According to a large number of studies on indoor formaldehyde pollution to human health, many scholars at home and abroad put forward that formaldehyde has obvious effects on respiratory system and immune system and is carcinogenic.
Although formaldehyde pollution in indoor air has a certain relationship with leukemia, IARC even thinks that some evidence is strong, but there is still not enough evidence to prove that there is a causal relationship between them. The biological mechanism of whether formaldehyde can cause leukemia needs further study.
Extended data
The causes of leukemia are very complicated-environmental pollution, gene mutation, electromagnetic radiation, viruses and so on. Limited by the current research level, it is difficult for scientists to accurately judge the cause of a specific leukemia patient, which is one of the reasons why leukemia is difficult to be overcome.
Existing research shows that indoor formaldehyde pollution is related to leukemia, but there is still no evidence-based medical evidence. Therefore, at present, it cannot be proved that "formaldehyde pollution causes leukemia", but this possibility cannot be ruled out.
The review article "Research Progress on the Relationship between Air Pollution and the Risk of Acute Leukemia in Children" published by Shanghai Jiaotong University Medical Edition 20 15 quoted relevant papers as saying that formaldehyde is a gas with strong pungent odor and one of the normal metabolites of human body. The International Agency for Research on Cancer (IARC) lists formaldehyde as a first-class carcinogen, and believes that formaldehyde has a high risk of causing nasopharyngeal carcinoma.
