The aim of the study was to determine the toxic effects of organic pigments Alizarin Red S and Alizarin Complexone on zebra fish (Danio rerio). For short-term acute toxicity tests on zebra fish concentration of 150; 300 and 600 mg/L were chosen for both dyes. Toxic effect of dyes was observed even in the variant with 10 g/L of sodium chloride. Addition of sodium chloride increases the deposition of dyes in the bone structures of the fish. LC50 values were analyzed graphically by using probit analysis. There was no mortality during the acute toxicity test with Alizarin Red S even at the highest concentration. Toxicity value (72hLC50) for zebra fish with a combination of Alizarin Red S + 10 g/L of sodium chloride is 546.42 mg/L. Mortality for Alizarin Complexone was 100% in 24 hours at
concentrations of 300 and 600 mg/L, with concentrations of 150 mg/L there was no mortality. In Alizarin Complexone supplemented with 10 g/L of sodium chloride was 100% mortality at all
concentrations up to 72 hours.
