A toxic-monitoring material for the detecting and monitoring of toxic fluids placed in contact with or exposed to the monitoring material, which material comprises a solid, microporous, transparent, polymeric, matrix material having interconnecting micropores filled with a liquid composition, the liquid composition comprising a solvent for the toxic component to be detected and a reactant which reacts with the toxic component, whereby a toxic component dissolves in the solvent within the micropores and reacts with the reactant, to produce a change in color or appearance throughout the depth of the material, so that the detecting and monitoring of the toxic fluid may be determined.
