摘要
石家庄市地下商场环境质量调查结果：冬、夏两季平均气温分别为２１．２℃、２３．９℃，气湿５２．８％、７５．９％，气流０．０３６ｍ／ｓ、０．１０５ｍ／ｓ。空气质量指数分别为４．６５和３．７８，空气中ＣＯ２、ＳＯ２、ＮＯＸ、ＨＣＨＯ、ＩＰ和细菌总数６种污染物浓度均有不同程度超标，以ＩＰ和细菌总数两项最严重，超标率ＩＰ冬、夏两季均为１００％，细菌总数分别为９５％和９７．８％。ＣＯ２浓度地下高于地面（Ｐ＜０．０１），ＳＯ２和ＮＯＸ浓度地下略低于地面（Ｐ＞０．０５）。照明冬夏两季均符合卫生要求，噪声夏季超标严重。职工唾液溶菌酶活性本底值：男性冬、夏两季平均值分别为９７．５６±１．５１μｇ／ｍｌ和１００．４２±１．６０μｇ／ｍｌ；女性分别为１２５．１５±１．７５μｇ／ｍｌ和１２８．３１±１．８１μｇ／ｍｌ。
The results of inverstigation on environmental quality assessment of Shijiazhuang underground shop were as follows: The average air temperature, air humidity, air current, and air quality index were 21.2℃, 52.80%, 0.036m/s, 4.65 in winter and 23.9℃, 75.9%, 0.105m/s, 3.78 in summer respectively. These six pollutants, CO 2, SO 2, NO X, HCHO, IP and total bacterial count, were all higher than the environmental health standards in different degrees. Especially the extra standard rates of IP and total bacterial count were 100% and 95% in winter and 100% and 97.5% in summer respectively. CO 2 concentration on underground was higher than that on ground, while the levels of SO 2 and NO X were lower than those on ground. Illumination intensity conformed to standard both in winter and in summer. Noise was much higher than that of standard in summer. The average activity of saliva bacteriolysin: Male's was 97.56±1.51μg/ml in winter and 100.42±1.60μg/ml in summer, Female's was 125.15±1.75μg/ml and 128.31±1.81μg/ml respectively.
