Cobalt nanoparticles (CoNPs) are being used in wide range of applications and may enter aquatic environments where they pose a potential threat to aquatic organisms. Algal growth inhibition tests were conducted to explore the potential toxicity of CoNPs on marine microalgae, Platymonas subcordiforus, Chaetoceros curvisetus and Skeletonema costatum. This is one of the first time to explore toxicity of CoNPs on marine algae systematically. The results showed that CoNPs induced toxicity on the three algae. The CoNP toxicity on three species microalgae was partly attributed to the Co(2+)released by CoNPs in the f/2 seawater medium. The particle size distribution of CoNPs in seawater revealed that CoNPs were agglomerated in the seawater. The shading effect of CoNPs and scanning electron microscope (SEM) images also showed the aggregating of CoNPs and microalgae, which influenced the photosynthetic utilization and inhibited the growth of the three algae. The order of toxic sensitivity of CoNPs on the three algae was as follows: Platymonas subcordiforus < Chaetoceros curvisetus < Skeletonema costatum. (C) 2018 Elsevier Ltd. All rights reserved.
