Inspection and Analysis for IAQ at the Waiting Room in Lingui Bus Station

Abstract:

Indoor air quality has an important impact on human health.In order to find out indoor air quality (IAQ) condition at the waiting room in Guilin Lingui bus station, in the survey, the waiting room IAQ had been investigated with the carry-home fast inspect instrument from Dec 20^th to Dec 30^th in Lingui Bus Station. The levels of CO₂, formaldehyde(HCHO), particles with diameters of 10 um or less(PM₁₀) and total volatile organic compound(TVOC) had been inspected mostly. Data were analyzed by the SPSS 11.0 and evaluated with synthetic index method of air quality. Results showed that CO₂ concentration was biggest to 878 ppm(standard limit of 1000ppm), PM₁₀ concentration was biggest to 0.14mg/m³(standard value of 0.15 mg/m³), HCHO concentration was biggest to 0.08 mg/m³(standard value of 0.10 mg/m³). The concentration of other pollutants were lower comparatively. The winter air quality of the waiting room in Lingui bus station belongs to the no pollution. It showed that the levels of indoor pollutant were higher than outdoors', too.
