The aim of the research was to analyze the cytogenotoxic effects of water samples taken from the biological wastewater treatment. Samples were taken from different stages of of wastewater treatment from the town of Odžak, and from the river Bosna and Sava. As a bioindicator, Allium cepa were used. The lowest value of the mitotic index was recorded at the entry into the purification system (1.9), and the largest on the fertilizer that represents the purification product (16.85). The number of chromosomal aberrations in the purification process decreased by 52.7%. The results indicate that biological wastewater treatment reduces its genotoxic and cytotoxic effects. Cilj istraživanja je bio analizirati citogenotoksični efekat uzoraka vode uzetih sa postrojenja za biološko prečišćavanje komunalnih otpadnih voda. Uzorci su uzeti iz različitih faza obrade sa prečistača vode grada Odžak, te iz rijeka Bosne i Save. Kao bioindikator korištene su lukovice Allium cepa. Najmanja vrijednost mitotičkog indeksa zabilježena je na ulazu u sistem prečišćavanja (1,9%), a najveća na đubrivu koje predstavlja nus-produkt prečišćavanja (16,85%). Broj hromosomskih aberacija se u procesu prečišćavanja smanjio za 52,7%. Rezultati ukazuju na zaključak da se biološkom obradom otpadne vode smanjuje njen genotoksični i citotoksični efekat.
