本实验根据本地区人群生活环境中SO_2污染情况,在SO_2日平均浓度为0.280mg/m~3(为本地区高污染区、下称高值组)、0.154mg/m~3(本地区中污染区、下称中值组)、0.0025mg/m~3(本地区低污染区、下称低值组)的区域中选择了居住于相应区域十年以上,经查体证实健康并无吸烟史或尘毒职业史的成年(33±2周岁)男性,每组30人。采用山城牌GBF-I型肺功能计进行了肺功能五项指标的测试,同时亦以相同条件选择了空气中检不出SO_2的清洁区30名男性成人作为对照组,结果如下: 一、大气中SO_2含量与肺活量(VC)关系:对照组、低值组、中值组、高值组VC均值分别为4200、4080、3960、3740mL;随大气中
According to the SO 2 pollution in the living environment of the population in this area, the average concentration of SO 2 is 0.280 mg / m 3 (for the high-pollution area in this area, hereinafter referred to as high-value group) and 0.154 mg / m 3 Polluted area, hereinafter referred to as the median group), 0.0025mg / m ~ 3 (low-pollution area in the region, referred to as the low value group) of the region chose to live in the corresponding region more than 10 years, physical examination confirmed no smoking Male or adult (33 ± 2 years old) with a history of occupational or dust poisoning, 30 in each group. A total of 30 male adults in the clean area with no detectable SO_2 in the air were chosen as the control group. The results were as follows: First, the atmosphere The relationship between SO2 content and vital capacity (VC): The mean VC values of control group, low value group, middle value group and high value group were 4200, 4080, 3960 and 3740 mL, respectively.
