Air quality and adverse health effects of personal who exposed to airborne at Library Thaksin University, Phatthalung Campus

Abstract

This study is a survey research with the objective to measure the air quality inside the library building. Thaksin University Phatthalung Campus that may affect the health of personnel and service users. The indoor air quality parameters (IAQ) measurement instrument, consisting of an Anderson 1-stage cascade impactor, was used to collect bacteria and fungi samples. The indoor air quality parameters (IAQ) measurement instrument, consisting of an Anderson 1-stage cascade impactor, was used to collect bacteria and fungi samples. and then used to measure the amount of infection along with temperature measurements both inside and outside the building and a questionnaire on health problems of those in the building was used. To interpret the air quality results that affect the recipient exposed to indoor air pollution. There are 2 groups of samples: 20 personnel working within the library and 349 other service users. Statistics used for analysis are frequency (Frequency), percentage (Percentage), mean (Mean) and standard deviation (Standard Deviation) and the Chi-Square Test statistics with a confidence level of 95%. The results of the study showed that the temperature both outside and inside the building. which is an indicator of thermal comfort with a temperature between 24.53-26.4 °C compared to the optimum indoor temperature specified in the Department of Health announcement between 24.0-26.0 °C. Inside the library building, therefore, the temperature is suitable according to the criteria. As for the concentration of bacteria and fungi, none of the areas exceeded the standard, so it did not affect health. But there may be symptoms of Sick Building Syndrome if exposed to bacteria and fungi directly, such as nasal congestion, cough, dry throat, and headache, etc., which will be found among personnel who work more than service users because they spend approximately every day in the building. 7-8 hours.
