Abstract: Aiming at the problem of indoor ammonia pollution in civil buildings, the research progress of current status, polluting sources, releasing rules, effects on human health and related control measures of indoor ammonia pollution at home and abroad was introduced. The results show as follows: the indoor ammonia pollution in China is complex, and the hairdressing sites are highly polluted with ammonia; in other civil constructions, the indoor ammonia pollution is mainly due to the construction and decoration materials and has regional differences, with worse pollution in northern part of the country than in southern part. The pollution abroad is less serious in foreign developed countries. The research on the effect of low-level ammonia pollution on human health is rare both at home and abroad. The domestic researches focused on indoor ammonia pollution prevention while foreign researches mainly focused on the control of indoor ammonia pollution at the field of husbandry and aquaculture. China had established a series of standards or regulations about indoor ammonia pollution while there were no related reports in other developed countries except Finland. Finally, suggestions on further researches on indoor ammonia pollution were put forward.
