Abstract

Agricultural workers rely on chemically protective gloves for protection
from dermal exposure to insecticides. In Australia the most widely used gloves are
manufactured from polyvinyl chloride or nitrile butadiene rubber. During insecticide
application splashes and spills frequently occur on the external surfaces of gloves which
may compromise the integrity of the membrane. Interaction of two organophosphate
insecticides, chlorpyrifos (Lorsban 500 EC®) and diazinon (Jetdip®), with glove
surfaces was investigated in laboratory conditions. The external surface of gloves was
treated with concentrated insecticides for one minute and diluted and concentrated
insecticides for 24, 36 and 48 hours and later examined by environmental scanning
electron microscopy. Two classes of defects, cavities and convexities, were evident in
the polyvinyl chloride gloves following all treatments, whereas cracking was significant
in the nitrile butadiene rubber gloves after 24 hours. In addition, X-ray energy dispersive
microanalysis was used to evaluate chemical changes on the glove surfaces.
Phosphorus and sulfur were useful indicators for organophosphate retention over
specific time frames. Results corroborated the need for more robust chemically
protective gloves to be developed for routine agricultural use.
