Lead level of the soil and crops on the highway-sides (pollution area)and the area far away from the highway (control area) was determined. The basic situation was investigated by the questionnaire, the blood lead level was determined by graphite furnace atomic absorption spectrometry. The influence of lead on children's intelligence, physical growth and the influencing factors for blood lead level were analyzed. Results The average lead level of the soil [(96.89?15.05) mg/kg] and crops [(0.86?0.29) mg/kg] in the polluted area was significantly higher compared with the control [soil lead: (29.83?1.41)mg/kg,crops lead:(0.17?0.03) mg/kg], and revealed statistical significance respectively (P
