Effects of two synthetic pyrethroids on Arthrospira platensis Gomont growth and antioxidant parameters

The transport of pesticides from application areas to other results in pesticide contamination and this sort has led unexpected environmental problems worldwide. It is important determine the responses phytoplanktonic organisms these chemicals for an understanding effects on aquatic ecosystems. In study, Arthrospira platensis Gomont cyanobacteria were exposed different concentrations cypermethrin (0-50 µg mL-1) deltamethrin (0-2 mL-1). Changes chlorophyll-a concentration, absorbance OD560, antioxidant parameters (SOD, APX, GR, MDA, H2O2, proline) determined under exposure. Our showed that there a decrease OD560 content proportionate increase levels. Superoxide dismutase enzyme activity decreased with Cyp Dlm A. cultures. Glutathione reductase also applications but did not change application. Ascorbate peroxidase increased treatments applications. Although malondialdehyde hydrogen peroxide contents applications, they Proline conclusion, more toxic than applied.
