Particles from everyday wall paints can harm living organisms –novel membrane shows high filtering effects

Dispersion paints are mostly used in households for painting walls and ceilings. An interdisciplinary research team from the University of Bayreuth has now analysed the chemical composition of two typical dispersion paints and discovered a large number of solid particles in them which are only a few micro- or nanometers in size. Studies on biological test systems showed that these particles can harm living organisms. Using a novel membrane developed at the University of Bayreuth, these particles can be filtered out of water before they enter the environment.

New study from Bayreuth: Fertilisers from composting plants contain large quantities of biodegradable plastics

Composting plants process biowaste into finished compost, which ends up as fertiliser in the soils of fields and gardens. A study by the University of Bayreuth shows that finished compost from composting plants in Germany contains a large number of biodegradable plastic particles. Applicable legal and certification standards are not violated by the sizes and quantities of the particles detected. However, the data published in "Scientific Reports" call into question the contribution of these standards to effective environmental protection. They draw into question whether biodegradable plastics are suitable for replacing conventional plastics in environmentally and nutritionally sensitive areas.


New study examines microplastic pollution in Rhine floodplain near Cologne

Microplastic particles can be deposited in river floodplains and penetrate into deeper areas of the soil. The number of particles identified depends in particular on surface plant cover, the frequency of flooding, and soil properties. Researchers from the Universities of Bayreuth and Cologne determined this during investigations in the Rhine floodplain of Langel-Merkenich north of Cologne. The study, published in the journal "Science of the Total Environment", is the result of interdisciplinary cooperation in the DFG Collaborative Research Centre 1357 "Microplastics" at the University of Bayreuth.

Nanoplastic particles love company: researchers in Bayreuth analyze polyethylene degradation in the environment

Polyethylene, a plastic that is both cheap and easy to process, accounts for nearly one-third of the world’s plastic waste. An interdisciplinary team from the University of Bayreuth has investigated the progressive degradation of polyethylene in the environment for the first time. Although the degradation process leads to fragmentation into ever smaller particles, isolated nanoplastic particles are rarely found in the environment. The reason is that such decay products do not like to remain on their own, but rather attach rapidly to larger colloidal systems that occur naturally in the environment. The researchers have now presented their findings in the journal Science of the Total Environment

Prof. Kress and his PhD Student Simon Wieland are discussing microparticle properties.

Learning from dust: microplastic researchers compare health risks of microparticles

What are the consequenes of inhaled microparticles?
In order to better understand them, researchers from the CRC 1357 microplastic at the University of Bayreuth have conducted an interdisciplinary study to find out how the health risks of particles such as soot, grinding dust or asbestos are related to their physical properties. By comparing them with the properties of microplastic particles, more precise statements can be made about their potentially hazardous effects on health. 

Expert opinion on the plastic bag ban in Germany

The plastic bag ban will come into force on 1 January 2022. Then, with few exceptions, plastic bags may no longer be sold at supermarket checkouts. Prof. Dr. Christian Laforsch, spokesman of the Collaborative Research Centre (SFB) Microplastics at the University of Bayreuth, sees the plastic bag ban primarily as a symbolic step and emphasises the need for a true circular economy, the avoidance of plastic waste and a higher appreciation of plastics.
Nevertheless, he welcomes the current measures. In addition to the plastic bag ban, these are the ban on disposable articles and an extension of the mandatory deposit, which will be extended to all disposable plastic bottles and beverage cans in 2022..

Supposedly similar microplastic particles show different levels of toxicity

More and more studies worldwide are looking into the effects of microplastics, especially with regard to the environment and health. They often use spherical polystyrene microparticles and have arrived at partly contradictory results. An interdisciplinary research team at the University of Bayreuth has discovered a reason for this. Commercially available, supposedly identical polystyrene particles differ significantly, depending on the manufacturer, in terms of their structure and properties. Therefore, their interactions with living cells have different consequences for cell metabolism. The scientists have presented their study in the Journal of Hazardous Materials.

The third place of the Sustainability Award of the University of Bayreuth goes to Sarah Spreng and her bachelor thesis

Sarah Spreng is the third-place winner of the University of Bayreuth's Sustainability Award. Her final thesis "Investigation of adhesion between microplastic particles and cells using microfluidics" within the Bayreuth Collaborative Research Centre "Microplastics - SFB 1357" looks at the increasing contamination of the environment with microplastics. In a large number of experiments, Spreng examined microplastic particles and their adhesion behaviour to different cells. The work contributes to understanding what happens to microplastic particles in the body and what potential health risks result from them.
The work was supervised by PhD student Simon Wieland and Prof. Dr. Holger Kress (Experimental Physics VI - Biological Physics).

