El objetivo del presente trabajo fue evaluar, a través de ensayos crónicos de 21 días, los efectos de cuatro formulaciones comerciales deglifosato (Eskoba® (Red Surcos), Panzer Gold® (Dow Agrosciences),Sulfosato Touchdown® (Syngenta Agro) y Roundup Ultramax® (Monsanto)) sobre atributos de historia de vida y el parámetro poblacionalR o de Daphnia magna y Ceriodaphnia dubia. La fecundidad fue el atri-buto más afectado en las dos especies. Se registraron alteracionesen el ciclo de vida por la producción de huevos abortados y efipiosen D. magna expuestos a 0,15 y 0,62 mg e.a L -1 de Panzer Gold®. Además, a 0,1 y 0,31 mg e.a L -1 de los dos formulados de mayor toxicidad(Sulfosato Touchdown® y Panzer Gold®), Ro para las dos especies decladóceros fue <1, condición que indicaría una disminución pobla-cional y posible extinción local en los ambientes perturbados por losherbicidas evaluados. Se destaca la importancia de profundizar elconocimiento de los efectos subletales de formulaciones que tienenal glifosato como principio activo, mediante el análisis de componen-tes clave del ciclo de vida de las especies acuáticas.

Abstract In Canada, effluents from pulp and paper mills are regulated for toxicity. The regulation requires ≥50% survival of rainbow trout (Oncorhynchus mykiss) exposed to full-strength (i.e., 100%) effluent for 96 h in tests that must be conducted monthly. The regulation also calls for ≥50% survival of Daphnia magna exposed to 100% effluent for 48 h in weekly monitoring tests. Every year, about 10 to 25% of the mills exceed the regulatory limit at least once in tests with either rainbow trout or Daphnia magna. Between 1996 and 2003, we investigated 84 such cases from 32 mills. Of the 84 investigations, 49 involved only trout, 29 involved only Daphnia, and six involved both species. We identified the actual cause of toxicity in 70% of the cases and partially or tentatively identified the toxicant(s) in 17% more. In the cases involving only trout, the most frequent causes of toxicity were related to biotreatment performance (e.g., ammonia). In the cases involving only Daphnia, the most frequent cause of toxicity seemed to be related to polymeric formulations. For those cases involving both trout and Daphnia, the cause of toxicity was traced to more than one compound or to excess concentrations of a specific compound resulting from a spill or biotreatment-related problems.
