Beschreibung

The international conference provided an opportunity to learn and exchange knowledge on the topic of microplastics in soils and was aimed at scientists and decision-makers alike. The first day of the event focused on the state of the science, the second day on identifying technical options and political fields of action at the European and international level.

Research has shown that soils are a major sink for microplastics. A lot is known about microplastics in water, but there are still large gaps in research on plastics in soils, especially regarding the determination, distribution, transport and impacts of microplastic particles.

This two-day international conference featured the following topics:

Day 1: State of science
a. Pathways of entries and occurrence of plastic in soils
b. Behavior, fate, and impact of microplastics in soils
c. Analysis of microplastics in soils

Day 2: Need for action by policy makers
d. Technical and management solutions reducing plastic emissions into soils
e. Existing regulations affecting plastics in soils
f. Policy solutions at the European and international level
The conference will serve as an input for developing policy recommendations.

This hybrid event took place on 19 and 20 October, 2022 allowing for both in-person and online participation. The event was aimed at scientists and decision-makers.

Plastics are highly used materials that can be applied in many different ways. They successfully made their way into a lot of different industries and our daily lives, resulting in a steady increase in production and consumption over the last years. Nevertheless, they can become a problem for ecosystems when entering the environment. Plastics are degraded very slowly and can cause severe damage to living organisms and their habitats.

At this point, plastics are found in fresh and saltwater ecosystems like oceans, rivers and lakes as well as in soil. One of the main pathways of how plastics enter the environment is through inadequate waste and wastewater management, but there are many other sources like tyre abrasion, films from agriculture, or plastic particles from cosmetics or cleaning materials. In addition, littering causes more and more plastics to end up in the environment.

This paper from the German Environment Agency (UBA) shows – with regard to Germany - where we stand, what we need to do, what the research needs are, and which measures we can already introduce to tackle the problem.

Investigation of Sinks and Sources of Microplastics from a Typical Catchment Area to the Open Baltic Sea

This project determined sources and sinks of microplastic in the Warnow river basin, as well as relevant dissemination processes on its way to the open Baltic Sea. Separate models were linked so that the resulting model covers the entire river basin including estuary and coastal waters. The linked models served to identify hotspot areas of microplastic entry and to estimate the effects of microplastic reduction measures in parts of the river basin. By converting the models into a handson multitouch table, project participants made interactive, creative learning modules that were presented in the form of a traveling exhibition in communities around the German Baltic coast from Stralsund to Flensburg. Further, MicroCatch_Balt included the examination of anti-fouling paint and extreme weather events as sources and higher organisms as sinks. Based on this, MicroCatch_Balt covered the most important aspects of microplastic contamination of limnic to marine systems in northern Germany, thereby offering interest groups the expertise with which to develop future monitoring and strategies for reduction.

Main areas of work

Sampling in the Warnow river basin and estuary, extraction and identification of microplastics
Modelling of microplastic input into the Warnow system of diffuse and point sources
Development of two multi-media modules for a multi-touch table and organisation of a traveling exhibition

Microplastic Contamination in the Weser- Wadden Sea – National Park Model System: an Ecosystem-Wide Approach

In PLAWES, the modelling system of the German national park Weser-Wadden Sea was the first large European river basin that was investigated in detail regarding its microplastic pollution. PLAWES conducted a pioneering study of the microplastic contamination from the headwaters to the North Sea (northern Atlantic Ocean) that comprised an interdisciplinary and integrated ecosystem approach and accounted for various point sources (wastewater treatment plants, separation systems) and diffuse sources (drainage, atmosphere) of pollution. The results were integrated into a model for identifying primary transport mechanisms and accumulation zones. The research investigated the effects of microplastics on ecosystems in the Weser-Wadden Sea system by analysing the interaction of microplastic with pathogens in biofilm and aquatic invertebrates. Outcomes of this particularly ecologically relevant aspects were used to estimate the environmental risk of microplastics for the model system, and subsequently made it transferable to other systems. In addition, the results of the analysis became part of new teaching materials in order to provide a knowledge platform for teachers, students, and parents across Europe. PLAWES generated unique data about the effects of microplastics on a large European river basin and its environment. This is significant not only for policymakers and stakeholders but also as a fundament for science-based solutions to address the microplastics problem.

Short description
The aim of WP 1 was to investigate the entire Weser river system into coastal waters with regard to microplastic pollution. The final determination of the exact sampling points was carried out taking into account the real data required for RAUMISmGROWA- MePhos and "Tidal Model" (WP 3). The entire Weser including the Lower Weser and the Wadden Sea was investigated with regard to exposure to microplastic. Two campaigns were carried out at different seasons with different water conditions on the Weser.

Project partner
AWI

Short description
The aim of WP 2 was an exemplary consideration of the input paths for microplastics by investigation of important point sources such as wastewater treatment plants and separation water sewer systems as well as the diffuse input from drains and atmosphere. For this purpose, selected sampling points in the Weser river basin were characterised taking into account different landscape areas and land use types. The focus lay on quantifying the entry points of microplastics. Sampling was synchronised with the campaigns at the Weser.

