From viewpoint of environmental analysis in the whole world became popular in the latest years the question of drugs’ breakthrough to the component of environment. These contami-nants belong to the biological active compounds, with different physical-chemical and biolog-ical properties and evince great tendency to bioaccumulation. They penetrate to the environ-ment because of their increasing of usage and wrong techniques of liquidation. The most often use drugs are preparations against pain – analgetics, and from this category there are non-steroidal anti-inflammatory drugs. The frequent usage of this compounds relate to their easy accessibility. From this large group of compounds was chosen for monitoring: diclofenac, ibuprofen, ketoprofen, salicylic acid, naproxen and acetaminophen; because they include in favorite preparations. The monitoring matrix was the wastewater from two waste water treat-ment plants (WWTP). The sampling was performed in inflow and outflow because the com-paring of concentration of selected contaminants and discovering of efficiency of removing the polutants reliance on treatment technology. For extraction of selected contaminants was used solid phase extraction (SPE) and for determination was used capillary zone electrophore-sis (CZE) with diode array detection (DAD). There was identified and quantified all of se-lected analgetics in inflow and so in outflow of WWTP. That means, this polutants infuse into surface water and then into other components of environment.
