Abstract The objective of this study was to develop a method for analyzing harmfulness of combustion products generated from material burning based on quantitative analysis. We conducted animal exposure experiment and performed quantitative analysis to analyze harmfulness of combustion products generated by material burning. Results of the experiment confirmed the limit of hazard analysis by toxicity index based on quantitative analysis of toxic gases. In the process of calculating harmful index of combustion products, we confirmed that the hazard of particulate matter should also be reflected. We also confirmed that existing criteria for judging harmfulness should be improved based on the amount of particulate matter generated. Results also confirmed that particle size and hazardousness of particulate matter were highly correlated. Results of this study demonstrate the necessity to study complex harmful analysis including particle size of particulate matter in the field of harmfulness of combustion products from material burning.
