The Effects of Solvent Type and Concentration on the Permeation of Pesticide Formulations Through Chemical Protective Glove Materials

Résumé du livre

A modified ASTM F 739-85 test method has been developed which permits the collection and analysis of both volatile and non-volatile, low aqueous solubility compounds from mixtures which permeate protective clothing materials. Permeation tests have been conducted using eleven pesticide formulations containing a range of active ingredient and carrier solvent types and concentrations. Nitrile, natural rubber, and neoprene glove materials were tested in every case; PVC., polyethylene and butyl glove materials were examined in selected instances. Both carrier solvent and active ingredient permeation were measured over the eight-hour test period. Carrier solvent concentration was found to have the most effect on the permeation resistance of glove materials. Xylene range aromatic solvents were most dramatic in decreasing the breakthrough times of both carrier solvent and active ingredient and in increasing the cumulative amounts of permeants measured.
