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 - Supplementary information
AI summary Read the abstract
This is a supplementary data file for a study on Bromus hordeaceus, a common European grassland grass, exposed to microplastics and nanoplastics made from fossil fuels or plant material. It provides detailed methods and measurements, including seed germination, root and shoot growth, plant dry weight, and nitrogen levels, supporting the main research article's findings.
This document serves as supplement to the article "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" investigating the impacts of micro-sized and nano-sized plastics on Bromus hordeaceus, a common grass species in European grasslands. The document provides information about the underlying methods and materials (plastic particles and their concentration) in combination with the results including (1) the germination success in seeds germinated in petri dishes in particle-spiked moist conditions, the (2) total radicle length and (3) sprout length in seeds germinated in petri dishes in particle-spiked moist conditions, (4) the shoot dry weight (g) – SDW_g- , (5) the root dry weight (g) – RDW_g- and (6) the plant dry weight (g) – PDW_g- of plants growing in soil spiked with plastic particles, (7) the average of delta (δ) ^15N from plants growing in soil spiked with plastic particles, and (8) the nitrogen accumulation (g of Nitrogen x g of plant material).

Exposure of Bromus Hordeaceus to Petroleum and Plant-Based Micro- and Nanoplastics: Impacts and Plant-Plastic Interactions Vary Depending on Polymer Type and Growth Phase
AI summary Read the abstract
Researchers exposed a common European grass species to petroleum-based polyethylene and plant-based PBAT micro- and nanoplastics, finding that while all plastic types stimulated early root growth in vitro, soil-grown plants showed growth suppression from microPBAT — and microscopy revealed for the first time that roots can physically penetrate and perforate plastic particles.
Effects of Microplastic Particles and Microplastic Leachate on the Germination and Growth of Lolium multiflorum
AI summary Read the abstract
Researchers tested whether polypropylene microplastic particles and the chemicals they leach affect Italian ryegrass germination and growth. Both physical microplastic particles and their leachate reduced germination rates and seedling growth, suggesting that both the particles themselves and their chemical additives can harm terrestrial plants.
Recent advances on microplastics/nanoplastics interaction with plant species: A concise review
AI summary Read the abstract
This review synthesizes research on how microplastics and nanoplastics interact with plants, finding that plastic particles in soil can interfere with root uptake, germination, and crop yields depending on the type and concentration of plastic present. The findings are particularly relevant to human health because food crops grown in microplastic-contaminated agricultural soils may absorb or accumulate plastic particles, creating a direct dietary exposure route.
