Abstract

The present study investigated the effect of exposure to different concentrations of Glyphosate pesticide, cadmium and chromium elements in the polluted water medium on tolerance and the effectiveness of two algae Chlorococcum humicola and Chlorella vulgaris biomass by applying different concentrations (25, 50, 75, 100) mg/L −1 of pesticide, Cd and Cr (2.5, 7.5, 10, 12, 15, 20 and 25) (1, 2, 3, 4, 5) mg/L−1 respectively, with exposure time (3, 6, 9 and 12) days under laboratory conditions of the temperature of 25± 2°C, the intensity of light 3000 lux with 16 hours of light and 8 darkness and pH 7± 2 in static medium. The results showed that of the algae species used in the study was characterized by the ability to tolerate the Glyphosate pesticide concentrations of (25–100) mg/L−1 as well as the ability of the C.humicola to tolerate high concentrations of cadmium (2.5, 7.5, 10, 12.5, 15, 20, 25) mg/l−1 while the ability of C.vulgaris to tolerate concentrations less than cadmium (2.5, 7.5, 10, 12.5) mg/L−1 and the ability of the two algae to tolerate concentrations of chromium (1, 2, 3, 4, 5) mg/L−1.
