New article in Chemosphere: “Effect of ZnO nanoparticles on Zn, Cu, and Pb dissolution in a green bioretention system for urban stormwater remediation”

Check out our new article by Caldelas et al. (2022) about the environmental impact of zinc oxide nanoparticles, in partnership with the landscape engineering company Naturalea. Highlights:

• We developed a bioretention system that retained up to 73% zinc, 66% copper, and >99% lead.

• The zinc oxide nanoparticles increased lead solubility, leading to a loss of bioretention efficiency.

Carex vulpina grew more and retained more nutrients and metals than the other species.

• Plants made a small contribution to metal extraction from stormwater.
