“…This fi nding is consistent with that of Zhang et al's study, which involved 14 Chinese cities in [2004][2005][2006]. (16) However, the 2007-2010 data from the present study and a previous study (20) yielded different results; the data obtained during that period showed no signifi cant difference in the BLLs of boys and girls. This may be due to population mobility or sampling error.…”

“…(15) In recent years, lead exposure has received serious attention from Chinese scientists, and since 2004, the Child Hygiene Cooperation Center of the World Health Organization (WHO) in China has been carrying out investigations to monitor the BLLs of children from 14 Chinese cities. (16) One study conducted in China reported that lead poisoning has affected more than 4,000 children in several Chinese cities and that the BLLs of most of the affected children were > 25 μg/dL. (17) Such fi ndings indicate that there is a need for large, population-based investigations to objectively assess BLLs and that practical guidelines for the prevention and treatment of childhood lead poisoning should be developed.…”

RESULTSThe mean BLL of the 2,271 children was 6.2 μg/dL and 2.03% of the children had BLLs ≥ 10 μg/dL. Mean BLL seemed to increase with age. Unhygienic habits (e.g. not washing hands frequently, biting of toys and pencils), history of pica, use of coal and residence in an industrial zone were found to be the main risk factors contributing to high BLL (p < 0.05). Children with high BLLs have a higher risk of manifesting anorexia and/or abdominal pain as compared to those with low BLLs (p < 0.05). CONCLUSIONThe mean BLL of children in Chengdu (i.e. 6.2 μg/dL) was found to be higher than that of children in developed countries. Childhood lead poisoning remains a public health problem.

Lead poisoning is one of the most significant environmental health threats which children face. The aim of the study was to evaluate the relationship between the blood lead level (BLL) of children and environmental pollution, as well as the effect of BLL on children's heath, in the biggest city in south-west China. A questionnaire survey was administered to 3,624 children's (6 months-7 years old) guardian in urban Chengdu from 2007 to 2009, collecting data on inhabited environment, living habits, and health status. All blood samples were collected for BLL test when the children came to the hospital. The analysis was conducted in West China Second University Hospital, Chengdu, China in December, 2009. A total of 3,624 children were included. The mean BLL was 62.31 μg/L. Three hundred thirty-three (9.2%) of 3,624 children's BLL were above 100 μg/L. Taking Chinese medicinal herbs usually, puffed foods, and substitutes of breast milk were risk factors (P < 0.05).The study shows that Chinese children's lead poisoning prevention and treatment lags far behind developed countries. The findings have implications for environmental health policy.
