Abstract:
An environmental assessment system for a method of assessing an oxidative, reductive, or substitution reactivity of a tested environmental region, said system consisting essentially of:a) a sample in aqueous solution or suspension obtained from the tested environmental region;b) a water soluble environmental chemical probe capable of undergoing reduction, oxidation or substitution selected from the group consisting of 1,2-.sup.13 C-chloroacetic acid, 1,2-.sup.13 C-chloroacetamide or 1,2-.sup.13 C-chloroacetonitrile;c) an incubation container for incubating the sample with the probe;d) nuclear magnetic resonance spectrometer for determination of a relative distribution of an oxidative, reductive or substitutive conversion product and an unreacted probe; ande) means for calculating a percentage of conversion of the environmental probe into an oxidative, reductive or substitutive product following the incubation of the sample with the probe and utilizing said percentage of conversion as a measure of the environmental region reactivity.
