目的了解辽宁地区成人血铅水平现状。方法采集辽宁省14个城市正常体检人群1 105例,各项检查均正常,无铅接触史,年龄为19~52岁之间,采用原子吸收光谱法测定血铅。结果 1 105例血铅检测结果经统计学分析显示,男女间差异无统计学意义(P>0.05)。根据各地检测结果,最终确定血铅平均范围值为36.87~40.03μg/ml之间,小于血铅标准值(100μg/ml)。1 105例中有35例占3.17%超出100μg/ml标准值,但均小于400μg/ml职业接触限值,总体在正常值范围内。结论沈阳与抚顺血铅高值人相对较其他城市较多,这与城市的工业化程度有很大关系,相对其他城市污染稍高。
Objective To understand the status of blood lead levels in adults in Liaoning Province. Methods A total of 1 105 cases of normal physical examination in 14 cities of Liaoning Province were collected. All the tests were normal and the lead exposure history was between 19 and 52 years old. Blood lead levels were measured by atomic absorption spectrometry. Results 1 105 cases of blood lead test results showed that there was no significant difference between men and women (P> 0.05). According to local test results, the average blood lead level was finally determined to be between 36.87 and 40.03 μg / ml, less than the blood lead level (100 μg / ml). Of the 105 cases, 35 (3.17%) exceeded the standard value of 100 μg / ml, but both were less than 400 μg / ml occupational exposure limits and were generally within the normal range. Conclusions Shenyang and Fushun blood lead high value people are relatively more than other cities, which is closely related to the degree of industrialization of the city and slightly higher than that of other cities.
