The microenvironment of polycarbonate cages housing rats with and without various types of bedding was compared with that of cages that utilized wire floor inserts with different bedding types. Parameters monitored were temperature, humidity, ammonia concentrations and particulates. No differences were noted in the various caging types in relation to temperature and humidity measurements. Significant differences in ammonia concentrations existed in some of the cages when bedding material was used. The use of raised floorwalk inserts also demonstrated significant differences in particulate counts to cages without inserts. The data obtained demonstrated that contact bedding was useful in controlling ammonia generation and that a raised floorwalk insert reduced significantly the aerosolization of bedding particles that could be ingested or inhaled by the rats.
将装有不同类型垫料和未装垫料的大鼠的聚碳酸酯笼的微环境与使用不同垫料类型的带金属丝地板插入物的笼子的微环境进行了比较。监测的参数有温度、湿度、氨浓度和颗粒物。在不同类型的笼子中，温度和湿度测量方面没有差异。当使用垫料时，一些笼子中的氨浓度存在显著差异。使用高架地板行走插入物也显示出与没有插入物的笼子相比，颗粒物计数有显著差异。获得的数据表明，接触垫料有助于控制氨的产生，并且高架地板行走插入物显著减少了大鼠可能摄入或吸入的垫料颗粒的气溶胶化。
