英文摘要As emerging contaminants, benzotriazole ultraviolet stabilizers (BUVSs) have been frequently detected in aquatic environments, which usually co-occur with heavy metals and cause complex toxicity to aquatic organisms. However, the specific role of BUVSs in the combined toxicity remains poorly understood. Herein, a harmful marine dinoflagellate Akashiwo sanguinea was used to explore the individual and combined toxicities of UV-234 and cadmium (Cd2+). Exposure to UV-234 at an environmental concentration (10 mu g L-1) slightly inhibited algal growth (P > 0.05). Individual exposure to both low (1.77 mg L-1) and high (5.30 mg L-1) concentrations of Cd2+ significantly impaired algal photosynthesis by altering photosynthetic pigments, disrupting energy absorption, dissipation and trapping, reaction center activation, and electron transport, thereby inducing oxidative stress, and up-regulated pyruvate metabolism and the tricarboxylic acid cycle. Notably, co-exposure with UV-234 mitigated the toxic effects induced by Cd2+, and caused weaker inhibition of algal growth via inducing less substantial oxidative damage. These findings highlight the significant influence of UV-234 and Cd2+ co-exposure on marine dinoflagellates, providing new insights into the joint toxicity mechanisms and a scientific basis for environmental risk assessment of emerging BUVSs.
