  "description": "<p>This study focused on developing surrogate indicators for predicting oxidation of phenolic groups in dissolved organic matter (DOM), suppression of halophenols&rsquo; formation potential and abatement of estrogenic activity during ozonation of water and wastewater. The evolution of pH-dependent differential absorbance spectra suggests that O<sub>3</sub> preferentially reacts with the DOM phenolic moieties and less so with the aromatic carboxylic groups with increasing O<sub>3</sub>/DOC ratios and changes of UV absorbance and fluorescence. When ozonation used as pretreatment, the formation of halophenols in subsequent chlorination decreased linearly with increasing O<sub>3</sub> doses or changes of UV absorbance until it reached 85% suppression of the halophenols&rsquo; formation from unaltered DOM. The thresholds of decreases of UVA254, UVA280 and humic-like fluorescence corresponding to 85% suppression of halophenols&rsquo; formation were in the range of 25%~30%, 30%~35% and 30%~45%, respectively. Pre-ozonation also showed a moderate suppression of haloacetic acids (HAAs) formation potentials, &le;26.5% for SR_NOM and &le;31.5% for Yangtze River at applied O<sub>3</sub> doses. Measurement of changes of estrogenic activity during ozonation of water and wastewater showed that to attain a &gt;90% abatement of estrogenic activity, the corresponding thresholds of decreases of UVA254, UVA280 and humic-like fluorescence were ~30%, ~40%, and ~70%, respectively. Bromate formation was also suppressed to below 10 &mu;g/L before these thresholds. This study suggests that optimal ozonation conditions and a balance between control of disinfection byproducts (halophenols, HAAs and bromate) and elimination of estrogenic activity can be reached based on online data.</p>",
