摘要

Fire suppression agents are recommended for extinguishing fires by flammable liquids and frequently end in water bodies, combined with the fuels. There is a lack of toxicity information on these commercial formulations and the effects of mixtures of fire suppression agents and fuels. The aim of the present study was to evaluate the toxic effects of different fire suppression agents, the gasoline water-soluble fraction (GWSF), and mixtures of each fire suppression agent and GWSF. Individual tests were performed with Daphnia similis and Artemia sp.; the most toxic fire suppression agents to D. similis and Artemia sp. were F-500 (R), Cold Fire (R), Agefoam (R), and Kidde Sintex (R) 1%; the GWSF was the least toxic. The concentration addition model was used to predict the mixture effects and evaluate synergism/antagonism, dose ratio dependence, and dose level dependence. Cold Fire with GWSF showed dose level deviation to D. similis, marked mainly by synergism; for Artemia sp., the dose ratio pattern was predicted, with a synergistic response mainly by Cold Fire. Agefoam and GWSF behaved additively for D. similis and dose ratio for Artemia sp., with synergism being caused by Agefoam. Kidde Sintex 1% with GWSF were dose ratio for both organisms, with Kidde Sintex 1% being responsible for synergism. Our results show that some mixtures of fire suppression agents and GWSF may cause toxicity to aquatic organisms, posing risk in a real environmental scenario, such as a major fire combat.

Similis和Artemia SP。是F-500（R），冷火（R），AgeFoam（R）和Kidde Sintex（R）1％; GWSF是最不毒性的。浓缩加法模型用于预测混合物效应和评估增量/拮抗，剂量比依赖性和剂量水平依赖性。 GWSF的冷火表现为D. Similis的剂量水平偏差，主要由协同作用标记;对于艾蒿Sp。，预测剂量比模式，主要是冷火的协同反应。 Agefoam和GWSF对于Artemia SP的D. Similis和剂量比表现剧性。，由Agefoam引起协同作用。 kidde sintex 1％的gwsf都是生物体的剂量比，kedde sintex 1％负责协同作用。我们的研究结果表明，一些灭火剂和GWSF的混合物可能对水生生物引起毒性，在真正的环境场景中造成风险，例如主要的火力战斗。环境毒素化学2020; 00：1-13。 （c）2020 Setac
