To test impact of commercial nanomaterials on environment and human health, the potential eco-toxicity of nanosized silver powder was investigated with bacteria, which contains Gram-negative Escherichia coli and Gram-positive Bacillus subtilis, and yeast strain. Commercial product of silver nanopowder prepared in water contains both silver nanoparticles (AgNPs) and silver ions. AgNPs and Ag ion contents were measured by ICP (Inductively Coupled Plasma) and ISE (Ion Selective Electrodes). Toxic effects to cell after direct exposal with silver powder solution were confirmed by counting colony forming units (CFU) on agar plates and by images of transmission electron microscope (TEM).
