Formaldehyde is a harmful gas, which is commonly found in indoor decoration materials, new furniture, new cars and other items. For example, formaldehyde will be released from artificial boards, carpets, sofas, wallpaper, paints and other indoor decoration materials, and plywood and particleboard in new furniture, car carpets, seats and car interiors in automobiles may also contain formaldehyde.

　　Smoking and household cleaners may also release formaldehyde. In order to reduce the impact of formaldehyde on health, decoration materials and furniture with low formaldehyde emission should be selected as much as possible, and ventilation should be carried out frequently.

　　Many items in our daily life contain formaldehyde, such as new wardrobes, new sofas, new tables, new cars, newly renovated new houses, etc., but not all items contain formaldehyde exceeding the standard, so you can use them safely with good ventilation and in addition to formaldehyde.

　　1. Formaldehyde in textiles: Formaldehyde in fiber products is mainly used as dyeing auxiliary and resin finishing agent to improve crease-resistant and shrink-resistant effects.

　　2. Formaldehyde contained in food: duck feet, tripe, shrimp, sea cucumber, fish belly, pomfret, octopus, cuttlefish, hairtail, squid head, tendon, jellyfish, snail meat, cuttlefish larvae, etc.

　　3. Formaldehyde in household air: artificial boards such as plywood, blockboard, medium density fiberboard and particleboard used for interior decoration.

　　1. Decoration materials

　　Decoration materials can be said to be the main force among many indoor pollution sources. Here, we should remind everyone that both ordinary materials and environmental protection decoration materials contain formaldehyde, but only a few. If effective formaldehyde control measures are not taken, indoor formaldehyde will also exceed the standard. Therefore, don't think that in addition to formaldehyde won't be needed if you decorate with environmentally-friendly decoration materials and environmentally-friendly paint.

　　2. Furniture

　　Many furniture are called "zero formaldehyde", which is a particularly ridiculous statement. Unless it is high-quality solid wood furniture, it may not contain formaldehyde, but the price is definitely very expensive, and few ordinary people will buy it. Furniture like chipboard and compressed board contains 100% formaldehyde, which is not only paint and coating, but also the necessary component of the adhesive used in the board. Because it contains a lot of formaldehyde inside, the formaldehyde volatilization period of this kind of furniture is particularly long, generally up to 10 years.

　　3. Plastic products

　　Plastic products may also contain formaldehyde, especially some inferior plastic products, such as plastic bottles, plastic toys, plastic storage boxes and so on. Especially for families with small babies, it is recommended that you buy regular and qualified toys for your children. Don't be greedy for cheap plastic toys, because children often bite toys with their mouths, and the harm can be imagined.
