Abstract

Red tide alga Phaeocystis globosa was exposed to nonylphenol concentrations of 0, 0.1, 0.2, 0.3, 0.4, 0.5 and 0.6 mg'L-1 for 96 h to explore the ecological toxic effects of nonylphenol on marine harmful microalgae. Cell density, protein content, photosynthetic pigment content, malondialdehyde content, and maximal photochemical efficiency of PSII (Fv/Fm) of P. globosa were examined. The results showed that the 96 h EC50 of nonylphenol for P. globosa was 0.42 mg'L-1. The growth, protein content, photosynthetic pigment content, and Fv/Fm decreased, whereas MDA content increased with the increase of nonylphenol concentration. The carotenoid content, protein content and Fv/Fm were higher in low concentration of nonylphenol (0.1 mg'L-1) than in the control, suggesting that nonylphenol induces hormesis on P. globosa.
