- Abstract: Black carbon (BC) is the most strongly light-absorbing component of particulate matter and is largely emitted from the incomplete combustion of fossil and biomass fuels. It has a graphite structure with less carbonized, irregular, microcrystalline, and heterogeneous components, which is determined by pyrolysis conditions. BC can be absorbed by human body via inhalation or ingestion route and then be transported to various organs through the blood circulation system in human body. When crossing different biological barriers (such as blood-brain barrier, placenta barrier, and blood-testis barrier), BC may further act on these targets and induce various toxicities. This review first distinguished between BC and carbon black, and then introduced analytical methods of BC in various environmental samples: microscopic observation, chemothermal oxidation methods, other chemical oxidation methods, and molecular marker analysis. We summarized the principles, technical characteristics, and application to environmental samples of these methods, and discussed the ideas and perspectives of determination of BC in biological samples for human biomonitoring.
