Knowledge of VOCs

VOC is the English abbreviation for volatile organic compounds, or volatile organic compounds. VOC in the ordinary sense is to direct the emission of organic compounds; but the definition in the sense of environmental protection refers to a lively type of volatile organic compounds, that is, the type of volatile organic compounds that will produce harm.

According to the definition of the World Health Organization, volatile organic compounds refer to various organic compounds with a boiling point of 50 ° C to 260 ° C at room temperature. In China, volatile organic compounds usually refer to organic compounds that protect vapor pressure greater than 70PA at room temperature and boiling point below 260 degrees Celsius at atmospheric pressure. Or at 20 °C, the vapor pressure is greater than or equal to 10 PA and all organic compounds with volatility.

The effects of volatile organic compounds on human health are mainly to stimulate the eyes and respiratory tract, make skin allergies, and cause headaches, sore throats and fatigue. Many volatile organic compounds are toxic and will cause harm to human health, and some volatile organic compounds are carcinogenic, increasing the probability of cancer in the human body.

So where do volatile organic compounds come from?

Volatile organic compounds are mainly divided into indoor and outdoor sources. Among them, indoors, smoking, smoke from cooking, paint in furniture decoration materials, printers, carpets, and even glue, plastic products, etc. will produce VOCs.

Outdoors, most of the volatile organic compounds come from fuel combustion, that is, the exhaust gases emitted by factory smoke pipes and the exhaust gases in transportation.

Relatively speaking, the time at home is much longer than the time outside, so the impact of volatile organic compounds indoors on the human body is greater.

So how to reduce the impact of indoor VOCs on the human body?

In general, the prevention of VOCs is more important than the treatment of VOCs, and when decorating a new home and choosing furniture, it is necessary to choose materials or paints that meet environmental protection standards. You can also choose products with more stringent requirements.

After purchasing, you can add some green plants at home, reduce the impact of VOCs on the human body through plant absorption, and you can also choose some activated carbon packets to adsorb macromolecular suspended particles in the air. In daily life, you can choose appropriate ventilation to increase the fresh air in the room. However, it should be noted that for rooms with heavy pollution and poor ventilation conditions, it may be difficult to achieve the effect of removing odors and reducing VOCs.

Outdoors, volatile organic compounds monitoring devices can be installed to monitor the air quality of residential areas, facilitate real-time monitoring, real-time management, in order to reduce the impact of volatile organic compounds on the human body.
