Once again, here come the headlines, across both the trade and mainstream press, warning us that manufactured nanoparticles are a danger to our health and environment.
This time it’s that nanoparticles stunt soybean crop growth.
The warnings are based on research at the University of California Santa Barbara’s Bren School for Environmental Science & Management. The language of the research, however, falls somewhat short of making such unconditional claims.
Instead the research, which was published the Proceedings of the National Academy of Sciences (PNAS), claims to demonstrate “what could arise over the long term” if plants were grown in soil that had been contaminated with manufactured nanomaterials (MNMs), zinc oxide and cerium oxide.
Even the research that inspired the UC Santa Barbara team to put metal oxides in farming soil only suggested that MNMs “could” alter food crop quality and yield. Of course, if the researchers were to take ordinary household bleach from under the kitchen sink and pour it onto farming soil, they would surely conclude that it “could” alter the quality of the crop.
