    <description descriptionType="Abstract">&lt;p&gt;This study focused on developing surrogate indicators for predicting oxidation of phenolic groups in dissolved organic matter (DOM), suppression of halophenols&amp;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&lt;sub&gt;3&lt;/sub&gt; preferentially reacts with the DOM phenolic moieties and less so with the aromatic carboxylic groups with increasing O&lt;sub&gt;3&lt;/sub&gt;/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&lt;sub&gt;3&lt;/sub&gt; doses or changes of UV absorbance until it reached 85% suppression of the halophenols&amp;rsquo; formation from unaltered DOM. The thresholds of decreases of UVA254, UVA280 and humic-like fluorescence corresponding to 85% suppression of halophenols&amp;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, &amp;le;26.5% for SR_NOM and &amp;le;31.5% for Yangtze River at applied O&lt;sub&gt;3&lt;/sub&gt; doses. Measurement of changes of estrogenic activity during ozonation of water and wastewater showed that to attain a &amp;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 &amp;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.&lt;/p&gt;</description>
