Abstract

Introduction: People spend a large part of their time each day indoors. The quality of the air they breathe indoors is an important determinant of their health and wellbeing. Biological parameter become a concern in this study as the activity of people and equipment within the indoor environments is thought to be the principal factor contributing to the build-up and spread of airborne microbial contamination. Other than that, particular activities like talking, sneezing, coughing, walking and washing can generate airborne biological particulate matter. Based on WHO (2004) respiratory infection is the fourth cause of deaths and respiratory disease is a fifth cause of death in the world. Then, the improperly maintained air conditioning systems and exposure to these microbial fragments and metabolites can be a source of wide variety of illnesses (Almoffarreh et. al,2016). Other than that, there is no a NOAEL or a LOAEL (Lowest-Observed-Adverse-Effect Level) has not been identified for bioaerosol exposures. Objectives: To determine the association between concentration of indoor airborne bacteria and fungi and respiratory symptoms among manufacturing workers. To measure the association between concentration of indoor airborne bacteria and fungi , psychosocial risk factors and socio-demographic factors with respiratory symptoms among study respondents. Methodology: 108 workers at one manufacturing factory at Bandar Baru Bangi was selected in this study. Self constructed questionnaire and questionnaire adopted from Job Content Questionnaire (JCQ) and International Union against Tuberculosis and Lung Disease (IUATLD) was used in this study. Generally, the questionnaire used was asked the socio-demographic information, working information, psychosocial work factors and respiratory symptoms. Then, data collection on bacterial and fungal concentration was collected using Duo Sas Super 360 with Trypticase soy agar (TSA) and Sabouraud Dextrose Agar (SDA) agar plate. The agar plate was incubated and the colonies form was calculated. Result: The concentration of bacterial and fungal not exceeds the acceptable limit except for prayer room where bacteria counting exceeded the acceptable limits. There are no significant association between psychosocial factor and concentration of bacteria and fungi with respiratory symptoms. Conclusion: The exposure of bacteria and fungi at study location was safe and acceptable. Thus they study practices a few best practices to maintain the safe exposure of bacteria and fungi indoor such as maintaining air conditioning, frequent cleaning and avoid eating indoor. Keywords: Indoor Air Quality, Bacteria and Fungi Concentration, Manufacturing Workers, Psychosocial Factors
