Immuno-flourescent technology could possibly give results that are analogous to gas
chromatography, that is, speciation and low level quantification. Further, as more
ELISAs become available for testing atrazine metabolites (an immunoassay that is
specific for desethylatrazine, an atrazine metabolite, is expected to be made available
later this year), there will be more tools for data interpretation.
