The August 2008 issue of Environmental Health Perspectives includes an article entitled “Nano-Food Chain Link Examined,” which reports on recent research by the U.S. National Institute of Standards and Technology (NIST) regarding whether nanomaterials biomagnify in the food chain. NIST reports that certain nanomaterials may not accumulate in the food chain, but notes that additional research is necessary before any generalizations can be made regarding environmental and human safety of nanomaterials.
