From August 26–28, 2025, Świnoujście will become the center of the international BALEX DELTA 2025 exercise, dedicated to combating marine pollution. The Maritime Search and Rescue Service in Poland is the main organizer of the event, while the West Pomeranian Voivodeship Office is responsible for coordination of the land portion.

The exercise scenario involves a collision of vessels in the Baltic Sea, resulting in a fuel spill and water contamination. Some of the pollution ends up on the beach between Świnoujście and Międzyzdroje, contaminating a section of the coast and the birds nesting along the shore.

Nearly 400 people representing services, inspections, and organizations from Poland, Denmark, Estonia, Finland, Lithuania, Germany, and Sweden will participate in the exercise. Dozens of vessels, as well as rescue and environmental teams, will be involved.

About BALEX DELTA

The annual international marine pollution response exercise in the Baltic Sea, BALEX, is held in accordance with the 1992 Convention on the Protection of the Marine Environment of the Baltic Sea Area (the Helsinki Convention). The Convention mandates cooperative responses and preparedness among the Baltic Sea States for large-scale accidents.

The general objective of the BALEX exercises is to ensure that every Contracting Party is able to lead a major response operation.

BALEX exercises are hosted by the Contracting Parties according to a schedule agreed on by the HELCOM Response Working Group. BALEX has been held every year since 1989.

The HELCOM Stakeholder Conference 2025, a one-day online event dedicated to discussing hazardous substances in the Baltic Sea, will take place on 31 March 2025, from 10:00 to 16:00 EEST. Under the theme of the ‘One Baltic’ approach, the conference will explore the latest advancements in applying a holistic approach to managing hazardous substances to ensure a cleaner and healthier Baltic Sea.

The event is open to everyone, but pre-registration is required. Registration for this event has now closed.

The conference aims to bring together stakeholders from HELCOM Contracting Parties, industry representatives, NGOs, international organizations, civil society groups, and other interested individuals to discuss key actions supporting the Baltic Sea Action Plan (BSAP) goal: ‘A Baltic Sea unaffected by hazardous substances’.

The discussions will focus on implementing BSAP actions and the upcoming Regional Action Plan on Hazardous Substances (RAP HAZ), set to be finalized in 2025. Key topics include the current state of hazardous substances in the region, the impact of PFAS regulations, the risks associated with pharmaceuticals in the Baltic Sea, and the importance of a holistic regional approach to managing hazardous substances.

After several years in the making, HOLAS 3 thematic assessments on the state of the Baltic Sea have been published, covering the period of 2016–2021. The thematic assessments are part of the third HELCOM holistic assessment (HOLAS 3), providing a holistic view of the Baltic Sea ecosystem health. 

The holistic approach highlights the interconnectedness of various environmental factors and their impact on the ecosystem. The five assessment reports each focus on a specific topic, addressing the state of biodiversity, environmental pressures, eutrophication, and the relationship between humanity and nature. The findings offer valuable insights for policymakers, scientists, and stakeholders alike.

The results of HOLAS 3 have been published in stages, commencing in March 2023, and the process will culminate in the publication of the summary report State of the Baltic Sea, expected at the end of October 2023.

A comprehensive holistic assessment on the state of the Baltic Sea is conducted once every six years. The reports result from collaborative efforts among HELCOM member states, scientific experts, and organizations dedicated to the protection of the Baltic Sea. They serve as a cornerstone of HELCOM’s work and policymaking, assisting in the monitoring of the implementation and the effectiveness of the Baltic Sea Action Plan (BSAP).

The annual international Baltic Sea pollution response exercise BALEX 2023 is set to take place in the Gulf of Riga and its coastal region from 30 August to 1 September 2023.

The exercise aims to test the coordinated operation of the Baltic Sea response fleet units in addressing pollution incidents at sea. It will involve 11 military and civilian vessels from eight Baltic Sea countries: Denmark, Estonia, Lithuania, Poland, Finland, Germany, Sweden, and Latvia. These vessels are equipped with specialized pollution recovery equipment.

