In this study, natural hematite (Fe<sub>2</sub>O<sub>3</sub>) was employed as a CW substrate (H-CWs) for the first time to drive anaerobic ammonia oxidation coupled with iron(III) reduction (Feammox). Compared to gravel constructed wetlands (G-CWs), ammonia removal was enhanced by 38.14% to 54.03% and nitrous oxide (N<sub>2</sub>O) emissions were reduced by 34.60% in H-CWs. The synergistic removal of ammonia and nitrate by H-CWs also resulted in the absence of ammoxidation by-products. Inhibitor and <sup>15</sup>N isotope tracer incubations showed that Feammox accounting for approximately 40% of all ammonia removal in the H-CWs. The enrichment of iron phosphate (Fe<sub>3</sub>Fe<sub>4</sub>(PO<sub>4</sub>)<sub>6</sub>) promoted the accumulation of the Feammox intermediate compound FeOOH. Microbial nanowires were observed on the surface of H-CW substrates as well, suggesting that the observed biological ammoxidation was most likely related to extracellular electron transfer (EET). Microbial and metagenomics analysis revealed that H-CWs elevated the integrity and enhanced the abundance of functional microorganisms and genes associated with nitrogen metabolism.

Optical analysis-based quantitative methods have been acknowledged as effective and rapid approaches for quantifying NP concentrations in laboratory-scale studies. Herein, we compared three commonly used optical response indicators, namely fluorescence intensity (FI), ultraviolet absorbance, and turbidity, to assess their performance in quantifying NPs. Furthermore, orthogonal experiments were conducted to evaluate the influence of various water quality parameters on the preferred indicator-based quantification method. The results revealed that FI exhibits the highest correlation coefficient (> 0.99) with NP concentration. Notably, the limit of quantification (LOQ) for various types of NPs is exceptionally low, ranging from 0.0089 to 0.0584 mg/L in ultrapure water, well below environmentally relevant concentrations. Despite variations in water quality parameters such as pH, salinity, suspended solids (SS), and humic acid, a robust relationship between detectable FI and NP concentration was identified. However, an increased matrix, especially SS in water samples, results in an enhanced LOQ for NPs. Nevertheless, the quantitative method remains applicable in real water bodies, especially in drinking water, with NP LOQ as low as 0.0157–0.0711 mg/L. This exceeds the previously reported detectable concentration for 100 nm NPs at 40 µg/mL using surface-enhanced Raman spectroscopy. This study confirms the potential of FI as a reliable indicator for the rapid quantification of NPs in aqueous environments, offering substantial advantages in terms of both convenience and cost-effectiveness. <span> <span> <img alt=\"\" src=\"https://static-content.springer.com/image/MediaObjects/11783_2024_1821_Fig1_HTML.jpg\"/> </span> </span></p>","PeriodicalId":12720,"journal":{"name":"Frontiers of Environmental Science & Engineering","volume":null,"pages":null},"PeriodicalIF":6.4,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140006045","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Carcinogenic and non-carcinogenic health risks were computed based on the HMs concentration in the soil and rice grain, with Pb, Cr, and Ni identified as posing a high risk to human health. Monte Carlo simulation, the solubility-free ion activity model (FIAM), and severity adjusted margin of exposure (SAMOE) were employed to predict health risk. FIAM hazard quotient (HQ) values for Ni, Cr, Cd, and Pb were > 1, indicating a significant non-carcinogenic risk. SAMOE (risk thermometer) results for contaminated zones ranged from low to moderate risk (Cr<sub>SAMOE</sub>: 0.05, and Ni<sub>SAMOE</sub>: 0.03). Fuzzy-TOPSIS and variable importance plots (from random forest) showed that Ni and Cr were mostly responsible for the toxicity in the rice plant, respectively.

The positive matrix factorization model for the source apportionment identified coal mining and transportation as the predominant sources of HMs. Spatial distribution analysis indicated higher contamination near mining sites as compared to distant sampling sites.
