Quantity and Type of Microorganism in Indoor Air at the Passenger Terminal : A Case Study of International Airport.

Abstract

A descriptive cross-sectional study was describe type and the amount of microorganism in indoor air at the passenger terminal of the International Airport, one of the sampled bacteria and fungi in Terminal A and B at the check in point, a passenger room and baggage checkpoint With samples of microorganisms in the air. The study results found that the point that most bacteria were found include baggage checkpoint terminal B (574.38± 145.86 CFU/m³) the passenger room terminal B (539.88± 42.72 CFU/m³) baggage checkpoint terminal A (386.88 ± 249.00 CFU/m³) and the passenger room terminal A (336.18± 48.27 CFU/m³), respectively. The fungi found at most include a baggage checkpoint terminal B (627.50± 323.33 CFU/m³) the passenger room B (530.25 ± 166.14 CFU/m³) and baggage checkpoint terminal B (507.50± 165.32 CFU/m³), respectively. Types of microorganisms in the air. Bacteria there was 6 types of Staphylococcus spp., Micrococcus spp., Pseudomonas spp., Bacillus spp., Enterobacteriaceae and Streptococcus spp. Fungi there was 5 species of Cladosporium spp., Fusarium spp., Penicillium spp., Aspergillus spp. and. Alternaria spp. Comparison of microbial sampling intervals in the morning and evening sessions by testing different types of bacteria and fungi in indoor air all the points difference is not statistically significant (p-value = 0.05) compared to the introduction indoor air quality Singapore standard of microbial. The amount of bacteria in indoor air in conclusion suggested value (<500 CFU/m³) excepted in the passenger room terminal B, Baggage checkpoints terminal B and terminal A. Amount of fungi in indoor air was in the recommended threshold. Except the check in point terminal A and B, at the baggage checkpoints terminal A and B and passenger room B. Compared to standard buildings. Hong Kong's air quality in public buildings. The amount of microorganisms <500 CFU /m³ air quality is excellent. The content of <1,000 CFU/m³ in the air quality. However, there should be precautionary measures to reduce the quantity of microorganisms in a quantity exceeding the recommended values.