The coordination of BALEX rotates annually between the Baltic Sea states, and this year the exercise is organised by the State Environmental Service of Latvia, in cooperation with the Latvian National Armed Forces Coast Guard Service, and the State Fire and Rescue Service.

The participating Baltic Sea states’ agencies responsible for pollution response are aiming to enhance cooperation and communication among vessels carrying out the recovery of oil pollution at sea, examine the use of oil recovery equipment for shoreline the pollution incidents and the involvement of volunteers in rescuing animals.

BALEX 2023 will commence with a table-top simulation of an accident involving hazardous and noxious substances. The scenario is based on an actual accident where the engine room of a container ship caught fire  near the Latvian coast in the Gulf of Riga.

During the second day of the exercise, practical drills will focus on an oil pollution accident and mitigating its impact in the Gulf of Riga and on the coast north of the port of Skulte. The scenario entails a fictional oil tanker grounding in the Gulf of Riga, leading to the spillage of diesel fuel, heavy fuel oil and marine fuel.

In parallel with BALEX on 31 August 2023, the Multipurpose Maritime Operation (MMO) led by the European Maritime Safety Agency (EMSA), which has been taking place in the central and eastern part of the Baltic Sea will be completed.  

The annual international marine pollution response exercise in the Baltic Sea BALEX is held in accordance with the 1992 Convention on the Protection of the Marine Environment of the Baltic Sea Area (the Helsinki Convention). This convention mandates cooperative responses and preparedness among the Baltic Sea States for large-scale accidents. The BALEX exercise has been held every year since 1989.

To improve on the quality of monitoring data in the Baltic Sea, an intercalibration of analyzing methods of nutrients and heavy metals was recently carried out involving 22 laboratories across the region. The results were published in a report.

Financed by HELCOM, the intercalibration was carried out by the Danish Centre for Environment and Energy (DCE) of Aarhus University, on behalf of the HELCOM Pollution Load Compilation (PLC-8) project.

“For accurate Baltic-wide assessments of nutrient and metal concentrations, intercalibration between laboratories is crucial as it guarantees the compatibility of reported data, basically allowing us to compare apples with apples,” said Dmitry Frank-Kamenetsky, the coordinator of the HELCOM Pollution Load Compilation (PLC) projects. 

HELCOM now regularly organizes intercalibration campaigns at the beginning of each PLC project, to assure compatibility of reported data regarding nutrients and heavy metals. The latest campaign was already the third of its kind.

“The more we intercalibrate, the better data we get,” said Frank-Kamenetsky. “The good results of the recent intercalibration exercise confirm the trend of a continuous improvement of environmental monitoring data produced by the HELCOM countries.”

Marine litter and underwater noise topped the agenda of PRESSURE 14-2021, the meeting of the HELCOM Pressure Working Group dealing with pressures on the Baltic Sea, and which was held online from 13 to 16 April 2021. 

A revised full version of the HELCOM Regional Action Plan on Marine Litter (RAP ML) was presented at PRESSURE 14-2021. Based on the initial plan that was adopted in 2015 and incorporating the lessons learnt from all previous implementation efforts, the updated version is due to be adopted in October 2021 during the HELCOM Ministerial Meeting 2021, alongside the new Baltic Sea Action Plan (BSAP). 

PRESSURE 14-2021 further recognized the successful implementation of some of the actions under the current RAP ML, notably on including HELCOM guidelines on marine litter in national and local waste prevention and waste management plans, as well as sharing best practices on waste management. 

Other completed actions under the RAP ML include the development of best practices on the disposal of scrapped pleasure boats and handling of expanded polystyrene, the identification of key practical aspects of prevention of litter, and the retrieval and the management of ghost nets, among others. 

On underwater noise, a factor affecting species that are reliant on hearing, such as harbour porpoises, seals and some species of fish, wide support was expressed for the draft Regional Action Plan on Underwater Noise that is currently under development. The plan is due to be adopted with the BSAP later this year, along with an accompanying HELCOM Recommendation.

