Acute toxicity of some hydrazine compounds to salamander larvae, Ambystoma spp
Although hydrazine compounds have been used extensively by industry for a very long time, they have become important in recent years as propellants for aerospace operations. The study of hydrazine compounds in this laboratory began about two decades ago and developed into a large pharmacological and toxicological research program that included also environmental considerations. Subsequently, acute toxicity studies were conducted on the common guppy (Lebistes reticulatus Peters) using four hydrazine compounds of interest. The toxicity of these propellants were evaluated next on other species of aquatic organisms such as mosquito fish (Gambusia affinis) and amphibians. Two different studies were conducted on amphibians: One utilized amphibian eggs and the other amphibian larvae. The larvae of spotted and marbled salamanders (Ambystoma maculatum and A. opacum, respectively) were used primarily in numerous static bioassays to determine the acute toxicity of hydrazine, UDMH and Aerozine-50 on these organisms. The remaining larvae were used in other tests mainly to corroborate previous experimental results (e.g., to see whether toxicity is affected by organism size, aeration of test solutions, and water hardness). The results on the larvae are presented in this paper.
