“…This technique is plant-based, such as plants that grow in nature as well as plants that have been genetically engineered to heal land : polluted soil and water [14]. The plant to phytoremediation technologies have the capacity to take significant quantities of heavy metals into their roots [15], withstand various metals, and have physiological characteristics to adapt to varied settings [16]. In addition, the metal detoxification phytoremediation technique for wastewater treatment is more cost-effective and ecologically benign [17].…”

Phytoremediation utilizes metal-trapping plants to recover water as the main source of contamination, Pistia Stratiotes L. is a hyperaccumulator plant that is considered capable of reducing hexavalent chromium levels in wastewater. This is evidenced by the results obtained on each of the variables investigated, namely the effect of contact time and the number of plants. Where, the effect of contact time on the most optimal reduction in hexavalent chromium concentration on day 10 is 22.55 mg/ L with an efficiency value of 54.89 %. While the effect of the number of plants on the reduction in the most optimal metal concentration was found in the first reactor with the number of plants 4, chromium concentration was 23.16 mg/ L with an efficiency value of 54.89%. This means that the longer the phytoremediation process will affect the decrease in chromium levels in waste samples but has no effect on the number of plants used if the plant mass is not calculated before treatment. The recommended kinetic models for phytoremediation systems using P. Stratiotes L plants are Richard's Pseudo First Order and Pseudo Second Order. However, when viewed from the prediction value and experimental data, Pseudo Second Order Kinetic Models are considered suitable to describe the phenomenon that occurs in this study, with an SSE value of 1.0042 and a reaction rate constant of 1.1662 day-1 to 1.5623 day-1.

“…Due to growing industrialization and urbanization, the content of HMs in the environment has increased significantly over the past few decades, which has caused serious concern worldwide (Suman et al, 2018). HMs are a group of metal elements with a density greater than 5 g/cm 3 and an atomic mass exceeding the mass of calcium (MW = 40) (Prieto et al, 2018). Most HMs are extremely toxic.…”

One of the most serious problems worldwide is heavy metal (HM) pollution. HMs can have a toxic effect on human health and thus cause serious diseases. To date, several methods have been used to clean environments contaminated by HMs, but most of them are expensive, and it is difficult to achieve the desired result. Phytoremediation is currently an effective and affordable processing solution used to clean and remove HMs from the environment. This review article discusses in detail the technology of phytoremediation and mechanisms of HM absorption. In addition, methods are described using genetic engineering of various plants to enhance the resistance and accumulation of HMs. Thus, phytoremediation technology can become an additional aid to traditional methods of purification.

“…On the other hand, heavy metals such as Cd, Pb, arsenic (As), and Hg are metals that can not have a biological function on living organisms. These heavy metals, whether necessary or not, may become toxic when they are taken in excessive amounts by living organisms, may adversely affect the growth and reproduction of organisms, and even cause their death (Prieto et al, 2018). As these pollutants cannot be biodegradable, they are a serious concern for living organisms and the environment as carcinogenic and mutagenic compounds (Wu et al, 2018).…”

Aim of study: The aim of this study was to determine the phytoremediation capacity of sunflower (Helianthus annuus L.), which can also be used as a bioenergy plant, in soils contaminated with copper (Cu), zinc (Zn) and lead (Pb) from the waste dumping sites during the mining operations. Area of study: Phytoremediation study was carried out in Artvin Coruh University Research greenhouse environment. Material and Methods: Plants were grown by mixing clean and contaminated soil at the rates of 0%, 50% and 100%. Bioaccumulation (BAF) and translocation (TF) factors were calculated by measuring heavy metal concentrations in soil and plant samples. The bioaccumulation factor is calculated by dividing the metal concentration in the shoots with the metal concentration in the soil. The translocation factor expresses the ratio of the metal concentration in the plant green parts to the root metal concentration. Main results: The sunflower plant has accumulated the highest Zn in the shoots, while Cu and Pb have accumulated the highest in the roots. The mean BAF values of the plants were determined as 0.72 for Zn, 0.5 for Pb and 0.28 for Cu, while the mean TF values were determined as 1.25 for Zn, 0.97 for Pb and 0.52 for Cu. Highlights: The findings show that the sunflower plant can be used in the phytostabilization of Cu metal and in the phytoextraction of Zn and Pb metal to reclaim heavy metal contaminated soils.
