An ultra‐violet absorption method for the determination of mercury vapour in air is described. The apparatus incorporates a special ultra‐violet filter. The amount of mercury vapour sorbed by clean pyrex glass was found to be small compared with that sorbed by wheat, and to have no relation to the time of exposure. The sorption of mercury vapour by English wheat of moisture content 13–18% at temperatures of 20–30°C. has been studied. It is concluded that most of the mercury sorbed is firmly retained by reaction with the wheat tissues.
