Consequently, the development of effective, economically feasible, and sustainable remediation strategies has emerged as a key research priority in environmental biotechnology. In this context, mycoremediation is a fungal based bioremediation approach that exploits the biological capabilities of fungi such as biodegradation, biosorption, enzymatic detoxification, and symbiotic interactions. It has gained increasing attention as a low cost and environmentally friendly alternative for pollutant removal. This review provides a comprehensive and critical synthesis of the mechanisms underlying mycoremediation, with particular emphasis on ligninolytic and oxidative enzymatic pathways, fungal metabolic functions, and pollutant specific transformation processes. The performance of representative fungal species, including <i>Phanerochaete chrysosporium, Trametes versicolor, Pleurotus ostreatus</i>, <i>Aspergillus niger</i>, and <i>Ganoderma lucidum</i>, is comparatively evaluated across major pollutant groups such as heavy metals, pesticides, hydrocarbons, synthetic dyes, and pharmaceutical contaminants, drawing on recent quantitative findings. In addition, mycoremediation is assessed from environmental, economic, and social sustainability perspectives, with attention to its feasibility for large scale applications. Key limitations including enzyme instability, environmental sensitivity, biomass scalability, and microbial competition are critically discussed. Finally, the integration of advanced biotechnological tools such as genetic engineering, multi omics approaches, nanotechnology, and microbial consortia is highlighted as a promising pathway to enhance system robustness and field applicability. Overall, this review positions mycoremediation as a versatile and scalable component of future sustainable environmental management strategies, with significant potential for ecosystem restoration and public health protection.</p></div>","PeriodicalId":546,"journal":{"name":"Environmental Sciences Europe","volume":"38 1","pages":""},"PeriodicalIF":6.0,"publicationDate":"2026-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1186/s12302-026-01365-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147737644","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, current chitosan/acrylic acid-based remediation materials often have limitations in terms of efficiency, stability, and toxicity. In this study, graphene oxide (GO) and carboxylated graphene oxide (GC) were used as modified materials to synthesize two novel hydrogels: polyacrylic acid/chitosan/graphene oxide (PCG) and polyacrylic acid/chitosan/carboxylated graphene oxide (PCC). The adsorbents were characterized using SEM, FTIR, and BET tests. A comprehensive series of adsorption experiments was conducted, optimizing parameters such as pH, temperature, initial Pb(Ⅱ) concentration, and dynamic column. The characteristics of the hydrogels indicate that –COOH and –OH are the primary functional groups; their 3D porous structure, mesoporous structure, and large specific surface area facilitate heavy metal adsorption. Under optimal conditions (pH 5, 25 °C, 0.2 g/L dosage, 500 mg/L initial Pb(Ⅱ) concentration), PCG and PCC achieved maximum Pb(Ⅱ) adsorption capacities of 323.83 and 446.09 mg/g, respectively—demonstrating superior efficiency. PCC demonstrated excellent stability and reusability, retaining an adsorption capacity of 367.44 mg/g after four cycles. It also displayed exceptional acid resistance (adsorption capacity reaches 168.32 mg/g at pH 1.0) and negligible interference (&lt; 5%) from coexisting common ions (K⁺, Na⁺, Ca²⁺, Mg²⁺). Dynamic column experiments revealed that PCC could effectively treat simulated wastewater containing 50 mg/L Pb(II) for over 900 min while maintaining a 95% removal efficiency. Adsorption kinetic analyses using the PFO and PSO models indicated that chemisorption was the dominant mechanism in the adsorption process. Meanwhile, Langmuir and Freundlich adsorption modeling showed that monolayer adsorption on homogeneous surfaces was the predominant surface adsorption behavior. Boasting relatively low production costs and superior adsorption performance, the hydrogels presented herein offer a promising, effective, economical, and eco-friendly solution for Pb(Ⅱ) remediation in aqueous systems.</p></div>","PeriodicalId":546,"journal":{"name":"Environmental Sciences Europe","volume":"38 1","pages":""},"PeriodicalIF":6.0,"publicationDate":"2026-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1186/s12302-026-01342-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147737503","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The key idea is that target forest communities could naturally migrate from countries south of Germany—where the climatic conditions expected in Germany’s future have already existed for centuries. These specific forest communities have the unique ability to recreate their characteristic biocenosis in Germany and develop their typical biodiversity. The target forest types (TFT) thus serve as essential components in establishing forest development targets for ecological forest conversion. The BERN (Bioindication for Ecosystem Regeneration towards Natural conditions) database (https://github.com/bern-model/BERN) serves as the basis for the modeling. In total, 1483 plant communities (including 642 natural wood communities) were evaluated from data collections of largely undisturbed sites, preferably those dating before 1980. For this investigation, 691 phytosociological publications have been evaluated up to now, containing a total of 150,643 relevés with corresponding descriptions of the ecoclimatic and edaphic site factors from Central and Southern Europe. The oldest representative published synoptic table serves as a reference for a community. Each community is characterized by ranges for fuzzy limits of pH value, base saturation, carbon to nitrogen ratio, volumetric soil water content, continentality index, climatic water balance, growing season length and photosynthetically active radiation from reference measured data. For the regionalization of global warming-adapted TFTs, a climatic classification for Germany is proposed, taking projected global warming into account. The parameters growing season length (period of days with &gt; 10 °C) and climatic water balance in the growing season are sufficient to establish a significant correlation to the occurrence of forest community groups (compiled according to main tree species). The evaluation of the measurement data (time series 1991–2020) and a simulation run of the RCP8.5 scenario (time series 2051–2080) resulted in a range of the Growing season length from 55 to 246 d a&lt;sup&gt;−1&lt;/sup&gt; and a range of the climatic water balance in the growing season from − 47 to + 291 mm/month. The resulting 38,200 edaphic/climatic combination types (= ”habitat types”) were assigned a total of 147 different TFTs. If multiple communities were possible at a single site type, an alternative assessment was conducted using 10 additional site factors.

The objective of this study is to scrutinize the association between environmental policy stringency (EPS), green energy, and EFP in the United States. To achieve this, innovative methodologies (namely, wavelet quantile correlation and the causality approach) are employed, utilizing data from 1990 to 2022. The findings reveal that EPS warrants a substantial reduction in the EFP in the US. Although notable heterogeneous effects exist, the evidence suggests a strong negative relationship between EPS and EFP. Akin to the impact of EPS, green energy consumption produces a varying negative and positive impact on EFP over the distributions. Nevertheless, a critical observation herein is the predominant negative contribution of green energy consumption to EFP. Except in the lowest and uppermost quantiles, the contributions of green energy thereafter remain insufficient to engender ecological sustainability. Further findings reveal that both green energy and EPS significantly Granger-caused EFP across the time and quantile dimensions.
