Is the fog poisonous? What poison?

Fog will affect human health. Experts from Hangzhou CDC found that the air contains more than 20 kinds of toxic particles. Under the influence of foggy weather, their harm to human body will be aggravated.

Researchers found that there are more than 20 kinds of toxic substances in the air that are harmful to human body, including 9 kinds of water-soluble ions such as fluorine, chlorine, nitrite, ammonium and sodium, copper, lead, zinc and other 1 1 heavy metal elements, and isotopes of organic carbon and elemental carbon.

These particles are mostly toxic substances, carcinogens and genotoxic mutagenic substances.

The researchers also found that the concentration of fine toxic substances is the highest in winter, which is 1.9 times that in summer, which is related to the relatively stable air flow and small fluctuation in winter.

Health experts say that the above pollutants in the air can easily attach to the water droplets in the fog. Due to the increase of toxic and harmful substances contained in fog droplets, they can penetrate deep into lung tissue after being inhaled into human body, which may easily cause bronchitis, pneumonia, asthma, emphysema and lung cancer, leading to the decline or even failure of cardiopulmonary function.

Studies have shown that the concentration of these substances in the atmosphere increases by 10 mg per cubic meter, the risk of lung cancer increases by 8%, the death rate of heart disease increases by 6%, and the total death rate increases by 4%.

Health experts suggest that it is best not to do outdoor sports when there is heavy fog. Many citizens who do evening self-study and morning exercises in foggy days will feel this way. After exercise, they will feel some pain in their throats and feel very uncomfortable.

"This is caused by inhaling toxic and harmful substances attached to fog drops," experts said.
