      <subfield code="a">Atmospheres of silicon carbide whiskers (wh) were required for a repeated dose lung deposition study and a subchronic inhalation toxicity study, each involving exposure to three concentrations of whiskers for 6 hr/day, 5 days/week for 1 or 13 weeks. Chamber atmospheres were characterized gravimetrically and samples were analyzed by scanning electron microscopy</subfield>
