Review of the toxic effect of microplastics on terrestrial and aquatic plants
AI summary Read the abstract
This review summarizes research on how microplastics affect both terrestrial and aquatic plants, finding that their toxicity depends on the type, size, and surface chemistry of the plastic particles. Researchers found that seeds and root systems are particularly vulnerable to microplastic exposure, and that the harmful effects differ between land and water plants. The study also highlights that chemicals released from or adsorbed onto microplastics pose additional secondary risks to plant health.
As a new pollutant, microplastics (MPs) exhibited more and more significant influence on the organisms in the environment. Especially, the effects on the growth and development of plants by MPs attracted wide attentions in recent period. In the review article, we summarized the important influences of MPs on terrestrial and aquatic plants. The properties, including type, size and oxygen-containing group of MPs on their physical injures toward plants were critically reviewed, which were significantly correlated to the toxicity to plants. The secondary risks of MPs including the additives and MP-derived organic products and the adsorbed environmental pollutants to plants were clearly revealed. The hydrophobic organic pollutants released from MPs showed significant chemical effects on the plants. We also outlined the effects of MPs to the various regions (e.g. the seed and rhizome) of plants and compared the toxic difference of MPs on terrestrial and aquatic plants. Generally, the seed and rhizome of plants were susceptible to MPs, and the effects of MPs on terrestrial and aquatic plants were different. The review paper improves the understanding of potential toxicity of MP themselves and the released and adsorbed chemicals to plants in the environment.

Microplastic/nanoplastic toxicity in plants: an imminent concern
AI summary Read the abstract
This review examines the growing body of research on how microplastics and nanoplastics affect terrestrial plants, from root uptake to changes in growth and gene expression. Researchers found that these particles can alter plant physiology and biochemistry at varying degrees depending on particle size and concentration. The study calls for more research on how plastic contamination in soil may ultimately affect food crop quality and human health through the food chain.
Impacts of microplastics on terrestrial plants: A critical review
AI summary Read the abstract
This review examines how microplastics affect land-based plants, finding that they can alter soil structure, disrupt beneficial soil microbes, and reduce plant growth. Microplastics also carry toxic chemicals like plasticizers and heavy metals that can be taken up by plant roots and enter the food chain. The findings raise concerns about human health since contaminated crops could be a hidden source of microplastic and chemical exposure in our diets.
Perspectives and challenges of micro/nanoplastics‐induced toxicity with special reference to phytotoxicity
AI summary Read the abstract
This review examined the phytotoxic effects of micro- and nanoplastics on plant systems, noting that plastic concentrations in terrestrial environments are often higher than in aquatic ones. Researchers found that these particles can alter soil enzymatic systems, affect soil microorganisms and earthworms, and impact plant growth and physiology, though the study emphasized that research on terrestrial phytotoxicity is still limited compared to aquatic studies.
