Full life-cycle toxicity assessment using rotifer resting egg production: implications for ecological risk assessment

摘要

The majority of standardized toxicity tests incorporate only a fraction of the test organism's life-cycle. However, in natural eco- systems, organisms may be exposed at various times during their life-cycle or throughout their life-cycle. Thus, ecotoxicological data from standardized toxicity tests is of limited ecological relevance. Existing standardized toxicity test using the freshwater rotifer Brachionus calyciflorus utilize 24-h survival or 48-h asexual reproduction as endpoints, despite evidence that sexual repro- duction is more sensitive.
