Copper nanoparticles harm zebrafish

Abstract:
Researchers have found that nanosized copper particles affect fish gills through a different and as-yet-unknown mechanism than dissolved copper ions do. The results, published in ES&T ("Exposure to Copper Nanoparticles Causes Gill Injury and Acute Lethality in Zebrafish"), suggest that copper nanoparticles are more lethal than those composed of carbon or titanium dioxide (TiO2). Researchers not connected with the work caution that the study is just a first step in assessing the effects of copper and other metals at nano scales.
