Expert Q & A: How many pollutants are hidden in the living room?

At present, indoor pollutants mainly include formaldehyde, benzene and benzene series, total volatile organic compounds, etc. How to find pollution sources containing these pollutants is a major problem that plagues consumers. A few days ago, I interviewed relevant professionals and asked them to introduce the nature and source of these pollutants in detail, hoping to help you to remove the pollution from your home.

formaldehyde

Formaldehyde is one of the most well-known harmful substances and is also a major pollutant in newly renovated homes. Formaldehyde is a gas with no color and strong pungent odor. It is highly toxic and can be absorbed through the human respiratory tract, which in turn impairs human health.

In the living environment, formaldehyde mainly exists in the following places: plywood, blockboard, medium density fiberboard, particleboard and veneer; artificial products made of artificial board; wall covering, wallpaper, chemical fiber carpet, foam plastic In materials such as paints and coatings.

Benzene and benzene series

Benzene and benzene are colorless or light yellow transparent oily liquids, characterized by odor, volatile, flammable and toxic. Currently, benzene and benzene have been identified as strong carcinogens by the World Health Organization.

In home-made building materials, paint additives and thinners, waterproof material additives, decorative materials, and adhesives used in the manufacture of artificial panel furniture are the main sources of benzene and benzene.

Total volatile organic compounds

The World Health Organization defines total volatile organic compounds as compounds with boiling points ranging from 50 °C to 100 °C to 240 °C to 260 °C. The main components of volatile organic compounds are aromatic hydrocarbons, oxygen hydrocarbons, aliphatic hydrocarbons, nitrogen hydrocarbons, etc., some of which have been classified as carcinogens, such as vinyl chloride, benzene, polycyclic aromatic hydrocarbons and the like. Interior materials, living and office supplies are the main sources of total volatile organic compounds. Yue Gangju
