作者研究氟利昂-12(二氯二氟甲烷)及其在400℃的热解产物对实验动物的影响。实验动物为大白鼠和小白鼠,分为五组:第一组对照;第二组为无热解产物的氟利昂-12 500毫克/米~3;第三、四及五组皆为伴有热解产物的氟利昂-12,其浓度分别为500、300及100毫克/米~3。除对照组外,受试动物在一个月期间日夜连续染毒(具有冷却设备连续工作的条件)。浓度为500毫克/米~3含有热解(氟利昂-空气混合物通过400℃管形电炉)产物的氟利昂-12在毒气柜中含氟化氢和氯化氢0.8毫克/米~3;而100毫克/米~3时,毒气
The authors studied the effect of Freon-12 (dichlorodifluoromethane) and its pyrolysis products at 400 ° C on experimental animals. The experimental animals were rats and mice, divided into five groups: the first group control; the second group was freon -12 500 mg / m ~ 3 without pyrolysis products; the third, fourth and fifth groups were all accompanied by heat Freon-12, the product of its resolution, was 500, 300 and 100 mg / m³, respectively. In addition to the control group, the animals were continuously exposed to the sun and the moon for one month (with continuous cooling equipment). Freon-12 containing a product of pyrolysis (Freon-air mixture passed through a 400 ° C tubular furnace) at a concentration of 500 mg / m 3 contained 0.8 mg / m 3 hydrogen fluoride and hydrogen chloride in a gas cabinet; and 100 mg / m 3 When, gas
