ABSTRACT
Introduction: GF is a chemical nerve agent that is a fl uoride-containing organophosphate. It is a slightly volatile liquid that is almost insoluble in water. GF enters the body primarily through the respiratory tract, but is also highly toxic through the skin and digestive track. It is a strong cholinesterase inhibitor. It is approximately twenty times more persistent than sarin (CB). GF is about as persistent as tabun, and evaporates about twenty times more slowly than water. Heavily splashed liquids persist one to two days under average weather conditions. It is a quick action casualty agent, and is very stable.
