(40-07) Presence of Pharmaceuticals in Wastewater in Poland. Miksch, Korneliusz1, Rychta, Urszula*,1, Wozniak, Ewa1, Kalka, Joanna1, 1 Silesian University of Technology, Gliwice, Poland ABSTRACT- The review of the present knowledge pertaining to the presence of pharmaceuticals in the environment in Poland comparing to the countries of the Western Europe has been made in the article. The pharmaceuticals used are introduced along with urine and faeces depending on their pharmacological properties, as the mixture of metabolites or in an unchanged form to a sewerage system and from a sewerage system to a wastewater treatment plant. They, however, are not completely removed in treatment processes and along with sewage they come into surface water, which subsequently leads to the accumulation of the above substances to environment. So far, in Poland, none of reaserch centers has dealt with the monitoring of the presence of medicines and their metabolites in environment. The quantity of compounds of medical origin can be evaluated solely on the basis of annual sales and consumed medicines. Data of the Drug Institute in Warsaw served for the assessment of selected medicines concentration in municipal sewage. In the selected group of compounds, the highest estimated concentration was recorded for Iopromide (7,18 ug/l), the lowest concentration was for Ethinylestradiol (0,004 ug/l). The calculations conducted imply that in municipal sewage in Poland, the selected pharmaceuticals can reach values lower than in Western European countries. An exception can be antibiotic - Sulfamethoxazole, an ingredient of a very popular medicine in Poland called "Biseptol", whose concentration was estimated at 4,66 ug/l. Key words: pharmaceuticals, municipal sewage , wastewater treatment, concentration of drugs |
