Abstract:
Objective:To analyze the characteristics of toxic substances determination standards in workplaces in China, in order to provide basis for further development of national occupational health standards.Methods:In November 2023, Used descriptive analysis methods, conduct a characteristic analysis of the toxic substance determination standards for workplaces in China issued between 2004 and 2024, including the first drafting situation, standard formulation/revision situation, standard determination methods types, and method performance indicators.Results:The The first drafting unit in the GBZ/T 160 and GBZ/T 300 standards that have been issued is mainly composed of disease prevention and control centers (154, accounting for 60.6%) and the hospital of Occupational disease prevention and control (154, accounting for 60.6%). The regional distribution is North China (65 items, accounting for 25.6%), East China (60 items, accounting for 23.7%), and South China (51 items, accounting for 20.2%). 93.1% of the standards were published between 2004 and 2017; Covering 671 measurement methods.The method types are gas chromatography (367, 54.7%), spectrophotometry (98, 14.6%), inductively coupled plasma mass spectrometry (54, 8.0%), etc. The missing items of standard performance indexes mainly focus on penetration capacity, recovery rate and detection limit. The missing items of penetration capacity and recovery rate are mainly distributed in gas chromatography methods; The missing detection limits and minimum detection concentrations are mainly distributed in spectrophotometry and gas chromatography method.Conclusion:Suggest accelerating the update speed of toxic substance determination standards in the workplace, supplementing the supporting determination methods in GBZ 2.1 standard, focusing on solving common problems in existing standards, gradually improving the standards for missing performance indicators, and gradually carrying out national standard transformation in a hierarchical and phased manner for local or group standards with good practical applications.