Short description
The aim was a spatially resolved quantification of the microplastic emissions from diffuse and point sources and the identification of spatial load centres and accumulation zones within the river basin and estuary. The microplastic entries were modelled from different types of diffuse entry points and point sources. The work was based on the models mGROWA, MEPhos, RAUMIS, as well as a transport modelling considering the estuarine hydro- and sediment dynamics. Within the framework of the project, the model chain was improved in a targeted manner according to microplastic entry modelling in the inland and the further distribution of the microplastics in the lower reaches, estuary and apron.

WP 4 Interaction of microplastic with pathogens and biota

Project partner
AWI, UBT, UOld

Short description
In WP 4, the ecosystem effects of microplastic on the Weser-Wadden Sea model system were described on the basis of the two ecologically relevant aspects "Interaction with pathogens and antimicrobial resistance" and "Interaction with aquatic invertebrates".

Interaction with pathogens and antimicrobial resistance: Since biofilms are sites of increased genetic exchange and increased antimicrobial resistance occurs below wastewater treatment plants, plastics could not only contribute to the dispersion of pathogenic organisms, but also of resistance genes. The consequences of such a transfer were previously unknown. AWI therefore used molecular microbial source tracking techniques (DNA/RNA arrays for the detection of pathogenic bacteria, viruses, protozoa and virulence/resistance genes) to investigate plastic samples from the Weser region. Interaction with aquatic invertebrates: In order to generate exposure data, different mollusk species were applied in situ in the Weser, the tidal area and the Wadden Sea. Absorbed microplastic was examined in the digestive tract and in tissue samples and confirmed in parallel by pyrolysis-GC-MS and spectroscopic methods. Historical mussel samples (since 1986) from the Federal Environmental Specimen Bank (UBA) were examined using pyrolysis-GC-MS. The chronic toxicity of microplastic is characterised in laboratory experiments with mussels and worms. Different polymers were conditioned in situ and toxicologically characterised in chronic exposure experiments.

Short description
In addition to the ethical assessment skills of students, WP 5 incorporated existing individual environmental knowledge. Innovative teaching materials with a sound reference to everyday life were evaluated for a holistic understanding regarding the burden of plastics in the model system and disseminated via an Internet teaching/learning portal. Within the work package, UBT provided a handbook for teachers and "public relations workers".

Microplastics in Inland Waters – Investigation and Modeling of Entries and Whereabouts in the Danube Area as a Basis for Action Planning

Within the framework of this project, a first-ever accounting of macro-, meso- and microplastics released into the German part of the Danube river basin was achieved, with measuring stations at its main tributaries. Microplastic particles (particles < 5 mm) were examined by using various, complementary analytical methods. The focus lay on specifically small particles that are invisible to the naked eye with diameters less than 300 μm as there is currently a distinct lack of data about these particles. This project mapped the sources, sinks, transport processes and fragmentation of plastics in separate material flow models for micro- and macroplastics. Targeted, standardised sampling and supplementary laboratory experiments are clarifying the relevance of previously neglected input paths such as agricultural land or atmospheric deposition. Results were implemented into existing models, the models were validated and a plastic balance for the German Danube watershed was prepared. Through scenario analyses, it was possible to identify measures to reduce plastic pollution at the level of entire river basins.

Main areas of work

Entry balancing of macro-, meso- and particularly microplastic in the German Danube river basin through uniform sampling campaigns, modelling and supplementary laboratory tests
Balancing of previously unconsidered sources and sinks, such as the input of plastic by agriculture, atmospheric deposition of microplastic and degradation processes of plastics in the environment
Derivation of minimisation strategies

Short description
In this work package, the samples from WP 3 and WP 4 were analysed using three complementary methods. Starting from a high sample volume, these were pre-selected in advance by BfG using an effective screening procedure (low sample preparation effort, sample analysis using pyrolysis gas chromatography coupled with mass spectrometry). Samples with contents above a threshold value to be defined were subjected to a much more complex and precise analysis using Raman (TZW) and IR spectroscopy (LfU). These processes provided detailed information on particle properties (concentration, size, polymer type, and shape).

Short description
The first step in mass balancing of the selective and diffuse input of microplastics requires a characterisation of all potential sources. The aim of WP 3 was therefore to investigate and quantify entries from points and areas in limnic systems. The results were incorporated in WP 5. The focus was on atmospheric deposition, linear inputs in connection with littering, wastewater treatment plants, landfill leachates, and the weathering of plastics.

Short description
In addition to sinks such as hydroelectric power plants, this WP looked at transport and relocation processes of microplastics and possible intermediate reservoirs for microplastics such as soils or water sections with low flow. In addition, degradation and comminution processes of plastics were investigated in laboratory experiments. Sinks or reservoirs for microplastics were identified by coordinated sampling in the water body and mass balancing of a water body section. The results of WP 4 were incorporated into the models of WP 5.
