Zanieczyszczenie gleb mikroplastikami i jego skutki dla roślin

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.
