居住区大气中酚卫生标准的探讨

A Study on Hygienic Standard of the Phenol in the Atmosphere at Populated Area

本文调查了生产酚醛树脂和环氧树脂两个使用酚的工厂周围300米内空气酚污染状况,做了酚嗅阈实验,嗅阈值为0.158mg/m^3。酚污染夏季较冬季重。当日平均和一次最大浓度分别为0.018～0.055mg/m^3和0.125～0.155mg/m^3时,对学龄儿童尿酚含量无影响。结合快速推算法和现场实测,建议酚的日平均和一次最高容许浓度分别为0.015mg/m^3和0.045mg/m^3。

The state of atmosphere Pollution within 300 meters around two factories which Produced bakelite and epoxy resin was investigated. At same time, the olfaction threshold of phenol was tested.Our findings suggest that the concentration of olfaction threshold of Phenol was 0.158mg/ m3. The atmosphere Pollution of phenol in summer was more serious than that in winter. The urino-phenol of school-age children was not affected when daily average maximum concentration was 0.018 rag/m3 to 0.055mg/m3 and momentary maximum content was 0.125mg/m3 to 0.155 mg/m3. Combining high-sPeed method with the field investigation, we suggest that 0.015mg/m3 and 0.045mg\m3 may be defined as the standard of the daily average maximum allowable concentration and the momentary maximum allowable concentration in our country.
