Abstract: | Glutaraldehyde is a volatile and irritate chemical. It may be get into human body by mouth, by skin or by inhalation, and results in the body harm, or results in the fish death when its liquid waste is discharged into Rivers. This study assayed the acute toxicity of glutaraldehyde by the three exposure routes of body, and assayed fish acute toxicity. The results show that the LD50 ( or LC50 ) is 248 mg/kgbw( mice, by mouth), 239 mg/kgbw( rat, by mouth), ≥2000mg/kgbw (rat, by skin), 768mg/m3 ( mice, by inhalation) and 13. 5mg/L (fish, 96h - LC50. ). According to the acute toxicity grades, the acute toxicity of Glutaraldehyde by mouth, by inhalation and the fish toxicity belong to medium toxicity. According to experimental results, it is well worth further research on the toxicity of inhalation and fish toxicity. |
