Bosten Lake is the main fishing and grazing area in Xinjiang. The pollution of phthalate esters (PAEs) in water has attracted much attention, but limited research has been conducted on PAEs in Bosten Lake. The distribution of PAEs in fifteen sampling sites of surface water in the dry and flood seasons were investigated to explore the content level of PAEs in Bosten Lake, and the risk was evaluated. Seventeen PAEs were detected by GC-MS after liquid-liquid and solid-phase purification. Results showed that the content of ∑PAEs in the water during dry and flood seasons is ND-26.226 μg/L and ND-7.179 μg/L. The content of PAEs in the water of Bosten Lake is at a medium level. DBP and DIBP are the main PAEs. The content of PAEs is related to the physicochemical properties of water, and the physicochemical properties of water in dry season have a more serious impact on PAEs. PAEs in water mainly come from domestic pollution and chemical production. The results of health risk assessment indicate that PAEs in water do not pose a carcinogenic risk or a non carcinogenic risk to human, which can meet the conditions of Bosten Lake as a fishing ground and livestock base, but the pollution of PAEs cannot be ignored.
博斯腾湖是新疆主要的渔业和畜牧业区。水中邻苯二甲酸酯（PAEs）的污染引起了广泛关注，但对博斯腾湖 PAEs 的研究有限。本研究调查了博斯腾湖丰水期和枯水期 15 个地表水采样点中 PAEs 的分布情况，以探讨博斯腾湖水中 PAEs 的含量水平，并进行风险评估。采用液液萃取和固相萃取净化后，通过 GC-MS 检测到 17 种 PAEs。结果表明，丰水期和枯水期水中∑PAEs 的含量分别为 ND-26.226μg/L 和 ND-7.179μg/L。博斯腾湖水中 PAEs 的含量处于中等水平。DBP 和 DIBP 是主要的 PAEs。PAEs 的含量与水的理化性质有关，枯水期水的理化性质对 PAEs 的影响更为严重。水中的 PAEs 主要来自于生活污染和化工生产。健康风险评估结果表明，水中的 PAEs 对人体没有致癌风险或非致癌风险，可以满足博斯腾湖作为渔业和畜牧业基地的条件，但不能忽视 PAEs 的污染。
