Abstract

Using the microthread technique the survival of Escherichia coli MRE 162 in open air was measured in different parts of The Netherlands. The presence of bactericidal compounds (open air factor = OAF) could be demonstrated on several days and quantitated in relative units of OAF concentration. In the absence of ozone the OAF concentration was always low. In the presence of ozone the OAF concentration was dependent on wind direction. At the selected microthread exposure sites air from areas with high traffic intensity contributed more to OAF production than air from industrial areas. OAF production is probably related to the nature of hydrocarbons in the air.

摘要

采用微丝技术，在荷兰不同地区测定了大肠杆菌MRE 162在空气中的存活情况。在几天内均可证明存在杀菌化合物（空气因子=OAF），并以OAF浓度的相对单位进行定量。在没有臭氧的情况下，OAF浓度始终较低。在有臭氧的情况下，OAF浓度取决于风向。在选定的微丝暴露地点，来自交通流量大的地区的空气对OAF产生的贡献比来自工业区的空气更大。OAF的产生可能与空气中碳氢化合物的性质有关。
