7名健康男性受试者连续90天(每9天为一个单元)暴露于10种低浓度混合空气污染物中,浓度分别为O_2,20.5±0.119％,N_276.4±3.347％,CO_20.904±0.101％;CO23.125±3.537ppm(以下为ppm单位),NO_20.471±0.097; Cl_2 0.083±0.012,HC10.69±0.195;HF 0.091±0.017; NH_30.955±0.215;CCI_2F_294.95±12.38;C_xH_γ9.040±2.35;Hg0.003±0.0002mg/m~3。除每天记录体重、体温、脉率、呼吸,血压和主观感觉外,还检测了脑电图、心电图,皮肤电位,呼吸波描记,两位数表计算,视觉运动反应时,短期记忆,闪光融合临界频率,血液PH,血液气体,全血胆碱酯酶,血清碱性磷酸酶,碳氧血红蛋白,血清铁,白细胞吞噬功能,血液细胞学检查,尿中17-OH皮质类固醇的排出量。
Seven healthy male subjects were exposed to 10 low concentrations of mixed air pollutants for 90 consecutive days (one unit every 9 days) at concentrations of O 2, 20.5 ± 0.119%, N 2 76.4 ± 3.347%, CO 2 0.904 ± 0.101%; CO23.125 ± 3.537 ppm (ppm units below), NO_ 20.471 ± 0.097; Cl_2 0.083 ± 0.012, HC10.69 ± 0.195; HF 0.091 ± 0.017; NH_30.955 ± 0.215; CCI_2F_294.95 ± 12.38 ; C_xH_γ 9.040 ± 2.35; Hg 0.003 ± 0.0002 mg / m ~ 3. In addition to daily recording of body weight, body temperature, pulse rate, respiration, blood pressure and subjective perception, EEGs, electrocardiograms, skin potentials, respiratory wave tracings, two-digit table calculations, visual motor responses, short-term memory, flash fusion Critical frequency, blood pH, blood gas, whole blood cholinesterase, serum alkaline phosphatase, carboxyhemoglobin, serum iron, leukocyte phagocytosis, hematological examination, urinary excretion of 17-OH corticosteroids.
