    The aim of this work was to measure the permeation of the active ingredient in selected pesticidal formulations through specific glove materials and clothing. Pesticides used included 1,2- and 1,3-dichlorobenzene and Esteron 99 containing the isooctyl ester of (2,4-dichlorophenoxy)acetic acid (2,4-D), in an ASTM type permeation cell using a liquid collection system and flame ionization (for the dichlorobenzenes) and electron capture (for the 2,4-D ester) detectors after gas chromatography. The materials examined included Tyvek, Viton, Nitrile and Neoprene. The choice of glove materials was based on the characteristics for chemical analogs for the 2,4-D ester since no permeation data exist for herbicidal formulations. Breakthrough and steady state rates were calculated. Pinhole penetration occurred but especially in lined Nitrile and Neoprene gloves. Cosolvent effects were important. Viton protected better against the dichlorobenzenes than did Nitrile with the supported/lined gloves being least protective. Tyvek and unsupported/ unlined Nitrile protected best against the 2,4-D formulation in challenges against the formulation concentrate and a diluted aqueous emulsion solution.
