    Los herbicidas se usan para aumentar el rendimiento decultivos y pastos. El herbicida 2, 4-D tiene un alto potencial de lixiviación enambientes cársticos por ser soluble en agua, lo que provoca que el herbicidahaya sido detectado en agua subterránea y cuevas en la Península deYucatán. En esta nota presentamos resultados de la detección del herbicidaen el agua subterránea en zona agrícola y no agrícola en el noreste dela península de Yucatán mediante el uso de espectro UV obtenido conequipo HPLC-DAD como indicador cualitativo de su presencia en el acuífero.Este hallazgo respalda la idea de que la aplicación de 2, 4-D antes ydurante la estación de lluvias fomenta la presencia del herbicida en el aguasubterránea.

    Herbicides are used to increase the yield of crops and pastures.The herbicide 2, 4-D has high leaching potential in karstic environmentsbecause it is water soluble, which causes that the herbicide has been foundin groundwater and submerged caves in the Yucatan Peninsula. We detectedthe presence of the herbicide in groundwater in agricultural non-agriculturalzones in the northeaster of the Yucatán Peninsula by using the UV spectrumobtained from HPLC-DAD as qualitative indicator. This finding supports thenotion that application of 2, 4-D before and during the wet season promotesthe presence of the herbicide in groundwater.
