Abstract

Objective To conduct a survey to evaluate the serum levels of lead in children living in Guangzhou area,2009.Methods The concentration of lead was determined using the Tungster atomizer absorption spectrophotometer.37 318 children blood samples from the Guangzhou Women and Children's Medical Center in 2009 were tested.The mean lead level and the rate of lead poisoning were analyzed.Results The mean blood lead level was 47.55 μg /L,and the range of lead concentration was from≥100 μg /L(2.91%),200～249 μg /L(0.26%),250～449 μg /L(0.28%),to450 μg /L(0.035%).The level of lead content in boys(49.37 μg /L) was higher than girls(44.28 μg /L).Conclusion There are a tendency of decreasing in the level of lead in blood of children living in Guangzhou.
