中文摘要 苯酚（phenol）被广泛应用于工业生产，在水环境中大量检出，具有皮肤灼伤、抑制中枢神经和肝脏损伤等健康毒性.调查了鄱阳湖水体和水产品中苯酚的暴露浓度，采用商值法和概率风险评估法，基于本土人群暴露参数评估苯酚对鄱阳湖流域成人的健康风险.分析结果表明，水体中苯酚浓度范围为ND~556.26 ng·L^-1，水产品中苯酚含量范围在11.98~255.51 μg·kg^-1.鄱阳湖湖区成人饮水健康风险值在3.80×10^-7~8.46×10^-5范围内，湖区南部河流聚集处及北部长江交汇处的成人饮水健康风险较高.成人通过食用鄱阳湖不同种类水产品产生的健康风险范围为2.65×10^-5~1.47×10^-4，食用黄颡鱼和鲶鱼产生的健康风险比其他种类水产品高一个数量级.通过Monte Carlo模拟评估苯酚的健康概率风险，并探讨鄱阳湖流域人群暴露参数敏感性.结果表明鄱阳湖流域成人饮水和水产品食用的95百分位健康风险值处于可接受水平，苯酚环境暴露浓度对健康风险值的影响最大.本研究结果可为鄱阳湖流域水环境中苯酚的风险管控提供参考. 英文摘要 Phenol is widely used in the production of insulation and thermal insulation materials, adhesives, perfumes, coatings for food containers, paints, and pharmaceutical production, and is also widely detected in the aquatic environment. Long-term exposure to phenol can elicit adverse effects, such as skin burn, liver and central system damage. Here, phenol concentrations in the water and aquatic products of Poyang Lake were investigated. Human health risks from phenol to adults and adolescents were also assessed based on local population exposure parameters. The exposure concentration range of phenol in the studied water and aquatic products was not detected (ND)-556.26 ng·L^-1 and 11.98-255.51 μg·kg^-1, respectively. Human health risk based on drinking water in different areas ranged from 3.80×10^-7-8.46×10^-5. Higher human health risks from drinking water was detected in the southern area of Poyang Lake and at the confluence of the Yangtze River to the north. Health risks caused by different types of aquatic products ranges 2.65×10^-5-1.47×10^-4. In particular, human health risks from the consumption of yellow catfish and catfish are an order of magnitude higher than for other aquatic products. Probabilistic risk assessment was also conducted through Monte Carlo simulation to analyze the health risk to the population in the Poyang Lake Basin and assess its sensitivity of different exposure parameters. The 95th percentile health risk of drinking water and aquatic product consumption in the Poyang Lake Basin was calculated as being acceptable. Overall, the concentrations of phenol had the greatest impact on the calculated health risk values. This study provides valuable information for phenol risk management in the Poyang Lake basin.
