I have a spatial data set that has Immunoassay screening test results for TNT
and other nitroaromatic explosives in soil. The screening data is
left-censored at 20 or 100 (depending on the dilution of the test solution) and
right censored at 975. The screening data is in the form of a score because I
don't regard it as a good measure of chemical concentration. I have used the
immunoassay score for a soil sample and the presence of red staining
(characteristic of TNT) in the area in which that soil sample was taken as
predictors to construct a quasi-likelihood model of the probability that a
laboratory analysis of the soil sample would give a result greater than or
equal to 190 mg/kg TNT. The TNT concentration 190 mg/kg is the risk-based
cleanup goal for this site.
If you are interested, I may be able to make this data set available, but I
will have to get the permission of the Army. This shouldn't be problem but it
may take a couple of weeks at least.
