  1. aSum of AsIII and AsV was determined by high-performance liquid chromatography coupled with inductively coupled plasma mass spectrometer spectrometry (HPLC–ICP-MS)
  2. bTotal arsenic was determined using ICP-MS after digestion
  3. cRatio of AsIII + AsV to total arsenic
  4. dData are represented as mean value ± standard deviation (n = 34)
