초록

To determine their acute toxicities on the earthworm (Eisenia fetida), six toxic chemicals were evaluated, according to the OECD guideline 207: sulfuric acid, methanol, methylethylketone, nitric acid, formic acid, and toluene. Sulfuric acid exhibited the maximum toxicity. The LC50 values of sulfuric acid, nitric acid, formic acid, and toluene were 20.5, 49.1, 55.5, and 534.5 μg cm-2, respectively. Toluene showed 26-fold lower toxicity than sulfuric acid. In this study, methanol and methylethylketone did not exhibit any toxicity to the earthworm. Further evaluation revealed that nitric acid, formic acid, and toluene exerted a change in the body weight of the chemically treated earthworms, whereas the other chemicals were ineffective. These results can be used for environmental risk assessment, when the chemicals are accidently discharged into the environment.
