“…Heeb et al, 2012) Yang et al, 2013). Caffeine is removed efficiently by WWTPs (more than 85%) and can be degraded in the natural environment (Buerge et al, 2003;Sui et al, 2010). Therefore, caffeine can be used as a molecular tracer for the efficiency of WWTPs (Buerge et al, 2003;Standley et al, 2000).…”

• The Yangtze River drains 40% of China's mainland with 400 million inhabitants • Monthly concentrations and annual loads of organic pollutants were determined • Seasonality of loads of PAHs, most pesticides, and antiinfectives were concise • In spite of low concentrations due to high water discharge, pollutant loads are considerable a b s t r a c t a r t i c l e i n f o Twenty percent of the water run-off from China's land surface drains into the Yangtze River and carries the sewage of approximately 400 million people out to sea. The lower stretch of the Yangtze therefore offers the opportunity to assess the pollutant discharge of a huge population. To establish a comprehensive assessment of micropollutants, river water samples were collected monthly from May 2009 to June 2010 along a crosssection at the lowermost hydrological station of the Yangtze River not influenced by the tide (Datong Station, Anhui province). Following a prescreening of 268 target compounds, we examined the occurrence, seasonal variation, and annual loads of 117 organic micropollutants, including 51 pesticides, 43 pharmaceuticals, 7 household and industrial chemicals, and 16 polycyclic aromatic hydrocarbons (PAHs). During the 14-month study, the maximum concentrations of particulate PAHs (1-5 μg/g), pesticides (11-284 ng/L), pharmaceuticals (5-224 ng/L), and household and industrial chemicals (4-430 ng/L) were generally lower than in other Chinese rivers due to the dilution caused of the Yangtze River's average water discharge of approximately 30,000 m 3 /s. The loads of most pesticides, anti-infectives, and PAHs were higher in the wet season compared to the dry season, which was attributed to the increased agricultural application of chemicals in the summer, an elevated water discharge through the sewer systems and wastewater treatment plants (WWTP) as a result of high hydraulic loads and the related lower treatment efficiency, and seasonally increased deposition from the atmosphere and runoff from the catchment. The estimated annual load of PAHs in the river accounted for some 4% of the total emission of PAHs in the whole Yangtze Basin. Furthermore, by using sucralose as a tracer for domestic wastewater, we estimate a daily disposal of approximately 47 million m 3 of sewage into the river, corresponding to 1.8% of its average hydraulic load. In summary, the annual amounts flushed by the Yangtze River into the East China Sea were 2.9 × 10 6 tons of dissolved and particulate organic carbon (DOC and POC), 369 tons of PAHs, 98 tons of pesticides, 152 tons of pharmaceuticals, and 273 tons of household and industrial chemicals. While the concentrations seem comparably moderate, the pollutant loads are considerable and pose an increasing burden to the health of the marine coastal ecosystem.

“…Now days the presence of pharmaceuticals and their metabolites in urban wastewater, mainly as a consequence of the uptake of medicines, is largely known [1][2][3][4][5]. Because of the presence of active biochemical principles in their molecules, pharmaceuticals, once released to water environments, present potential hazardous effects on humans and aquatic ecosystems [6,7].…”

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
