Mr Li, who couldn't get back to shenlai in a few days, couldn't believe the doctor's words, so he took his child to Jiangsu Provincial People's hospital After examining the child, the doctor said that the child only had a low content of some component in the blood and did not suffer from leukemia After learning that Mr Li's house has just been decorated, the doctor suggested that Mr Li should find relevant departments to test the decorated house, and said that the child's illness may be related to the house decoration After testing, the methanol and benzene in Mr Li's house slightly exceeded the standard In order not to let the children suffer again, Mr Li's family still dare not live in the newly decorated house The harm of indoor decoration pollution to people and the loss caused by it have attracted the attention of the relevant departments of the state On March 1, 2003, the first indoor air quality standard in China was officially implemented According to the data released by the Ministry of construction and the China Consumer Association, the number of complaints about housing sales and decoration reached 12000 a month in 2004 In the same period, the number of deaths caused by indoor air pollution in China has reached 111000 every year, about 304 per day, which is equivalent to the number of deaths caused by car accidents every day Among these patients, children become the most threatened group in decoration pollution Benzene and formaldehyde may cause leukemia Yesterday, the reporter learned from Nanjing Children's hospital that in recent years, the number of children with leukemia has increased significantly Most of the leukemia patients who come to the hospital every year have been decorated within half a year According to experts from the hospital, some children suffer from diseases due to careless exposure to chemicals, and others suffer from thrombocytopenia due to buying new furniture at home that fails to meet environmental protection requirements After summing up, experts in children's medicine speculated that the indoor environmental pollution caused by improper decoration was an inducement for the obvious increase of leukemia patients in children in recent years Li, director of Hematology Department of Jiangsu Provincial People's Hospital, also said that the biggest inducement of leukemia is radiation and pollution Benzene and formaldehyde in indoor pollutants are indeed related to the incidence of leukemia, while the probability of inducing leukemia by virus factors and genetic defects is far less than benzene and formaldehyde What harm does benzene and formaldehyde do to human body?
