From: Interaction of silver nanoparticles with algae and fish cells: a side by side comparison
EC50 values of AgNP and AgNO3 in algae and fish cell exposures as a function of total silver. Times of exposure were selected based on the response of the respective cell type, with algal cells responding quickly with no further change in EC50 after 1 h whereas EC50 further decreased for fish cells over a 24 h period. Data presented as mean ± SD; n = 3. The error bars are smaller than the symbols due to the exponential scale in Y-axis
