Towards a Regional Action Plan
- n Marine Litter in the Baltic Sea
Stefanie Werner (UBA, Germany) (UBA, Germany)
Info paper structure
- Background information
- Amounts, materials, items, sources of ML and data gaps
- Monitoring and common indicators
- Lines of thinking on measures and actions
Background
- Helsinki Convention: prohibition of dumping (Art. 11); prevention
- f pollution from ships (Annex V), incl. pleasure crafts
- Copenhagen Ministerial Declaration (2013): to develop a Regional
Action Plan (RAP) on Marine Litter (ML) by 2015 at the latest
- HELCOM 35/2014: to develop the RAP based on information on
sources & amounts of ML, aiming to define concrete and sources & amounts of ML, aiming to define concrete and adequate measures to minimize ML in the BS, two dedicated workshops (with wide stakeholder participation)
- HELCOM MONAS 19/2013 initiated an intersessional
correspondence activity on ML (ML expert network)
- Info paper + thematic session discussion = basis for Issue paper
for the 1st HELCOM RAP ML workshop (27-28 May, Helsinki)
Main sources of ML
- Coastal-based tourism and
recreation (from 33% to 58%)
- Household activities, incl.
sanitary waste (48%)
- Transport and waste
collection/dumping collection/dumping
- Fishing (ghost nets: 5.500-
10.000 per year)
- Microparticles from land-
based sources (e.g. fibres and road traffic )
Amounts
Parameter Amounts Reference
Beach litter From 75,5 items/100 m in rural beaches to 236,6 items/100 m in urban beaches Up to 700-1.200 items/100m near sources MARLIN 2013 HELCOM 2009 Litter on the sea floor 44-208 items/km2 Ocean Litter on the sea floor 44-208 items/km Ocean Conservancy/ICC 2002-2006 Floating litter 1,26 ± 0,82 items/ha Galgani et al. 2000 Microparticles in the water column 340 – 14.620 of >10µm fibres/m3 760 – 104.780 of >10µm non- fibres/m3 Noren and Magnusson (2010) KIMO (2007) Setälä et al.

Data gaps
- Amounts and consistency/composition, and transport,
- rigin and impacts of ML on the sea floor and in the
water column (floating litter, micro-particles)
- Input pathways of ML, especially regarding micro-
particles and inputs from rivers
- Importance of sanitary waste as ML source
- Long-term trend information
- Long-term trend information
- Transfer of toxic chemicals associated to micro-particles
- Toxicity and environmental impact of ML to the
ecosystem
- Socio-economic impact (cost) of ML
For consideration - sources
Addressing the right sources is key to achieve reductions of ML in the marine environment Aim: Achievement of a common understanding on predominant materials, items, sources and pathways of ML and data gaps:
- Are there additional information which should be included?

- Are there additional information which should be included?
- Evaluation on items causing most harm (ecological but also
socioeconomic) needed?
- Additional data gaps?
Potential common indicators
Monitoring protocol Information provided Data consistency Personnel & technical costs Beach litter (also meso litter) Floating litter Seafloor litter Seafloor litter Litter in biota (species?) Microlitter
Available protocols/methodologies
- Beach litter (also meso litter):
– TG ML – OSPAR beach litter monitoring – UNEP Guidelines – NOAA Guidelines – MARLIN = UNEP/IOC guidelines adapted to the BS. – MARLIN = UNEP/IOC guidelines adapted to the BS. – National approaches following different protocols: Estonia, Finland, Sweden (UNEP), Germany (OSPAR)
- Floating litter:
– TG ML: floating litter in the surface water column – Visual ship based observations (Poland and Germany) – Aerial surveys (Germany)
Available protocols/methodologies
- Seafloor litter:
– TG ML trawling protocol for continental margins (<800 m depth) – Based on: – ICES (IBTS, BITS and MEDITS) trawling sampling protocol and – ICES (IBTS, BITS and MEDITS) trawling sampling protocol and protocol for categorization of items – TG ML protocol for shallow coastal areas (<20m depth): underwater visual surveys with SCUBA/snorkeling applied to benthic fauna
Available protocols/methodologies
Litter in biota:
- TG ML: (i) litter ingested by sea-birds (petrels as
the fulmar); (ii) marine turtles; (iii) benthic and pelagic fish, (iv) plastic material in sea birds breeding colonies and associated mortality rates
- Additional aspects to follow up on: ingestion by
marine mammals (mainly secondary uptake marine mammals (mainly secondary uptake though prey), entanglement of stranded sea birds and marine mammals in litter (e.g. fishing nets)
- OSPAR: indicator for plastic particles in fish under
development, maybe linked to ICES monitoring on fish and shellfish diseases (SE & G – join forces)
Available protocols/methodologies
Microlitter:
- Recommendations by the TG ML, but no
standardized methods
- On-going research projects of microlitter
- On-going research projects of microlitter
in sediments, sea water and biota
- Visual analysis only possible down to
1mm, smaller size classes need analyses via FT-IR or Raman Spectroscopy

For consideration –common indicators/monitoring
Applying common indicators in a comparable approach (based on harmonized protocols) is key to predict for regional trends and to monitor the effectiveness of potential measures Aim: Define level of maturity of indicators (common vs candidate) and consider which of the protocols available are suitable for further use in BS
- Which indicators should be nominated as common/candidates?

- Which indicators should be nominated as common/candidates?
- What are the differences in protocols applied, which should be used in
a joined approach?
- Where should that work be done: CORESET II, marine litter network?
- Possible pilot projects – joint application of protocols and joints approach
to answer research questions?
Measures
Existing sea-based:
- MARPOL (Annex V and IV) Special Area for garbage and sewage
- Baltic Strategy for reception facillities for ship-generated wastes
- Recommendation 28E/10 on „no-special-fee“ extended to marine litter caught in
fishing nets Existing land-based:
- Over 40 HELCOM Recommendations: proper waste handling & limiting discharges
at source (industry, sewage, agriculture)
- Hot spots programme (1992-2012) – 109 out of 162 cleaned-up

- Recommendation 29/2 on beach litter monitoring
New/additional measures and actions should aim to:
- Enforce & fully implement existing requirements
- Close loopholes & emerging issues (microplastics)
- Prevent further introduction of ML in the Baltic Sea
- Remove existing litter and raise public awareness
- Focus on transbondary large-scale character
