• To investigate the blood lead level of children living around lead-zinc mining areas, in order to analyze its distribution features of the population.

The distribution features of blood lead in different district, gender and age groups were compared and analyzed. The median and quartile range of blood lead were 0.066 and 0.058 mg/L respectively. The blood lead levels of 341 children were esceeding 100 μg/L and that account for 24.73%. The median blood lead showed statistical significant differrnce among three groups ( <0.01) , and the medians from high to low w
