Exposure of Bromus hordeaceus to fossil- and plant-based micro- and nanoplastics: Impacts and plant-plastic interactions vary depending on polymer type and growth phase.

Plastic pollution, especially pollution by micro- and nanoplastics, is now considered a potential threat to all ecosystems, including terrestrial ecosystems such as grassland habitats. This study investigated the impacts of micro- and nano-sized plastics on Bromus hordeaceus, a common grass species in European grasslands. The micro and nanoparticles were fossil-based polyethylene (PE) or plant-based polybutylene adipate terephthalate (PBAT), and these two plastics were used at two different concentrations.

Microplastics and cellulosic microparticles in North Atlantic deep waters and in the cold-water coral Lophelia pertusa.

This study explores microplastic and cellulosic microparticle occurrences in the NE Atlantic, focusing on the Porcupine Bank Canyon and Porcupine Seabight. Water samples from depths ranging between 605 and 2126 m and Lophelia pertusa coral samples from 950 m depth were analysed. Microparticles were detected in deep-water habitats, with concentrations varying from 2.

Fate of petroleum-based and plant-based teabags exposed to environmental soil conditions for one year.

Petroleum-based plastics are materials which have provided important industrial benefits from being lightweight and having low production costs. However, plastic pollution is pervasive and ubiquitous on all environments. This has led some industries to rapidly introduce the so called 'bioplastics' into the market by switching the conventional ones for new plant-based alternatives with similar properties.

Adsorption, uptake and toxicity of micro- and nanoplastics: Effects on terrestrial plants and aquatic macrophytes.

Plastic pollution is a new, pressing, environmental topic. Microplastics are considered contaminants of emerging concern and, consequently, microplastic research has grown exponentially in the last decade. Here, current knowledge regarding the impacts of micro- and nanoplastics on terrestrial plants and aquatic macrophytes is discussed, with a special focus on adsorption, uptake and toxicological effects.

Beyond plastic microbeads - Short-term feeding of cellulose and polyester microfibers to the freshwater amphipod Gammarus duebeni.

Monitoring studies have revealed the presence of large numbers of natural as well as anthropogenic microfibers, plastic and non-plastic, in environmental samples. However, the interaction of organisms with microfibers is largely understudied. This is the first ecotoxicological study that compares short-term feeding of anthropogenic plastic and non-plastic microfibers on a consumer (leaf-shredding detritivores) species.

Rapid fragmentation of microplastics by the freshwater amphipod Gammarus duebeni (Lillj.).

Microplastics have become ubiquitous in all environments. Yet, their environmental fate is still largely unknown. Plastic fragmentation is a key component of plastic degradation, which is mostly caused by abiotic processes over prolonged time scales.

Polyethylene microplastics adhere to Lemna minor (L.), yet have no effects on plant growth or feeding by Gammarus duebeni (Lillj.).

Microplastics (1-1000 μm) are ubiquitous in the marine, freshwater and terrestrial environments. These microsized plastics are considered freshwater pollutants of emerging concern, although the impacts on organisms and ecosystems are not yet clear. In particular, effects of microplastics on freshwater aquatic plants and the fate of microplastics in the freshwater trophic chain remain largely unexplored.
