pH modulation of arsenic phytoextraction and nutrient uptake in water hyacinth (eichhornia crassipes (Mart.))

Arsenic contamination in water area poses significant threats to ecosystems as well as human health around the world. For reducing the rate of arsenic pollution, phytoremediation, which applies plant-based systems, could provide a long-term solution. A hyper-accumulating plant, water hyacinth (Eichhornia crassipes), which is known for its rapid growth and efficient nutrient uptake, has emerged as an attractive candidate for arsenic phytoextraction. However, the efficiency of arsenic removal by water hyacinth could be affected by a variety of environmental factors, including various ranges of pH in aquatic environments. This study investigates the effect of pH modulation on arsenic phytoextraction efficiency in water hyacinth. Controlled laboratory experiments are conducted that to scrutinize the uptake and accumulation of arsenic in water hyacinth tissues under different pH conditions. The findings show that pH influences kinetics of arsenic uptake and physiological responses of plants. In the research, the optimal pH ranges were identified, which improved arsenic uptake by water hyacinth and maximized efficiency of phytoextraction. Furthermore, the complex correlation between pH levels and arsenic detoxification mechanisms in water hyacinth was emphasized. These scientific findings from this study have important implications for the design and implementation of phytoremediation strategies in arsenic-contaminated aquatic ecosystems. By elucidating the role of pH modulation in enhancing arsenic phytoextraction efficiency, this study advances sustainable environmental remediation practices and emphasizes the importance of taking environmental factors into account when optimizing phytoremediation processes.
