predominating, suggesting a decrease in pollution.

At the level of the macro-waste measure, a comparison with the previous cycle indicates that the trend is maintained or stable in the case of the quantities of plastic waste in the surface layer of the water column and on the seabed, while the quantity of plastic waste on the coast indicates a negative trend indicating an improvement and decrease of this type of pollution compared to the previous cycle (the previous positive trend became negative). Based on comparisons of the two cycles, trends show that the situation regarding quantities of plastic plastic macro-waste is improving.
