| Περίληψη: | Some testing methods specified in the current national occupational health standard series GBZ/T 160 and GBZ/T 300 for the determination of toxic substances in workplace air fail to meet the requirements for the high-quality development of occupational health. The study collects the standards of GBZ/T 160 and GBZ/T 300, and summarizes the existing problems in their determination methods based on practical testing work. Among the current GBZ/T 160 and GBZ/T 300 standards, the standard determination methods for some toxic substances have multiple deficiencies: the sampling methods cannot satisfy the needs of green, low-carbon and ecological development; toxic substances in different existing states in workplace air cannot be collected accurately; personal sampling and long-term sampling are difficult to implement; the scope of application is limited; highly toxic and hazardous reagents are adopted; the correlation coefficients of standard curves are unsatisfactory; method minimum quantitative concentrations are relatively high; the accuracy and desorption efficiency are poor; the sample stability period is short; and only spectrophotometric methods requiring large amounts of organic solvents are formulated for certain substances. Therefore, the current standard determination methods for toxic substances in workplace air in China need further optimization and improvement. It is urgent to revise national occupational health standards, develop advanced, efficient and high-quality standard determination methods, so as to further boost the development of new quality productive forces in the occupational health industry of our country. |
