Shuitu Baochi Xuebao, 2011 对大宝山矿区自然定居和人工种植的13种优势植物根际土壤污染状况及其对重金属的富集特征进行研究。结果表明,大宝山矿区土壤受重金属Cd、Pb、Zn、Cu污染,其中以Cd、Cu的污染最为严重。在调查的13种优势植物中,铺地黍地上部分的Pb含量达到1 214.00mg/kg,泡桐叶中Cu含量达到1 024.80mg/kg,超过了Pb和Cu超富集植物含量的临界值(1 000mg/kg);其运转系数分别为1.77,13.74,都大于1.0,符合超富集植物的标准,表明铺地黍可能是Pb的超富集植物 ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Atomically dispersed iron–nitrogen–carbon (Fe‐N‐C) catalysts have emerged as promising alternatives for oxygen reduction reaction (ORR) owing to their highly atomic utilization. However, maintaining both Fe atomic dispersion and dense Fe‐Nx sites (typically below 2 wt%) in Fe‐N‐C catalysts is still a key challenge.

Functional Ecology, Volume 40, Issue 5, Page 1428-1442, May 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract The stoichiometric imbalance caused by nitrogen (N) deposition typically exacerbates phosphorus (P) limitation in plants. However, it remains unclear whether this effect extends to soil microbes, particularly those in the rhizosphere.

Zhejiang Daxue xuebao. Lixue ban, 2006 实验考察了使用钝顶螺旋藻富集与降解溶液中的阴离子表面活性剂(LAS).结果表明，溶液中不同浓度LAS存在下，钝顶螺旋藻的生长符合逻辑斯谛克方程；钝顶螺旋藻对LAS具有一定的富集能力，当LAS的质量浓度为0.5、1、2 mg/L时，24 h时富集量达到最大，分别为2. 43、4. 83、10.12 mg/g；钝顶螺旋藻对LAS也具有一定的降解能力，当LAS的质量浓度分别为0.

High‐Value Targeted Conversion of Copper Slag as LiFePO4 Material for Lithium‐Ion Batteries
Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT The massive stockpiling of copper slag (CS) presents severe environmental and resource‐waste challenges. Existing strategies for CS valorization typically yield low‐value‐added products. Herein, we propose an innovative hierarchical regulation approach to transform CS into high‐performance LiFePO4 (LFP) cathode materials.

Shuitu Baochi Xuebao, 2005 研究了次降雨过程中红壤小流域5种不同土地利用方式土壤N,P养分流失特征。结果表明,在降雨后,花生地、花-橘间作、橘园、板栗园和水田5种利用方式表层土壤N,P养分含量均有不同程度下降,其中花生地N,P含量下降最为明显,水田N,P含量降幅则最小;不同形态养分平均降幅依次为有效氮(5.49%)、有效磷(5.25%)、全氮(1.45%)、全磷(0.59%)。各样地地表径流中水溶态N,P养分含量花生地明显高于其他样地,而泥沙中N,P养分含量则以水田最高;各样地侵蚀泥沙中N,P养分有明显的富集现象,板栗园和橘园N ...

Shuitu Baochi Xuebao, 2008 通过盆栽实验,以小白菜(上海青)、大白菜和萝卜为指示作物,研究了酸雨作用下Cu,Zn,Pb,Cd,Cr和Ni复合污染物在土壤-作物系统中的吸收与富集情况。结果表明,酸雨-重金属复合污染处理使Cu,Pb,Cr和Ni在蔬菜中积累量明显高于对照处理;Zn和Cd一般只有在复合污染处理中外源Zn或Cd含量较高时才明显高于对照处理。与对照相比,酸雨-重金属复合污染处理使Pb和Ni的富集系数增大,Cu的富集系数多数情况下增大,Cd的富集系数多数情况下减小,Zn和Cr富集系数的变化在不同蔬菜之间存在较明显的差异 ...

Shuitu Baochi Xuebao, 2007 采用室内培养技术研究了向日葵幼苗对Cu、Pb的富集能力与耐受性。结果表明:向日葵幼苗对Pb、Cu具有很强的富集能力,根是主要的富集器官,Cu由根向茎叶运输能力大于Pb。低浓度Pb、Cu刺激了幼苗营养生长;在高浓度条件下,除Pb组外,其它处理均抑制向日葵幼苗的营养生长。Pb、Cu抑制了幼苗根系活力,刺激了幼苗茎叶脯氨酸的生成,改变幼苗茎叶、根蛋白质含量分配水平。Pb与Cu交互作用对幼苗营养生长和生理生化反应具有协同作用。向日葵属于重金属富集植物,对Pb具有很强的耐受性,可以用于修复被Pb污染的土壤。
