“…In 2016, outdoor air pollution caused about 4.2 million premature deaths worldwide [63].The effects of PM exposure depend on their size and composition. Organic and elemental carbon concentrations present in PM have been associated with cardiovascular mortality and morbidity [16][17][18]64]. During the combustion or emissions of this carbonaceous fraction, toxic gases, volatile compounds, and hydrocarbons are generated, which are the cause of the deterioration of the respiratory and cardiovascular systems [19].…”

“…These carbonaceous aerosols have been considered an environmental problem because they affect human health and climate change. In terms of health effects, exposure to this substance can be associated with cardiovascular and respiratory diseases, cancer, and even, congenital malformations [16][17][18][19]. In the case of climate effects, elemental carbon, due to its special characteristic of strong absorption, contributes to the warming of the atmosphere and the darkening of the surface, disturbing or influencing the hydrological cycle through changes in variables such as latent heat, modifying circulation, and convection patterns [9].…”

The carbonaceous particles represent a significant fraction in the particulate matter (PM) and are considered an environmental hazard due to their effects on climate and health. The main goal in this research is to identify and analyze the scope that have been achieved so far on the characterization and measurement of the carbonaceous fraction present in PM, a great contribution to global pollution and thus to the deterioration of public health. The ProKnow-C methodology was used to build a bibliographic portfolio and perform a bibliometric and systemic analysis of the information found in the chosen databases. The contribution of these carbonaceous compounds to PM is very significant, reaching values up to 50%. The most used methods for the determination of organic and elemental carbon are thermo-optical reflectance and transmittance. Positive Factorization models are used worldwide to determine potential sources of particulate matter emissions. Even though various studies have been developed to understand these carbonaceous substances, there are several limitations in the measurements and limited knowledge on the subject. The positive outcomes and future possibilities were analyzed as well.
