“…Other potential sources of local MP contamination of soils and groundwater are the addition of synthetic polymer-based (usually PP) fibres, as strength enhancement (reinforcement) for ground improvement, and synthetic polymers, including tyre derived aggregates (TDAs) used, for instance, as partial replacements for natural soils and aggregates in the construction of road embankments and pavement subgrades and as lightweight backfill to bridge abutments and retaining walls. As well as the MP particles derived from weathering and physical breakdown of the TDA additive in situ, there is the potential toxicity of leachates containing heavy metals and other chemicals common in TDA materials, as additional sources of contamination to the terrestrial environment (Vaverková and O'Kelly, 2022). For instance, Tallec et al (2022) emphasised that the use of rubber-based products (e.g.…”

Plastic pollution in the terrestrial environment is emerging as another significant manmade threat to ecosystem function and health. Plastic contamination can range from the macro-to-nano scale, and environmental impacts are evident at each level. Although significant knowledge gaps remain regarding the interactions between the natural environment and nano- and micro-plastics (NMPs), there is an increasing body of evidence concerning detrimental effects on a wide range of taxa. The surface properties of NMPs lead to the adsorption of heavy metals, endocrine-disrupting chemicals, antibiotics and other persistent organic pollutants, which, therefore, can result in their co-migration in the terrestrial environment. Although airborne and dietary transmission routes of NMPs have been observed, their effects to human health are still not fully understood, which is of concern to the scientific community. This state-of-the-art review paper firstly examines available evidence for, and knowledge of, various sources of NMP contamination to the terrestrial environment. Attention then focuses on (i) the biological processes from source to soils and plants, (ii) potential impacts of NMPs on soil and subsurface ecosystems, (iii) trophic interactions and function, and (iv) implications for environmental and human health. The paper concludes by identifying knowledge gaps and presents recommendations on prioritised research needs.
