Abstract

Phytoremediation is green technology based on the application of plants to remediate contaminated media. This paper reviews five species of local plants used for phytoremediation in Thailand: Pteris vittata L., Pityrogramma calomelanos L., Chrysopogon zizanioides L., Eichhornia crassipes (Mart.) Solms, and Pistia stratiotes L. For each plant, its pollutant removal efficiency and mechanism is reviewed. The main mechanisms of phytoremediation, such as phytoextraction, rhizofiltration, phytostabilization, phytodegradation, rhizodegradation, and phyto-volatilization, are concisely described. Screening local plants for phytoremediation is a cost-effective and easy to manage approach to derive suitable plants that are resistant to harmful environmental conditions. To be suitable, plants should have a fast growth rate, produce a large biomass yield, have a high tolerance to the toxic effects of the pollutants, and have a good capacity for pollutant uptake. Moreover, applying the proper species for each contaminant enhances the removal efficiency and supports sustainable phytoremediation.

本地物种在植物可持续修复中的应用

植物修复是一种以植物修复污染介质为基础的绿色技术。本文综述了泰国五种用于植物修复的本地植物:Pteris vittata L.， Pityrogramma calomelanos L.， Chrysopogon zizanioides L.， Eichhornia crassipes (Mart.)。对不同植物的污染物去除效率和机理进行了综述。简要介绍了植物修复的主要机制，如植物提取、根际过滤、植物稳定、植物降解、根际降解和植物挥发。筛选当地植物进行植物修复是一种成本效益高且易于管理的方法，可以获得对有害环境条件具有抗性的合适植物。适合的条件是植物生长速度快，生物量产量大，对污染物的毒性作用具有较高的耐受性，并具有良好的污染物吸收能力。此外，对每种污染物采用适当的物种可以提高去除效率，并支持可持续的植物修复。

期刊介绍： The Environment and Natural Resources Journal is a peer-reviewed journal, which provides insight scientific knowledge into the diverse dimensions of integrated environmental and natural resource management. The journal aims to provide a platform for exchange and distribution of the knowledge and cutting-edge research in the fields of environmental science and natural resource management to academicians, scientists and researchers. The journal accepts a varied array of manuscripts on all aspects of environmental science and natural resource management. The journal scope covers the integration of multidisciplinary sciences for prevention, control, treatment, environmental clean-up and restoration. The study of the existing or emerging problems of environment and natural resources in the region of Southeast Asia and the creation of novel knowledge and/or recommendations of mitigation measures for sustainable development policies are emphasized. The subject areas are diverse, but specific topics of interest include: -Biodiversity -Climate change -Detection and monitoring of polluted sources e.g., industry, mining -Disaster e.g., forest fire, flooding, earthquake, tsunami, or tidal wave -Ecological/Environmental modelling -Emerging contaminants/hazardous wastes investigation and remediation -Environmental dynamics e.g., coastal erosion, sea level rise -Environmental assessment tools, policy and management e.g., GIS, remote sensing, Environmental -Management System (EMS) -Environmental pollution and other novel solutions to pollution -Remediation technology of contaminated environments -Transboundary pollution -Waste and wastewater treatments and disposal technology
