Abstract

Summary: Introduction: The photocopy workers are potentially exposed to high concentration of particles emitted from photocopiers as it is the source of indoor air pollutant which includes of fine particles (PM25) and ultrafine particles (UFP). Previous studies have shown particulate air pollution influences the respiratory symptoms and associated with decrease in lung function as these tiny particles are able to travel deeply into the respiratory tract and reaching the lungs. Objective: The aim of this research is to determine the relationship of exposure to PM25 and UFP with respiratory health among photocopiers workers. Methodology: A cross-sectional comparative study was involved of 30 workers of photocopiers as the exposed group and 30 of administrative staff as comparative group who fulfilled the inclusive criteria. The sampling of personal exposure to PM25, UFP have been conducted and questionnaire adapted from standardized A TS has been used to assess the respiratory symptoms and lung function test have been conducted to each respondents. Result: The result showed the mean personal exposure to PM25 (62.30 /-lg/m3) and UFP (14567.10 pt/cc) among exposed group were much higher compared to the comparative group (PM25= 13.10 /-lg/m3, UFP= 3662.60 pt/cc). There was a significant association between personal exposure to PM2.5 with lung function of FVC % predicted (r= ¬0.404, p= 0.027) and UFP with lung function of FEV I % predicted (r= 0.377, p=0.040). The reported respiratory symptoms of cough (26.7%), phlegm (16.7%), chest tightness (3.3%), and wheezing (6.7%) were much higher in exposed group compared to comparative group. Conclusion: The continuous exposure to the PM2.5 and UFP among photocopiers workers can cause lung function impairment as the findings showed respiratory symptoms was higher among exposed group compared to the comparative group. There was also a significant association between personal exposures to PM2.5 and UFP with lung function among exposed group. The photocopy owner should control the emission and exposure to PM2.5 and UFP by regularly service or maintenance of photocopy machine and improve the indoor environment by ensures good ventilation.
