Letter to the editor
The above review has received wide attention since it was summarised in the July 2016 edition of the European Commission’s ‘Science for Environment Policy’. Such reviews are incredibly helpful to the wider scientific and practitioner community in distilling and evaluating relevant literature. However, given the currently contested status of engineered nanoparticles in the field of polluted groundwater remediation, the conclusions and headline message from the paper would have benefitted from a more nuanced terminology in the conclusions that more obviously emerged from the literature.
One of the contentions in this paper is that the use of nanoremediation is potentially problematic for soil functions. This assertion is made in part based on a limited set of publications about impacts of nano zero valent iron (nZVI) on denitrifiers, which the authors then extend to signify the entire nitrogen cycle. This assertion is flawed for a number of reasons. (1) nZVI use in...
