為探討我國粘膠作業(yè)工人的實際二硫化碳 (CS2 )接觸水平以及現(xiàn)有的監(jiān)測方法的代表性 ,浩瀚色譜（山東）應用技術開發(fā)有限公司應用國際上統(tǒng)一的采樣分析方法對某粘膠長絲車間進行了車間空氣中 CS2 濃度和 CS2 作業(yè)工人接觸水平進行了測定 ,并對測定作業(yè)場所的 3種監(jiān)測方法的代表性進行了評價.結果發(fā)現(xiàn) ,用采樣泵活性碳吸收管采樣并以氣相色譜分析法檢測車間固定點 CS2 濃度為 :2 3.2 9± 1.35 m g/ m3,多功能氣體分析儀測定結果為 12 .73m g/ m3,用個體采樣法測得工人的實際接觸水平為 :2 0 .0 5 mg/ m3.因而認為 :不宜以常用的車間內(nèi)空氣濃度來替代工人實際接觸水平 ,因兩者差異有統(tǒng)計學意義 (P<0 .0 1) ;建議工人實際接觸水平應為個體采樣法所測的結果或應以時間加權平均濃度表示為宜.

Determination of Toxic Substances in Workplace Air Sulfide CS2
Determination of Toxic Substances in Workplace Air Sulfide CS2 Details:

Name: Packed column
Specification: 1.5m*4mm
Model: 2%OV-17/Chromosorb W 60-80 mesh
Application: GBZ/T 160.33-2004 Determination of Toxic Substances in Workplace Air Sulfide

In order to explore the actual carbon disulfide (CS2) exposure level of Chinese viscose workers and the representativeness of existing monitoring methods, Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. applied an internationally unified sampling and analysis method to a viscose filament workshop The concentration of CS2 in the air in the workshop and the exposure level of CS2 workers were measured, and the representativeness of the three monitoring methods for measuring the workplace was evaluated. As a result, it was found that the sampling pump activated carbon absorber tube was used for sampling and analyzed by gas chromatography The concentration of CS2 at a fixed point in the workshop detected by the method is: 2 3.2 9± 1.35 mg/m3, the measurement result of the multi-function gas analyzer is 12.73 mg/m3, and the actual exposure level of the worker measured by the individual sampling method is: 20.0 5 mg/m3. Therefore, it is believed that it is not appropriate to replace the actual exposure level of workers with the commonly used air concentration in the workshop, because the difference between the two is statistically significant (P<0.01); it is recommended that the actual exposure level of workers should be the individual sampling method The measured result may be expressed as a time-weighted average concentration.
