有关临床观察表明,工人在生产环境中接触氯乙烯(30mg/m~3。),既使符合卫生标准,也会出现神经系统变化和白细胞糖原含量降低,故有必要修改现行苏联氯乙烯在车间空气中的最高容许浓度。作者用Wistar种大鼠,共分三组,每组10～30只,其中一组为对照,其余两组给予氯乙烯吸入染毒,每周5次,每次4小时共4个半月。实验所用指标为:体重、自主活动、直肠温度、生物耗氧量、呼吸频率、肝功能(BSP
The clinical observations show that exposure of workers to vinyl chloride (30 mg / m ~ 3) in the production environment, even in line with hygienic standards, also leads to changes in the nervous system and reduction in white blood cell glycogen content, so it is necessary to modify the existing vinyl chloride Workshop air maximum allowable concentration. The authors used Wistar rats, divided into three groups, each group of 10 to 30, one of the control group, the other two groups were given vinyl chloride exposure, 5 times a week, each 4 hours a total of 4 and a half months. Experimental indicators used are: weight, voluntary activity, rectal temperature, biological oxygen consumption, respiratory rate, liver function (BSP
