Abstract:
Introduction:Sanitation facility supply and service availability of Mongolia is essential due to the slow process of
bacterial decomposition which is getting significant difficulties because of the cold and arid climate.
Only 37 percent of Ulaanbaatar’s population is connected to the central sewerage system, and the
majority of ger area residents, or 95 percent, use pit latrines in demand of sanitation facility. Numerous
studies have shown that the main contaminant of the soil in ger area were pit latrines. It not only pollutes
the environment but also affects human health. There is a lack of awareness about the transmission
of infectious diseases and options of new sanitation facilities and poor knowledge and bad conditions
to introduce new drainage systems. Most pit latrines in ger areas are of poor quality and do not meet
relevant standards.
Goal:To determine the effect of ”Gipon” ionized disinfectant solution produced by Japanese technology for
disinfecting pit latrines
Material and Methods:This study was conducted in December 2019 using a random sampling method. Five households in ger
areas were selected and pit latrines were disinfected by ”Gipon” ionized disinfectant solution.
Results:The survey covered pit latrines of 5 households in the 21st khoroo of Bayanzurkh district. All owners
allowed to participate in the survey. The pit latrines are located approximately 9.8 meters away from the households participated in survey. They have been utilized it for 7.6 years and used by an average of 6 people per day. For inner cover, 60.0 percent are lined with wood, and 40.0 percent are cleaned once a month. Before the use of the disinfectant solution, having taken the swab from door handles, floors and walls of the toilet and were detected Enterobacter spp, E.Coli, and Pseudomonas spp in all samples.
However, after one and 24 hours of spreading of the disinfectant solution, the amount of intestinal
coliform bacteria and E. coli was reduced dramatically and in some places no bacterial were detected.
72% of the soil near the latrines in the study covered ger areas was contaminated with bacteria. In
terms of E.Coli contamination in soil, 60% of them were contaminated in low degree and 32% were
medium and 8% were high degree. Anaerobic microorganisms such as Cl.prefrings were accounted for 82% of the total sample, 19% moderate and 81% low contamination.
Conclusion:Intestinal coliform bacteria (Enterobacter spp, E.Coli, Pseudomonas spp) and pathogenic bacteria
(Serratia spp, Staphylacoccus spp) were not detected and the number of fungi was sharply reduced
after 1 and 24 hours using Hypon disinfectant. No intestinal pathogens (Salmonella spp, Citrobacter
freundii) were found in the soil near the latrine. The amount of coli titers was reached to the acceptable
limits. According to this study, the disinfection activity of “Gipon” solution was ranging from 105 to 104.
