However, its effectiveness depends on the selection of suitable microalgae species. In this study, four algal species (Chlorella sorokiniana, Chlorella vulgaris, Scenedesmus ecornis, and Strombomonas sp.) were evaluated for their ability to remove pollutants from secondary treated domestic wastewater using multi-soil-layering (MSL) technology. Among the four strains tested, Chlorella sorokiniana exhibited the highest algal density (2.832 ± 0.187 × 107 cells/mL) and outperformed other species with phosphorus, nitrogen, and COD removal rates exceeding 82.01%, 63.64%, and 61.09% respectively. In addition, Chlorella sorokiniana had a higher total chlorophyll content of 31.11 µg. L-1 (Chl a: 15.47 ± 0.148 µg. L-1; Chl b: 15.642 ± 0.052 µg. L-1) than other species. Physiological analyses of proline and glycine betaine indicated that the two Chlorella strains experienced lower stress levels, which facilitated an accelerated bioremediation process compared to other Chlorophyta, namely Scenedesmus ecornis and Strombomonas sp. The efficiency of C. sorokiniana in the treatment of secondary treated wastewater from MSL, combined with its maximum biomass production, underlines its potential for industrial application.

Scanning electron microscopy images confirmed a porous, fibrous structure that transformed post-adsorption, indicating successful dye uptake. X-ray diffraction analysis identified crystalline cellulose forms enhancing adsorption stability, while energy dispersive X-ray analysis confirmed a significant increase in carbon content and incorporation of CV dye elements. Brunauer-Emmett-Teller analysis highlighted a moderate surface area of 6.42 m2/g, suitable for external adsorption processes. Kinetic studies revealed that adsorption equilibrium was achieved within 70 min, with a second-order model providing the best fit, indicating chemisorption. Optimal adsorption occurred at a biosorbent dose of 0.08 g, with efficiency diminishing at higher CV concentrations due to site saturation. Adsorption was most effective above the point of zero charge (pH 5.4), with temperature increases further enhancing adsorption capacity. Langmuir isotherm analysis suggested monolayer adsorption on a homogenous surface. The maximum adsorption capacity of the adsorbent was determined to be 44.24 and 66, 28 mg/g in the linear and nonlinear forms, respectively, highlighting its significant potential for the efficient removal of CV dye from aqueous solutions. Thermodynamic evaluations confirmed an endothermic and spontaneous process. Statistical modeling validated the system's reliability, offering a predictive framework for optimizing conditions.

Researchers measured PM concentrations in the air and on the leaves of Picea abies, Quercus robur, and Corylus avellana, along with photosynthetic indicators (Fv/Fm ratio and performance index). The study found significant differences in pollution intensity across areas with varying levels of human activity. P. abies, an evergreen species, accumulated the highest PM levels (>200 μg/cm2), while Q. robur had the highest accumulation among deciduous trees (>50 μg/cm2). Trace elements such as Fe, Cu, Zn, Sr, and Cd were detected, with C. avellana being the most efficient in accumulating Cd (up to 7.5 mg/kg). The accumulation of pollutants correlated with reduced photosynthetic efficiency in trees closest to pollution sources. The findings suggest that strategically planting specific tree species can help mitigate air pollution in national parks and protect sensitive vegetation. Future research should explore the long-term effects of PM on forest health and the role of different species in phytoremediation.","PeriodicalId":14235,"journal":{"name":"International Journal of Phytoremediation","volume":" ","pages":"448-461"},"PeriodicalIF":3.4,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142675785","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}
