One. Do desks and chairs contain formaldehyde?
School desks typically do not contain harmful substances, but if you choose inexpensive or substandard desks and chairs, they may contain formaldehyde.
Formaldehyde content is an important indicator for assessing the environmental friendliness of school desks and chairs. Currently, the Chinese mandatory standard "Limits on Formaldehyde Emission in Interior Decorative and Finishing Materials and Products Made of Engineered Wood" stipulates that the formaldehyde emission in school desk and chair products should be less than or equal to 1.5mg/L. This is primarily to limit potentially harmful chemical components that may be present in the raw materials of school desks and chairs. Therefore, school desks and chairs that do not meet the standard are harmful to both the environment and human health and should not be purchased.
II. What to do if formaldehyde levels in school desks and chairs exceed the standard?
To ensure student safety, schools should consider the formaldehyde content of desks and chairs, and strictly avoid using paints or desks and chairs with excessive formaldehyde levels. Furthermore, local education administrative authorities should collaborate with environmental protection departments to conduct comprehensive surveys or spot checks of desks and chairs in schools within their jurisdiction, promptly addressing any issues and holding responsible parties accountable.
For desks with excessive formaldehyde levels, replacement is necessary. Students should not use desks with elevated formaldehyde levels. If formaldehyde levels are not particularly high, frequent ventilation of the classroom or the introduction of plants like spider plants can improve air quality. This enhances the aesthetic appeal of the classroom and provides a healthier environment for students and teachers.
