Certain areas of coal contain more fluorine, arsenic and other inorganic pollutants, combustion can contaminate indoor air and food, inhaled or ingested, can cause fluorosis or arsenic poisoning.
Cooking. Cooking fumes not only hinder general health, but more importantly, they contain carcinogenic mutants.
Indoor uncleanliness, allergenic organisms breeding. The main indoor allergenic organisms are fungi and dust mites. They come mainly from poultry, dust, etc. Fungi have a strong ability to grow, as long as there is a little moisture and organic matter, it can grow. For example, they can grow on glass surfaces, inside household appliances, in cracks in walls, on wooden boards, and even on the plugs of high-grade gasoline canisters in jet airplanes. Dust mites prefer humidity and warmth and grow mainly on dust, mattresses, pillows, sofas and chairs, clothing and food. Both live and dead mites, even their molted skin or feces, are antigenic and can cause asthma or hives.
Patients spread pathogens. Patients with respiratory infections can spread pathogens to others through exhaled breath, sneezing, coughing, sputum and snot.
Indoor supplies
Instruments and equipment used indoors, such as photocopiers and electrostatic precipitators, produce ozone (O3), which is a strong oxidizing agent. It has an irritating effect on the respiratory tract and can especially damage the alveoli.
Home appliances produce electromagnetic radiation. If the intensity of radiation is very high, it can also make people dizzy, salivation, weakness, memory loss.
Indoor dust, burning particulate matter, droplets and other pollutants, and indoor air light ions combined to form heavy ions. The former can only stay in the dirty air for 1 minute, while the latter can stay for 1 hour, which strengthens the adverse effects of heavy positive ions: headaches, heartburn, fatigue, increased blood pressure, depression, loss of concentration, reduced ability to work, insomnia and so on.
Exhaled breath
The main component of exhaled breath is CO2, which averages about 22.6 liters per hour per adult. In addition, accompanying the exhaled can be ammonia, dimethylamine, diethylamine, diethanol, methanol, butane, butene, dibutene, acetic acid, acetone, nitrogen oxides, CO, H2S, phenol, benzene, toluene, CS2 and so on. Of these, most are metabolites in the body, and the other part is pollutants that are still exhaled in their original form after inhalation.
