Resumen:
Abstract. The Pampa plain is intensively cultivated, the genetically modified glyphosate-resistant soybean being the main culture. A small first-order stream draining a cultured farm was studied. During the dry 2007 spring, the channel became a wetland with remnant intercalated shallow pools. Toxicity persistence of cypermethrin and chlorpyrifos to the amphipod Hyallela curvispina was assessed following a simulated plane application in the recently formed pools. In situ exposures and laboratory toxicity tests were performed. An ephemeral toxicity pulse lasting 4 h after the application and mortality cessation following that was observed.
