Most relevant sources and emission pathways of pollution for selected pharmaceuticals in a catchment area based on substance flow analysis

Study on Pharmaceuticals Removal by Activated Sludge Treatment

“…The pollutants were selected due to their relative high use by humans [7][8][9], concentrations of approximately 0.13 μg/L of Permethrin and 1 μg/L of Atenolol were detected in municipal wastewater [10,11]. Permethrin is a chemical classified in the pyrethroid insecticide group and is also used as a medication in the form of cream or lotion [11,12].…”

Fate of nutrients and trace contaminants in a large shallow soda lake. Spatial gradients and underlying processes from the tributary river to the reed belt

“…In the same period of time, other monitoring campaigns analyzed these contaminants in the Wulka river before its inow in the reed belt estuary. [32][33][34][35] With exception of total metals, which are likely partially deposited with suspended sediments in this area, for these contaminants no alteration is expected to occur within the reed belt estuary. Therefore, such measurements (Tables A4 and A5 †) were included in this study to better assess the input via the river.…”

Environmental concentrations of the antidiabetic Metformin cause liver damage in Astyanax lacustris (Lütken, 1875) individuals after chronic exposure

“…Even in nontherapeutic doses, these compounds can still interfere with the environment and human health (Daughton and Ruhoy, 2008). In general, these studies range from evaluating the concentration of medications in the environment to removal alternatives, which often involve the use of bioreactors (Ghirardini et al, 2021;Goswami et al, 2018;Scheurer et al, 2012) aiming to minimize the damages caused by these pollutants (Vatovec;Wagoner;Evans, 2017).…”

“…Wastewater treatment plants have been the focus of studies regarding introducing pollutants, such as pharmaceutically active compounds, into the environment (Ghirardini et al 2021). Even in nontherapeutic doses, these compounds can still interfere with the environment and human health (Daughton and Ruhoy, 2008).…”
