2010-2012年陕西蒲城县儿童血铅水平分析

Analysis of 2010-2012 Blood Lead Level of Children in Pueheng County of Shaanxi

目的了解2010~2012年蒲城县O～9岁儿童的血铅水平，为预防儿童铅中毒提供依据。方法用博辉BH2100型原子吸收光谱仪测试，对该院门诊近三年中随意抽取的7000例儿童的末梢血血铅状况进行分析。按2010，2011，2012年和O～2岁，3～5岁，6～9岁及儿童性剐，采用求平均含铅量、中毒率、男女中毒检出率进行分组统计。结果该地儿童平均含铅量和中毒率：按年份为2010年（O．362±0．066μmol／L，11．5％），2011年（0．382±0．075μmol／L，13．1％）和2012年（O．396±0．066μmol／L，16．1％）。按年龄段为0h2岁（0．328±0．065μmol／L，12．3％），3～5岁（0．391±0．074μmol／L，13．2％），6～9岁（0．420±0．069μmol／L，14．9％）。总的含铅水平为0．382±0．069pmol／L，中毒率13．5％。中毒的941例儿童中男童649例，占男生的13．8％；女童292例，占女生的12．7％；男女儿童铅中毒率比较差异无统计学意义（x2=1．75，P〉O．05）。结论该地儿童血铅水平和血铅中毒率随着年龄、年份增加而呈递增趋势；儿童铅中毒率男女差别不大，均应引起人们重视。

objective To understand the blood lead levels of children aged 0-9 years in Pucheng County during 2010-2012, and provides the basis for the prevention of childhood lead poisoning. Methods Using BH2100 atomic absorption spectrom- eter to analyse the peripheral blood lead in 7 000 cases of children in the hospital for recent three years. The obtained data were analyzed statistically according to the 2010,2011,2012 and 0 - 2 years, 3- 5 years, 6 - 9 years old and children~ s gen- der, the average amount of lead poisoning, poisoning rate, and detection rate. Results In the children, the average lead con- tent and poisoning rate were 0. 362±0. 066 μmol/L and 11.5% for 2010,0. 382±0. 075μmol/L and 13.1% for 2011,0. 396 ±0. 066 μmol/L and 16.1% for 2012 by year,and according to the age,0. 328±0. 065 μmol/L and 12.3% for 0-2 years old,0. 391±0. 074 μmol/L and 13.2% for 3-5 years,0. 420±0. 069 μmol/L and 14.9% for 6-9 years old. The total level of lead and -poisoning rate were 0. 382±0. 069 μmol/L and 13.5%. The boy of 941 cases of 941 poisoning children was 649 for 13.8% of the boys,and 292 girls for 12. 7 %. Women and children lead poisoning rate were not significant （x2=1.75, P 〉0.05）. Conclusion The children＇s blood lead level and blood lead poisoning rate with age, year of increasing rate did not differ between men and women. Lead poisoning in children should be paid more attention.
