A method of reducing the concentration of disinfectant in an environment having a concentration of disinfectant of about 500 ppm or less for a period of time to a lower concentration is disclosed. The method comprises the steps of dehumidifying the environment for the period of time to remove disinfectant, and humidifying the environment with moisture during the period of time to maintain a difference between a lower relative humidity and an upper relative humidity of the environment ranging from about 20 to 50%. A system for decontaminating an environment is also disclosed, comprising a source of disinfectant, a source of moisture, one or more spray generators, and a dehumidifier. A method of decontaminating an environment or enclosure is disclosed, comprising the steps of introducing disinfectant, maintaining liquid disinfectant on surfaces, and dehumidifying the environment to increase the disinfectant concentration is also disclosed.揭露一種降低具有約500 ppm或更少之消毒劑濃度的環境中之該消毒劑濃度一段時間至較低濃度之方法。該方法包含在該段時間中對該環境除濕以移除該消毒劑,及在該段時間中以濕氣對該環境加濕以在該環境的較低相對濕度與較高相對濕度之間維持範圍從約20至50%的差別之步驟。也揭露一種消除環境汙染的系統,包含消毒劑來源、濕氣來源、一或更多個噴霧產生器及除濕器。還揭露一種消除環境汙染或封閉空間的方法,包含引進消毒劑、於表面上維持液體消毒劑及對環境除濕以增加消毒劑濃度之步驟。4‧‧‧消毒劑來源6‧‧‧導管8‧‧‧噴霧產生器12‧‧‧出口16‧‧‧濕氣來源17‧‧‧導管
