[Figure 3] ¹⁴C-nanotracing approach for analyzing the organ distribution of black carbon-based fine particulate matter (IMAGE)
Caption
The research team conducted animal exposure experiments using ¹⁴C-labeled fine particulate matter to analyze its distribution across organs. The labeled particles were synthesized based on black carbon, one of the major components of fine particulate matter. Black carbon is produced by the incomplete combustion of carbon-based fuels such as coal and petroleum. Mice were then exposed to the labeled particles. The amount of fine particulate matter accumulated in each organ was precisely measured using accelerator mass spectrometry (AMS). Based on these measurements, the concentration and total amount in each organ were calculated to determine its distribution within the body.
