- •
Toxic effects of biocide chlorine on freshwater green algae Closterium ehrenbergii.
- •
Significant reduction in growth and pigment level of C. ehrenbergii exposed above 0.5 mg L−1 Cl2.
- •
Cl2 causes damage to the photosystem observed by chlorophyll autofluorescence.
- •
Significant increases of antioxidant enzymes activities (LPX, SOD, CAT and GSH) with increasing Cl2.
- •
Cl2 discharged in aquatic environments damages to C. ehrenbergii & other microalgae.
