Abstract

The market for graphene-based products, such as graphene oxide (GO), is projected to reach nearly $675 million by 2020, hence it is expected that large quantities of graphene-based wastes will be generated by then. Wastewater treatment plants will be one of the ultimate repositories for these wastes. Efficient waste treatment relies heavily on the functions of diverse microbial communities. Therefore, systematic investigation of any potential toxic effects of GO in wastewater microbial communities is essential to determine the potential adverse effects and the fate of these nanomaterials in the environment. In the present study, we investigate the acute toxicity, i.e. short-term and high load, effect of GO on the microbial functions related to the biological wastewater treatment process. The results showed that toxic effects of GO on microbial communities were dose dependent, especially in concentrations between 50 and 300mg/L. Bacterial metabolic activity, bacterial viability, and biological removal of nutrients, such as organics, nitrogen and phosphorus, were significantly impacted by the presence of GO in the activated sludge. Furthermore, the presence of GO deteriorated the final effluent quality by increasing the water turbidity and reducing the sludge dewaterability. Microscopic techniques confirmed penetration and accumulation of GO inside the activated sludge floc matrix. Results demonstrated that the interaction of GO with wastewater produced significant amount of reactive oxygen species (ROS), which could be one of the responsible mechanisms for the toxic effect of GO.

Altmetric has tracked 3,712,057 articles across all sources so far. Compared to these this article has done well and is in the 85th percentile: it's in the top 25% of all articles ever tracked by Altmetric.
So far Altmetric has tracked 417 articles from this source. They typically receive a little less attention than average, with a mean score of 1.9. This article has done particularly well, scoring higher than 94% of its peers.
Older articles will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this score to the 95,096 tracked articles that were published within six weeks on either side of this one in any source. This article has done well, scoring higher than 82% of its contemporaries.
We're also able to compare this article to 21 articles from the same source and published within six weeks on either side of this one. This article has done particularly well, scoring higher than 90% of its contemporaries.
