Analysis of the test results of 2850 children's blood lead

Objective To investigate children′s blood lead levels,and provide a scientific basis for the prevention and treatment of lead poisoning in children.Methods The blood 1ead concentrations of 2 850 children from pediatric outpatient clinic were determined using atomic absorption spectrophotometer from August 2011 to October 2012.Results Among the 2 850 children,the blood lead poisoning rate in different age groups was 2.67%,2.74%,3.12% and 3.15%,respectively.The lead poisoning rate was increasing slightly along with the age growth.There were no statistical differences among different age groups(χ2=-0.15,P0.05).There were 2 769 cases with blood lead concentration 100 μg/L,81 cases of blood lead mild poisoning,with a lead poisoning incidence of 2.85%.The differences had statistical significance(χ2=10.15,P0.05).Conclusion The blood lead levels are increasing with age;the lead poisoning ratio in boys is higher than in girls.Early detection,diagnosis and treatment are suggested in order to ensure the health and growth of children.
