Abstract Extensive anthropogenic activity has led to the accumulation of organic and inorganic contaminants in diverse ecosystems, which presents significant challenges for environment its inhabitants. Utilizing microalgae as a bioremediation tool can present potential solution these challenges. Microalgae have gained attention promising biotechnological detoxifying environmental pollutants. This is due their advantages, such rapid growth rate, cost-effectiveness, high oil-rich biomass production, ease implementation. Moreover, microalgae-based remediation more environmentally sustainable not generating additional waste sludge, capturing atmospheric CO 2 , being efficient nutrient recycling algal production biofuels high-value-added products generation. Hence, achieve sustainability's three main pillars (environmental, economic, social). Microalgal mediate contaminated wastewater effectively through accumulation, adsorption, metabolism. These mechanisms enable reduce concentration heavy metals levels that are considered non-toxic. However, several factors, microalgal strain, cultivation technique, type pollutants, limit understanding removal mechanism efficiency. Furthermore, adopting novel technological advancements (e.g., nanotechnology) may serve viable approach address challenge refractory pollutants process sustainability. Therefore, this review discusses ability different species mitigate persistent industrial effluents, dyes, pesticides, pharmaceuticals. Also, paper provided insight into nanomaterials, nanoparticles, nanoparticle-based biosensors from immobilization on nanomaterials enhance open new avenue future advancing research regarding biodegradation

Phytoremediation of microplastics by water hyacinth

Environmental Science and Ecotechnology, Год журнала: 2025, Номер 24, С. 100540 - 100540

Microplastics have emerged as pervasive environmental pollutants, posing significant risks to both terrestrial and aquatic ecosystems worldwide. Current remediation strategies-including physical, chemical, microbial methods-are inadequate for large-scale, in situ removal of microplastics, highlighting the urgent need alternative solutions. Phytoremediation, an eco-friendly cost-effective technology, holds promise addressing these challenges, though its application microplastic pollution remains underexplored. Here we show capacity Eichhornia crassipes (water hyacinth), a fast-growing, floating plant, remove microplastics from contaminated water. Our results that within 48 h, water hyacinth achieved efficiencies 55.3 %, 69.1 68.8 % 0.5, 1, 2 μm polystyrene particles, respectively, with root adsorption identified primary mechanism. Fluorescence microscopy revealed extremely large abundant caps, featuring total surface area exceeding 150,000 mm2 per serve principal sites entrapment microplastics. Furthermore, unique "vascular ring" structure stem prevents translocation aerial tissues, safeguarding leaves potential downstream applications. This study offers first microstructural insight into mechanisms underpinning hyacinth's exceptional resilience, providing promising framework developing phytoremediation strategies mitigate ecosystems.

Pollution characteristics of microplastics in greenhouse soil profiles with the long-term application of organic compost

Resources Environment and Sustainability, Год журнала: 2024, Номер 17, С. 100165 - 100165

Organic composts are significant sources of microplastic (MP) pollution in soils, and their input is much higher greenhouse agriculture than open-field agriculture. However, how long-term compost application affects MPs soil profiles remains unclear. This study examined characteristics chicken manure earthworms, exploring the impacts on accumulation vertical migration 0–100 cm depth through a 15-year experiment. Microplastics abundance was 3965 items kg−1 compost, 191–248 compost-amended 2.73–4.52 individual−1 earthworms from soils; latter two increased significantly with were unamended soils. Soil amendment contributed 45.4% total. The proportion <2 mm (49.7%) less soils (65.5%) (65.4%). size decreased increasing depth. polymer types shapes composts, exhibited similarities, mainly including polyethylene polypropylene fragments fibers. Compost-derived complex weathering morphology adhered to mineral colloids. Therefore, originating gradually weathered degraded into smaller particles migrated deeper soil, maybe resulting more serious ecological issues.

The pervasiveness of microplastics (MPs) in terrestrial and aquatic ecosystems has become a significant environmental concern recent years. Because their slow rate disposal, MPs are ubiquitous the environment. As consequence indiscriminate use, landfill deposits, inadequate recycling methods, MP production accumulation expanding at an alarming rate, resulting range economic, social, repercussions. Aquatic organisms, including fish various crustaceans, consume MPs, which ultimately consumed by humans tertiary level food chain. Blocking digestive tracts, disrupting behavior, reducing reproductive growth entire living organisms all consequences this phenomenon. In order to assess potential impacts resources required for life plastic product, importance cycle assessment (LCA) circularity is underscored. MPs-related ecosystem degradation not yet been adequately incorporated into LCA, tool evaluating performance product technology cycles. It technique that designed quantify effects from its inception demise, it frequently employed context plastics. control necessary due growing pose as newly emergent threat. This use. paper provides critical analysis formation, distribution, methods used detecting MPs. on human health also discussed, posed great challenge conduct LCA related socio-economic management discussed. paves way understanding ecotoxicological emerging threat associated issues limits impact plastic.
