【Objective】 To explore the relationship between children with attention deficit hyperactivity disorder(ADHD) and their blood lead,zinc and ferrum levels. 【Method】 Blood lead,zinc and ferrum levels of 70 ADHD children and 60 healthy controls were determined by atomic absorption spectrometry. 【Results】 The blood zinc and ferrum levels [(74.39±10.71)μmol/L,(8.52±0.58)mmol/L] were lower in ADHD children,than those in health controls [(80.60±9.07)μmol/L,(8.76±0.51)mmol/L,t=3.538 or 2.536,P0.01 or 0.05].The blood lead level [(57.3±20.9)μg/L] was higher in ADHD children than that in health controls [(45.9±17.4)μg/L,t=3.357,P0.01]. 【Conclusion】 Blood lead is high and zinc and ferrum is deficient in some ADHD children,which should be determined routinely and retrieved as soon as possible.
