Abstract

Emerging nanomaterials are of great concern to aquatic environment. The inhibitory effects of silver nanoparticles (Ag-NP) and titanium oxide nanoparticles (TiO₂-NP) on the growth of aquatic plant duckweed were evaluated. Lemna paucicostata was used as a test organism, and the test method was followed by the OECD test guideline 221. Ag-NP (50 nm) and TiO₂-NP (2-3 nm) inhibited the growth of Lemna in different manner and the EC50s were calculated as 13. 8 and 538. 5 ppm, respectively. The LOECs of Ag-NP and TiO₂-NP were calculated to be 1 and 125 ppm, respectively. The results showed that Ag-NP could cause growth inhibition of Lemna in low concentration range (≥1 ppm), but TiO₂-NP appeared toxic effect to the growth of Lemna in the concentration range of ≥250 ppm, which was over two orders higher than the previously reported concentration of TiO₂-NP determined in the aquatic environment.
