许多新合成的化学物质都可造成大气污染。因此研究在大气污染条件下居民的过敏性疾病发病情况是很必要的。本调查评价了大气污染对儿童免疫反应、过敏性疾病发病率以及对机体维生素C水平的影响。调查了工业城市的某些住宅区。A区:空气受化学和石油化工生产排放物(硫化氢、碳氢化合物、丙酮、乙烯化氧、酚等)污染,B区:为新建小区,空气未被污染。对1967～1978年的大气分析表明,硫化氢、丙酮、乙烯、苯、异丙苯、过氧化氢浓度均低于各自最大允许值,仅酚浓度有时超过最大允许值的0.2～0.8倍。调查地区儿童的居住生活、物质
Many newly synthesized chemicals can cause air pollution. Therefore, it is necessary to study the incidence of allergic diseases among residents under air pollution conditions. The survey evaluated the effects of air pollution on childhood immune responses, the incidence of allergic diseases, and the effects on vitamin C levels in the body. Surveyed some residential areas in industrial cities. Zone A: Air is polluted by chemical and petrochemical production emissions (hydrogen sulfide, hydrocarbons, acetone, ethylene oxide, phenol, etc.). Zone B: is a new district where air is not contaminated. Atmospheric analysis from 1967 to 1978 showed that concentrations of hydrogen sulfide, acetone, ethylene, benzene, cumene and hydrogen peroxide were lower than their respective maximum allowable values, and only the concentration of phenol sometimes exceeded 0.2 to 0.8 times the maximum allowable value.
