| 摘 要： | 用被动的扩散采样方法，以磷酸溶液为浸渍试剂吸收室内，外大气环境中的气态氨，然后用分光光度法测定水提取液中的ＮＨ＾＋４，在被观测的３个公寓住宅中，室内氨的平均浓度均高于同期室外氨的平均浓度，初步表明在人类本身可能也是氨的一个来源。

| Abstract: | Simple Passive diffusion samplers were used for the determination of ammonia concentrations in atmosphere.The gas was collected by molecular diffusion on phosp boric-acid-impregnated paper and subsequently determined spectrophotometrically.In a survey of 3 apartments,concentrations of NH3 indoors were higher than those outdoors.These pteliminary data suggest that humans themselves may be a source of ammonia. |
