AB  - Knowledge of the interaction between graphene-based materials and 
      low-molecular-weight organic acids (LOAs) is essential to understand fate and 
      effects of graphene-based materials in the aquatic environment, but this 
      interaction remains poorly elucidated. In this study, the effects of LOAs on the 
      physicochemical properties of graphene nanoplatelets (GNPs) in an aqueous medium 
      and on the GNP toxicity to algae were studied. The unicellular green alga 
      Scenedesmus obliquus was exposed to GNP suspensions in the presence of benzoic 
      acid or gallic acid at various concentrations. The GNPs had smaller hydrodynamic 
      sizes and the GNP suspensions were more stable and had higher or lower surface 
      zeta potentials in the presence of LOAs than when LOAs were not present. The 
      toxic effects in S. obliquus cultures incubated with GNP suspensions containing 
      LOAs were related to the LOA concentration, and the presence of LOAs caused three 
      effects: stimulation, alleviation, and synergistic inhibition. The intensities of 
      the effects mainly correlated with the LOA concentration, the extent of 
      agglomeration, and particle-induced oxidative stress. The results indicate that 
      the environmental fates and toxicities of GNPs are strongly affected by the 
      binding of GNPs to LOAs.
