“…Apparel also includes footwear, which is made with a greater amount of plastic and releases microplastics from shoe sole fragments. These microplastics from shoe fragments are 57-229 μm in size and have been found to directly affect plant growth and photosynthesis activity (Lee et al, 2022). This study also found that such fragments from shoe soles can impair soil and suggested using materials having less harmful environmental effects.…”

The footwear industry’s transition to a circular economy is a essential for sustainable development. The emerging recycled shoe production may lead to sustainable consumption in the footwear industry. Consumers are now more cognizant of the negative effects of their shopping choices. We studied the factors influencing consumers’ intentions of buying recycled shoes. We applied the theory of reasoned action (TRA) and the theory of planned behaviour (TPB). As this is an emerging trend, there is a dearth of sufficient literature regarding sustainable recycled shoe purchase behaviour. We aimed to fill this broad gap with this empirical research. We found that perceived environmental knowledge, subjective norms, sustainable label awareness, and shoe choice motives influenced attitude, and attitude, word of mouth, and environmental consciousness shaped purchase intentions. Sustainable label awareness, shoe surplus, and purchase intentions affected purchase behaviour. The study is beneficial for policymakers and managers of companies for making decisions related to footwear product positioning and targeting.

“…In the sole study investigating plastic pollution on mountain trails, food packaging, mountaineering equipment and clothing accounted for the majority of larger macroplastics (plastic particles >5 mm) that contained polyethylene, polystyrene, polypropylene, polyester and polyurethane (Parolini, De Felice et al 2021 ). A wide range of other polymer types were identified in the trail runoff, indicating that MP pollution from hiking and trail running may have a mix of biological, microbiological, chemical and physical effects on the soil environment (Ingraffia, Amato et al 2021 , Colzi, Renna et al 2022 , Lahive, Cross et al 2022 , Lee, Kim et al 2022 , Sun, Duan et al 2022 ). Further research is required to determine the implications of MPs on ecological processes and plant and animal species in conservation and protected areas, particularly polyurethane fragments and polyester and nylon fibres.…”

“…The density of the rubber outsole material (σ = 1.1 g cm −3 ) was determined based on the mass and volume of three samples (with the volume determined using the water displacement method (Flowers, Theopold et al 2019 )). Rubber MPs were used to assess MP mobility as shoe abrasion may be a significant contaminant in areas with high foot traffic (Forster, Tighe et al 2020 ) and leachates have been shown to have phytotoxic effects (Lee, Kim et al 2022 ). Coloured rubber MPs were selected for the study as they were easier to detect in an organo-mineral matrix than darker particles, and preliminary analysis indicated pink MPs were not already present on the trail surfaces of this study.…”

Hiking and trail running are a source of microplastic (MP) pollution on recreational trails in wilderness and conservation areas; however, the fate of MPs deposited on trails is poorly understood as MP mobility on such surfaces has not yet been examined. In this study, we simulated heavy rainfall (100 mm/h) on trail surfaces with existing MP pollution (in situ MPs) and spiked with 99 ± 2 rubber MPs (100–940 μm). Runoff was collected for 15 min and spiked and in situ MPs were quantified. Hydrological, erosional and microplastic responses were evaluated in relation to slope, bulk density, soil moisture and surface condition indicators, including amounts and types of surface cover and soil physical attributes. The MPs were largely immobile, with 85–100% of spiked MPs retained on trail surfaces. In situ MPs were detected in the trail runoff, with the majority being polyurethane, polypropylene and polyester. Microplastic movement was primarily influenced by hydrological effects, and analysis indicated the main explanatory variable was total runoff volume, followed by soil slaking. Trail sections with at least 15% herbaceous cover or a layer of loose alluvium had higher MP retention. Areas of resource accrual may be preferentially enriched, suggesting MPs from outdoor recreation may be concentrated on and adjacent to recreational trails. Microplastics deposited on trails may have long term implications for biodiversity and ecosystem functioning in wilderness and conservation areas, particularly around the trail corridor.

“…Since the weak bonding of the additives with the base polymer, the additives are susceptible to leaching, resulting in toxic effects on the plant (Hahladakis et al, 2018; Hermabessiere et al, 2017). Leachates from sole fragments were found to inhibit the photosynthesis of Vigna radiata (Lee et al, 2022). Lactic acid, a degradation product of polylactic acid (PLA), adversely affects the length of ryegrass branches (Boots et al, 2019).…”

“…Changes in the production of root exudation may influence the content of active state nutrients in the soil, thus indirectly affecting plant growth. In addition, the presence of root exudation may also lead to the leaching of other contaminants originally attached to NPs, thus altering their phytotoxicity (Lee et al, 2022). For example, the dissolution rates of MoO 3 , Cu (OH) 2 , Mn 3 O 4 and CeO 2 nanomaterials in soybean root exudation were 38%, 1.2%, 0.5% and <0.1%, respectively (Cervantes‐Avilés et al, 2021).…”

Nanoplastics (NPs) are accumulating in the soil environment at a rapid rate, which may cause serious consequences for ecosystems and human health. However, environmental behaviour and toxicity of NPs in the soil-plant system remain poorly understood. This review summarizes current studies on NP-plant interactions to unravel uptake mechanisms and phytotoxicity of NPs. NPs could be taken up by plant roots and transported upwards through the xylem to all organs of the plant, even to the edible parts such as the grain, thereby threatening human health.The interaction of NPs with plants affects plant transport of water and nutrients.Besides, it induces significant oxidative stress leading to inhibition of physiological and biochemical activities such as photosynthesis, and thus adversely affects plant growth and development. In addition, the co-transport of NPs with other soil pollutants may induce the combined toxic effects. This study also discussed the potential mechanism of NP-plant interactions based on previous experience with engineered nanomaterials. Finally, a comprehensive assessment of the key challenges in each area was presented, and future perspectives are offered.
