In the era of plastic pollution, plants have been discarded as a system that is not affected by micro and nanoplastics, but contrary to beliefs that plants cannot absorb plastic particles, recent research proved otherwise. The presented review gives insight into known aspects of plants' interplay with plastics and how plants' ability to absorb plastic particles can be utilized to remove plastics from water and soil systems. Microplastics usually cannot be absorbed by plant root systems due to their size, but some reports indicate they might enter plant tissues through stomata. On the other hand, nanoparticles can enter plant root systems, and reports of their transport via xylem to upper plant parts have been recorded. Bioaccumulation of nanoplastics in upper plant parts is still not confirmed. The prospects of using biosystems for the remediation of soils contaminated with plastics are still unknown. However, algae could be used to degrade plastic particles in water systems through enzyme facilitated degradation processes. Considering the amount of plastic pollution, especially in the oceans, further research is necessary on the utilization of algae in plastic degradation. Special attention should be given to the research concerning utilization of algae with restricted algal growth, ensuring that a different problem is not induced, "sea blooming", during the degradation of plastics.

Micro- and nanoplastics (MNPs) are emerging contaminants increasingly recognized for their environmental and health implications. While surface water systems have been extensively studied, the presence, behavior, and impacts of MNPs in groundwater remain underexplored, despite its critical role as water source worldwide. The findings in this review highlight that agricultural activities, particularly plastic mulches, pesticides containers, fertilizer bags, greenhouses, are major sources of MNP.

Polyethylene terephthalate (PET) glycolysis presents an effective solution to address plastic pollution while promoting the utilization of renewable resources. It is highly important to gain in-depth insights into the identification of the well-defined active sites and the structure-activity relationships in PET glycolysis. Herein, PW@UiO-67 with different exposed crystal facets, i.

Plastic pollution in marine environments poses ecological risks, in part because plastic debris can release hazardous substances, such as metal-based additives. While microplastics have received considerable attention as vectors of contaminants, less is known about larger macroplastics and their role in the spatial and temporal redistribution of substances. In this study, pristine, store-bought plastic items and macroplastics recovered from the North Pacific Subtropical Gyre (NPSG) were analysed using Fourier-Transform Infrared Spectroscopy (FTIR) to identify polymer types, and bulk acid digestion followed by Inductively Coupled Plasma Mass Spectrometry (ICP-MS) for total metal quantification.

The global accumulation of plastic waste, exceeding 360 million tonnes annually, represents a critical environmental challenge due to their widespread use and extreme recalcitrance in natural environments. Furthermore, the end-of-life processing of bioplastics, which are often marketed as eco-friendly, remains problematic, with biodegradation often requiring industrial conditions. Enzyme-based depolymerization of polyesters, such as polyethylene terephthalate (PET) and bioplastics (e.

Plastics, particularly polystyrene (PS), are extensively used worldwide, especially in disposable packaging, which contributes to environmental pollution by generating microplastic particles. Herein, we investigated the pulmonary toxic effects of PS microplastics, focusing on airway inflammation and immune response. PS microplastic (50 nm to 1 μm) exposure was more likely to cause a severe pulmonary inflammatory response, particularly with smaller particle sizes.
