Urban areas play a key role in the production of microplastics (MPs) and their entry into water bodies. This article reviews literature on sources, transport, control MPs urban environments with aim clarifying mechanisms underlying these processes. Major MP sources include atmospheric deposition, micro-litter, tire road wear particles (TRWPs). deposited from atmosphere are mostly fibers may be particularly important catchments without traffic. Littering attrition textiles plastic products is another source. However, quantities originating this source hard to estimate. TRWPs significant arguably best quantified The mobilization poorly understood but it appears that dry unconsolidated sediments deposits most readily mobilized. Sequestration occurs green understood. Consequently, some authors consider green/pervious parts sinks. Field studies have shown appreciable removal stormwater quality facilities. Street cleaning snow also remove (particularly TRWPs), efficacy measures unknown. Among management facilities, biofiltration/retention units seem more effectively than facilities relying settling. knowledge remains incomplete. Finally, although 13 research papers reported concentrations stormwater, total number field samples examined was only 189. Moreover, results not necessarily comparable because they based relatively small numbers differ widely terms objectives, sites, analytical methods, size fractions, polymers, even terminology. area can thus considered "data-poor" offers great opportunities for further many areas.

Microplastic stress in plants: effects on plant growth and their remediations

Frontiers in Plant Science, Год журнала: 2023, Номер 14

Опубликована: Авг. 11, 2023

Microplastic (MP) pollution is becoming a global problem due to the resilience, long-term persistence, and robustness of MPs in different ecosystems. In terrestrial ecosystems, plants are exposed MP stress, thereby affecting overall plant growth development. This review article has critically analyzed effects stress plants. We found that stress-induced reduction physical accompanied by two complementary effects: (i) blockage pores seed coat or roots alter water nutrient uptake, (ii) induction drought increased soil cracking MPs. Nonetheless, physiological under four excessive production ROS, alteration leaf root ionome, (iii) impaired hormonal regulation, (iv) decline chlorophyll photosynthesis. Considering that, we suggested targeting redox regulatory mechanisms could be beneficial improving tolerance plants; however, antioxidant activities highly dependent on species, tissue, type, dose. also indirectly reduces altering productivity. However, MP-induced negative vary presence surface functional groups particle sizes. end, utilization agronomic approaches, including application regulators, biochar, replacing plastic mulch with crop residues, diversification, biological degradation, ameliorate The efficiency these methods MP-type-specific dose-dependent.

Microplastics as Emerging Food Contaminants: A Challenge for Food Safety

International Journal of Environmental Research and Public Health, Год журнала: 2022, Номер 19(3), С. 1174 - 1174

Опубликована: Янв. 21, 2022

Microplastics (MPs) have been identified as emerging environmental pollutants classified primary or secondary based on their source. Composition, shape, size, and colour, among other characteristics, are associated with capacity to access the food chain risks. While impact of MPs has received much attention, risks for humans derived from dietary exposure not yet assessed. Several institutions researchers support that current knowledge does supply solid data complete a risk characterization MPs. The aim this paper is review about in foods discuss challenges gaps analysis. presence beverages worldwide observed, but most authors considered be only insufficient questionable quality mainly because outstanding lack consensus standardized quantifying method unified nomenclature.

Occurrence of Microplastics in Most Consumed Fruits and Vegetables from Turkey and Public Risk Assessment for Consumers

Life, Год журнала: 2023, Номер 13(8), С. 1686 - 1686

Опубликована: Авг. 4, 2023

Microplastics are transferred to humans through the food chain by consuming contaminated with microplastics. However, knowledge about risks of dietary exposure for these particles is very limited. Moreover, only a few studies on microplastic pollution in fruit and vegetables have been carried on. Thus, this study aims investigate presence microplastics some most consumed fruits (pear (Pyrus communis), apple (Malus domestica), tomato (Solanum lycopersicum), onion (Allium cepa), potatoes tuberosum), cucumber (Cucumis sativus)) from Turkey evaluate potential risk consumers. Fruits vegetable samples were purchased different markets fruiterer (two each) Muğla province, Southwest Turkey. Microplastic extraction processes out edible parts samples.

Microencapsulation is an advanced methodology for the protection, preservation, and/or delivery of active materials in a wide range industrial sectors, such as pharmaceuticals, cosmetics, fragrances, paints, coatings, detergents, food products, and agrochemicals. Polymeric have been extensively used microcapsule shells to provide appropriate barrier properties achieve controlled release encapsulated ingredient. However, significant limitations are associated with capsules, including undesired leaching nonbiodegradable nature typically polymers. In addition, energy cost manufacturing microcapsules important factor be considered when designing systems corresponding production processes. Recent factors linked UN sustainability goals modifying how microencapsulation should designed pursuit "ideal" that efficient, safe, cost-effective environmentally friendly. This review provides overview advances microencapsulation, emphasis on sustainable designs. The key evaluation techniques assess biodegradability microcapsules, compliance recently evolving European Union requirements, also described. Moreover, most common methodologies fabrication presented within framework their demand. promising designs highlighted suitability toward meeting current design requirements stringent regulations, tackling ongoing challenges, limitations, opportunities.

Heliyon, Год журнала: 2024, Номер 10(6), С. e28291 - e28291

Опубликована: Март 1, 2024

Plastics are becoming common environmental pollutants. Plants behave as access routes for plastics in the trophic chain since they can adsorb particles through their roots or on surfaces. In this review, various methods sample preparation and analytical plastic isolation identification from vegetables, fruits, seedlings were discussed. The effects that have them also addressed. All of studies offer convincing proof micro nano already exist fruits easily enter into a variety effects. Since most been conducted under strictly controlled conditions using standard plastics, more tests environmentally realistic required to ensure literature applicable. Also, vegetables need be tested identify number currently there that, when consumed, could harm human health.
