【 摘 要 】

The usage of aqueous film forming foam (AFFF) and other firefighting foams improves the effectiveness of firefighting operations and is considered as a significant factor for carrying out a successful firefighting action. As public awareness has increased, concerns have been raised about the impact AFFFs have on the environment in recent years. In this paper, the acute toxicity of AFFF to zebrafish was conducted to classify the acute toxicity level of 14 AFFF products from 7 different manufacturers on domestic market. The test results showed that the 96h LC50 values of 14 kinds of AFFF ranged from 232.57 to 5501.04 mg/L, which was comparable to foreign AFFF products. The products from different sources own different level of toxicity. For the AFFF products of the same formula system, the addition of alcohol-resistant components enhanced the acute toxicity of AFFF, while the addition of antifreezing components reduced the toxicity of AFFF.
