These substances enter the human body through different routes of respiratory tract, and some of them directly produce harm, and some of them have accumulation effect, so that they can be more seriously harmful to the health of human body. Different substances have different effects.
The influence of carbon dioxide with different contents in the air on human bodies is also different: when the concentration of carbon dioxide in the air is lower than 2%, no obvious harm is caused to people, and when the concentration exceeds the concentration, the human respiratory organs can be damaged, namely, under the general condition, carbon dioxide is not a toxic substance, and only when the concentration of carbon dioxide is too high, local irritation symptoms can occur.
The too high carbon dioxide concentration not only can influence the health of a human body, but also can influence the natural environment, and the temperature on the earth is now higher and higher, namely, the carbon dioxide has a heat preservation effect and can raise the temperature of the earth and the sea level because of the increase of the carbon dioxide.
