However, the aquatic hazard of these compounds to algae which is ubiquitous in surface water is still unclear. In this study, nine <em>N</em>-nitrosamines were investigated in the Pearl River Delta, China, with the total concentrations ranged from 27.0 to 727.6 ng/L. After that, four frequently detected <em>N</em>-nitrosamines—<em>N</em>-nitrosodiethylamine, <em>N</em>-nitroso-di-n-propylamine, <em>N</em>-nitrosopyrrolidine, and <em>N</em>-nitrosodibutylamine—were selected to explore their toxic mechanisms when individually or in combination exposed to <em>Selenastrum capricornutum</em>. The results revealed that the four <em>N</em>-nitrosamines and their mixtures all inhibited algal growth, with toxicity ranking as follows: <em>N</em>-nitrosodiethylamine > <em>N</em>-nitroso-di-n-propylamine > <em>N</em>-nitrosodibutylamine > <em>N</em>-nitrosopyrrolidine. Exposure to <em>N</em>-nitrosamines significantly altered the activities of superoxide dismutase and catalase and increased malondialdehyde levels. Additionally, total protein and photosynthetic pigment contents were significantly inhibited, especially under high-concentration exposure, leading to severe impairment of algal photosynthesis and growth. Toxicity modelling indicated that the quaternary mixture exhibited an additive effect on algal toxicity, with an inhibition of 15.6 % at environmental concentrations. However, risk quotients modeled using ECOSAR were significantly overestimated compared to experimental toxicity data. Risk assessments based on measured levels of <em>N</em>-nitrosamines in Pearl River Delta freshwater systems indicated that the risk quotients were all below 0.1. Nevertheless, the ecological risks posed by <em>N</em>-nitrosamines in mixture forms were slightly higher.
