Abstract

The efficacy of Plasmacluster Ion® (PCI) on bacteria and viruses has been proved, but its inhibitory effects on airborne bacteria and ammonia in the air are unknown. In this study, the effectiveness of PCI was tested using an experimental box, or a model of dogs' daily living space. Experimentally, a box equipped with a PCI generator was filled with gaseous ammonia, and 45 minutes after the device was started (7,000 or 25,000 ions/cm3), the concentration of ammonia was significantly reduced (p<0.05 and p<0.01, respectively). Further, in a model room where two caged dogs could eat and drink, two PCI generators were setup. Two weeks after the generators were turned on, the concentration of ammonia in the room had decreased by more than 50%, and continued to decrease day by day. In addition, the number of colonies of airborne bacteria was suppressed during the deodorization, but rebounded when the generators were turned off. From these results, it appears that PCI is useful for keeping an animal husbandry environment sanitary.
