%X To evaluate the environmental safety of the joint action of nano-TiO2 and metal Cd, M. aeruginosa was used as the model organism to investigate the effect of different concentrations of nano-TiO2 and nano-TiO2 with the heavy metal Cd on algae photosynthesis in the aquatic environment. Nano-TiO2 can promote the growth of algae at low concentrations (0~50 mg·L-1), while the algae cells growth rate was inhibited when the concentrations of nano-TiO2 were greater than 50 mg·L-1 in a pattern of dosage effect. As the presence of nano-TiO2 and Cd ions, the toxicity of ions was reduced significantly because of the adsorption of Cd ions on nano-TiO2 . Therefore, the ecological toxicity and environmental effects of nano-TiO2 should not be neglected. The biological effects of nanomaterials combined with other environmental pollutants should be considered.
