In September, 2012, 20 ton of hydrofluoric acid is leaked in Gumi province, Korea where neutralizing agent is spread after passing 15 hours. Under this situation, the present invention relates to an experiment to check whether the soil of Gumi is proper for plant growth or not, after leaking hydrofluoric acid, and how many types and numbers of germs live by distances from the accident place. Also, in the present invention, soil conditions of Texas, where hydrochloric acid is leaked in the same year, is checked according to the exposure of hydrochloric acid. In the present invention, plants neutralized and raised in the accident plate, Korea have too thin stems and too small roots, and the soil exposed to hydrochloric acid and hydrofluoric acid has fewer types and numbers of germs by elapsed time but has a fewer number of filamentous fungi like Eumycetes than that of a control group. |
