Abstract

Toxicity and interference effects of dibutyl phthalate (DBP) on the growth of Pavlova viridis were studied. The exposureconcentrations of DBP were 0, 2.5, 3.0, 3.5, 4.0, 5.0, 7.5 mgÃ‚Â·L-1. The cell density, photosynthetic pigment content, chlorophyllfluorescence characteristics and malondialdehyde (MDA) content were examined. The results showed that DBP inhibited the growth of P.viridis, and the cells were completely killed at the high concentrations (5 and 7.5 mgÃ‚Â·L-1). The contents of chlorophyll a and carotenoidssignificantly decreased with the increase of DBP concentrations. Photochemical efficiency of PSII (Fv/Fm), potential activity of PSII(Fv/Fo), actual photochemical efficiency of PSII in the light (Yield) and the electron transport rate (ETR) significantly decreased withincreasing concentrations of DBP, while the content of MDA increased. The results confirm that the DBP has toxic effects on thepopulation of the microalgae.
