2. Activated carbon adsorption method is the most widely used method to remove these harmful gases by using activated carbon and bamboo charcoal with adsorption function.
3. Plant decontamination can choose medium and low pollution: generally, in the environment where indoor environmental pollution is light and moderate, and the pollution value is less than 3 times of the national standard, plant decontamination can achieve better results. Indoor formaldehyde can be adsorbed by plants with adsorption function, such as chlorophytum, Hupilan, ivy, aloe, agave and gerbera, so as to be removed.
Extended data:
1, one of the concrete manifestations of formaldehyde poisoning symptoms:
Mild poisoning-eye and upper respiratory tract mucous membrane irritation symptoms are obvious. The main manifestations are conjunctival congestion, redness, dyspnea, heavy breathing, hoarse throat, dry or dull speech or wet greasy. When X-ray is taken, the lung texture increases and thickens, which is a typical symptom of acute bronchitis in medicine. Another specific symptom of mild formaldehyde poisoning is one to two degrees of throat edema.
2. The second concrete manifestation of symptoms of formaldehyde poisoning:
Moderate poisoning-persistent cough, expectoration, chest tightness, dyspnea and dry and wet gongs. During chest X-ray, the lung texture becomes substantial, becoming scattered spots or flaky shadows, which is medical machine-made bronchopneumonia. The edema of throat is aggravated to grade three. Blood gas analysis will be accompanied by mild and moderate hypoxemia.
