Abstract：The toxic effects were investigated on three green algae (Scenedesmus quadricauda, Chlorella vulgaris and Selenastrum capricornutum) for 10days by using nNiO suspensions in different concentrations (0, 60, 120, 180, 240, 300mg/L). The cell density, the contents of chlorophyll a, protein, malonyldialdehyde (MDA), the activities of superoxide dismutase (SOD) and catalase (CAT) were measured respectively. The results indicated that: The growth of three species were inhibited under the stress of nNiO, and showed obvious dose effect during the same period; Effects of lower nNiO concentrations (60~120mg/L) on tested algae revealed a process of “inhibition-promotion-inhibition”, which meant that the growth of these algae was accelerated only in a certain period; Toxic effects of nNiO on three species demonstrated that the chlorophyll a and protein contents were decreased, the content of MDA was increased, and the antioxidant activity was reduced; Selenastrum capricornutum had a higher tolerance for nNiO, while Scenedesmus quadricauda and Chlorella vulgaris were more sensitive to nNiO.
