title: [Lead exposure of people living in a lead high exposure area from local diet].
abstract: OBJECTIVE
  To study the lead exposure of people living in a lead high exposure area from local diet, and to assess its health risks.
  
  
  METHODS
  Thirty five subjects were selected by random from a mining area and another 30 subjects were selected from a non-polluted area. The exposure of lead was estimated by the content of lead in drinking water and vegetables, and health risks was estimated by the levels of lead in blood and urine.
  
  
  RESULTS
  The content of lead in drinking water and vegetables in the mining area was 20.6 microg/L and 1.61mg/kg (geometric mean) respectively, which were higher than that in the unpolluted area (6.0 microg/L and 0.56 mg/kg, geometric mean) (P < 0.01). The daily lead exposure of male and female inhabitants in the mining area from diet was 16.88 microg/kg and 16.09 microg/kg respectively, which was higher than that in the unpolluted area (P < 0.01), but the sex difference was not significant statistically (P > 0.05). Blood lead and urine lead of inhabitants in the mining-area were higher than those in the unpolluted area. The health risks for male and female inhabitants in the mining area were 4.73 and 4.51.
  
  
  CONCLUSIONS
  The health risks of lead exposure caused by diet (drinking water and food) were relatively high in the mining area.
