Objective.
To determine the blood lead levels and identify related risk factors among preschool children in a lead polluted area (Taizhou, China) and provide theoretical support for prevention of lead pollution.
Methods.
A stratified-clustered-random sampling method was used to determine the survey sample.
Blood lead levels were determined by the tungsten atomizer absorption spectrophotometer.
Results.
A total of 2,018 subjects (average age of 59 months; 1,087 boys and 931 girls) were included.
The arithmetic mean, geometric mean, and median blood lead levels of the preschool children were 56.4 μg/L, 48.9 μg/L, and 46 μg/L.
A total of 8.8% children had blood lead levels >100 μg/L and 43.9% had blood lead levels >50 μg/L.
Mother’s education level, father’s occupation, decorative tableware, exposure to makeup, and the residential floor were all risk factors for elevated blood lead levels (odds ratios of 1.42, 1.21, 1.11, 1.19, and 1.27, resp.), while hand washing before eating food was a protective factor (odds ratio of 0.88).
Conclusions.
The blood lead levels of preschool children in Taizhou were higher than in other areas in China and in developed countries.
Therefore, policies ensuring lead-based industries are not placed in close proximity to residential areas are required.
