为了有效地保护高原低氧环境ＴＣＯ环境中作业工人的身心健康进行了研究。浩瀚色谱（山东）应用技术开发有限公司在海拔１５０ｍ、２２６１ｍ、３４１７ｍ和４７５０ｍ４个不同地区采用标化小鼠急性染毒试验测定Ｌｃ５０，并在海拔２２６１ｍ和４７５０ｍ急性染毒后测定ＨｂＣＯ、ＰＯ＿２和ＳａＯ＿２；在海拔２３００ｍ对ＣＯ浓度２６．８／ｍ￣３环境中作业工人进行为期两年的流行病学调查。在４个海拔地区染毒小鼠的Ｌｃ５０分别５７１８ｐｐｍ、３４９２ｐｐｍ、３０７７ｐｐｍ和２２５４ｐｐｍ，三个高原地区毒性分别比平原增加０．６４倍、０．８６倍和１．５４倍；２２６１ｍ和４７５０ｍ染毒小鼠ＨｂＣＯ％值随染毒浓度增加而增大，ＰＯ＿２和ＳａＯ＿２下降（Ｐ＜０．０５）。接触２６．８ｍｇ／ｍ￣３ＣＯ作业工人阳性自觉症状发生率增多，神经行为功能改变，班后呼出气中ＣＯ浓度和ＨｂＣＯ含量提高，班后血胆固醇和血三脂增加，班后ＰＯ＿２和ＳａＯ＿２下降，与对照组比较差异有显著性意义。作者提出以高原地区实测ＣＯ的体积浓度与标准状态体积浓度的换算系数乘以国家卫生标准值为该地区ＣＯ卫生标准，建议海拔２０００～３０００ｍ地区为２０ｍｇ／ｍ￣２，３０００～４０００ｍ为１８ｍｇ／ｍ￣３。

Hygienic standard of CO in the air of workplaces in plateau areas
Hygienic Standard of CO in the Air of Workshops in Plateau Area Details:

Name: Packed column
Specification: 2m*3mm
Model: TDX-01
Application: GB 18554-2001 Occupational exposure limit for carbon monoxide in the air of workshops in plateau areas

In order to effectively protect the physical and mental health of workers in the high-altitude low-oxygen environment TCO environment. Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. used the standardized mouse acute exposure test to determine Lc50 in 4 different areas at altitudes of 150m, 2261m, 3417m and 4750m, and measured HbCO, PO_2 and SaO_2 after acute exposure at an altitude of 2261m and 4750m. ; A two-year epidemiological survey of workers in an environment with a CO concentration of 26.8/m 3 at an altitude of 2300 m. The toxicity of Lc50 in mice infected at 4 altitudes was 5718 ppm, 3492 ppm, 3077 ppm, and 2254 ppm, respectively. The toxicity of the three plateau areas was 0.64 times, 0.86 times and 1.54 times higher than that of the plains; the toxicity of 2261m and 4750m was less. The mouse HbCO% value increased with the increase of the exposure concentration, while PO_2 and SaO_2 decreased (P<0.05). Workers exposed to 26.8mg/m~3CO increased the incidence of positive self-conscious symptoms, changed their neurobehavioral function, increased CO concentration and HbCO content in exhaled breath after shift, increased blood cholesterol and blood trilipid after shift, and decreased PO_2 and SaO_2 after shift , Compared with the control group, the difference is significant. The author proposes that the conversion coefficient between the measured CO volume concentration in the plateau area and the standard state volume concentration is multiplied by the national health standard value for the CO health standard in the region. It is recommended that the altitude of 2000-3000m is 20mg/m~2,3000-4000m is 18mg/ m￣3.
