摘要目的:依据GBZ/T298-2017《工作场所化学有害因素职业健康风险评估技术导则》的评估方法对某邻苯二甲酸二辛酯[di（2-ethylhexyl）phthalate，DEHP]生产企业进行风险评估，探讨定性评估法和半定量评估综合指数法的适用性。方法:于2017年7月至8月，采用整群抽样的方法选择河南省某DEHP生产企业为对象，进行职业卫生现场调查和工作场所环境监测，依据GBZ/T 298-2017《工作场所化学毒物有害因素职业健康风险评估技术导则》中的定性评估法、半定量评估综合指数法对其进行职业健康风险评估，分析比较两种风险模型评估结果异同。结果:该企业采用定性评估法、半定量评估综合指数法的职业健康风险等级结果分别为4级（高风险）、2级（可忽略风险）。结论:半定量评估综合指数法可更全面、准确的评估DEHP生产企业引起的职业健康风险。

abstractsObjective:To find the risk assessment model of [di (2-ethylhexyl) phthalate, DEHP] fitting well for producing companies.Methods:The Cluster Sampling method was used in selecting a DEHP producing company in the occupational health and workplace environment monitoring study conducted between July and August in 2017. Data was collected by site evaluating and workplace environment monitoring. According to GBZ/T 298-2017《Technical Guidelines for Occupational Health Risk Assessment of Chemical Hazards in the Workplace》, a qualitative assessment method and a semi-quantitative comprehensive index method were chosen as the models and were compared.Results:The occupational health risk of the two methods rated 4 (high risk) and 2 (negligible risk) .Conclusion:The semi-quantitative comprehensive index method is more comprehensive and accurate when used to assess the occupational health risk caused by DEHP.
