PUBLICATION: Microcosm study on nano zero-valent iron aging in soil

Songlin Wu et al. recently published a paper focused on different types of nanoscale zero-valent iron (nZVI) particles incubated in soils to investigate the nZVI aging and changes in microbial community compositions. Nano zero-valent iron is a promising material for remediating metal(loid)-contaminated soils, but its aging in the soil ecosystem and interaction with soil microbial communities have not been resolved. Complementary microspectroscopic analyses as well as DNA sequencing were employed in this study. The results revealed the transformation of nZVI into Fe (oxy)hydroxides regulated by different polymer coating types, and the bilateral interactions between nZVI aging and the microbial communities.
