Relationship between prevalence of odor annoyance at community level and NH3concentrations at air quality stations: measured (Figure2a)and from emission-dispersion modelling (Figure2b). Prevalence of odor annoyance is expressed as the proportion of respondents at each region that reports annoyance scores > 0 (odor annoyance at any degree) and annoyance scores > 1 (moderately, very or extremely annoyed by odor). Error bars indicate coefficients of variation of NH3 concentrations.
