氨是碱性刺激性气体,低浓度对粘膜有刺激性作用,高浓度除能造成皮肤及上呼吸道粘膜炎症外,还能引起肺充血肺水肿等。关于厕所空气中氨的卫生学标准,未见资料记载。为了配合我国铁路客车集便专题研究工作,首先探讨现行客车厕所空气中氨的浓度范围,是一项迫切需要解决的问题。它除了提供现行客车厕所与集便装置车厕所空气中氨鉴定数据外,而且帮助选择除臭方式提供依据。本次试验从1979年1月～1980年3月进行,现做如 Ammonia is a basic irritant gas, low concentrations of mucous membrane irritant, in addition to high concentrations of the skin and upper respiratory tract can cause mucosal inflammation, but also can cause pulmonary congestion and pulmonary edema. About toilet air ammonia hygiene standards, no information recorded. In order to tie in with our country railway passenger car collectors special topic research work, first of all, to explore the current passenger toilet air ammonia concentration range is an urgent need to be addressed. In addition to providing current airborne ammonia qualification data from toilet latrines and toilet lavatories, it also provides a basis for choosing a deodorising mode. The test from January 1979 to March 1980, is doing like
