• Resumen

  • A sensitive Enzime Lynked ImmunoSorbent Assay (ELISA) based on policlonal antibodies wastested in a water sampling exercise at field scale. In the absence of deethylatrazine (DEA), results indicate that the method is useful for the determination of atrazine concentrations ranged between 0 ,1 and 10 pg/l. When compared with gas chromatographic analysis, ELISA over estimatesatrazine concentration. If these tests are used as a semiquantitative screening tool, this tendency for over prediction does not diminish the test's usefulness. The test appears to be a valuable method for monitoring triazine herbicides in water samples from wells and soil water suctioncups.
