Seasonal changes in the concentration of 21 pharmaceuticals in a wastewater treatment plant (WWTP) in České Budějovice were investigated over 12months. The target compounds were 10 antibiotics, 4 antidepressants, 3 psychiatric drugs, 2 antihistamines and 2 lipid regulators. 272 Wastewater samples (136 influents and 136 effluents) were collected from March 2011 to February 2012 and analyzed using two-dimensional...
In this study, the stability of 124 target analytes in influent and effluent wastewater samples during short-term (4°C) and long-term (−18°C) storage was assessed. The most common storage scenario was considered, in which samples were frozen immediately after sampling without any pre-treatment. During short-term storage more analytes remained stable (concentration during storage was in the range of...
