Phthalates are synthetic chemical compounds that are primarily used as plasticizers in various plastics and polymers to improve their physical properties. They are reported as ubiquitous pollutants in different spheres of the environment due to the presence of physical bonding with the polymeric matrix. In animals, including humans, they are known to cause various toxic effects. Nevertheless, less attention has been paid to phthalate induced stress in plants, since plants are equally vulnerable to their exposure as they are immobile and being an important component of the environment cannot be ignored. Moreover, due to their frequent detection in higher amounts in agricultural soils globally, significant concern has been raised about phthalate induced stress in plants over the past decade. The main sources of phthalate in agricultural soils are the use of plastic mulching, irrigation with wastewater, pesticide spraying, use of biosolids for improving soil properties, etc. From the soils, phthalates could enter into plants mainly via roots and undergo biomagnification at different trophic levels in an ecosystem. Phthalates were declared as endocrine disruptors thereby, their accumulation in edible plants raises food security concerns. Moreover, the accumulation of phthalates in plants is observed to affect germination, growth and development as well as reported to interfere with normal plant metabolism which led to modulations in the content of pigments, osmolytes, stress biomarkers and activities of antioxidative enzymes, thus reducing the yield and quality of edible plants.

邻苯二甲酸盐胁迫下植物形态生理性状的综述及其摄取和易位的见解

邻苯二甲酸酯是合成化合物,主要用作各种塑料和聚合物的增塑剂,以改善其物理性能。由于与聚合物基质存在物理结合,它们被报告为环境不同领域中无处不在的污染物。在包括人类在内的动物中,已知它们会引起各种毒性作用。然而,植物中邻苯二甲酸酯引起的应激较少受到关注,因为植物同样容易受到暴露,因为它们是不动的,并且是环境的重要组成部分,不容忽视。此外,由于它们在全球农业土壤中经常被检测到,因此在过去十年中,人们对邻苯二甲酸酯引起的植物胁迫引起了极大的关注。农业土壤中邻苯二甲酸酯的主要来源是地膜覆盖、废水灌溉、农药喷洒、使用生物固体改善土壤性质等。从土壤中,邻苯二甲酸酯主要通过根进入植物体内,并在不同营养阶段进行生物放大。生态系统中的水平。因此,邻苯二甲酸盐被宣布为内分泌干扰物,它们在可食用植物中的积累引起了粮食安全问题。此外,观察到植物中邻苯二甲酸酯的积累会影响萌发、生长和发育,并据报道会干扰植物的正常代谢,导致色素、渗透物、胁迫生物标志物的含量和抗氧化酶的活性发生调节,从而减少食用植物的产量和质量。农药喷洒、使用生物固体改善土壤性质等。邻苯二甲酸盐可以从土壤中主要通过根进入植物,并在生态系统中的不同营养水平上进行生物放大。因此,邻苯二甲酸盐被宣布为内分泌干扰物,它们在可食用植物中的积累引起了粮食安全问题。此外,观察到植物中邻苯二甲酸酯的积累会影响萌发、生长和发育,并据报道会干扰植物的正常代谢,导致色素、渗透物、胁迫生物标志物的含量和抗氧化酶的活性发生调节,从而减少食用植物的产量和质量。农药喷洒、使用生物固体改善土壤性质等。邻苯二甲酸盐可以从土壤中主要通过根进入植物,并在生态系统中的不同营养水平上进行生物放大。因此,邻苯二甲酸盐被宣布为内分泌干扰物,它们在可食用植物中的积累引起了粮食安全问题。此外,观察到植物中邻苯二甲酸酯的积累会影响萌发、生长和发育,并据报道会干扰植物的正常代谢,导致色素、渗透物、胁迫生物标志物的含量和抗氧化酶的活性发生调节,从而减少食用植物的产量和质量。邻苯二甲酸盐主要通过根进入植物体内,并在生态系统中的不同营养水平上进行生物放大。因此,邻苯二甲酸盐被宣布为内分泌干扰物,它们在可食用植物中的积累引起了粮食安全问题。此外,观察到植物中邻苯二甲酸酯的积累会影响萌发、生长和发育,并据报道会干扰植物的正常代谢,导致色素、渗透物、胁迫生物标志物的含量和抗氧化酶的活性发生调节,从而减少食用植物的产量和质量。邻苯二甲酸盐主要通过根进入植物体内,并在生态系统中的不同营养水平上进行生物放大。因此,邻苯二甲酸盐被宣布为内分泌干扰物,它们在可食用植物中的积累引起了粮食安全问题。此外,观察到植物中邻苯二甲酸酯的积累会影响萌发、生长和发育,并据报道会干扰植物的正常代谢,导致色素、渗透物、胁迫生物标志物的含量和抗氧化酶的活性发生调节,从而减少食用植物的产量和质量。
