“…Marine litter is a global environmental problem threatening marine biota and public health. Plastic, the major component of marine litter (up to 90%; Galgani et al, 2015;Morales-Caselles et al, 2021;Scotti et al, 2021), is of particular concern due to its longevity and a wide range of harmful effects on organisms including internal injuries after ingestion, physical entanglement, and growth alterations (Bergmann et al, 2015;Menicagli et al, 2019a,b;Bucci et al, 2020;Menicagli et al, 2020). Plastic can also expose organisms to toxic compounds, such as additives used to manufacture items, and persistent organic pollutants adsorbed from the environment (Oehlmann et al, 2009;Rochman et al, 2013Rochman et al, , 2014Bejgarn et al, 2015;Balestri et al, 2019;Menicagli et al, 2019a).…”

“…Studies focusing on wild species are still scarce [23,24]. Field experiment investigating plastic (bag macroparticle) deposition on dune systems indicated morphological anomalies, reduced survival and colonization success of dune plants (e.g., Glaucium flavum Crantz, Sporobolus pumilus (Roth) P.M. Peterson & Saarela and Thinopyrum junceum (L.) Á. Löve), especially due to non-biodegradable plastics in combination to other environmental factors [25,26]. In controlled conditions, Lozano and Rillig [27] investigated the effects of microplastic fibers in plant communities showing that shoot and root mass can increase with microfiber addition, an effect likely related to a reduced soil bulk density and an improved aeration, allowing a better penetration of roots in the soil.…”

Toxic Impact of Soil Microplastics (PVC) on Two Weeds: Changes in Growth, Phenology and Photosynthesis Efficiency

Experimental evidence on the bio-ecological effects of microplastics on terrestrial plants is still lacking. In this study, we hypothesized that soil polluted with polyvinyl chloride (PVC) microparticles can negatively influence plant traits, photosynthetic efficiency and phenology of two weeds but with different strength in relation to the species’ life traits. Therefore, we conducted an experiment in a common garden growing the wild species Senecio inaequidens and Centaurea cyanus for about 60 days. The possible toxic effects of soil microplastics (1% of PVC in 100 g of soil medium) were investigated, coupling an analyses on plant traits with an evaluation of the microplastic-induced changes in terms of phenology and photosynthetic efficiency. Overall, results showed that plants in control pots were higher and larger than those in treated ones (C. cyanus plant width: p < 0.05; S. inaequidens—plant height: p < 0.05; plant width: p < 0.05). Moreover, for C. cyanus, photosynthetic efficiency (index Fv/Fm) was significantly lower in the treatment than that in control (p < 0.05). About phenology, the second leaf of S. inaequidens emerged earlier in control than that in treatments (day 12.2 ± 0.25 and 14.3 ± 0.3, respectively; p < 0.001). The obtained results highlight that PVC microparticles may have had negative effects on soil–plant system reducing the performance of plants. Since, up to now, research on the interaction between soil microplastics and terrestrial plants has mainly focused on agricultural plants, this work fills a gap of knowledge regarding wild species (weeds), highlighting the possible future impact of microplastics on biodiversity.

“…In addition, concerns also increase about marine plastic litters [72,73] . The exposure of plastic leachates on coastal dune plants was reported that plastic products (plastic bag, PE) could alter the seed growth and germination [74,75] . Additive leachates and plastic microparticles released from plastic products were detected to significantly influence the survival and activities of some marine organisms, including embryonic development of D-veliger larvae, coelomocyte phagocytic activity of lugworm Arenicola marina [54,76] .…”

The explosive growth of plastic consumption contaminates the natural environment seriously and microplastic debris with toxic additives threatens marine organisms and human health. Along with large amounts of plastic use, improper management of plastic wastes and pose bigger pressure to ecological environment. More than 90% of plastic discards are landfilled and combusted which could cause secondary contamination, while small parts are recycled which is time-consuming and costly. To date, scientists already have detected influence of plastic pollution in marine and terrestrial ecosystems. The uptake of plastic debris by marine organisms and toxicity impact on lifespan shortening are investigated. More researchers also explored the direct microplastic leaches from cosmetics, teabags, mineral water bottles, infant bottles and daily necessities. With increasing demands for plastic food packaging due to COVID-19 personal protection, the direct contamination released from plastic food containers with cooked food and hot beverages remains equivocal and becomes extra important. Plastic polymers, derived from petro and fuel chemicals, are ultra-resistant, easy-processing, low-costing, thermalstable and with great mechanical properties. Although plastic polymers and toxic additives are malignant, plastic inevitably promotes development of society. Scientists researched the biodegradation process of individual types of plastic through bacterium and cells which are expensive and complicated. On the other hand, discovering alternatives of plastic is compulsory that bioinspired and biological materials are significant because of biocompatibility and environmental protection.Bee pollen granules attract attention due to durable shell structure. Sporopollenin exine capsules (SECs), are extracted from bee pollen and resistant with anti-oxidation, ultraviolet resistance. SECs are widely applied as drug delivery vehicles including orally therapeutic medicine and anti-cancer drug carriers. Degradation of SECs in gastrointestinal tract fluids and human plasma are analyzed that proves enzymedependent and chemical/enzyme-dependent degradation with happens of SECs. Elastic Abstract pollen microgel particles are found to fabricate pollen papers with high surface contact areas. Pollen papers are elastic, flexible, easy processed that can be considered as alternatives of flexible plastic. However, the chemical-degradation without enzyme remains unknown.Herein, a significant amount of microplastics in the nanoscale range are demonstrated to be generated from the plastic packages that contact with high temperatures associated with cooked food or hot beverages. The quantities, diameters and morphologies of micro/nano plastic particles are refined and observed. In-vitro experiments are conducted and prove procedures of murine macrophages to inject different types of micro/nano plastics. The inhibited activity of lysosome presents the plastic effects to mammal organisms after long-term exposure. Human intake large quantities of plastic debris a...
