Research outline We investigated indoor air pollutants and changes in concentrations of houses using insecticides and preservatives. In addition, passive samplers for VOC measurement were evaluated by field test. Implementation status In the wooden house where high concentration (3800 μg / m 3) of paradichlorobenzene, an insecticide, was detected in indoor air, the change of…

Wool is easy to migrate, half of it remains after washing. Commercial furniture has many problems. It is desirable to ask for a used item at…

Formaldehyde is highly concentrated in a sealed space with less ventilation. Baking out (volatilizing the chemical substances contained in the material by raising the temperature) may be difficult to see the effect on formaldehyde. Volatile organic compounds have been effective. As a comprehensive measure, do not use building materials containing formaldehyde and volatile organic compounds…
