Because it contains organic volatile gases that have been dried, there are basically no volatiles and are not toxic. The main way for industrial toxic gases to enter the human body is through the respiratory tract. The human respiratory tract has a strong ability to absorb toxic gases. The main absorption parts are the bronchi and alveoli. Generally, the total area of human alveoli is between 1 and 4, while the alveoli have only a thin wall of 1-4 μm. Its surface is carbonic acid-containing liquid. The alveolar walls are There are extremely rich capillaries, so the alveoli have a very strong ability to absorb poisonous gases.
For gases and vapors with high water solubility, such as sulfur dioxide and chlorine, when passing through the respiratory tract, they are easily dissolved by the upper respiratory tract mucus and cannot easily reach the alveoli. However, when the concentration is high or the breathing depth is large, it depends on the particle size and water solubility of the poisonous gas. sex. In addition to the particle size and water solubility, the speed at which the respiratory tract absorbs poisonous gas is also related to the concentration of poisonous gas in the air, the human body’s pulmonary ventilation, and the time of exposure to the poisonous gas.
