我国室内甲醛污染的主要来源为：家具、纺织品和日用品，以及室内香烟、燃气、熏香等。
The main sources of indoor formaldehyde pollution in China are furniture, textiles and daily necessities, as well as indoor cigarettes, gas, incense and so on.
1、甲醛作为性能优质的工业原料，被用于制造脲醛树脂、酚醛树脂和三聚睛胺甲醛树脂等强力粘合剂。
1. As an industrial raw material with high performance, formaldehyde is used to manufacture strong adhesives such as urea formaldehyde resin, phenolic resin and trimethylamine formaldehyde resin.
而这些粘合剂，被广泛用于人造板材、家具、建筑装饰和装修材料。
These adhesives are widely used in artificial boards, furniture, architectural decoration and decoration materials.
所以，以人造板材为原料的家具，以及装修材料，都成为室内甲醛污染的重要来源。
Therefore, furniture with artificial board as raw material and decoration materials have become an important source of indoor formaldehyde pollution.
2、甲醛是一种重要的纺织品整理剂，服装面料生产中，为了达到防皱、防缩、保持印花染色耐久性、改善手感等目的，就必须在面料中添加甲醛，尤其是纯棉纺织品。
2. Formaldehyde is an important textile finishing agent. In the production of garment fabrics, formaldehyde must be added to the fabrics, especially pure cotton textiles, in order to achieve the purposes of anti wrinkle, anti shrinkage, maintaining the durability of printing and dyeing and improving the hand feel.
所以，纺织品也是家庭甲醛污染的重要来源。
Therefore, textiles are also an important source of household formaldehyde pollution.
3、油漆、涂料、化妆品、清洁剂、香烟烟雾、燃气灶、熏香（包括蚊香、线香、棒香），都会释放大量甲醛。
3. Paints, coatings, cosmetics, detergents, cigarette smoke, gas stoves and incense (including mosquito repellent incense, thread incense and stick incense) will release a large amount of formaldehyde.
