This study was conducted to evaluate the effects of volatile organic compounds and formaldehyde of newly-built school classroom indoor air on the neurobehavioral functions of students. The elementary schools that were opened in September 2008(as of September 2008) was selected for newly-built school and the elementary school that were opened in March 2006 was selected for control group schools.
The concentration of formaldehyde(HCHO), a hazardous organic compound that exists in the air of classrooms, exceeded the standard value of 108.2㎍/㎥ in newly-built schools while it was 60.8㎍/㎥ in control group schools, which is around 60% of the standard concentration. However, the concentration of the total volatile organic compounds (TVOCs) was 788.9㎍/㎥ and 756.1㎍/㎥ in newly-built schools and control group schools respectively, which are approximately two times higher than the standard concentration.
In newly-built schools, the mean reaction time of additions and symbol digit, respectively 3,020㎳ and 2,398㎳ in pre-exposure were increased to 3,167㎳ and 2,514㎳ respectively in post-exposure. The difference of mean reaction time between pre and post exposure was 146.8 ㎳, or 4.6%, and 116.7㎳, or 4.8%, respectively, showing statistically-significant increase of reaction time(p＜0.05). On the contrary, the difference of reaction time of both tests were not statistically significant in the control group schools.
These results showed that the neurobehavioral performance of newly-built schools students were affected by volatile organic compounds and formaldehyde of classroom indoor air.
