饱和潜水居住舱内可受多种毒性气体的污染,它们来源于人体代谢产物、供气系统和舱内非金属材料的脱气。为制定我国潜水呼吸用气及饱和潜水舱室气体卫生标准,我们利用现有设备,补充性地进行了高气压毒理实验研究。首先,选择二个常见的内源性污染物一氧化碳和丙酮,以一氧化碳作为无机性窒息性毒气的代表,以丙酮作为有机性麻醉刺激性毒气的代表,通过不同深度模拟潜水条件下的急性毒性试验。观察 Saturated submersible dwellings can be contaminated with a variety of toxic gases, which come from the body’s metabolites, the gas supply system and the degassing of non-metallic materials in the cabin. In order to establish the hygienic standard for diving breathing gas and saturated diving chamber gas in our country, we make use of the existing equipment to supplementally carry out experimental research on high pressure toxicology. First of all, choose two common endogenous pollutants, carbon monoxide and acetone, with carbon monoxide as a representative of inorganic asphyxiant gas, acetone as a representative of organic anesthetic irritant gas, simulate the acute toxicity test under different diving conditions .
