为探讨铅污染对儿童听力的影响，对５０名血铅＞１２０μｇ／Ｌ（高血铅组）和５０名血铅＜１００μｇ／Ｌ（低血铅组）的儿童进行脑干听觉诱发电位（ＢＡＥＰ）测试，结果表明高血铅组、低血铅组的儿童ＢＡＥＰ异常和听阈异常有显著性差异，铅污染对儿童听力可造成一定的影响。 To investigate the effect of lead pollution on children’s hearing, brainstem auditory evoked potentials (BAEP) were measured in 50 children with blood lead> 120μg / L (high blood lead group) and 50 children with blood lead <100μg / L (low blood lead group) ) Test, the results showed that children with high blood lead group, low blood lead BAEP abnormalities and abnormal hearing threshold were significantly different, lead pollution can have a certain impact on children’s hearing.
