Determination of relative rates of release of Ag+ by long (L) and short (S) AgNWs at a silver concentration of 111 μM in water and in Daphnia media. Silver was undetectable for S-PVP-NW in COMBO and water and for all L-NW samples. Ag+ was defined as the fraction passing through a 0.2-μm filter. The main source of error is Ag+ retention in the filter. To represent the magnitude of this uncertainty, the plot contains error bars that are the standard deviations on individual measurements of the second, third and fourth 1-mL portions of the filtrate passed through the same filter.
