    Notes: Summary Reference is made to a procedure for evaluating certain incidental findings presented by particles of soot or dust on the adhesive strips of the Burkard pollen-and-spore trap or the slides of the similar Hirst apparatus. For this an evaluating device is recommended that is generally used for pherograms in large hospitals today. The often very noticeable streaks of soot or dust particles on the adhesive layer can be assessed with this method. Furthermore, it is possible to determine the time of the occurrence of the particles and possibly to relate them to the velocity and direction of the wind, and also eventually to detect the source of the polluting material.
