Comparative Analysis of Chernozem Microbiome Resistance to Toxic Heavy Metals (Co²⁺, Cu²⁺, Zn²⁺, Ni²⁺) under Individual and Pairwise Exposure

本研究表明,尽管原生黑土微生物组对单一重金属(Co²⁺、Ni²⁺、Zn²⁺、Cu²⁺)表现出不同的抗性,但二元混合物会诱发严重的协同毒性,其程度剧烈超过加和预测,从而揭示了现有的单金属风险评估严重低估了多金属污染的危害。

Biodegradable microplastic type and wheat-straw addition shape soil CO₂ emissions: links to dissolved organic matter turnover and microbial carbon allocation

本研究表明,生物可降解微塑料和麦秆的添加通过涉及溶解有机物周转和微生物碳分配的复杂相互作用,显著改变了土壤二氧化碳排放量,揭示了呼吸作用的增强并不一定与更高的溶解有机碳浓度、单细胞基因丰度或总示踪剂同化量相关联。

Soundscape categories shape recreational responses across independently characterized bamboo forest settings: a two-phase audio– visual experiment

这项两阶段视听实验表明,声学条件显著影响竹林中的休闲反应,其中自然声音诱发了最高的主观放松感与愉悦感,而交通噪声产生了最强的负面影响,尽管这些主观偏好与脑电图(EEG)测量结果之间的相关性较弱,且主要受感知愉悦度和烦恼度的调节。
