A procedure for the measurement of halothane in the breathing zone of operating theatre personnel is described. This is achieved by sampling air through a U-tube containing silica gel. Concentrations found in operating theatres ranged from less than 0·1 to 8 ppm. The method can be used to evaluate exposure over a full working day.
