Abstracts: ISEE 22nd Annual Conference, Seoul, Korea, 28 August-1 September 2010: Work Environment and Respiratory Effects
A prospective study was carried out to determine the status of lung functions among printing workers who are exposed to solvent. An intervention program was carried out in order to educate the workers on the hazards of solvent.
Of the 60 workers, 54 were followed up for their lung functions, as another 6 had left factory. These workers worked in the production line. They were exposed to solvent for almost 2 years from the last measurement of the lung functions. Questionnaire was used to obtain information on sociodemographic background. Spirometer model Chestgraft HI-101 was used to execute the lung function test. Validated questionnaire on knowledge and practices were used for the intervention program.
Lung function parameters: FEV1% predicted, FVC% predicted, and FEV1/FVC% predicted showed significant difference between previous data and present findings (P < 0.001, P = 0.011, P = 0.004) before and after the intervention.
The comparison between previous lung functions with the present data showed significant impairment. The respondents were identified as having obstructive lung functions over 2 years' exposure to the organic solvent. The effectiveness of the intervention program was proven as there was a significant difference in the scores obtained before and after the intervention.
