本研究在紫花苜蓿-根瘤菌共生体系的盆栽中加入硝化钠（SNP）作为一氧化氮（NO）供体和硫氢化钠（NaHS）作为硫化氢（H2S）供体的溶液，以阐明信号分子（NO和H2S）对Pb/Cd污染土壤中植物-土壤生化响应的影响，揭示外源性应用信号分子改变豆科-根瘤菌共生体系抗性的调节机制。污染土壤样品来自陕西省凤县某个冶炼厂周边（106°33′ E, 33°48′ N），主要重金属污染物是Pb和Cd。金属抗性
The use of plants to decontaminate water and soil contaminated with both organic and inorganic pollutants is a promising technology for sustainable agriculture. The aim of this work was to evaluate th
ABSTRACT Industrial and organic residues cause environmental impacts at various levels. However, these residues present potential to correct soil acidity and fertility. Considering the possibility of
The hazardous oxygenated polycyclic aromatic hydrocarbons (OPAHs) originate from combustion (primary sources) or post-emission conversion of PAHs (secondary sources). We evaluated the global distribut
Part 1 of this study summarizes data for a field investigation of contaminant concentration variability within individual, discrete soil samples ( intra-sample variability) and between closely s