PRESSURE 14-2021 further developed recommendations on the regional policy document on hazardous substances that provides guidance on the upcoming HELCOM framework for hazardous substances. The framework is being developed to provide a more efficient and future-proof response to threats to the marine environment stemming from hazardous substances, especially from new chemicals. 

During the meeting, the topics of physical damage to the seafloor, the next HELCOM holistic assessment (HOLAS III), the update of the Baltic Sea Action Plan, eutrophication and issues pertaining to nutrients such as the Nutrient Recycling Strategy and the HELCOM framework on internal nutrient load management were also discussed. 

The meeting was attended by all HELCOM Contracting Parties and observers from Coalition Clean Baltic (CCB), Baltic Farmers’ Forum on Environment (BFFE), the Federation of European Aquaculture Producers (FEAP), European Federation of National Associations of Water and Wastewater Services (EurEau), Race for the Baltic, and John Nurminen Foundation, as well as by invited guest from Baltic Nest Institute (BNI) and the City of Helsinki.

Attended by about 400 people in person and several hundred more online, the XXI International Environmental Forum “Baltic Sea Day” was held from 23 to 24 March 2021 in Saint Petersburg, Russia as a hybrid event, with a main focus on the Baltic Sea Action Plan (BSAP), both on its current achievements and its now imminent update.  

“The BSAP remains one of the most effective instruments for achieving the HELCOM environmental objectives, offering a long-term vision and strategic orientation for a healthy Baltic Sea,” said the Executive Secretary of HELCOM, Rüdiger Strempel, in his opening plenary address, adding that the update of the plan is already well set to uphold this legacy. The BSAP is due to be updated later this year at the next HELCOM Ministerial Meeting.

Besides the BSAP, several round table sessions were dedicated to other pressing issues such as hazardous substances, and specifically on the modernizing of the HELCOM framework dealing with the issue. HELCOM is currently reviewing its processes on hazardous substances to allow a faster and more efficient response to emerging challenges caused, for instance, by the introduction of new chemicals used in industry and consumer products. The new strategic direction will also enable a better understanding of the full diversity of sources and pathways of contaminants to the Baltic Sea.

During the forum, other key discussions touched on river basin management and marine spatial planning, as well as on the implementation of projects conducted by way of cross-border cooperation.

Close attention was also paid to the adaptation to climate change, notably in connection with the implementation of the Agenda 2030 in 80 cities of the Union of the Baltic Cities (UBC) as well as in light of current trends in Russia.

“Traditionally, the Forum brings together scientists, representatives of government and business, public organizations and everyone who understands their responsibility to future generations for preservation of the unique ecosystem of the Baltic Sea,” said Ivan Serebritsky, the Deputy Head of the Committee for Nature Use, Environmental Protection and Ecological Safety of Saint Petersburg during his opening remarks. 

Held in a hybrid online and in-person format, the “Baltic Sea Day” Forum was coordinated by the Government of Saint Petersburg, Russia and the State Company “Mineral”, with support from HELCOM, the Ministry of Natural Resources and Environment of the Russian Federation, and the Committee for Nature Use, Environmental Protection and Ecological Safety of Saint Petersburg.

“There’s a long tradition of HELCOM involvement in the Baltic Sea Day Forum that has been held annually since 2000 in Saint Petersburg,” said Strempel, adding that during its 20-year history, the forum has become a key platform for the environmental dialogue at the regional and global level.

In a bid to better understand the effects of certain hazardous substances on the Baltic Sea, HELCOM, in collaboration with Stockholm University’s Baltic Sea Centre, has compiled the latest science on selected chemical contaminants.

The results were published in four reports, namely on dioxins and PCBs, brominated flame retardants, PFOS and PFAS, and diclofenac.

“We must identify the major sources of the hazardous substances and understand how they move in the ecosystems to be able to do something about the problem,” said Emma Undeman, a researcher at Stockholm University and lead author of the reports. 

