Abstrakt: The article presents a study that was conducted to compare the effectiveness of cotton gauze with alpha-cellulose pads as the collection media to absorb residues of granular terbufos. In this study, helium was used as a collecting medium. The t-test showed that the amount of terbufos found in alpha-cellulose pads was significantly more than that found in cotton gauze. Researchers stated that this difference in the amount of pesticide absorbed by alpha-cellulose and cotton gauze is likely due to the different surface characteristics and structure of the two materials. The surface of alpha-cellulose is smoother and its structure is more compact than that of cotton gauze.
