© 2016 Parlar Scientific Publications. All rights reserved. The wastewater from meat processing industry is an important source of organic pollution in natural water bodies. In order to enable the identification and determination of concentration levels of pollutants the adaptation of analytical methods is necessary. During the research GC-MS was selected as conventional method for screening analyses of organic compounds in complex environmental matrix of meat industry wastewater. Sample preparation methods have been tested, and different solvents have been used during extraction to obtain the optimal method for the specific wastewater load of lipophilic pollutants from meat processing industry. The research is oriented onto the adaptation of screening analysis method for wastewater of meat industry, presenting the list and groups of key pollutants to provide the selection of organic pollutant for environmental monitoring plan development, prioritisation processes and future target analyses. The optimal analytical procedure has shown to be liquid liquid extraction with DCM as solvent coupled with Kuderna Danish apparatus for preconcentration of samples. The detected and identified substances during the study, which can be found on NORMAN'S list of emerging substances, include industrial chemicals, personal care products, fragrances, wood preservatives and antifoaming agents. A significant number of detected compounds ((E)-2-Octenal, (E,E)-2,4-Decadienal, 2- Methoxyphenol, Dioctyl hexanedioate, 2,6- Dimetilphenyl isocyanate, 2,6-dimethoksy-4-(2- propenyl), Etilallylphthalate, 2-methoxy-4-(prop-1- en-1-yl)phenol, N-Docosanol and other) have one or more hazardous characteristics placing them in highrisk substances which should not be found in receiving water bodies.
