Graphene oxide interaction with Lemna minor: Root barrier strong enough to prevent nanoblade-morphology-induced toxicity

Original language description

The production of graphene oxide (GO) along with its applications in various aquatic 20 environments is vastly increasing thanks to its rapidly expanding range of new GO-based 21 environmental technologies. Therefore, the fate of GO in aquatic environments is an important 22 issue, as it could become an environmental challenge if its potential toxic mechanism is not 23 addressed properly. Number of studies reporting the toxicity of GO to various aquatic 24 organisms is still increasing. However, research data on the possible toxic mechanism of GO 25 towards aquatic plants have yet to be collected, especially regarding GO’s surface chemistry. 26 Here, we studied the interaction of three differently oxidized GO systems with model aquatic 27 plant Lemna minor. We found that although none of the three GOs caused lethal phytotoxicity 28 to Lemna after 7 days, the mechanism of action was dependent on the GO’s surface oxidation. 29 Based on the amount of functional surface groups, the GO was able to directly interact with the 30 Lemna’s root through its edges. However, in this case in contrast to algae and crustaceans, the 31 interaction did not lead to a mechanical damage. Therefore, our results showed that GO is not 32 hazardous to Lemna minor even at very high concentrations (up to 25 mg/L), because the root 33 barrier proved to be strong enough to prevent GO’s penetration and its consequent toxicity.
