Abstract
Heterocyclic aromatic compounds (NSO-HET) have frequently been detected in the environment. Several studies have concluded that NSO-HET pose a threat to organisms in waters, sediments and soils. Consequently, several heterocyclic compounds are under discussion to be included in the priority list of the European Water Framework Directive. However, few publications are available assessing the ecotoxicology of NSO-HET. The present study aims to assess the embryo toxicity of heterocycles using Danio rerio. A combination of the Fish Embryo Toxicity Test and analytical quantification should aid to determine the hazard potential. Changes of the total concentrations due to sorption or volatility were quantified by GC/MS. Loss of compounds during the test was observed primarily for volatile or hydrophobic NSO-HET. The LC50 calculated with nominal concentrations underestimates the toxicity by a factor up to 16 (2 h), demonstrating that a chemical analysis for comparing nominal and measured concentrations is essential for such investigations.
