目的探讨血液、头发微量元素的相关性。方法对2001-12~2004-06在本院儿科住院的1岁~14岁儿童,测定血铅采用火焰原子吸收法,以血铅≥10ug/dl为界限,分低血铅组和高血铅组。用SPSS10软件在联想微机上进行运算数据处理。对结果分别进行统计分析。P<0.05时有统计学差异。结果男204名,女168名。372名儿童血铅水平呈偏正态分布,均数7.98ug/dl,标准差4.1ug/dl,范围最小值3ug/dl,最大值15ug/dl,铅中毒率38·7%,经统计男女性别无显著性差异。血铅水平Ⅰ级228人(61.3%),Ⅱa级132人(35.5%),Ⅱb级12人(3.2%),低血铅组228人,男124人,女104人;高血铅组144人,男80人,女63人,男孩铅中毒率39.2%(80/204),女孩铅中毒率38.1%(64/168),男女间无显著性差异。低血铅组、高血铅组血铅、发铅呈正相关,P<0.05,有显著意义。讨论从本组可见发铅、血铅有很好的相关性,都能反应体内铅负荷水平及钙、锌、铁含量的相关性。说明发铅标本采集处理得当,也不失为一简便的铅筛查方法。
Objective To investigate the correlation between trace elements in blood and hair. Methods Children aged from 1 year to 14 years hospitalized in our pediatric department from December 2001 to June 2004 were determined by flame atomic absorption spectrometry (FCM). The blood lead level was 10ug / dl, group. Using SPSS10 software in Lenovo computer computing data processing. The results were statistically analyzed. P <0.05 was statistically significant. Results of 204 male and female 168. The blood lead levels of 372 children were positively normalized with a mean of 7.98ug / dl, a standard deviation of 4.1ug / dl, a minimum of 3ug / dl, a maximum of 15ug / dl, and a lead poisoning rate of 38.7% No significant gender differences. The blood lead levels were 228 grade I (61.3%), 132 grade IIa (35.5%), 11 grade IIb (3.2%), 228 were low blood lead, 124 were male and 104 were female. There were 80 males and 63 females, with lead poisoning rates of 39.2% (80/204) for boys and 38.1% (64/168) for girls. There was no significant difference between men and women. Low blood lead group, high blood lead group, blood lead, hair lead was positively correlated, P <0.05, significant. Discussion From this group we can see hair lead, blood lead has a good correlation, can reflect the body lead load levels and calcium, zinc, iron content correlation. Description hair lead specimens collected properly, but also after all, a simple lead screening method.
