Abstract

Air pollution in steel making operations effect to respiratory health. This study aimed to measure the dust exposure and evaluate the respiratory health among steel workers. A cross sectional study was conducted among 402 male workers. Respiratory symptoms using British Medical Research Council (BMRC) Questionnaire while lung function was measured The airborne dust [PM2.5, PM10, and Total Particulate Matter (TPM)] were monitored by Handheld 3016 Counter. All the parameters studied exceeded the limit of Malaysian guideline standard. Prevalence of chronic phlegm, chest of tightness, and shortness of breath were 35.8 %, 32.8 %, 23.4 %, and 22.4 %, respectively. significant differences between shortness of breath and work section (2=9.236, p=0.026) and %FEV1/FVC with work section [F (3, 3.98=3.194), p=0.025]. Smoking was associated with chronic cough (Adj OR =1.07, 95% CI: phlegm (Adj OR =1.05, 95% CI: 1.03 - 1.08), and shortness of breath (Adj OR = 1.05, 95% CI: 1.00 past respiratory illnesses was associated with chest tightness (Adj OR = 2.24, 95% CI: 1.04 - 4.84) and (Adj OR = 4.16, 95% CI: 1.92 - 9.92). Duration of employment was associated with FEV1 (β=-0.025, 0.020) while past respiratory illnesses was associated with %FEV1/FVC (β =-1.784, 95% CI: -3.017 workers are at risk of developing respiratory symptoms and lung function impairment.
