The Canadian research analyzed soil and water samples at nine sites where military explosives were detonated between 1990 and 2014, and came up with data about where and in what concentrations the explosive compound known as RDX, a possible human carcinogen, had turned up. Calling RDX “an internationally known problem,” which “has led to an international warning on possible soil, surface water, and groundwater contamination on military training sites,” the research described with actual measurements how RDX floats on the wind and seeps through soils into water supplies.
EPs are recordings of the nervous system’s electrical response to the stimulation of specific sensory pathways (., visual, auditory, general sensory). In tests of evoked potentials, a person’s recorded responses are displayed on an oscilloscope and analyzed on a computer that allows comparison with normal response times. Demyelination results in a slowing of response time. EPs can demonstrate lesions along specific nerve pathways whether or not the lesions are producing symptoms, thus making this test useful in confirming the diagnosis of MS. Visual evoked potentials are considered the most useful in MS.
