March 14, the "World Health Organization (who) formaldehyde carcinogenic bulletin" seminar organized by the China Association for science and Technology Engineering Federation, Peking University School of environment, Zhongguancun fresh air industry alliance and other units was held at the International Conference Center of Peking University as scheduled

this symposium, led by the China Association for science and technology, Peking University and other units, brought together more than 30 experts and professors from more than 20 universities and scientific research institutions in the country engaged in many fields such as environment, construction, disease and public health. In response to the Bulletin No. 153 "formaldehyde carcinogenesis" issued by the World Health Organization on June 15, 2004, from China's current indoor formaldehyde pollution sources, pollution hazards, and the mechanism of formaldehyde carcinogenesis, And the indoor formaldehyde pollution control technology that our country has mastered at present

153 "formaldehyde carcinogenesis" bulletin is the result of the review of formaldehyde carcinogenesis by 26 scientists from 10 countries gathered by the international agency for research on cancer (IARC) of the World Health Organization (who). Previously, formaldehyde has been a suspected carcinogen. The IARC expert team pointed out that formaldehyde can not only cause nasal cavity cancer and paranasal sinus cancer, but also has strong but insufficient evidence that it can cause leukemia. At present, the evidence of leukemia is only limited to epidemiological findings, and the carcinogenesis mechanism of leukemia has not been analyzed

Zhu Changshou, a researcher from the industrial hygiene Experimental Institute of the Ministry of health, pointed out in the research report that formaldehyde is widely used in production and life all over the world. At present, the annual output and use of formaldehyde in China is equivalent to that in the United States, but the manufacturer is nearly three times that in the United States. The production scale is small, the process is backward, and the occupational hazards of formaldehyde are also very extensive. Such as the manufacture of plastics and coatings, the production of textiles and industrial chemicals. Common pollution sources include vehicle gas emissions, sandwich panels and similar building materials, carpets, paints and varnishes, food and cooking, tobacco smoke, etc. 8. Displacement measurement error: ± 1% of a large amount of formaldehyde

professor tiandexiang, chairman of the indoor environment professional committee of the Engineering Federation of China Association for science and technology, who has devoted his life to indoor environment research, and the school of environment of Peking University, who must use special materials, introduced in the report that the formaldehyde concentration in the outdoor air is usually relatively low, but the formaldehyde concentration in the indoor air of the family is relatively high. At present, the formaldehyde pollution of sudden fracture in China mainly comes from indoor decoration. In recent years, malignant injury cases caused by formaldehyde, benzene and other organic volatiles in indoor decoration and furniture have occurred frequently in recent years, and have increased year by year, and have developed to a shocking level. According to the data in Professor Tian's report, the annual death toll caused by decoration pollution has reached 111000, about 304 people a day, equivalent to the number of deaths caused by car accidents in the country every day
