Abstract:The acute toxicity of N-nitrosodimethylamine (DMN) and N-nitrosodiethylamine (DEN) was determined for three groups of aquatic organisms: algae, invertebrates, and fish. Toxicity of DMN and DEN to algae was assessed as a repression in the growth rate of either Selenastrum capricornutum or Anabaena flos-aquae in static bioassay tests. DMN and DEN concentrations of 1-10 ppm depressed algal growth in all cases. Invertebrate toxicity was determined in 96-h static bioassay tests with Dugesia dorotocephala and Gammar… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
