Figure 1From: Transformation of PVP coated silver nanoparticles in a simulated wastewater treatment process and the effect on microbial communitiesSilver concentrations in the effluent and the total mass of Ag added to the AgNP dosed (a); Ag+dosed (b); and, control (c) SBRs. Less than 1% of added Ag was found in the effluent. Nominal Ag concentrations were calculated from measured Ag spiking solution concentrations. Error bars represent one standard deviation (n = 3).Back to article page
