复合板确实含有甲醛，因为它们在生产过程中需要使用胶水进行粘合，而胶水中通常含有甲醛。甲醛是一种挥发性有机化合物，长时间或高浓度接触可能对人体健康产生不利影响。然而，只要复合板的甲醛释放量符合标准，比如在的标准是≤1.5mg/L，并且达到E1或E0级标准，其对健康的危害就会比较小。

　　Composite boards do contain formaldehyde because they require the use of glue for bonding during the production process, and glue typically contains formaldehyde. Formaldehyde is a volatile organic compound, and prolonged or high concentration exposure may have adverse effects on human health. However, as long as the formaldehyde emission of the composite board meets national standards, such as the national standard in China which is ≤ 1.5mg/L, and meets E1 or E0 level standards, its harm to health will be relatively small.

　　为了减少甲醛的危害，新安装的复合板应确保充分通风，可以使用绿植或活性炭吸附甲醛，以降低室内甲醛浓度。

　　In order to reduce the harm of formaldehyde, newly installed composite panels should ensure sufficient ventilation, and green plants or activated carbon can be used to adsorb formaldehyde to reduce indoor formaldehyde concentration.

　　需要注意的是，选择复合板时，应优先选择品质可靠、甲醛释放量低的产品，避免使用来源不明或质量不合格的材料。

　　It should be noted that when selecting composite panels, products with reliable quality and low formaldehyde emissions should be given priority, and materials with unknown sources or substandard quality should be avoided.
