Respuesta de la diatomea Thalassiosira rotula (Meunier, 1910) a los bifenilos policlorados. Implicaciones metodológicas

Abstract

[ES] Se expusieron poblaciones de Thalassiosira rotula en crecimiento exponencial, a 20, 50, 100 y 200 ng/ml (ppb) del A-1232 y a 5, 10, 25 y 50 ng/ml (ppb) del A-1248. La DI del A-1232 resultó ser de 71 ppb, mientras que la DI del A-1248 fue de 20 ppb. Los resultados experimentales muestran que dichas dosis varían a lo largo del tiempo de incubación; asimismo se refleja una relación directa entre toxicidad y grado medio de cloración.

[EN] Cultures of Thalassiosira rotula, in exponential growth, were exposed to 20, 50, 100 and 200 ng/ml (ppb) of A-1232 and to 5, 10, 25 and 50 ng/ml (ppb) of A-1248. The ID of A-1232 was estimated to be 71 ppb, while ID of A-1248 was of 20 ppb. Esperimental results show that these doses vary throughout the period of incubation; likewise there is a direct relation between toxicity and mean degree of chlorination.
