Chlorpyrifos, is one of the most widely used organophosphorus insecticides for
agricultural activities, and it is highly toxic to non-target organisms. This paper aims to
acquire the experimental data on the eco-toxicological effects of Chlorpyrifos and the data
can support the assessment of toxicity on the phytoplankton. The microalgae S. platensis
was employed to evaluate toxicity of Chlorpyrifos by means of measuring the specific
growth rate, generation time, percent growth inhibition, the pigment content of chlorophyll
a and carotenoid and the antioxidant enzyme super oxide dismutase. In this study, the
results showed that EC50 values was found to be 33.65 mg L-1
, indicating the Chlorpyrifos
had a relatively limited growth of algae during the acute toxicity experimental period. The
growth of the microalgae was significantly affected at 40mg L−1 of Chlorpyrifos, showing
growth inhibition after 72h of exposure. Biochemical properties, including carotenoid,
chlorophyll and antioxidant enzymes of C. vulgaris were influenced by Chlorpyrifos at
relatively high concentrations. Moreover, when algae were exposed to Chlorpyrifos, SOD
activity was significantly enhanced compared to control.
