According to China epidemiologic statistics,the natural incidence of leukemia nationwide is 3 out of 100,000 people, and 40,000 people are diagnosed with leukemia every year, 50% of which are children, mainly aged1 from 2 to 7 years old.
Officials with China Indoor Environment Monitoring Committee suggest that children living in areas of high formaldehyde air are at increased risk of developing leukemia, because there is a possible association between formaldehyde pollutants2 and the incidence of children leukemia.
Data from Beijing Children's Hospital indicate that over 90 % of urban children diagnosed with leukemia have their houses decorated no more than half a year ago.
Similar data results have been shown by Shenzhen Children's Hospital.
