1989年12月中旬,我省牧工商大楼营业厅因室内通风不良,取暖炉出烟不畅,造成CO气体高浓度污染。我们随机选择30名无职业接触CO的营业员为暴露组,定时测定人体呼出气中的CO浓度(COb),并按汪国雄等确立的COb-COHb％含量公式:COHb％=(9.3897COb+513.02-22.8751)~(1/2)推算人体COHb含量,结果分析如下。
In mid-December 1989, the business hall of the animal husbandry building in our province was poorly ventilated due to poor ventilation inside the heating furnace, resulting in high concentration of CO gas. We randomly selected 30 non-occupational CO sales staff for the exposure group, regular determination of CO concentration in the body exhaled breath (COb), and according to Wang Guoxiong and other established COb-COHb% content formula: COHb% = (9.3897COb +513.02 -22.8751) ~ (1/2) calculate the body COHb content, the results are as follows.