The reports give insights into the sources and pathways to the sea of the addressed substances, as well as on how their concentrations have changed in the Baltic Sea over time.

Dioxins and PCBs, mainly by-products from industrial processes, primarily stem from atmospheric emissions, further persisting in the environment and accumulating in the food chain. This is a particular cause for concern since these substances are known for their adverse effects on the nervous, immune and endocrine systems of living organisms.

The levels of brominated flame retardants (PBDE) – which are now either banned or regulated but were heavily used in the past as additives to prevent ignition and delay spread of fire such as in furniture and curtains – seem to be declining, but trends show that it could take up to 40 years for these contaminants to reach safe levels in the Baltic Sea.

With regard to PFOS and PFAS, used for instance in metal coatings such as Teflon or in firefighting foams, the main pathways are discharges from wastewater treatment plants, and runoff from contaminated sites via groundwater and drainage ditches. Research on PFOS in Baltic Sea biota further indicates that transport to the sea has dropped but that concentrations have not yet declined, pointing towards a high persistence in the marine environment.

Diclofenac, a widely used painkiller that is water soluble, mainly enters the sea through wastewater treatment plants which have a low removal rate of the drug. Despite good absorption by the human body when ingested, diclofenac is overused, leading to significant excretions reaching sewer systems. Some of the diclofenac in wastewater may also originate from dermal application which has a low absorption rate by the body. 

The four reports support the update of the HELCOM Baltic Sea Action Plan (BSAP), HELCOM’s strategic programme of actions for restoring good ecological status of the Baltic marine environment. The BSAP is due to be updated in 2021.

Information from the reports will notably serve to evaluate the efficiency of currently implemented measures under the present BSAP, and for suggesting additional measures needed to improve the Baltic Sea’s state in regard to the reduction of concentrations of hazardous substances.

With the recent publication of the Review of existing policies and research related to microplastics under the FanpLESStic-sea project, policy-makers and researches in the Baltic Sea region dealing with microplastics now have a common baseline to support their work.  

“I was surprised by the large amount of existing research and projects in the Baltic Sea,” said Aaron Vuola, the HELCOM project coordinator in FanpLESStic-sea who led the publication, adding that it shows how pressing the issue of microplastics is in the region.

The review, for which a summary for policy makers is also available, establishes a comprehensive baseline on the existing policies related to microplastics on global, Baltic Sea, EU, and national levels. The report also showcases some of the existing research on microplastics at these various levels.

“This review confirms the need for harmonized monitoring methods if we want to be able to compare studies between regions and different matrices, or establish baselines for current microplastic levels,” said Vuola.

According to the report, the lack of commonly agreed methodologies for monitoring, sampling and analyses of microplastics is a major concern and calls for urgent need for harmonized, cost-efficient, and sufficiently robust monitoring methodologies for microplastics.

Currently, microplastics are not directly addressed through any global instrument even though several existing instruments cover some aspects related to marine litter and hence microplastics. However, the European Union is working towards restricting the use of intentionally added microplastic particles to consumer or professional use products.

On the Baltic Sea level, actions on microplastics are contained in the HELCOM Action Plan on Marine Litter.

Also highlighted by the report are the impacts of microplastics on humans through food chain or other means, still largely unknown and calling for more research.

“There is already lot of evidence of the negative impacts of microplastics to support the need for global, EU and national level regulation, but we also have to reduce the plastic use in general and address the problematic products in earlier phase of their life-cycle before they become marine litter and microplastics,” said Vuola.

In addition to providing an overview of the regulatory framework and useful information on topics such as sources and types of microplastics, the report can be used as a database for large amount of concluded research on various topics around the issue of microplastics.

FanpLESStic-sea, an EU-funded Interreg project, works towards preventing and decreasing the pollution of microplastics in water in the Baltic Sea. In the project, HELCOM leads the work package on reviewing existing research on microplastic in the aquatic environment.
