Abstract
Purpose: This study was to find out the influence on eyes of indoor air quality in college students taking course, such as Sick-building syndrome symptoms and effects on the eye in new-built university buildings. Methods: We selected a new building in a university located in Metro Seoul and college students in a department for the study. The number of total participants was 33, to whom questionnaire surveys were conducted in advance to check individual traits (gender, age, whether to smoke, whether to wear contact lenses, or whether to drink). The first questionnaire surveys and checking of ocular symptoms to first indoor hazardous materials were conducted in October and two months later the second surveys and checking were carried out in December. The indoor air quality was measured when conducting the first questionnaire surveys and the second questionnaire surveys; especially measurements of gaseous materials such as aldehydes and VOCs in the indoor air were conducted. Results: Indoor air quality of the new building was as follows: formaldehyde level was 22.90 ${\mu}g/m^3$ in the first measurement and 16.79 ${\mu}g/m^3$ in the second measurement. In addition, most materials showed higher value in the first measurement. The level of TVOC was statistically significant (p<0.05) decreased on 448.54 ${\mu}g/m^3$ in the first and 62.55 ${\mu}g/m^3$ in the second. In clinical assessments to check ocular symptoms caused by eye irritations, dry eye syndrome was found in the first and second exposures. When comparing the first and second assessments, dry eyes deteriorated in the morning of the second attempt compared to the first one. Conclusions: In the survey of ocular symptoms and the measurement of indoor air quality, the level of formaldehyde was measured higher in the second attempt than the first; thus, it was confirmed the influence of indoor air quality in a new building upon ocular symptoms of occupants.
