Phytoremediation as an Effective Remedy for Removing Trace Elements from Ecosystems

Area of Science:

• Environmental Science
• Ecology
• Biotechnology

Background:

• Soil pollution by trace elements (TEs) is a significant global environmental challenge.
• Conventional remediation methods are often limited in applicability and can be costly.
• Innovative, environmentally friendly techniques like phytoremediation are crucial for ecosystem restoration.

Purpose of the Study:

• To review basic research methods, their strengths, and weaknesses in phytoremediation.
• To explore the effects of microorganisms on trace element-resistant plants (metallophytes) and endophytes.
• To highlight novel applications and future perspectives of phytoremediation.

Main Methods:

• Literature review and synthesis of existing research on phytoremediation techniques.
• Analysis of the role of microorganisms in enhancing plant tolerance and accumulation of trace elements.
• Evaluation of supportive treatments including genetic engineering, sorbents, phytohormones, and nanoparticles.

Main Results:

• Bio-combined phytoremediation with microorganisms presents an economically viable and environmentally sound solution.
• "Green roofs" show potential for capturing metal-bearing dust and toxic compounds.
• Phytoremediation is effective on less contaminated soils, urban green spaces, and along traffic routes.

Conclusions:

• Phytoremediation, especially when enhanced by microorganisms and novel applications like green roofs, offers a promising approach to soil remediation.
• Further development requires increased funding and interdisciplinary research to optimize its global application.
• Supportive treatments and energy crops can significantly enhance the efficacy of phytoremediation.
