碩士 === 輔仁大學 === 公共衛生學系碩士班 === 101 === The permeation of the chemicals through chemical protective gloves are affected by the chemicals’ physical and chemical characteristics, such as molecular size (molar volume, MV), polarity (logKow) and etc. In this study, the molar volume (MV) and logKow of chemicals were selected as the independent parameters to predict the permeation behaviors of different protective gloves. Permeation parameters, (breakthrough time, BT and permeation rate, PR) were obtained from the manufactures – Ansell, North and Medical Exam Glove. SPSS was utilized to perform the regression analysis between the chemical physical and chemical parameters and the permeation parameters. The results indicated that MV and logKow were the significant factors in predicting the permeation behaviors of different gloves by different manufactures. Significant correlation was found between BT and logKow, the regression result of non-polar compounds (logKow > 0) was BT = 19.718 + 70.637logKow (r2 = 0.374, p = 0.001) for Ansell Neoprene/Natural Rubber Blend gloves. For North Viton gloves, the regression result was BT = 4.032 + 1.419logKow (r2 = 0.190, p = 0.002). BTs of North Nitrile gloves were significantly associated with MVs for non-polar chemicals with a linear relationship, BT = -0.779 + 1.285MV (r2 = 0.198, p = 0.014). All these suggest that a hydrophobic chemical or a chemical with big molecule tends to break through the glove material slowly.