Rainfall causes microplastic transport into the atmosphere

Oceans, lakes and rivers often contain a large number of microplastic particles on their surface. Impacting raindrops cause many droplets with an almost equally high concentration of microplastics to be thrown up into the air. When they evaporate in the air, the particles enter the atmosphere. Researchers from the University of Bayreuth describe these processes in a new study published in "Microplastics and Nanoplastics". In an initial estimate, which is still fraught with uncertainty in several respects, they come to the conclusion that, worldwide, up to 100 trillion microplastic particles could enter the atmosphere every year as a result of rainfall.

Pathogenic fungi colonise microplastics in soils

Representatives of numerous pathogenic fungal species are finding new habitat on microplastic particles in the soil and could thus be one of the possible causes of an increase in fungal infections. Researchers from Bayreuth, Hannover and Munich demonstrated this in a new study. Using high-throughput methods, the scientists analysed fungal communities from soil samples taken from sites near human settlements in western Kenya. The findings of this research have been published in the journal Scientific Report.

United against microplastics in food: New joint project strengthens cooperation between research and industry

High-tech methods for detecting microplastics in food and suitable prevention measures are the focus of the joint German-Austrian Cornet project "MicroplasticATfood", which kicked off on 1 July 2021. With its expertise in microplastic research, the University of Bayreuth is involved in interdisciplinary case studies dealing with packaging, filling lines, beverages, surfaces of solid food, and soluble foods. On the German side, the project will be funded by the Federal Ministry for Economic Affairs and Energy until 2023 to the tune of € 542,000, of which about € 275,000 have been allocated to the University of Bayreuth.

New long-term study by the University of Bayreuth shows the rapid formation of micro- and nanoplastics in the environment

Most microplastic particles in the environment originate from larger pieces of plastic. In a long-term study, an interdisciplinary research team at the University of Bayreuth has simulated how quickly plastic breaks down into fragments under natural influences. High-tech laboratory tests on polystyrene show two phases of abiotic degradation. To begin with, the stability of the plastic is weakened by photo-oxidation. Then cracks form and more and more and smaller fragments are released into the environment. The study, published in the journal "Environmental Science & Technology", allows conclusions to be drawn about other plastics that are common in the environment.

University of Bayreuth partner in new EU project on effects of micro- and nanoplastics in agriculture

The University of Bayreuth is a partner in the new European "PAPILLONS" consortium for micro- and nanoplastics research in agriculture. 20 universities and research institutions from 12 countries will jointly investigate the sustainability of plastic use in European agriculture. The focus is on the input of plastic particles and chemical additives into arable land, and their possible ecological and socio-economic effects. The European Union is funding the project until 2025 to the tune of € 7.2 million in total, of which € 600,000 euros have been allocated to the University of Bayreuth. At a virtual kick-off meeting on 14 and 15 June 2021, the research partners agreed on what the next steps in their work would be.

This will not only bring the latest research results from experts in the field of research into the classroom. There will also be aids for distance teaching.

Bayreuth study: the most consumed species of mussels contain microplastics all around the world 

"If you eat mussels, you eat microplastics." This was already known to a limited extent about mussels from individual ocean regions. A new study by the University of Bayreuth, led by Prof. Dr. Christian Laforsch, reveals that this claim holds true globally. The Bayreuth team investigated the microplastic load of four mussel species which are particularly often sold as food in supermarkets from twelve countries around the world. The scientists now present their research results in the journal "Environmental Pollution".

University of Bayreuth Study: Natural environmental conditions facilitate the uptake of microplastics into living cells 

The environment is polluted by microplastics worldwide. Tiny particles enter food chains, and thereby the digestive systems of animals and humans; moreover, they can be inhaled. Instead of being excreted, small microplastics can be incorporated into the body tissue. A research team at the University of Bayreuth has now discovered that microplastic particles find their way into living cells more easily if they were exposed to natural aquatic environments, i.e. fresh water and seawater. The researchers have presented their results in the journal "Science Advances".

Sustainable plastics: University of Bayreuth researchers contribute to international White Paper

Researchers of the University of Bayreuth have taken a leading role in developing a White Paper on sustainable plastics, which four chemical associations from Germany, the UK, China, and Japan published today under the title "Science to enable sustainable plastics". The White Paper contains numerous recommendations for future research into the environmental impact of plastics, the development of new plastics, as well as recyclability and natural degradation.

Plastic waste disrupts communication: Bayreuth study shows risks for ecosystems

Plastic waste affects organisms living in water in a way that has received little attention so far: Messenger substances that are indispensable for communication under water accumulate on the surface of plastic particles and can thus no longer fulfil their ecological functions. Scientists at the University of Bayreuth show this in a new study using water fleas as an example. The animals form defence structures when messenger substances signal to them that they are threatened by predators. However, the defences are significantly weaker as soon as there is plastic waste in the water. The scientists present their findings in Scientific Reports.
