مستخلص: | The use of copper (Cu) in numerous industrial and agronomic activities has led to an increase in the contamination of water bodies. Copper removal from contaminated water can be accomplished through phytoremediation using Pistia stratiotes, which is a simple, effective, and affordable approach. The present work evaluates the ability of Pistia stratiotesto extract copper from contaminated water, a source of water that naturally contains plant nutrients. The control was devoid of Cu and experimental sets were set up with contaminated water (artificially contaminated) spiked with 0.5, 1.5, 15, and 150 mg/L of Cu and both sets containing P. stratiotes. Our study demonstrated the ability of P. stratiotesto extract Cu from contaminated water and suggested that it may also be able to phytoremediate higher levels of metal contamination. The highest removal of Cu was at 1.5-mg/L treatment. The effectiveness of phytoremediation was measured based on the plant’s bioaccumulation factor (BCF; 35.1) and translocation factor (TF; 6.9). Cu exposure caused a considerable decrease in the amount of chlorophyll contents in leaves from standard total chlorophyll 300 to 0.25 µg/mL because it inhibited the biosynthesis of photosynthetic pigment in leaves. According to thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) study, the contaminated water content tends to decline when the exogenous Cu supply increases and exhibited different types of decompositions. In contrast to control plants, the data revealed that Cu-stressed plants displayed a distinct type of weight loss. The observed variations related to reshaping processes brought on by Cu stress at the level of the cell wall, which had an impact on water distribution and plants interactions. |
