An Forest Ecological Environment Impact Assessment of Forest Fire Suppression Chemicals -To Plants & Soil Organism-

Forest fires occur the world over, with large-scale fires constantly breaking out. A suppressant a type of forest fire chemical is widely used to respond to fires rapidly and effectively. In general, suppressants used for fires have been divided into dry powder, liquid, foam, and gel type, according to physical form and use. This study has conducted toxicity tests relating to phytotoxicity(Pinus densiflora seed germination rate and mortality of containerized seedling), and soil organism toxicity(earthworm acute toxicity tests), of these suppressants, with the loaded stream suppressant for direct forest fire extinguishing a Loaded Stream and foam concentrates generally being used in Korea. From the results of the tests, the loaded stream and the foam concentrate had an effect on the toxicity levels. In the case of the loaded stream type, it was observed that toxicity indicating a 100% lethality rate was found among all toxicity test methods. Therefore, it is determined that forest ecology environmental toxicity impact assessments related to the suppressant used to extinguish forest fires are necessary in the near future.
