Objective:
- Characterize the stability of carbon nanoparticles in NOM.
- Characterize the bioavailability of carbon nanoparticles to aquatic organisms.
- Characterize the bioavailability of gold nanoparticles to Daphnia magna.
- Characterize the uptake and food chain transport of gold nanoparticles.
Summary/Accomplishments (Outputs/Outcomes):
Figure 1. Dephnia magna dry weight (mg) after exposure to MWNT-NOM
suspension (NP;mg/L). Growth was inhibited at all exposure concentrations
greater than 0.125 mg/L (p<0.01;r2 = 0.574).
Figure 2. Ceriodaphnia dubia reproduction (% control) during exposure to
MWNT-NOM suspensions. Significant decreases were observed in all concentrations
greater than 0.25 mg/L. Capital letters denote statistical groupings (p>0.05).
Figure 3. Photograph of the flume setup used to expose periphyton to gold nanomaterials. Inset
shows a zoom of the notched dam retaining water in the channel.
Conclusions:
Regardless of community composition, periphyton communities exposed to AuNM in closed flume systems displayed elevated Au concentrations, most likely due to physical aggregation and settling of AuNM. Dietary exposure to contaminated periphyton led to elevated Au tissue concentrations in L. stagnalis while Au was not detected in H. Azteca tissues. Differences between L. stagnalis and H. Azteca body burden may be attributable to feeding mechanisms. These results suggest selective feeding by macroinvertebrates, NM settling, and NM aggregation are important when considering NM fate in the environment and their movement throughout the food chain.
