Toxicity of CuO Engineered Nanoparticles to Eichhornia crassipes

Abstract:

Nanomaterials are touching almost every aspect of modern life in recent years and attract the attention of scientists, becoming a hot research in a short time. The extensively use of engineered nanopaticles (ENPs) has increased the risk of ENPs entering into aquatic environments. This study outlines nanotoxicity on large aquatic plants which plays important role in aquatic system. A series of concentrations of copper oxide engineered nanoparticles (CuO ENPs) were used to test the nanotoxicity to aquatic plant Eichhornia crassipes. Results showed that inhibition of plant growth was significant after exposed to CuO ENPs at the concentration of 50 mg/L. the inhibition to the root lengh was obvious. The leaf epidermis was severely damaged. All the results showed that CuO ENPs had nanotoxicity to Eichhornia crassipes and the water system.
