Constantly increasing rate of drugs’ consumption can be related with environmental abundance of drug substances and their degradation products. Unused and used drugs are often discharged into municipal wastewaters or landfills. Wastewater treatment plants are not able to remove the entire load of drugs. Especially those which occur occasionally or at very low concentrations. Therefore, a variety of pharmaceuticals occur in surface and drinking water sources. A chronic low-level exposure to drugs occurring in a water environment can cause: antibiotic resistance, allergic reactions (eg. Penicillin), cause carcinogenesis (oxytetracycline, furazolidone), nephropathy (gentamicin) and have a negative impact on the natural human intestinal microflora. Therefore, it is not an easy task to assess a common human health effects related with chronic exposure to low doses of active pharmaceutical substances. Nonetheless, such knowledge seems essential in order to undertake preventive actions that would substantially decrease the level of health risk.
