Figure 5. Percentage of free silver (Ag+) and silver complexes (AgL) smaller than the membrane pores (< 3 kDa) plotted against exposure time for AgCit dispersed in algae and Daphnia media at pH 6, 7, and 8 in the absence and presence of (A) the HSs from the Sorocabinha River and (B) EPSs from Raphidocelis subcapitata. AgPEG = 1 µg L-1, AgPEG = 1 µg L-1 + HS = 1 mg L-1,
