概括

含有微塑料 (MP) 和重金属 (HM) 的废水严重损害作物生长和健康. 从废水中去除MP对于减轻植物毒性和确保农业生态系统中的食品安全至关重要.

科学领域:

环境科学环境科学
农业科学农业科学
生态毒理学生态毒理学

背景情况:

城市周边农业的废水通常含有微塑料 (MP) 和重金属 (HM).
这些污染物对作物健康和农业可持续性构成重大风险.
个人护理产品是废水中的众议员的重要来源.

研究的目的:

调查废水中的重金属 (Cd,Hg,Pb) 和聚乙烯微塑料 (MPs) 对 (Capsicum annuum) 的相互作用作用.
评估这些联合污染物对植物生长,生理和重金属吸收的影响.

主要方法:

*Capsicum annuum*暴露于不同度的污染废水 (SWW) 和微塑料 (MP).
测量了植物生长参数,光合作用色素含量,可溶性蛋白质水平和氧化应激标志物 (MDA,H2O2).
分析了抗氧化酶活动和植物组织中的重金属积累.

主要成果:

植物生长,光合作用色素和可溶性蛋白质随着SWW和MP水平的增加而显著下降.
氧化应激标志物 (MDA,H2O2) 增加,而抗氧化酶活性最初上升,然后下降,表明压力和适应失败.
重金属积累在根源上占主导地位,并由MP显著增强,在高压力条件下增加了11-23%的吸收量.

结论:

废水中对MP和HM的联合暴露严重影响了胡植物生理和生长.
微塑料促进重金属的吸收,加剧了植物毒性.
废水处理以去除MP对于保护作物健康和确保农业地区的食品安全至关重要.

Responses to Salt Stress

Responses to Salt Stress

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.

Bioremediation

Bioremediation

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

Responses to Drought and Flooding

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.
