Primary Outcome Measures :
  1. Concentration of Monohydroxybutenyl Mercapturic Acid (MHBMA) [ Time Frame: 5 days ]

    Concentrations measured on Day 5 in urine, adjusted for creatinine.

    Geometric Least Squares (LS) means are provided as descriptive statistics.


  2. Concentration of 3-hydroxypropylmercapturic Acid (3-HPMA) [ Time Frame: 5 days ]

    Concentrations measured on Day 5 in urine, adjusted for creatinine.

    Geometric Least Squares means are provided as descriptive statistics.


  3. Concentration of S-phenylmercapturic Acid (S-PMA) [ Time Frame: 5 days ]

    Concentrations measured on Day 5 in urine, adjusted for creatinine.

    Geometric Least Squares means are provided as descriptive statistics.


  4. Levels of Carboxyhemoglobin (COHb) [ Time Frame: 5 days ]

    % COHb blood measurements performed in the evening of Day 5, expressed as % of saturation of hemoglobin.

    Geometric Least Squares means are provided as descriptive statistics.
