The purpose of this study is to measure and analyze the seasonal concentrations of formaldehyde, the total volatile organic compounds (TVOCs), toluene (C?H?), benzene (C?H?), ethyl-benzene (C?H?C₂H?), xylene (C?H₄(CH₃)₂), and styrene (C?H?) in the both classrooms of newly-built school, as of September 2008, and control school.
As a result, formaldehyde and volatile organic compounds among pollutants were just over 100μg/m<SUP>3</SUP>, standard level by law, both in the newly-built school and control school in June and high temperatures in September. As for the total volatile organic compounds (TVOCs), it exceeded 6 times and 3.6 times the standard level in the indoor air by law, 400μg/m<SUP>3</SUP>, in newly-built school and control school respectively, which was usually caused by new learning & teaching tools and clothes of students in March beginning new term. In case of benzene, nothing unusual was found as its highest concentration was 2.9μg/m<SUP>3</SUP> in both schools. However, the concentration of toluene, when its seasonal variation was measured, came to 390.5μg/m<SUP>3</SUP> in control school, reaching 400μg/m<SUP>3</SUP>, the standard level of the total volatile organic compounds, and to 688.0μg/m<SUP>3</SUP> in the newly-built school in March beginning new term. This shows that the concentration of toluene was significantly high in the newly-built school, reaching to 1.7 times the standard level, while the other hazardous organic compounds such as ethyl-benzene, xylene and Styrene, were similar in seasonal concentrations or no detected.
