A system using unlabeled, metallic mercury for generating low-dosage vapor for animal experiments is described. The system consists of four acrylic plastic chambers: one chamber containing the mercury source, one for mixing the mercury vapor with air, one exposure chamber, and one containing activated coal filters and mechanisms for regulating the airflow. The chambers are connected to each other by means of 80-mm-diameter polyvinyl chloride tubes reinforced with wire. Additional control and supporting equipment is also used. The system is easy to set up and requires minimal attendance during use. A standard deviation of 3-4% in the mercury vapor level during 6 h of exposure is typical. The conditions for the animals during exposure and the safety for the personnel during use are optimal.
描述了一种使用未标记的金属汞来产生低剂量蒸汽用于动物实验的系统。该系统由四个丙烯酸塑料腔室组成：一个腔室装有汞源，一个用于将汞蒸汽与空气混合，一个暴露腔室，还有一个装有活性炭过滤器和调节气流的装置。这些腔室通过直径80毫米、用金属丝加固的聚氯乙烯管相互连接。还使用了额外的控制和辅助设备。该系统易于设置，使用过程中所需的照看最少。暴露6小时期间汞蒸汽水平的标准偏差通常为3 - 4%。动物暴露期间的条件以及使用过程中人员的安全性都是最佳的。
