Nano- and microplastics commonly cause adverse impacts on plants at environmentally relevant levels: A systematic review
Systematic review of 78 studies found that nano- and microplastics commonly cause adverse effects on plants even at environmentally relevant concentrations, with germination and root growth more strongly affected than shoot growth during early development. Chlorophyll levels were consistently reduced while stress indicators (ROS) and antioxidant enzymes were consistently upregulated across species.
Impacts of Micro(nano)plastics on Terrestrial Plants: Germination, Growth, and Litter
This review examines how micro and nanoplastics affect every stage of a plant's life cycle, from seed germination to growth to decomposition of dead plant material. The tiny plastic particles can physically block nutrient and water channels in plants, disrupt photosynthesis, and alter gene expression, with smaller nanoplastics generally causing more harm. These effects on plants are relevant to human health because they could reduce crop yields and allow microplastics to enter the food supply through contaminated produce.
Recent advances on microplastics/nanoplastics interaction with plant species: A concise review
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.
Effects of Microplastics on Germination and Seedlings Growth of Wheat (Triticum aestivum L.)
Researchers tested the effects of different microplastics on wheat seed germination and seedling growth and found that all treatments reduced plant development compared to controls. Polythene-containing microplastic treatments had the most negative impact, with significant reductions in both shoot and root length across wheat varieties.
Investigating the Impact of Microplastics Type of Polyethylene, Polypropylene, and Polystyrene on Seed Germination and Early Growth of Rice Plants
Researchers investigated how three common types of microplastics, polyethylene, polypropylene, and polystyrene, affect rice seed germination and early seedling growth. They found that microplastic exposure altered root development and shoot growth, with the effects varying by polymer type. The study raises concerns about how microplastic-contaminated agricultural soils could affect staple crop establishment and food production.
Effects of Different Microplastics on Wheat’s (Triticum aestivum L.) Growth Characteristics and Rhizosphere Soil Environment
Researchers exposed wheat plants to multiple types of microplastics — including polyethylene, polypropylene, and polystyrene — at different concentrations to compare their effects on plant growth and physiological parameters. Different polymer types caused varying degrees of growth inhibition and oxidative stress.
Effects of Microplastics on Higher Plants: A Review
This review examines how microplastics affect higher plants, covering impacts on seed germination, root growth, photosynthesis, and nutrient uptake, while highlighting the role of plastic type, size, and concentration in determining phytotoxicity.
Ecotoxicological effects of plastics on plants, soil fauna and microorganisms: A meta-analysis
Meta-analysis of 2,936 observations from 140 studies found that plastics caused substantial detrimental effects to plants and soil fauna, but had less impact on microbial diversity. Larger plastics (>1 um) impaired plant growth and germination while nanoplastics primarily increased oxidative stress, and soil fauna reproduction and survival were more adversely affected by smaller particles.
Lolium multiflorum germination and growth affected by virgin, naturally, and artificially aged high-density polyethylene microplastic and leachates
Researchers found that virgin, naturally aged, and artificially aged high-density polyethylene microplastics and their leachates negatively affected Lolium multiflorum germination and growth, with aged microplastics and their chemical leachates showing greater phytotoxicity than virgin particles.
Plant species-specific impact of polyethylene microspheres on seedling growth and the metabolome
Researchers modeled the lifecycle of plastic packaging and estimated the generation of secondary microplastics from different disposal pathways including landfill, incineration, and recycling. Results indicate that recycling significantly reduces microplastic generation but does not eliminate it entirely.
Effects of nano- & microplastics on terrestrial plants are ubiquitous and widespread: a systematic review
This systematic review finds that nano- and microplastics have widespread negative effects on plants, including reduced germination, stunted growth, and biochemical stress responses. Since plants form the base of our food supply, these findings suggest that microplastic contamination in agricultural soils could affect crop health and potentially the quality of food we eat.
The effects of microplastics on crop variation depend on polymer types and their interactions with soil nutrient availability and weed competition
Researchers investigated how different types of microplastics interact with soil nutrient availability and weed competition to affect crop growth. The study found that the effects of microplastics on plant performance depend on the polymer type and are modulated by fertilization levels and competition from weeds, suggesting that real-world agricultural impacts of microplastic pollution may be more complex than laboratory studies indicate.
