The underappreciated role of nonvolatile cations in aerosol ammonium-sulfate molar ratios

<p>Overprediction of fine-particle ammonium-sulfate molar ratios (<i>R</i>) by thermodynamic models is suggested as evidence for interactions with organic constituents that inhibit the equilibration of gas-phase ammonia with aerosol sulfate and questions the equilibrium assumpti...
