Carbofuran Presence in Soil Leachate, Groundwater, and Surface Water in the Potato Growing Area in

by R. Jaramillo, W. Bowen, J. J. Stoorvogel
"... Carbofuran (2,3-dihydro-2,2-dimethyl-7-benzofuranyl methylcarbamate) is a toxic insecticide widely used on potato (Solanum tuberosum L.) crops in Carchi Province, Ecuador. Carbofuran can leach to groundwater and become a threat for both human health and the environment. To determine the extent of ca ..."

of carbofuran presence in the area, we sampled soil leachate, groundwater, and surface water from within 14 hydrologic units (each 2.5–20 ha) where potato was being grown from September to November 1999. Carbofuran was found in all hydrologic units except one, at concentrations that were in-versely proportional
