Manual práctico de ensayos de toxicidad en medio acuático con organismos del género Daphnia
Sinopsis
Los ensayos de toxicidad son pruebas diseñadas para evaluar la potencia relativa de un agente o una sustancia contaminante sobre una o más especies de organismos de los sistemas biológicos acuáticos y terrestres, al tiempo que permiten caracterizar la relación concentración-respuesta entre el agente contaminante y el organismo sometido a prueba. La toxicidad de una sustancia es la propiedad que tiene de causar daños a la salud humana o la muerte de un organismo vivo, mediante la comparación de efecto del agente con el de una solución patrón o estándar.Los resultados de las pruebas de toxicidad en sistemas acuáticos constituyen un criterio importante para determinar el efecto y el riesgo de la descarga de sustancias contaminantes sobre los ecosistemas acuáticos, así como para establecer valores límites permisibles para el control de sustancias tóxicas que son incorporadas a los ecosistemas acuáticos.Con la euge de la ecotoxicología ciencia que predice de los agentes potencialmente tóxicos en los ecosistemas naturales (Hoffman, 1995) se ha reforzado la idea de realizar monitoreos y pruebas de toxicidad para la detección, predicción y control de los efectos de diferentes tipos de sustancias sobre los ecosistemas, en particular, el acuático.
