Aquatic plants Eichhornia crassipes and Hydrilla verticillata were studied to see how they absorb and respond to the chemical triclosan (TCS) in water. The plants absorbed TCS differently, with E. crassipes taking in more in its roots and H. verticillata in its leaves. As the TCS concentration increased, the plants' chlorophyll, protein, and antioxidant levels decreased. H. verticillata was more affected by TCS than E. crassipes, likely due to how they absorb the chemical and their growth patterns. The roots of the plants were more sensitive to TCS than the leaves. Overall, the study showed that different aquatic plants react differently to TCS, with H. verticillata being more sensitive to its toxic effects.
