摘要
目的了解某废旧电池回收加工企业周边居民血铅浓度水平。方法于2016年12月,在某废旧电池回收加工企业周边选择1个行政村作为暴露区,同时,选择距离7 km的1个行政村作为对照区,采集2~14岁儿童和15岁以上居民血液样本,采用《血中铅、镉的石墨炉原子吸收光谱测定方法》测定血铅浓度。共采集379份血样。结果暴露区和对照区儿童血铅浓度检出范围分别为28.62~485.01、19.32~89.32μg/L,几何均值则分别为91.30、44.18μg/L。暴露区和对照区成人血铅浓度检出范围分别为6.00~1 066.57、6.00~175.71μg/L,几何均值分别为76.68、51.16μg/L。暴露区儿童和成人血铅浓度均高于对照区(P<0.05)。暴露区儿童和成人血铅浓度异常率分别为33.7%和2.4%;对照区则均未出现异常。在暴露区,儿童和成人男性血铅浓度均高于女性,差异有统计学意义(P<0.05);在对照区,仅在成人表现为男性高于女性(P<0.05)。结论该回收加工企业生产造成的铅污染已导致周边居民尤其是儿童血铅负荷显著增加。
Objective To know blood lead levels of residents living around a waste battery recycling and processing enterprise（WBRPE）. Methods In 2016,one administrative village around a WBRPE was selected as exposure area,another 7 km far from WBRPE as control area.A total of 379 blood samples were collected from children aged 2-14 and adults aged 〉15 for determination of lead. Results Higher blood lead levels were found in children（G：91.30 μg/L, range：28.62-485.01 μg/L） and adults（G：76.68 μg/L, range：6.00-1 066.57 μg/L） in polluted area,lower levels in control area（Gchildren：44.18 μg/L;rangechildren：19.32-89.32 μg/L;Gadults：51.16 μg/L;rangeadults：6.00-175.71 μg/L） respectively,regional differences was significant（P〈0.05）.The abnormal rates of blood lead were 33.7% and 2.4% for children and adults in polluted area respectively, while there was no abnormal case in control area.Higher blood lead levels were found in male among children and adults in polluted area（ P〈0.05）,and only in adults in control area（P〈0.05）. Conclusion The WBRPE-induced lead pollution causes higher blood lead level for residents living around,especially for children.
