 摘要： This paper summarizes the mechanisms and environmental effects of interactions between microplastics and surfactants: surfactants adsorb onto microplastics surfaces through hydrophobic interactions and electrostatic forces, changing their surface properties and transport behavior. In addition, microplastics act as carriers influencing surfactant distribution. Environmental factors (pH, ionic strength, etc.) significantly regulate this process. Current research still has limitations in areas such as desorption kinetics and combined pollution effects, necessitating in-depth studies under environmentally relevant conditions to provide a basis for risk assessment.

 摘要： [Objectives] To explore the phylogenetic diversity of wetlands at the source of the Qin River and provide data reference for future research. [Methods] Taking survey data (July, 2016) of plants in wetlands at the source of Qin River as research object, this study utilizes Phylocom 4.2 to construct plant (in wetlands at the source of Qin River) genealogical tree for 72 non-angiosperm species within research area, besides, the paper adopts Pedigree diversity index (PD), community pedigree structure index (net Relatedness index, NRI and Nearest Taxon Index, NTI) to analyze pedigree diversity and pedigree structure of plants in wetlands at the source of Qin River. This paper is going to explain the scientific question: pedigree diversity, pedigree β diversity, and pedigree structure of plants in wetlands at the source of Qin River, in order to study on relatedness and stability of community. [Results] The effect of habitat filtration will result in similar species adaptation and close genetic relationships in the community, manifesting as genealogy aggregation. On the contrary, the effect of competitive exclusion can lead to distant species’ genetic relationships in the community, manifesting as genealogy divergence. In this study, there was a tendency of aggregation among the species in sample plot S5, which indicated that the effect of habitat filtration was dominant in this plot, and in S2 and S6 the species had a decentralized trend. The NRI and NTI values in other plots were different in the positive and negative. [Conclusions] This research serves as an initial exploration of the phylogenetic diversity and community assembly mechanisms in the wetlands at the source of Qin River. Further studies incorporating environmental factors and human activities could provide deeper insights into community ecology phenomena and assembly mechanisms.

 摘要： Pharmaceutical-Food Homologous Plant-Derived Carbon Dots (P-CDs) have emerged as revolutionary nanomaterials in environmental pollutant management, demonstrating transformative potential for green chemistry and sustainable material applications. These carbon dots establish an innovative technical framework by integrating dual "detection-remediation" functionalities through eco-friendly synthesis and high-value conversion of medicinal-edible plants and agroforestry waste. Their core advantages originate from structural templating effects induced by natural functional groups (polyphenols, amino acids) in plant precursors combined with heteroatom self-doping, which synergistically optimizes optical properties. This combination achieves quantum yields ranging from 3.06% to 84.9% and detection sensitivities spanning nanomolar to micromolar concentrations. In pollutant detection applications, P-CDs enable ultrasensitive identification of heavy metals (Hg²⁺, Cu²⁺, Fe³⁺) and organic contaminants (pesticides, antibiotics) through multi-mechanistic interactions including static quenching (SQ), dynamic quenching (DQ), and Förster resonance energy transfer (FRET). However, technological translation faces critical challenges including quantum yield heterogeneity (>40-fold variation), matrix interference in complex environmental samples (signal drift exceeding 12%), and scalability-related process inconsistencies. Future research priorities should focus on three key areas: standardization of synthesis protocols, development of surface passivation strategies (e.g., SiO₂ encapsulation), and optimization of heterojunction designs to enhance interference resistance. The integration of in situ characterization techniques (particularly X-ray absorption spectroscopy) with machine learning-driven parameter optimization could significantly refine detection-remediation synergies. Concurrently, establishing a comprehensive lifecycle assessment framework becomes imperative for evaluating environmental impacts and scalability potential. This technology pioneers a sustainable paradigm for pollution control by bridging the gap between nanomaterial innovation and industrial deployment, thereby accelerating progress toward global ecological security objectives.
