Spirotox--a new tool for testing the toxicity of volatile compounds.
A new method for estimating the toxicity of volatile compounds was developed. The test was carried out in the disposable polystyrene multiwells. After the organisms, protozoa Spirostomum ambiguum, were added to the wells, microplate was tightly closed using silicone grease and polyethylene film. The toxicities of 21 organic compounds were estimated. No control mortality was observed in all cases. Transparent PE film enabled good observation of test response. The toxicity of tested compounds varied over 4 orders of magnitude. Deformations were 2-4 more sensitive toxic response then lethality. The toxicity of tested compounds in Spirotox test correlates well with the log Kow and toxicity results from other bioassays: Microtox, D. magna and T. pyriformis.
