“…The correlation between triclosan and the sum of all biocides can be set almost equal to the correlation of triclosan to the concentration of triclocarban in the sediment phase (Table 1); hence, other substances hardly contribute to the sum of the biocides. In addition, Wick et al, 2010;Yoon et al, 2010;Zhao et al, 2010Zhao et al, , 2013. This suggests that triclosan could be a reliable chemical indicator for predicting the levels of household biocides in surface water and sediment.…”

“…Removal of these contaminants should be achieved in conventional wastewater treatment plants, mainly through biological oxidation, but these systems are not specifically designed for this role. In fact, as rule of thumb, emerging contaminants pass unaffected in a great extent through the classical unit operations of wastewater treatment plants [8][9][10][11]. However, because of their persistent and potentially hazardous character, these compounds may negatively affect living organisms in the aquatic environment and, consequently, more advanced treatments are needed to complete their removal from wastewater.…”

Removal of nine pharmaceutical compounds: acetaminophen, AAF, antipyrine, ANT, caffeine, CAF, carbamazepine, CRB, diclofenac, DCF, hydrochlorothiazide, HCT, ketorolac, KET, metoprolol, MET and sulfamethoxazole, SMX, spiked in a primary sedimentation effluent of a municipal wastewater has been studied with sequential aerobic biological and ozone advanced oxidation systems. Ozone, UVA or Fe(III) during photocatalytic ozonations also allowed mineralization increases, compared to the single ozonation process, from 13% to about 35%. Biodegradability of the treated wastewater increased 50% in the biological process and other 150% after the ozonation processes. Both untreated and treated wastewater was non toxic for Daphnia Magna except when Fe(III) was used in photocatalytic ozonation. In this case, the ferryoxalate formed seems to be the reason of toxicity. Kinetic information on ozone processes reveals that pharmaceuticals at the very low concentrations they are found in urban wastewater are mainly removed through free radical oxidation.2

“…Those chemicals are commonly used in household and industrial products and can enter the environment through municipal and industrial wastewater discharges, agricultural runoff, solid-waste leaching, and garbage incineration (Campbell et al 2006;Kawagoshi et al 2003;Sidhu et al 2005). The occurrence of EDCs in the environment has been reported worldwide (Gong et al 2009;Mayer et al 2007;Pojana et al 2007;Yoon et al 2010), and increasing evidences have suggested possible adverse effects of EDCs to aquatic organisms even at environmentally relevant concentrations (Bahamonde et al 2014;Vajda et al 2011;Woodling et al 2006).…”

Occurrence of five endocrine-disrupting chemicals (EDCs)-bisphenol-A (BPA), triclosan (TCS), 17a-ethinyl estradiol (EE2), benzophenone-3, and 4-methylbenzylidene camphor-were monitored in East Lake, the largest urban lake in China. Other than EE2, all selected EDCs were detected at least once in the lake water with concentrations B89.1 ng/L. EDCs were detected with greater occurrence in spring than in other seasons. In lake sediment, TCS was detected at the greatest concentration (30.9 ng g -1 ), whereas BPA and EE2 were not detected. Spatial distribution of the EDCs in the lake water and the lake sediment showed similar patterns, and greater EDC residuals were found from those sites with known wastewater input. The linear adsorption coefficients (K d ) varied from 17.9 to 1,017 L kg -1 and were related to the octanolwater partition coefficient (K ow ) values of the compounds. Photodegradation was a major process removing the EDCs from the lake water, and the presence of dissolved organic material and NO 3 -in the lake water can accelerate the photodegradation process. Degradation of the EDCs in the lake sediment was relatively slow and occurred mainly due to the microbial processes. All compounds were found more persistent under anoxic conditions than under oxic conditions.
