概括
产生的水 (PW) 泄漏会损害土壤. 使用Brewster sideoats grama (BSG) 的种子发芽测试有效评估了补救措施,发现盐度而不是化物是主要的土壤毒素.
科学领域:
- 环境科学 环境科学
- 土壤科学 土壤科学
- 生态毒理学 生态毒理学
背景情况:
- 陆上产生的水 (PW) 泄漏会对土壤质量产生负面影响.
- 需要有效的补救策略来减轻PW污染.
- 可靠的生物测试对于评估土壤修复技术的有效性至关重要.
研究的目的:
- 开发一种实用的种子发芽试验,用于评估受PW污染的土壤修复.
- 评估PW及其主要决定因素 (盐度) 的毒性.
- 评估普鲁士黄色 (PY) 作为PW污染土壤的修复剂的有效性和安全性.
主要方法:
- 用两种本土草进行了种子发芽测试,分别是Brewster sideoats grama (BSG) 和圣地亚哥银蓝草 (SSB).
- 选择了BSG进行进一步测试,使用田地土壤添加PW稀释剂和同等盐度的化 (NaCl) 溶液.
- 测量了土壤电导率 (EC) 和自由化物度,以评估盐应激和潜在的普鲁士黄色 (PY) 毒性.
主要成果:
- 和NaCl都抑制了BSG的种子发芽,这表明度是主要的毒性因素.
- 普鲁士黄色 (PY) 单独不抑制种子发芽,并没有增加与PW或NaCl结合时的毒性.

Responses to Salt Stress
14.7K
Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.

The Soil Ecosystem
25.0K
Plants obtain inorganic minerals and water from the soil, which acts as a natural medium for land plants. The composition and quality of soil depend not only on the chemical constituents but also on the presence of living organisms. In general, soils contain three major components:

Testing Water Quality
396
When the quality of water for concrete preparation is uncertain, its impact on the setting time of cement and compressive strength of mortar is assessed by comparison with de-ionized or distilled water benchmarks. American Society for Testing and Materials (ASTM) C1602 requires the setting times to be within 90 minutes of the control, British Standard (BS) 3146:1980 allows a 30-minute variance in the initial setting, while British Standards European Norm (BS EN) 1008 specifies initial setting...

Seed Structure and Early Development of the Sporophyte
31.3K
Seed structures are composed of a protective seed coat surrounding a plant embryo, and a food store for the developing embryo. The embryo contains the precursor tissues for leaves, stem, and roots. The endosperm and cotyledons—seed leaves—act as the food reserves for the growing embryo.

Determining the pH of Salt Solutions
48.3K
The pH of a salt solution is determined by its component anions and cations. Salts that contain pH-neutral anions and the hydronium ion-producing cations form a solution with a pH less than 7. For example, in ammonium nitrate (NH4NO3) solution, NO3− ions do not react with water whereas NH4+ ions produce the hydronium ions resulting in the acidic solution. In contrast, salts that contain pH-neutral cations and the hydroxide ion-producing anions form a solution with a pH greater than 7. For...

The Water Cycle

The Earth’s hydrosphere includes all of the areas where the storage and movement of water occurs. Since water is the basis of all living processes, the cycling of water is extremely important to ecosystem dynamics.
