Association between low-concentration PM2.5 exposure and emergency department visits for cardiovascular diseases: a time-series study
We propose that this complex pattern reflects a balance between adaptive hormetic responses at low exposures, toxic effects at moderate levels, and behavioral adaptations during high pollution episodes. These findings underscore that maintaining PM₂.₅ concentrations within a moderate range may yield greater public health benefits in low-pollution regions like Haikou, offering critical guidance for refining air quality standards and preventive interventions.
