Whether adults or children will get leukemia when living in a house with formaldehyde is mainly related to the concentration of formaldehyde.
When the indoor formaldehyde concentration is ≥1.0mg/m³, it can cause cell mutation and the occurrence of leukemia or other cancers, but the exact time how long it takes to develop is not a clear value clinically, and it may take a few days in short cases or months or years in long cases to develop. After inhaling high concentrations of formaldehyde, patients can also irritate the respiratory tract with edema and develop bronchial asthma. Long-term inhalation of a small amount of formaldehyde can cause chronic poisoning, mucous membrane congestion, skin irritation, allergic dermatitis, nail bed finger end pain and other symptoms; and may be accompanied by headache, fatigue, poor appetite, palpitations, insomnia, weight loss and plant nervous disorders and other systemic symptoms.
Therefore, we must test the concentration of formaldehyde in the house before moving in, and make it clear that the concentration of formaldehyde in the air of the living room is less than 0.08mg/m³ before you can move in. At the same time cultivate some plants that can remove formaldehyde, such as hanging orchids, aloe vera, ivy, etc., can effectively reduce the harm of formaldehyde to the human body.
