“…The photochemical degradation of OC is an important pathway for the removal of these compounds from the aquatic environment. 55,56 EfOM plays an important role as a photosensitizer by producing ROS, such as HO • , which is a very effective oxidant for the removal of organic compounds because of its non-selective reactivity with recalcitrant organic contaminants. 26,57 Although the characterization of the functional groups and basic chemical composition of the EfOM fractions was not included here, this study revealed that H 2 O 2 unrelated photoproduction of HO • differs depending upon the physicochemical properties of EfOM components, such as molecular size and hydrophobicity.…”

The photochemical formation of hydroxyl radical (HO(•)) from effluent organic matter (EfOM) depends upon the chemical properties of this heterogeneous mixture. In this study, two EfOM samples collected from wastewater treatment plants (WWTP A and B) were fractionated by both hydrophobicity (bulk and non-humic) and apparent molecular weight (AMW). The apparent quantum yield for HO(•) formation (ΦHO(•)) and the maximum fluorescence quantum yield (ΦF) were subsequently measured for each subfraction. The formation rates of HO(•) (considering only the hydrogen-peroxide-independent pathways) for the bulk waters were 4.8 × 10(-10) and 9.6 × 10(-11) M s(-1) for WWTP A and B, respectively. For the AMW fractions, the values of ΦHO(•) increased as the AMW of the material decreased. For the WWTP A sample, the ΦHO(•) increased from 2.54 × 10(-4) (bulk water) to 6.29 × 10(-4) for the <1 kDa fraction, and for the WWTP B sample, the value of ΦHO(•) increased from 6.50 × 10(-5) for bulk water to 3.45 × 10(-4) for the <1 kDa fraction. In the case of fluorescence, the values of ΦF ranged from 2.37 × 10(-4) (bulk water) to 3.48 × 10(-4) (<1 kDa fraction) for WWTP A and 3.19 × 10(-4) (bulk water) to 5.75 × 10(-4) (<1 kDa fraction) for WWTP B. There was a linear correlation between ΦHO(•) and ΦF, suggesting that different photophysical processes occur in the chemical components of the fractions. Understanding the formation of HO(•) from EfOM is essential for understanding wastewater-impacted aquatic systems because these results influence the photochemical degradation and mineralization of trace organic contaminants.

“…In order to reduce residual concentrations of PPCPs, various advance treatments have been studied by many research groups (Lee and Gunten, 2010;Rosal et al, 2010 and many others). However, high levels of PPCPs are still detected in wastewater effluent, surface waters, and drinking waters (Kim et al, 2007;Lee et al, 2012;Yoon et al, 2010;Benotti et al, 2009). Since those trace organic compounds have been detected even in treated drinking waters by Benotti et al (2009), control of micropollutants has been important especially in the wastewater treatment plant, the main source of the micropollutants in the aquatic environments.…”

Abstract. Since trace organic compounds such as pharmaceuticals in surface water have been a relevant threat to drinking water supplies, in this study removal of pharmaceuticals and transformation of pharmaceuticals into metabolites were investigated in the main source of micropollutants such as WWTPs and engineered constructed wetlands. Pharmaceuticals were effectively removed by different WWTP processes and wetlands. Pharmaceutical metabolites with relatively low log D value were resulted in the low removal efficiencies compared to parent compounds with relatively high log D value, indicating the stability of metabolites. And the constructed wetlands fed with wastewater effluent were encouraged to prevent direct release of micropollutants into surface waters. Among various pharmaceuticals, different transformation pattern of ibuprofen was observed with significant formation of 1-hydroxy-ibuprofen during biological treatment in WWTP, indicating preferential biotransformation of ibuprofen. Lastly, transformation of pharmaceuticals depending on their structural position was investigated in terms of electron density, and, the electron rich C 1 = C 2 bond of carbamazepine was revealed as an initial transformation position.
