The volumetric pollen-spore trap

11 Mr. Sc Thesis Kemal ÇETİN GAZI UNIVERSITY INSTITUE OF SCIENCE AND TECHNOLOGY January, 1997 ABSTRACT This study aimed the design, manufacturing and application of a volumetric pollen-spore trap. In this study; Burkard volumetric spore trap had been taken as a reference and modified. The difference between our system and the reference is that the movement of disc rotation mechanism had been provided by a DC motor. The system marked an example that during 7 days period it absorbed 10 It. air per minute at the disc which was turned in a 2 mm/hr speed. Compared to the reference system, the system designed had been gained 0.5 mm/hr. - 8 mm/hr. average disc speed. This modification had been realized by supplementary electric fan unit. 7- days period trials hade been made, and all data taken were evaluated. The experimental results revealed that the system designed and manufactured is fully functional. Science code Key words Pollen, spore, spore trap, Burkard 52 Prof. Sevil PEHLİVAN
