title: [Investigation of the arsenic levels in ecosystem aspect in water type of endemic arsenicosis area in Datong City].
abstract: OBJECTIVE
  To investigate the arsenic levels in endemic arsenism in Datong City, Shanxi Province.
  
  
  METHODS
  A total of 85 inhabitants from one village in endemic arsenism area in Datong City, Shanxi Province were collected as research subjects. The People's Republic of China health industry standard for endemic arsenism was used to identify and diagnosis the patients. Daily drinking water and soil were collected and detected by atomic fluorescence spectrometry. The content of vegetables were detected by inductively coupled plasma mass spectrometry (ICP-MS).
  
  
  RESULTS
  In the study, 85 samples were collected. Arsenic concentration in the daily drinking water were 14.41 - 90.34 μg/L, and the median value was 43.88 μg/L. The arsenic concentration of vegetables were 0.001 - 0.771 mg/kg, and 43.04% of samples, were higher than the maximal permissible limit of As in food. The results that the arsenic concentration of vegetables constant changes in the leaf vegetables > tubers > fruit vegetables. The health risk of intaking arsenic pollution in vegetables up to 71.77%. The arsenic levels in village of four directions were not exceeded the Chinese standards.
  
  
  CONCLUSIONS
  Arsenic concentration in drinking water and vegetables are high in waterborn endemic arsenicosis area of Shanxi province. Arsenic in drinking water has been considered as a primary cause of arsenism, but direct intake of arsenic from vegetables can not be ignored.
