Systematically evaluate the implementation of Specifications of Air Sampling for Hazardous Substances Monitoring (GBZ 159-2004) , so as to provide technical basis for the future standard revision. The semi-structured interview method was used to interview the industry experts from centers for disease control and prevention, occupational disease prevention and control hospitals/institutes, employers, third-party technical service institutions and universities, and the induction method was used to refine the topics and relevant suggestions. Some technical indicators of GBZ 159 are not suitable for the current actual work of occupational health, and need to be revised and improved urgently. The revised GBZ 159 should comply with the current situation of China's industrial development and the development of occupational health testing equipment in the new era, and improve the relevant technical requirements of sampling quality control.
对GBZ 159-2004《工作场所空气中有害物质监测的采样规范》（以下简称GBZ 159）的实施情况进行系统评估，为下一步标准修订提供技术依据。采用半结构式访谈法对来自疾病预防控制中心、职业病防治院（所）、用人单位、第三方技术服务机构和高校的行业专家进行访谈，并运用归纳法提炼内容主题和相关建议。GBZ 159部分技术指标已与现在的职业卫生实际工作不相适应，亟需修订完善。修订后的GBZ 159应符合我国工业发展和职业卫生检测设备发展现状，完善采样质控等相关技术要求。.
