To estimate blood lead levels of 0～6 years old children in Zhuhai, and to identify high-risk factors for lead poisoning of children. The blood lead levels and the related factors of all involved children were investigated in Zhuhai, using an epidemiological survey with sophisticated quality control. The mean of blood lead level was 182.08μg/L(1μg/L=0.004 83μmol/L)and 419 children (77.6%) were found with a blood lead level≥100μg/L.Blood lead level varied with geographic locations.The highest mean of blood lead level (193.54μg/L) was found in children from Doumen country, and the lowest (160.87μg/L) was found in children from island. There was statistically significant difference between the tow regions. [Conclusions] Blood lead levels of children in Zhuhai and the prevalence of lead poisoning were both relatively high, to which enough attention should be paid.
