      <subfield code="a">The analysis of urine, blood, and hair has been used previously to monitor occupational exposure to arsenic. Although arsenic is normally present in human fingernails, this study evaluated the potential use of levels of arsenic in fingernails as a biological indicator of occupational exposure to this element. Air samples and fingernails clippings were obtained from individuals with no exposure and high, medium, and low exposure</subfield>
