Zanieczyszczenie gleb mikroplastikami i jego skutki dla roślin
AI summary Read the abstract
This review summarizes how micro- and nanoplastics are absorbed by plants and affect their growth, finding that smaller particles penetrate more deeply into plant tissues and cause oxidative stress, growth disruption, and structural cell damage with implications for food safety.
Micro- and nanoplastics (MNP) are ubiquitous environmental pollutants that can be absorbed by plants, affecting their growth and functioning. Research indicates that the size, surface charge, and physicochemical properties of MNP play a key role in the uptake and transport of these particles within plants. Most polystyrene nanoparticles accumulate in the roots, with limited transport to the above-ground parts. Smaller particles have a greater ability to penetrate plant tissues, potentially allowing them to move through the xylem. The toxicity of MNP stems from inducing oxidative stress, growth disturbances, and structural cell damage, which can have serious consequences for plant health and food safety. Moreover, interactions between MNP and heavy metals, such as arsenic, can exacerbate negative effects on plants. In view of the above, it is essential to undertake further research on the impact of MNP on plants, particularly regarding their penetration into the food chain.

Micro- and nanoplastics in terrestrial plants: uptake, accumulation, and impacts on growth and physiology
AI summary Read the abstract
Tiny plastic particles from broken-down waste are building up in soil and getting absorbed by plants through their roots and leaves, according to this review of existing research. Once inside, these particles can stunt seed sprouting, weaken root growth, and interfere with photosynthesis (how plants make energy from sunlight), which matters because these are the same crops we eat. Since the plastic can travel from soil into plant tissue, this raises questions about how much may be passing into our food supply and, ultimately, into us.
Micro (nano) plastic pollution: The ecological influence on soil-plant system and human health.
AI summary Read the abstract
This review examines how micro- and nanoplastics affect soil health, plant growth, and food quality, finding that these particles accumulate in plant root systems and can reduce crop yields and alter nutritional content. Since contaminated soil and water are increasingly delivering microplastics to food crops, these findings are directly relevant to agricultural food safety.
