4 Pharmacology and Biochemistry
4.1 Absorption, Distribution and Excretion

At low concentrations the free acids resulting from the hydrolysis of phosphoryl trichloride will be neutralised quickly by body fluids. The resulting phosphate and chloride ions are natural components of food and ubiquitously found in living tissues and are not expected to pose a hazard. At high concentrations, which exceed the buffer capacity of body fluids the acids will damage the tissue at the portal of entry dependent upon concentration and duration of exposure. A systemic availability of phosphoryl trichloride or the free acids is hence not expected.
