To achieve high-precision results, the Artificial Bee Colony (ABC) algorithm, a robust meta-heuristic optimization technique inspired by the foraging behavior of honeybees, was utilized to minimize the error between experimental data and predicted models to optimize the accumulation of key elements including cobalt (Co), strontium (Sr), antimony (Sb), vanadium (V), phosphorus (P), lanthanum (La), magnesium (Mg), titanium (Ti), aluminum (Al), and scandium (Sc). The research focused on three NP species-Musk thistle (MT), curly dock (CD), and Juncus (JS)-collected from a geothermal hot spring area. Methodological validation was performed through comparative statistical analysis and the calculation of bioconcentration factor (BCF) and translocation factor (TF) to assess phytoremediation efficiency. The ABC optimization results revealed that MT exhibited the most significant accumulation capacity, particularly for Mg, reaching a peak concentration of 3,910 mg/kg<sub>dw</sub> in the leaves. The concentration range (lowest to highest value) was between 0.01 (for La) and 3,910 mg/kg<sub>dw</sub> for the studied plants. Principal component analysis (PCA) corroborated these findings, explaining cumulative variances of 80.4% (MT), 89.4% (CD), and 76.4% (JS). The innovation of this study lies in the application of the ABC algorithm to the field of phytomining, which offers a more dynamic and flexible alternative to traditional regression-based models. The primary advantage of this proposed method is its superior global search capability and ability to handle multi-elemental interactions with high predictive accuracy. However, a potential disadvantage remains the computational complexity and the requirement for fine-tuning control parameters to ensure consistent convergence.

Therefore, the development of sustainable and cost-effective remediation strategies is essential. Phytoremediation, an environmentally compatible approach that utilizes plants and their associated biological processes to reduce contaminant mobility, bioavailability, and toxicity, has gained increasing attention as an alternative to conventional remediation techniques. Among potential phytoremediation candidates, invasive plant species (IPS) have attracted interest due to their rapid growth, high biomass production, extensive root systems, physiological plasticity, and tolerance to stressful environments, including heavy metal contamination. Species such as <i>Alternanthera philoxeroides</i>, <i>Arundo donax</i>, <i>Eichhornia crassipes</i>, and <i>Pistia stratiotes</i> have demonstrated potential for metal uptake, accumulation, immobilization, or tolerance in contaminated ecosystems. This review critically examines the role of invasive plants in heavy metal phytoremediation by evaluating the physiological, biochemical, and ecological traits that influence remediation outcomes. Key mechanisms, including phytoextraction, phytostabilization, rhizosphere-mediated processes, and plant-microbe interactions, are discussed using evidence from contaminated soil and aquatic environments. The potential advantages of invasive plants, particularly their high biomass production and environmental adaptability, are evaluated alongside ecological concerns associated with their utilization. Importantly, invasion success does not necessarily translate into remediation success, and the effectiveness of invasive plants depends on contaminant characteristics, ecosystem conditions, and management practices. Major challenges, including uncontrolled spread, ecosystem disruption, contaminated biomass management, and limited field-scale validation, are critically assessed. Overall, invasive plants represent context-dependent remediation resources rather than universal solutions.

The 60:40 dilution exhibited the highest algal growth rate (μ = 0.65 day<sup>-1</sup>), cell viability and chlorophyll-a concentration, accompanied by balanced antioxidant enzyme activity (SOD, CAT, GST, and Gt) and low malondialdehyde (MDA) levels. Principal component analysis indicated a strong association between antioxidant defence and nutrient removal. Post-cultivation analysis of sewage water showed reduced ionic load and COD, along with increased DO, indicating improved water quality for sewage-fed aquaculture. A separate experiment on sewage dilution with rain water (60:40) showed nutrient removal efficiency similar to lab grade water, highlights the potential for field applicability.</p>","PeriodicalId":14235,"journal":{"name":"International Journal of Phytoremediation","volume":" ","pages":"1-13"},"PeriodicalIF":3.1,"publicationDate":"2026-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148955408","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}
