Biomass burning; ultrafine particles, concentration, and organ effect

Biomass burning has been known as a PM0.1 emission source that may have an impact on health. In this research, we investigate biomass burning ultrafine particles, PM0.1 in terms of the concentration and the exposure impact on mice organ. We used two biomass burning such as pine wood and grain straw burning. The smoke was exposed to the mice for 100 seconds, and the effect on the organ was observed including lung, kidney, liver, and erythrocytes. The effects on the organ damage were related to the PM0.1 dose concentration. The particle dose concentration was calculated by summing the total concentration of an ultrafine particle in the smoke. The PM0.1 concentration emitted by the pine wood burning was 1.4 × 106 particles/cm3 meanwhile, the concentration of the grain straw burning was 2.7 × 106 particles/cm3. We observed the exposure effects on the mice organ with the results as follows: every biomass burning produced PM0.1 with a certain concentration. The effects of biomass burning PM0.1 emission on organ depended on a kind of biomass and the particle dose concentration. Lung was the organ having the most effect on the biomass burning particle exposures among the other organ.
