“…Because Cu is an enzyme component in photosynthesis, this explains why these elements exhibited higher uptake efficiencies in the root at the beginning of the experiment than Fe [8]. Moreover, vetiver roots are known as high Cu accumulators compared to other metals [14]. Several uncontrollable elements affect the elimination including the root length of vetiver grass which can be considered to enhance the rate of heavy metal removal effectiveness in water.…”

Phytoremediation using Vetiver grass (VG) has been used in the past few decades all over the world, but the effectiveness of its uptake mechanism in water has less been discussed especially in mixed metal conditions. Hence, the focus of this research was to determine and evaluate the heavy metal removal effectiveness of two heavy metals, copper (Cu) and iron (Fe), based on vetiver grass uptake and toxicity. Three treatments of Fe and Cu mixture were chosen, and individual concentrations act as a control. The vetiver grass at a height of 10 cm and a root length of 25 cm for each treatment was used and harvested on days 0,1, 3, 6 and 7. The roots were randomly cut, oven-dried and used the digestion method to extract the Fe and Cu in the root. From the result, vetiver grass has better Fe and Cu uptake ability in the mixture treatment compared to the individual treatment. Fe uptake is increasing up to 25.3 % in the presence of Cu (mixture 1). Meanwhile, for Cu, mixture 3 is an ideal ratio to increase the Cu uptake by 14.5%. It shows that both Fe and Cu facilitated each other’s uptake in real wastewater conditions. There were also observed minimal toxicity signs such as necrosis throughout the experiment. The appearance of vetiver grass has changed in this experiment starting day 3 and remains yellowish. In conclusion, wastewater that contains a high concentration of Fe than Cu can promise the improvement of both Fe and Cu uptake by vetiver grass. This study benefits researchers that apply phytoremediation to remove heavy metals in wastewater by providing a guideline for Fe and Cu removal by vetiver grass. In future, the study will focus on the mechanism and interaction of Fe and Cu uptake by root

“…In this study, the tolerance of vetiver grass at phytoremediation of boron polluted soil was examined. For this purpose, to determine the tolerance of the vetiver plant to boron, B from H3BO3 was applied to the soil at concentrations of 0,10,20, 40, 60, 80, 100, 200, 300, 400 mg B/kg. The results showed that the increase in boron concentration applied to the soil negatively affected plant growth and significant losses in plant height and weight and no growth was observed in plants above 40 mg/kg boron concentration.…”

Soil pollution is a significant environmental issue with various causes and consequences. Many industrialized and non-industrialized countries are faced with economic and ecological problems due to toxic element contaminations in soil environments. Especially, soils contaminated with toxic metals pose a major environmental and human health problem that needs an effective and affordable technological solution. Phytoremediation is a process that uses plants to clean up contaminated soil, water, or air. It is an environmentally friendly and cost-effective method for mitigating pollution and is often used in situations where traditional cleanup methods are impractical or too expensive. Vetiver grass is a type of perennial grass native to India. It is widely cultivated for various purposes and has several valuable characteristics such as erosion control and soil improvement. In this study, the tolerance of vetiver grass at phytoremediation of boron polluted soil was examined. For this purpose, to determine the tolerance of the vetiver plant to boron, B from H3BO3 was applied to the soil at concentrations of 0, 10, 20, 40, 60, 80, 100, 200, 300, 400 mg B/kg. The results showed that the increase in boron concentration applied to the soil negatively affected plant growth and significant losses in plant height and weight and no growth was observed in plants above 40 mg/kg boron concentration.
