The harm of VOC to human bady

VOC contains a variety of volatile organic compounds at room temperature, and there are more than 100 vocs in the general indoor environment. The main ingredients are: benzene series, organic chloride, freon series, organic ketone, amine, alcohol, ether, ester, acid and petroleum hydrocarbon compounds. Among the common VOC types are toluene, xylene - dichlorobenzene ethylbenzene, styrene, formaldehyde, acetaldehyde, etc. Benzene, toluene, halogenated olefin (trichloroethylene, dichloroethylene) and other carcinogenic substances have been suspected or determined.

VOC has a great influence on human health. VOC can participate in the reaction of nitrogen oxides under the action of outdoor sunlight and heat and form ozone, which leads to poor air quality and is the main component of summer smog.

The indoor effects of VOC on human body can be divided into three types:

1. Smell and senses, including sensory stimulation, feeling dry;

2. Pathological condition caused by mucosal irritation and other systemic toxicity, including irritation of eye mucosa, nasal mucosa, respiratory tract and skin. VOC can easily pass through the blood-brain barrier, leading to the inhibition of the central nervous system, resulting in headache, fatigue, drowsiness and discomfort.

3. Genotoxicity and carcinogenicity. Of course, the effect of VOC on human is related to its concentration.
