概括

来自钢铁 (IS) 和织 (T) 工业的工业废水,当用于灌作物时,会带来风险. 这项研究评估了土壤污染,生态风险和在小麦谷物中潜在的有毒金属 (PTM) 积累,为更安全的农业推低积累基因型.

科学领域:

环境科学环境科学
农业科学农业科学
毒理学毒理学毒理学

背景情况:

来自铁钢 (IS) 和织 (T) 部门的工业废水是主要的全球污染物,含有潜在有毒金属 (PTM).
在发展中国家,淡水短缺推动了用这些废水灌农田的普遍做法.
评估这种做法对环境和人类健康的影响至关重要.

研究的目的:

调查IS和T排水中的PTM污染及其对灌土壤的影响.
评估与废水灌相关的生态风险.
评估小麦谷物中的PTM积累,评估人类健康风险,确定合适的小麦基因型.

主要方法:

用IS和T废水灌的土壤中PTM,酸,和有机物质的分析与对照.
丰富系数,地质积累指数,潜在生态风险指数和修改后的潜在生态风险指数的计算.
对30种小麦基因型的谷物中PTM积累的评估和用于基因型选择的主要成分分析 (PCA) 的应用.

主要成果:

废水灌显著增加了土壤营养素和PTMs. 在IS和T排水中发现了大量的PTM污染,IS的Ni>Cr>Co>Cd>Pb>Zn>Mn和T的Co>Cd>Ni>Cu>Cr.
生态风险评估表明T灌土壤的风险非常高,IS灌土壤的风险很大,主要是由于Cd,Co和Ni.
在30种小麦基因型中观察到PTM积累的显著差异,与对照物相比,IS和T废水导致较高的谷物PTM,尽管具体的金属积累模式在废水类型之间有所不同.

结论:

IS和T废水带来了严重的土壤污染和生态风险,特定的PTM推动了这些风险.
小麦基因型在废水灌下在谷物中呈现PTM积累的不同潜力.
建议小麦基因型具有较低的PTM积累对于减轻受影响的农业生态系统中对作物质量和人类健康的风险至关重要.

Types of Toxins

Types of Toxins

Humans continually engage with an environment rich in potentially harmful chemicals. These are introduced to our bodies through inhalation, ingestion, or skin contact. These chemicals exist in various forms, such as air and environmental pollutants, agricultural chemicals, organic solvents, and heavy metals.
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.
Environmental pollutants like...

The Soil Ecosystem

The Soil Ecosystem

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:

Responses to Drought and Flooding

Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.
